The information in this article is pulled from the following files in the JP and KR sources:

July 20th to August 1st#

003 - Venusaur

フシギバナから かれそうな ハナも
たちまち げんきになるという
ふしぎな ちからが にじみでてる。

The mysterious force exuding from
Venusaur can instantly revitalize
wilting flowers.

"Force" changed to "aroma" to match with Venusaur's Red & Green entry, with a slightly different word choice (滲み出る vs. 漂う).

007 - Squirtle

こうらの なかに とじこもったまま
なにも たべずに
なんにちでも たえることが できる。

It can stay cooped up in its shell
for days without having to eat
anything.

New information was replaced by an entry with details that were mostly covered already in Red & Blue.

010 - Caterpie

あたまの さきの しょっかく から
きょうれつな においを だして
てきを おいはらい みをまもる。

To protect itself, it emits an intense
odor from the antenna on the top of
its head that drives predators away.

Caterpie's antenna isn't on the top of its head, so the description was fixed.

011 - Metapod

いっしょうけんめいに そとがわの
カラを かたくしている。なかは
しんかのため どろどろ している。

It works hard to strengthen the outside
of its shell. Inside, it's mushy as it
prepares to evolve.

The old text was rewritten and used for Metapod's Silver entry.

012 - Butterfree

あしの さきに はえた うぶげに
ミツを ぬりたくっては じぶんの
すに もちかえる しゅうせいをもつ。

It has a habit of plastering the hairs
on the tips of its legs with honey to take
it back to its nest over and over.

The old entry is a bit more descriptive on where its hairs are.

014 - Kakuna

サナギと おもって ちかづくと
ハリをだして おそいかかってくる。
ねている わけではないのだ。

When something approaches it thinking
it's just a pupa, it extends its stinger and
attacks them. It's not really sleeping.

The old entry has a slightly more aggressive Kakuna.

018 - Pidgeot

おおがらで ぜんしんの きんにく
とくに むねの きんにくは すごい。
かるく はばたけば おおかぜになる。

Its whole body is muscular, with its pectoral
muscles being particularly amazing. A light
flap of its wings produces strong gales.

While in the old entry Pidgeot is muscular all over, the newer entries only mention its chest muscles.

019 - Rattata

どんな ものでも たべるので
エサとなるものが ある ばしょに
すみついて どんどん タマゴをうむ。

Since it eats anything, it make its nest in
any place where food is available, then
produces more and more eggs.

The last bit was changed from producing eggs to producing children.

020 - Raticate

なんでも かんでも かじってしまう。
コンクリートでできた たてものすら
かじり たおしてしまうほどだ。

It can gnaw on anything. It's even able
to chew through concrete buildings.

The old description doesn't describe how it can gnaw on anything, and it uses a different word for building (建物 vs. ビル).

022 - Fearow

いっきに おおぞらに まいあがり
そこから きゅうこうかで
いっきに おそいかかるのだ。

It rockets into the sky in an instant,
then dives down to attack its foe
in one fell swoop.

Minor rewording, but the content is basically the same.

024 - Arbok

じぶんよりも おおきな あいてを
まるのみ したときは とかしながら
ゆっくり ゆっくり あじわう。

When it swallows something bigger
than itself, it slowly savors their
flavor while dissolving them.

The rather grim details in the old entry were replaced entirely.

028 - Sandslash

いつも かわいた すなのなかで
せいかつ するので たたかったあと
あたりは すなっぽくなってしまう。

Since it usually lives in dry, sandy
places, the surrounding area will
get covered in sand after a fight.

Information on Sandslash's environment was replaced by info on Sandslash itself.

031 - Nidoqueen

じぶんの すに てきが ちかづくと
きずついたふりで す から はなれ
なかの こどもを まもろうとする。

When an enemy approaches its nest, it
feigns injury and attempts to lead them
away to protect its child(ren) inside.

Nidoqueen got a bit more foresight in how it protects its children after feigning injury.

034 - Nidoking

がんじょうな からだを つかって
どんどん たいあたり してくる。
ちからわざを このむ せいかくだ。

It uses its sturdy body to lunge at its
foe again and again. It's a Pokémon
that prefers to use brute force.

While the older text resembles its Yellow entry, the new text is more similar to its Red & Blue entry.

041 - Zubat

めのかわりに はったつした はなは
ポケモンの においを かぎわける
ちからに すぐれている。

Its nose is well-developed at the cost
of its eyes and can deftly distinguish
the scents of Pokémon.

The old entry doesn't really explain how it can safely move around without eyes.

042 - Golbat

どんなに かたい ひふでも
その するどい キバで つらぬいて
たっぷりと ちを すいまくる。

No matter how tough the victim's skin,
its sharp fangs can pierce through it
and suck out ample amounts of blood.

Its sharp fangs removed the redundant demonstrative sono it followed.

045 - Vileplume

あたまを ユサユサゆらし おおくの
どくかふんを ふりまく。だから
ラフレシアの まわりは あかっぽい。

It scatters a lot of toxic pollen around
by shaking its head. This makes the
area around Vileplume look ruddy.

The old entry was reused in Crystal, with the color changed from reddish to yellow.

048 - Venonat

おおきな りょうめは ひかりを
びんかんに かんじとれるので
よるでも あかるいところへ むかう。

Its large eyes are sensitive to light
and let it head towards brightly lit
places at night as well.

Both entries take information from its Red & Blue entry and expand it, they just use different parts.

049 - Venomoth

とんでいる ときには ゆっくりと
こうげきのときには はげしく
おおきな はねを はばたかせる。

It flaps its large wings
slowly when flying and
furiously when attacking.

The new entry no longer mentions how it flies and instead tells how its wingbeats work in attacks, which is consistent with Red & Green.

050 - Diglett

ひふが とても うすい。
ひかりに てらされると けつえきが
あつくなるので よわってしまう。

It is very thin-skinned. When light
shines upon it, its blood vessels
get hot and weaken it.

Entry merged into one sentence along with a minor rewarding for "heating" from 熱くなる to 温められる.

053 - Persian

ぜんしんから きひんが ただよい
あこがれる じょせいも おおい。
きのぼりや およぎも とくいだ。

Many women admire the elegance that
oozes from its every pore. It's also great
at climbing trees and swimming.

The old entry specifically mentions women, while the final entry expands this to all genders. Persian's affinity for climbing trees would only be mentioned in the old entry.

055 - Golduck

ひたいが ひかりかがやくとき
もてる のうりょくを
ぜんかいで はっき するらしい。

They say that when its forehead
glows, it's able to unleash its full
potential.

The forehead glow went from a sign that it can use its full potential to a sign that it is using its full potential.

056 - Mankey

じぶんより つよい あいてには
きのうえから いろんな ものを
なげつけて ていこう する。

It stands up to opponents stronger than
it is by throwing many different things
down at them from the treetops.

Mankey's monkey-like habit of throwing (possibly literal) crap at its foes was dropped from future entries.

057 - Primeape

ねていても ものおとが すると
すぐ とびおきて おこりだす。
そばに ちかよるのは むずかしい。

Even when it's fast asleep, if it hears
something, it'll spring awake in a
rage. Approaching it is difficult.

In the older entry, Primeape fully wakes up. In the new entry, not so much.

062 - Poliwrath

およぐとき いきおいが よすぎて
みずのうえまで とびだしてしまうほど
きんにくが はったつしている。

Its swimming muscles are so developed
that it'll jump out of the water if it swims
with enough momentum.

Both entries describe Poliwrath's swimming prowess, but the newer entry is definitely more impressive.

066 - Machop

いつも パワフル。たいりょくが
ありあまっているので いみもなく
いわをもちあげ さらに つよくなる。

It's full of pep. Since it has a lot of
excess energy, it gratuitously lifts
boulders and gets even stronger.

Minor rewording, but the content is basically the same.

067 - Machoke

どんなときでも ぜんりょくで
こうどう するけど それでも
つかれない タフな ポケモン。

It's a tough Pokémon that always gives
a hundred percent but never tires out.

An additional adjective in the newer entry.

069 - Bellsprout

ひょろっとした せかっこう だが
えものを とらえるときの うごきは
すばやく あっけに とられる。

It has a lanky physique, but it
moves astonishingly quick when
it's catching its prey.

Entries use different words to describe Bellsprout's figure (背格好 vs. 体付き).

073 - Tentacruel

80ぽんもの たくさんの あしは
すいぶんを ふくんでは
どこまでも のびていくらしい。

Its eighty legs are said to absorb
water and then stretch out as
far as they can.

Its legs' functions are now confirmed, with their purpose apparently for attacks.

076 - Golem

1ねんに 1ど だっぴをする。
ぬいだ かわは すぐにかたまり
ぼろぼろに くだけちる。

It molts once a year. The skin
it sheds quickly hardens, and
then crumbles to bits.

"Shell" is more accurate than "skin" for Golem. The thing's made of rock after all.

078 - Rapidash

かけぬけるとき その4ほんの あしは
ほとんど じめんに ふれていない。
それほどに はやく うごけるのだ。

When it runs, its four legs
barely touch the ground.
That's how fast it can move.

An unnecessary sono was removed from line 1.

079 - Slowpoke

みずべで ボーッとしている。
シッポに なにか かみついても
しばらくは きづかないくらいだ。

It lazes by the riverside in a mental fog.
Even if something bites its tail, it'll take
a while before it notices.

The new description more clearly defines Slowpoke's reaction time.

094 - Gengar

いちど あのよに いったことのある
ゴーストが ゲンガーに なるのでは?
といわれるが ウワサにすぎない。

Is it possible that a Haunter who's been to
the spirit world once could turn into a
Gengar? They say so, but it's only a rumor.

Wait a second, is the link cable a portal to the spirit world?! Oh, and the older entry also has a rare instance of a question in a Pokédex entry.

095 - Onix

からだを くねらせ よじらせ
ちちゅうを ほりすすむ。その おとは
はるか とおくまで なりひびく。

It twists and turns as it tunnels
through the earth. The din of its digging
echoes deep into the distance.

The new entry merges the two sentences together.

103 - Exeggutor

3つの あたまは かんがえることは
べつべつでも なかよし なので
ケンカしたり しないらしい。

The three heads may think differently,
but it seems that they don't quarrel with
each other because they're good friends.

The newer description actually introduces a typo on the third line.

104 - Cubone

かなしいとき さみしいとき
かぶっている ホネが ゆれて
やさしげで せつない おとがする。

When it's sad or lonely, the skull
on its head rattles and makes
a gentle, melancholy sound.

The sound's tone got more vulnerable and evocative of sadness with its shortness.

105 - Marowak

もっている ホネで いしをたたいて
おとをだし なかまに れんらくする
すがたが かくにん された。

It's been seen communicating
with its fellows by drumming
on rocks with its bone.

Different word for "appearance" in both entries (姿 vs. 様子).

112 - Rhydon

ようがんの あつさすら かんじない
がんじょうな ひふの もちぬし。
そのぶん にぶいところが あるのだ。

It has a sturdy hide that can even
withstand the heat of lava. That hide
is also what makes it so insensitive.

The noda at the end of line 3 was deleted.
にぶい means slowness in sensitivity in this context but can also imply that in motion or thinking; Rhydon fits all the three well.

128 - Tauros

ツノを つきあわせて たたかう。
つよい ケンタロスの
ツノは キズが たくさんだ。

They fight each other horn to horn.
There are many scars on the horns
of strong Tauros.

The bit about Tauros' scarred horns was expanded in the newer entry.

137 - Porygon

こきゅうを していないので
どんなところでも かつやく できる
はずの じんぞうポケモン。

Since it doesn't breathe, this synthetic
Pokémon should be able to work in any
environment.

A slight difference in Porygon's projected ability to work in any environment.

139 - Omastar

カラに こもった シェルダーも
その かたいキバで カラをやぶり
なかみを すいだしていたらしい。

It seems that it would use its hard
fangs to crack open the shells of
Shellder, then suck out their insides.

The old entry uses a different word for expressing doubt (らしい vs. ようだ) and has a different descriptor for Omastar's fangs.

148 - Dragonair

あめを ふらせる ちからをもつため
むかしから はたけしごとを まもる
かみさま として まつられている。

Due to its ability to summon rain, it's
been long revered as a protector
god for farm workers.

Dragonair went from a protector god to a protector Pokémon in farmers' rites, the first example of rewritten religious content.

149 - Dragonite

おぼれているひとを たすけた という
でんせつが おおく のこされている。
うみのかみさま として ゆうめい。

There are many tales of it coming
to rescue drowning people. It's
renowned as the god of the sea.

Another religious reference rewritten. Also, isn't that Lugia's title?

August 1st to August 17th#

Starting with Spaceworld 1999, both Gold & Silver got their own unique Pokédex entries. Almost all of the entries from the August 1st file made it into the SW99 version of Gold unchanged, but nine of them had some minor adjustments.

002 - Ivysaur

たいようの ひかりを
あびれば あびるほど
からだに ちからが わいてくる。

The more sunshine it gets, the
stronger its body gets.

Ivysaur's old entry doesn't mention its bud, which, given its other Pokédex entries, seems to be mandatory.

011 - Metapod

カラのなかは しんかの じゅんびで
とても やわらかく くずれやすいので
なるべく うごかないようにしている。

It is soft and fragile inside of its shell
as it prepares to evolve, so it avoids
moving as much as possible.

Entry was split into two sentences.

014 - Kakuna

サナギだが うごけないわけではない。
てきに おそわれそうになると
どくバリを だしてくることもある。

It's a pupa, but that doesn't mean it's
immobile. When an enemy threatens it,
it may extend its toxic stinger.

Rewritten to make it more clear that it can indeed move.

071 - Victreebel

たくさんの エサを とかした
ようかいえきは あまさが ますので
もっと エサを あつめやすくなる。

Its dissolvent is sweetened as it melts
down more and more food, which
makes it easier to attract new prey.

Small change at the end of line 2.

076 - Golem

1ねんに 1ど だっぴをする。
ぬいだ からは すぐにかたまり
ぼろぼろに くだけちる。

It molts once a year. The shell
it sheds quickly hardens, and
then crumbles to bits.

The old entry uses a different verb to describe the removal of the shell (脱ぐ vs. 脱ぎ捨てる).

083 - Farfetch'd

クキを なくした カモネギは
こうふん じょうたいに なので
うかつに ちかよると あぶない。

A Farfetch'd that has lost its stalk will
entr a state of panic, so approaching
it carelessly is dangerous.

A typo hotfix at the end of line 2.

096 - Drowzee

たのしいユメを みていた はずなのに
どんな ユメか おもいだせないとき。
きっと スリープに たべられたのだ。

Sometimes you'll have a pleasant dream
but can't remember what the dream was.
It must have been eaten by Drowzee.

The two sentences in the old entry were combined.

097 - Hypno

おなかが へっているとき
であった にんげんを むりやり
ねむらせ ユメを たべてしまう。

When it's hungry, it forcibly puts
people it encounters to sleep
and then eats their dreams.

Hypno is quicker to eat people's dreams in the older entry.

109 - Koffing

うすい まくじょうの からだに
なみだと せきが とまらなくなる
せいぶんの ガスで いっぱいだ。

Its thin, membranous body is filled
with gas, the components of which
cause nonstop crying and coughing.

The old entry was missing a ha at the end of the first line.

August 17th to Final (Gold)#

001 - Bulbasaur

せなかの たねの なかには
えいようが たっぷり。 たねは
からだと いっしょに おおきくなる。

The seed on its back is filled
with nutrients. The seed
grows along with its body.

There's an extra space after the first sentence. That's all.

003 - Venusaur

フシギバナから かれそうな ハナも
たちまち げんきになるという
ふしぎな かおりが ただよっている。

The mysterious aroma wafting out
from Venusaur can instantly revitalize
wilting flowers.

Venusaur's plant-healing power seems to have been transferred to Celebi. Also, how would they smell?

lnɟɹǝpuoM :∀

004 - Charmander

シッポの ほのおは せいめいりょくの
あらわれ。あめかぜでは きえないが
げんきがないと ほのおは よわまる。

The flame on its tail is a sign of its vitality.
It won't be extinguished by rain or wind,
but if it's not healthy, the flame fades.

The new entry gets rid of the text about rain and wind, though a similar detail appears in its Red & Blue entry.

008 - Wartortle

ながいきの シンボルと されている
ポケモン。こうらに コケがあるのは
とくに ながいきの カメールだ。

This Pokémon is considered a symbol
of longevity. There's algae on the shell
of especially old Wartortle.

Slightly different word choice (ある vs. ついている) but the content is basically the same.

009 - Blastoise

ふんしゃした みずの いきおいで
とばされないように わざと
たいじゅうを おもくしているのだ。

It deliberately weighs itself down
to avoid being pushed back by the
momentum from the water it sprays.

Slightly different word choice (飛ばす vs. 負ける) but the content is basically the same.

012 - Butterfree

あしに はえた うぶげに
ミツを ぬりたくっては じぶんの
すに もちかえる しゅうせいをもつ。

It has a habit of plastering the hairs
on its legs with honey to take it back
to its nest over and over.

Butterfree's honey-gathering changed from tendency to daily activity.

016 - Pidgey

ふだんは くさむらに かくれている。
たたかいは このまず おそわれると
はげしく はばたき みをまもる。

It's usually hidden in the grass. It doesn't
like to fight, but if it's attacked, it will
furiously flap its wings to defend itself.

Pidgey's method of defending itself was changed to match its Generation I entries.

023 - Ekans

エサを まるのみに するので
たべたあとは からだが おおきく
おもたくなって うごけない。

It swallows its food whole, but after
eating, its body becomes so bloated
and heavy that it can't move.

Ekans' body bloating is a certainty in the old entry, no matter how big the prey. It also fails to mention its ability to unhinge its jaw.

024 - Arbok

おなかの おそろしい かおもようを
みせつけ あしがすくんだ
ポケモンをしめつけ まるのみにする。

It displays the horrible facial features on
its belly, then constricts the cowering
Pokémon before swallowing it whole.

New entry clarifies that the markings on Arbok's belly aren't an actual face, and adds a mention of Arbok poisoning its prey.

025 - Pikachu

かたい きのみも でんげきで
やいてから たべるという グルメな
いちめんを もちあわせている。

It also has a gourmet side: It roasts
hard berries with thunder jolts
before eating them.

Pikachu's berry roasting changed from a matter of sophistication to intelligence.

028 - Sandslash

せなかのトゲは ひふの いちぶが
のびて かたまって できた。
おれやすいが すぐに はえてくる。

The spikes on its back were formed after
parts of its skin stretched and solidified.
They're fragile but grow again quickly.

The first part of Sandslash's old entry was reused in Ruby, while the info in the second sentence had already been mentioned in its Yellow entry.

031 - Nidoqueen

てきが じぶんの すに ちかづくと
きずついたふりをして とおくにはなれ
すの ばしょを かくそうとする。

When an enemy approaches its nest, it
feigns injury and attempts to lead them
far away to hide its nest's location.

An entry about Nidoqueen's distraction display was rewritten to describe Nidoqueen's bravery and scales.

033 - Nidorino

おおきな みみを たてて
あいての けはいを さぐる。
なにかあると すぐに とびかかる。

It uses its large ears to listen for
its opponents. When it hears
something, it leaps upon it.

Different word choice, but the content is basically the same.

034 - Nidoking

おおきなシッポを ふりまわし
あいてが ひるむと がんじょうな
からだで つっこんでくる。

It swings its large tail around. Then,
if its foe flinches, it charges at them
with its sturdy body.

Minor formatting change on line 1.

039 - Jigglypuff

きげんが いいと ふくらむ。
きげんが わるくても ふくらむ。
とおくからでは ちがいがわからない。

It puffs up when it's in a good mood.
It also puffs up when it's in a bad mood.
It's hard to tell the difference at a distance.

The rather humorous old entry was changed entirely. Jigglypuff inflating when it's happy doesn't match up with its potrayal anywhere else in the franchise.

040 - Wigglytuff

2ひき よりそって こうどうすると
おたがいの けがわが きもちよすぎて
はなれられなく なってしまう。

When two of them go along close together,
their fur feels so good against each other
that it's hard to separate them.

Minor rewording, but the content is basically the same.

041 - Zubat

めのかわりに はったつした はなで
まわりの においを かぎわけ
どんな ようすか はんだんしている。

Its nose is well-developed at the cost of its
eyes and is used to smell its surroundings
and see what's going on.

Zubat's entry was rewritten to stay consistent with its Gen I entries. Zubat don't got no nose. Or eyes.

046 - Paras

からだが そだつと せなかの
キノコが はえる。うまれたときから
ほうしが うえつけられているのだ。

As its body grows, so do the mushrooms
on its back. The spores were implanted
in its body when it was born.

The only major difference is mentioning how the spores get onto Paras' back.

047 - Parasect

くらくて しめった ばしょをこのむ。
それは ムシではなく おおきくなった
キノコの このみ なのだ。

It prefers to stay in dark, damp places.
This isn't a preference of the bug, but
of the giant mushroom.

The new entry (perhaps unnecessarily) specifies that the mushroom being mentioned is the one on its back.

048 - Venonat

りょうめは レーダーきのうを
そなえているので くらやみにかくれた
ちいさなムシも つかまえてたべる。

Its eyes have radar capabilities,
allowing it to catch and eat small
bugs that hide in the dark as well.

Entry was split into two sentences.

053 - Persian

ぜんしんから ただよう きひんに
あこがれる ひとも おおいが すぐに
ひっかくので やっかいな ポケモン。

Many people admire the elegance that oozes
from its every pore, but its quickness to
scratch makes it a troublesome Pokémon.

Entry rewritten, but the content is basically the same.

056 - Mankey

いつも きのうえで せいかつするほど
みがるで おこりだすと あらゆる
ほうこうから おそいかかってくる。

It's agile enough to stay in the
treetops, and with anger it'll come
at its aggressor from all sides.

Mankey's treetop existence was deleted from the final entry, though that tidbit appeared later on in Crystal.

059 - Arcanine

その どうどうとした すがたから
かみさまの つかいの ポケモンとして
しんじている ひとも おおい。

Its majestic appearance had led many
people to believe that this Pokémon is
a messenger of God.

This is even more overt than Dragonair and Dragonite's old entries! All this God talk was rewritten.

063 - Abra

1にちに 18じかんも ねむるのは
フルかいてん した のうみそを
やすめるために ひつよう だからだ。

It has to sleep for 18 hours a day
to rest its brain, which is always
operating at full speed.

The info in the old text was reused, more or less, for its Sapphire entry.

064 - Kadabra

じぶんの すごすぎる のうりょくを
りかい しているので めったに
ひとまえに すがたを みせない。

It understands the true extent of the
awesome powers it possesses, so
it rarely shows up in public.

Kadabra's powers were marginally toned down from the old entry.

067 - Machoke

どんなときでも ぜんりょくで
こうどうしても つかれたりしない
タフで じょうぶな ポケモン。

It's a tough and resilient Pokémon
that always gives a hundred percent
but never tires out.

Minor rewording, but the content is just the same.

068 - Machamp

4ほんの うでで じゆうじざいに
パンチを くりだせるのは
あしこしも がんじょう だからだ。

It's able to punch freely with
its four arms thanks to its
sturdy lower body.

Ever wonder how Machamp keeps its balance? Keep wondering, this probably isn't canon.

069 - Bellsprout

ひょろっとした からだつき だが
えものを とらえるときの うごきは
すばやく あっけに とられる。

It has a lanky build, but it moves
astonishingly quick when it's
catching its prey.

Bellsprout's speed is more concretely described in the newer entry.

072 - Tentacool

どくバリで さされた かしょは
あかく はれあがり とても いたく
いつまでも かゆみが のこる。

Any part that's hit by its toxic stingers
will be red, swollen, and very painful,
with an itchiness that lingers forever.

The old description is a little much, but the new entry is pretty grim too.

073 - Tentacruel

80ぽんもの たくさんの あしは
すいぶんを ふくんでは
どこまでも のびては からみつく。

Its eighty legs absorb water
and then stretch out as far
as they can to bind (its prey).

Jellyfish's mouth arms and tentacles are indeed informally referred to as ashi, but Pokédex shouldn't be informal.

077 - Ponyta

かろやかに そうげんを かけぬける。
しなやかな きんにくでの ジャンプは
たかい たてものも ひとっとびだ。

It gently runs through the prairies.
Its muscles are so limber that it
can easily leap over tall buildings.

The old text mostly goes over info from its Red & Green entry, while the final entry has new information.

079 - Slowpoke

みずべで ボーッとしている。
シッポに なにか かみついても
まる1にち きづかない。

It lazes by the riverside in a mental fog.
Even if something bites its tail, it'll take
an entire day before it notices.

Minor word order changes, but the content is just the same.

081 - Magnemite

じりょくに ひかれる せいしつが
あるらしく でんしゃに
ちかづくことも すくなくない。

It seems to be attracted to magnetic
forces; it is not uncommon for it to
approach electric trains.

Magnemite's attraction changed, so the example of its attraction had to change too.

082 - Magneton

3つのコイルは つよい じりょくで
むすびついているらしく そばによると
つよい みみなりに おそわれる。

It seems that the three Magnemite are
connected by a strong magnetic force;
getting too close can cause tinnitus.

Entry was split into two sentences, and the "seems to" was removed.

083 - Farfetch'd

クキを なくした カモネギは
こうふん じょうたいに なるので
うかつに ちかよると あぶない。

A Farfetch'd that has lost its stalk will
enter a state of panic, so approaching
it carelessly is dangerous.

The idea of Farfetch'd panicking after losing its stalk seems to have been abandoned.

085 - Dodrio

3ばいの じょうほうを あつめて
こうどな さくせんを ねる。
たまに かんがえすぎてしまう。

It gathers three times as much data
and devises sophisticated strategies.
It may overthink things.

An extra detail on Dodrio's analysis paralysis was added after Spaceworld 99.

086 - Seel

ちじょうでは よちよちあるき だが
すいちゅうだと どんな ながれでも
じゆうじざいに およぎまわれる。

It waddles around on land, but when
it's in the water, it can swim around
freely in any current.

Seel's old entry is missing a bit on it enjoying cold waters.

087 - Dewgong

からだは みずの ていこうが
すくない りゅうせんけい。
みずのなかでは はなを とじている。

Its streamlined body has little drag
in the water. When it's underwater,
it keeps its nose closed.

Do you get that the Seel line likes cold water yet?

089 - Muk

たいないで さまざまな どくが
まざって あたらしい しゅるいの
どくが うみだされていく。

Various toxins mix together in its
body and end up producing new
types of toxins.

The data in Muk's entry never appeared in future titles, but did come back (in a way) with Alolan Muk.

090 - Shellder

2まいのカラを あけたり とじたり
それを くりかえすことで
うしろむきに およいでいく。

It swims backwards by repeatedly
opening and closing its two valves.

New entry adds a new sentence describing Shellder's speed.

092 - Gastly

うすい ガスのような からだなので
どこにでも しのびこめる。
でも かぜで ふきとばされてしまう。

Its thin, gaseous body lets it sneak
in anywhere. But, the wind blows it
away.

The two sentences in the old entries were combined.

093 - Haunter

ほんとうに なにも みえない
やみで ゴーストは しずかに
えものを ねらっているのだ。

In the darkness, where nothing is visible,
Haunter is quietly targeting its prey.

The old entry uses a different word for darkness. 暗闇, which the new entry uses, specifically refers to a physical absence of light, while 闇 could be interpreted as a metaphysical darkness.

096 - Drowzee

たのしいユメを みていたはずなのに
どんなユメか おもいだせないときは
きっと スリープに たべられたのだ。

If you had a pleasant dream but
can't remember what the dream was,
it must have been eaten by Drowzee.

The entry was split back into two sentences, reverting the Spaceworld '99 change.

097 - Hypno

とても おなかが すくと
であった にんげんを むりやり
ねむらせ ユメを たべてしまう。

When it gets very hungry, it forcibly
puts people it encounters to sleep
and then eats their dreams.

Tense change on line 1.

099 - Kingler

あまりにも おおきくなりすぎた
はさみは もちあげるのが やっと
ねらいなんか うまく つけられない。

Its pincers are so overgrown
that it has trouble lifting them,
let alone aiming them properly.

A de particle was added to the end of line 2.

109 - Koffing

うすい まくじょうの からだには
なみだと せきが とまらなくなる
せいぶんの ガスで いっぱいだ。

Its thin, membranous body is filled
with gas, the components of which
cause nonstop crying and coughing.

Not content with crying and coughing, the devs went for the allergy trifecta.

110 - Weezing

たいないの どくガスは くうきより
すこし かるい せいぶん。だから
いつも すこしだけ うかんでいる。

The toxic gases in its body are
a bit lighter than air. That's why
it's always floating a little.

The old description was reused as Koffing's Silver entry.

111 - Rhyhorn

4ほんの あしは みじかくて
うまく まがれないので
ただひたすらに とっしんするだけだ。

Its four legs are too short for it
to turn properly, so all it can do
is charge straight ahead.

Entry was split into two sentences.

113 - Chansey

もっている タマゴを
わらないように きをつけて あるく。
でも にげあしは とっても はやい。

When it walks, it's careful not to break
the egg it's carrying. However, it can
still run away very quickly.

There's a little more emphasis placed on the old entry's word for "very", とっても, than the new entry's とても.

117 - Seadra

さいぼうを しらべると タッツーには
なかった ドラゴンの いでんしが
はっけんされ わだいと なっている。

It's become a hot topic of discussion after a
cellular examination revealed a draconic
gene not present in Horsea.

Both descriptions are supposed to hint at Seadra's new evolution, Kingdra.
The old one might be too obvious, but the new one might not be obvious enough.

120 - Staryu

よるになると からだの ちゅうしんが
ゆっくりと てんめつする。
ひとの こどうと おなじ リズムだ。

At night, the center of its body slowly
flashes. It has the same rhythm as a
human heartbeat.

The two sentences in the old entries were combined.

122 - Mr. Mime

おかしなうごきで てきを まどわす。
うまれつきの のうりょくで
そだつほど じょうたつ する。

It misleads its foe with strange movements.
This inborn ability improves as it matures.

Its ability to mislead people was already mentioned in Red & Green, so that bit was replaced with a new fact.

123 - Scyther

くさむらの なかで じっと
いきを ひそめている。どんな
のうりょくでも さがしだせない。

It hides in thick grass, holding its breath.
No matter how hard someone looks, it
cannot be detected.

A cut-down version of the old text made its way into part of Scyther's Silver entry.

124 - Jynx

リズミカルに からだを うごかす。
そのときの かんじょうに よって
リズムは かわってくるらしい。

It moves its body rhythmically. The
rhythm seems to change based on
how it's feeling at the time.

Slight rewording (動かす vs. 揺らす, 変わる vs. 異なる) but the content is basically the same.

127 - Pinsir

よるは ツノをつかい じめんを
ほって ねむる。あさはやくだと
ひふに しめった つちがついている。

At night, it uses its horns to dig into the
ground and sleep. In the early morning,
damp soil sticks to its skin.

The new description clears up that Pinsir will sleep inside the ground into which it dug.

129 - Magikarp

みずの あるところなら どこででも
はねている。たまに いきおいよく
はねすぎて みずのそとにでてしまう。

Wherever there's water, it can be found
jumping around. Sometimes it jumps
too hard and ends up out of the water.

The old text doesn't mention how weak Magikarp is, so that's no good. The new text also gives a more definitive assessment of Magikarp's jumping prowess.

130 - Gyarados

むかし いくさが おこるたびに
ギャラドスが あらわれ あちこちを
ひのうみに していった という。

It's said that in the past, whenever war
broke out, Gyarados would apppear
and turn the land into a sea of fire.

Slight rewording, but the content is pretty much the same.

131 - Lapras

やさしさと きひんに あふれる
うみの ポケモン。ひとを のせて
うなばらを いくのが だいすき。

A sea Pokémon brimming with tenderness
and grace. It loves to carry people across
the ocean on its back.

While the entry was rewritten, neither entry really says anything that other Gen I entries didn't already mention.

132 - Ditto

たんじゅんな さいぼうそしき。
だから いっしゅんで あいて
そっくりに へんしん できる。

It has a simple cellular structure.
That's why it can instantly transform
into an exact copy of its foe.

This is the only reference to Ditto's simple cellular structure being the reason it can transform.

133 - Eevee

どんな かんきょうでも すごせるよう
さまざまな しんかの
かのうせいを ひめている。

It has the potential to evolve in
many different ways to adapt
to any environment.

While both entries say around the same thing, only the old entry specifically mentions evolution.

134 - Vaporeon

みずに とける のうりょくを
もっているが にごった ばしょでは
その のうりょくを つかわない。

It has the ability to melt into
water, but it won't use that
ability in muddy places.

An expansion on Vaporeon's previously mentioned ability to liquify was replaced with totally new information.

135 - Jolteon

さいぼうが だしている よわい
でんきを ひとまとめにして
ほうしゅつして こうげき する。

It concentrates the weak electricity
its cells emit, then attacks by
discharging it.

The new entry makes sure that its discharges are strong and capable of out-of-battle uses.

137 - Porygon

こきゅうを していないので
どんなところでも かつやく できると
きたい される じんぞうポケモン。

Since it doesn't breathe, this synthetic
Pokémon is expected to work in any
environment.

The old entry uses the wrong term for artificial. じんこう is the correct term for an artificial version of something that already exists in nature, e.g. a Pokémon.

145 - Zapdos

かみなりぐもに つつまれている。
だから すがたを みられないと
つたえられる でんせつの ポケモン。

It's shrouded in thunderclouds. That's
why this legendary Pokémon is said
to be impossible to see.

Entry was rewritten to fit the Generation II trend of Pokémon causing weather events through mundane actions.

148 - Dragonair

あめを ふらせる ちからをもつため
むかしから はたけしごとを まもる
ポケモン として まつられている。

Due to its ability to summon rain, it's
been long revered as a Pokémon
that protects farm workers.

After getting downgraded from a god to a protector, someone decided to just completely rewrite the entry.

149 - Dragonite

うみで おぼれている ひとを
たすけるため ひろい うみを
いつも パトロールするという。

They say it's always patrolling
the ocean to rescue people
who are drowning at sea.

The old description used the English word "patrol" instead of 飛び回っている.

Additionally, Clefairy and Clefable switched entries, Poliwhirl & Gengar's SW99 Gold entries were moved to the final Silver, and their SW99 Silver entries were moved to the final Gold.

August 17th to Final (Silver)#

009 - Blastoise

こうらの ロケットほう から
ふきだした ジェットすいりゅうは
コンクリートの かべもつらぬく。

The rocket cannons on its shell
shoot out jets of water that can
even penetrate concrete walls.

Someone cranked up the pressure on Blastoise's cannons.

010 - Caterpie

てきが おそわれそうになると
きょうれつな においがする
しょっかくを だして みをまもる。

When an enemy is about to attack,
it will defend itself by emitting a
pungent smell from its antenna.

Many Silver entries in the Spaceworld 99 demo are just rewritten versions of their Gold entries.
All of these were changed by the final game.

012 - Butterfree

ハネに ついている りんぷんは
みずをはじく。あめが ふっていても
ミツを あつめるため とびまわる。

The scales attached to its wings
repel water. Even when it rains, it
still flies around, gathering honey.

Butterfree's ability to fly in the rain was heightened to flying in heavy rain.

018 - Pidgeot

うつくしいハネは ひろげて
あいてを いかく するだけでなく
マッハ2で そらをとべる。

Its beautiful wings aren't just for
spreading to intimidate enemies;
they also allow flight at Mach 2.

Minor spacing change on line 1.

024 - Arbok

おそろしい かおのような もようは
からだが おおきくなるごとに
びみょうに へんか するらしい。

The horrible face-like pattern seems
to change slightly as it matures.

The concept of the face pattern changing with age dropped. The new entry is actually Dunsparce's SW99 Silver entry, repurposed for a more appropriate Pokémon after its personality changed.

025 - Pikachu

シッポをたてて くうきちゅうの
でんきを あつめ ほっぺたの
でんきぶくろに たくわえる。

It raises its tail to collect the
electricity in the air, then stores
the electricity in its cheek pouches.

The text was rewritten to be consistent with its Yellow entry.
Its later Sapphire entry states that Pikachu charges in its sleep, not by raising its tail.
However, the early method of gathering electricity is mentioned in Raichu's Crystal entry.

026 - Raichu

たくさんの でんきを ためられるから
ピカチュウよりも みじかい じかんで
すごい でんげきを はなつ。

Since it can store a ton of electricity, it
can fire off an enormous thunder jolt
in a shorter period of time than Pikachu.

Raichu's entry was changed due to intimidation from the powerful pro-Pikachu lobby.

028 - Sandslash

せなかのトゲは ひふが かたまって
できた。たたかいで おれても
つぎのひ すぐに はえてくる。

The spikes on its back were formed from
solidified skin. If a spike snaps off in a fight,
it will grow again right away the next day.

Another reworded Gold description was included with more clarified speed of growth in the final game.

029 - Nidoran♀

おとなしい せいかくで たたかいは
このまないが いざと いうときは
ツノのどくで あいてを くるしめる。

It's meek and doesn't like to fight, but
when push comes to shove, it will
torment its foe with its toxic horns.

Entry reworded, but the content is basically the same.

031 - Nidoqueen

おおきく がんじょうな からだで
すあなの いりぐちを ふさぎ
てきから こどもを まもる。

It uses its large, sturdy body to block
the entrance to its nest and protect
its child(ren) from predators.

The word kodomo is one of the Japanese nouns most interchangeable among countable/single, mass, and collective/plural (it was plural centuries ago); tachi following it pluralizes it clearly.

036 - Clefable

ちいさな おとも きこえるため
しずかな やまおくで
ひっそりと くらすと いわれている。

They say that it lives quietly in quiet,
remote mountains because it can
hear even the smallest of sounds.

Old description doesn't mention its ears, but they should be apparent by just looking at its sprite.
It would later distinguish the smallest of differences between the final Gold and Silver entries, and see its mountainous habitat mentioned in its Crystal entry.

037 - Vulpix

さいしょは しろくて 1ぽんの
しっぽは そだつごとに わかれていき
そのたびに のうりょくが たかまる。

It starts out with a single white tail,
but as it matures the tail splits, and
it gets more powerful each time.

No future entries mention Vulpix getting stronger each time its tail splits, so that seems to have been dropped.

038 - Ninetales

9ほんの うつくしい しっぽには
1000ねん いきるための
ふしぎなエネルギーが つまっている。

Its nine beautiful tails possess a
mysterious energy that allows it
to live for a thousand years.

The newer entry got more excited at the amount of the energy.

041 - Zubat

くらいところで せいかつ するので
ちょうおんぱを だして まわりの
じょうきょうを しらべる。

It lives in dark places, so it emits
ultrasonic waves to check its
surroundings.

Old entry mentions using ultrasonic waves, but not in relation to Zubat's flying.

042 - Golbat

いちどに 300シーシーの ちを
すえるが すいすぎると からだが
おもたくなって ふらふら する。

It can suck up to 300 cc of blood
at a time, but if it sucks too much,
it will become heavy and wobbly.

Word order change, but the contents of both entries are pretty much the same.

043 - Oddish

つきのひかりを あびて うごきだす。
よるのあいだに あちこち タネを
ばらまくために あるきまわる。

It starts moving in the light of the moon.
During the night, it roams to sow its seeds
from place to place.

Minor word order changes, but the content is basically the same.

045 - Vileplume

はなびらが おもすぎるため
あるくと ふらふら する。そのたび
どくの かふんが ばらまかれる。

Its petals are so heavy that it wobbles
when it walks. Every time it wobbles,
it disperses poisonous pollen.

The old entry is a reworded Gold entry, while the new text is based on its Red & Green and Yellow entries.

047 - Parasect

くらく じめじめ したところに
せいそく しているのは それが
せなかの キノコの このみだからだ。

The reason it lives in dark, damp
place is because that's what the
mushroom on its back prefers.

Silver copied Gold's paper and hoped it wouldn't get caught. It did.

048 - Venonat

めが レーダーのやくわりを するので
くらやみこかくれた ちいさなムシも
みつけだして たべてしまう。

Since its eyes function like radar, it's
able to find and eat small insects
hiding in the darkness as well.

Half of Venonat's entry is new, while the other half remains from its older, Gold-copying entry.

050 - Diglett

だれも てあしを みたことがない。
どうやって じめんを ほっているのか
いまだに わからないままだ。

No one has ever seen its arms or
legs. How it's able to dig through
the ground is still a mystery.

This would have been the first in-game mention of Diglett's arms and legs (or lack thereof).

053 - Persian

その しなやかな うごきは
あしおとひとつ たてずに あるける。
いっしゅんで えものを かる。

Its lithe movements allow it to walk
without making a single sound. It
captures its prey in a flash.

The new entry is more interested in its muscles and agility.

056 - Mankey

みのこなしが かるく きのうえで
せいかつする。おこると あたまの
うえから おそいかかってくる。

It's light on its feet and lives in the
treetops. When it gets angry, it
attacks its aggressor from above.

Another thing that makes Mankey angry: Reworded Gold descriptions.

057 - Primeape

アドレナリンが ぶんぴつ しやすく
いつも おこっていて めがあうと
どこまでも おいかけてくる。

It's prone to produce adrenaline and
stays angry; if anyone makes eye
contact, it chases them as far as it can.

A mention of adrenaline was deleted from Primeape's entry.

060 - Poliwag

すべすべのひふは とてもうすくて
ないぞうの いちぶが すけてみえる。
むきは ちほうによって ことなる。

Its smooth skin is so thin that parts
of its internal organs are visible.
Their orientation varies by region.

Both parts of the older entry were stated in Gen I entries, while the new entry expands on the spiral orientation.

062 - Poliwrath

ぜんしんの きんにくを いかした
ダイナミックな およぎが とくいだが
なぜか ちじょうで せいかつする。

It's a dynamic swimmer that makes
full use of all of its body muscles,
but for some reason it lives on land.

Minor rewording, but the content is more or less the same.

063 - Abra

じぶんの すみかは のうみそに
きざみこまれているので どんなときも
テレポートで もどれる。

The location of its home is imprinted
in its brain, so it can teleport back
there at any time.

Another bit of information that is only mentioned in the old entry and nowhere else.

065 - Alakazam

のうさいぼうは いつも ぶんれつして
しぬまで ふえつづけるので
あらゆることを きろくできる。

Its brain cells continue to divide
and multiply until it dies, allowing
it to document everything.

While document/record is technically correct, "remember" would be a better fit here.

066 - Machop

ぜんしんの きんにくを すこしでも
ふとくするため けわしい やまおくで
しゅぎょうに あけくれている。

It spends all of its time training in
the rugged mountains to make every
muscle in its body as bulky as possible.

Machop's mountainous training grounds were later mentioned in its Crystal entry.

067 - Machoke

1にちじゅう ぜんりょくで
うごいても つかれることを しらない
きょうじんな からだの もちぬし。

It has a strong body that never tires
out, even when it acts at full strength
all day long.

Machoke tires of reworded Gold entries.

068 - Machamp

4ほんの うでは かんがえるよりも
さきにうごくので 2びょうかんに
1000ばつの パンチをくりだせる。

It has four arms that can move faster
than it can think, so it can deliver a
thousand punches in two seconds.

The idea of Machamp moving faster than it can think was reused in its Crystal entry.

069 - Bellsprout

あしを じめんのなかに のばして
すいぶんを ほきゅうする。そのとき
おそわれると にげだせない。

It plants its feet into the ground to
rehydrate. If it's attacked at that
time, it won't be able to escape.

"Deep" was probably added to explain why it can't just pick its feet out of the ground to escape.

070 - Weepinbell

くちよりも おおきな えものは
きれあじ するどい ハッパで
きざんでから たべるようにしている。

It has a habit of chopping up any
prey larger than its mouth with sharp
leaves before eating them.

New entry shows that it'll make no leftovers.

071 - Victreebel

ミツのにおいに むらがった ものは
すべて くちのなかで とかしてしまう
きょうぼうな しょくぶつポケモン。

A violent plant Pokémon that attracts
prey with an aroma of honey, then melts
anything that approaches in its mouth.

An unnecessary は was removed from the end of the first line.

073 - Tentacruel

80ぽんの しょくしゅは
ふだんは みじかい。たたかいのとき
すいぶんを すって ながくのばす。

Its eighty tentacles are usually
short. During a battle, they absorb
water and stretch out much further.

Most of Tentacruel's old entry is from Red & Blue, with the other part copied from Gold.

074 - Geodude

やまみちなどで じっとしている
ことが おおく きづかずに
ふみつけると はげしく あばれだす。

It tends to stay still on mountain trails,
but if someone steps on it without
noticing, it will rampage violently.

The old entry is almost identical to its Yellow entry, while the final entry has new information.

076 - Golem

がんせきのように かたい からだを
つかって くりだされる
こうげきは はかいりょく ばつぐん。

The attacks it launches with its hard,
rock-like body are highly destructive.

An entry describing Golem's destructive force was changed to something far sillier.

077 - Ponyta

はいごに けはいを かんずると
ダイヤモンドより かたい ひずめの
うしろあしで けりあげてしまう。

If it senses any presence behind it,
it will kick back with the harder-than-
diamond hoophs on its hind legs.

Hoof is misspelled in the older entry.

078 - Rapidash

すごい かそくりょくで
たったの 10ぽも かければ
さいこうじそく 240キロになる。

It has great acceleration; in just
ten steps, it can reach its top
speed of 240 km/h.

Both entries have the same fact, but the new entry seems a lot more excited about it.

079 - Slowpoke

シッポのさきから あまみが
にじみでている。えいようは ないが
かんでいると しあわせな きぶん。

A certain sweetness oozes from the tip of
its tail. It's not nutritious, but if someone
chews on it, it'll make them happier.

Small formatting change on line 1.

080 - Slowbro

もともと かんかくが にぶかったが
シェルダーの どくそが しみこみ
いたさを かんじなくなってしまった。

Its senses were dull to begin with, but
after Shellder's toxins seeped into its
system, it happened to get impervious to pain.

An excessive shimau at the end was removed.

081 - Magnemite

さゆうの ユニットから
じゅうりょくを さえぎる ちからで
だすので くうちゅうに うかべる。

The two units at its sides generate of a
gravity-blocking energy that allows it
to float in the air.

A typo hotfix at the end of line 2. That looked as if Magnemite had been to generate another stuff with the energy.

082 - Magneton

おたがいの コイルを むすびつける
じりょくは まわりの おんどを
2ど あげるほど きょうりょく。

The magnetic force that connects each
Magnemite is so powerful that it warms
up the surrounding air by two degrees.

The two degree temperature rise was already mentioned in Yellow, so it was replaced with something cooler.

084 - Doduo

あしあとの ふかさは 10センチに
なるほど じめんを ちからづよく
ふみしめ そうげんを かけぬける。

It races across the grassland, stomping
the ground so powerfully as to leave
footprints 10 cm deep.

The new entry gets excessively excited at its footprints.

090 - Shellder

2まいの カラを とじるとき
ジェットすいりゅうが はっせい。
その いきおいで およぐ。

When it closes its two valves, it
generates a jet of water. It swims
with the resulting momentum.

An entry that just reiterated stuff in Gold was changed to explain how the Shellder line got their held items.

092 - Gastly

からだが うすい ガスで
できているので かぜの つよいひは
すがたを みせないと いわれている。

Its body is made of a thin gas,
so it's believed it won't appear
on windy days.

Old entry expands on the Gold entry, while the new text goes over facts already stated in Generation I.

098 - Krabby

おおきな てきに おそわれると
くちから あわをだして じぶんも
おおきく みせようと こころみる。

When it's attacked by a larger enemy,
it tries to make itself look bigger by
blowing bubbles from its mouth.

Reusing content from Gold makes me some kind of synonym for irritated. Possibly one that's spelled wrong.

100 - Voltorb

ころがっているときの まさつで
はつでん する。でんきが
たまりすぎると ばくはつ する。

The friction from rolling generates
electricity. If it builds up too much
electricity, it will explode.

Voltorb already had a lot of design flaws, but the one in the old entry was thankfully scrapped.

104 - Cubone

しにわかれた ははおやの ホネを
いつも かぶっているので
どんな すがおか わからない。

It's always wearing the skull of its
dead mother, so no one knows
its real face.

Both entries have the same fact, but the new entry reads a bit more clearly.

105 - Marowak

どこからか ホネを ひろってくる。
せかいの どこかには ガラガラだけの
はかばが あるという ウワサだ。

It collects bones from somewhere. It's
rumored that somewhere in the world,
there's a graveyard of only Marowak.

An excessive ha was removed from second line.

106 - Hitmonlee

れんぞくで キックを はなつうちに
りょうあしが だんだん のびてきて
とおくの あいても けれる。

As it starts repeatedly kicking,
both of its legs gradually extend
and it's able to kick farther.

Hitmonlee's legs extend faster in the final entry.

108 - Lickitung

ながい したは ねばねばした
だえきで べっとり。どんなものでも
くっつくので とても べんり。

Its long tongue is coated in sticky
saliva. It's very useful because it
sticks to anything.

Minor attitude change on line 3.

109 - Koffing

きおんが たかくなると たいないの
どくガスが ぼうちょう して
おおきく ふくらんでいく。

As the temperature rises, the
toxic gases in its body expand
and it greatly swells in size.

Old entry has material already covered in Yellow, while the final entry has new info.

110 - Weezing

2しゅるいの どくガスを まぜて
きょうれつな どくガスを つくりだす
ふたごの ドガース。

The Koffing twins mix two types
of toxic gas together to create
a more powerful toxic gas.

The concept of mixing gases together to make a more powerful gas was revisited for its Sapphire entry.

111 - Rhyhorn

ちのうは おまり たかくないが
その とっしんは こうそうビルすら
こわせるはど きょうりょくだ。

It's not very intelligent, but its
charge is so powerful that it
can even destroy a skyscraper.

The old text is basically lifted from Red & Green, while the final text expands on its Yellow entry.

113 - Chansey

かずが すくなく つかまえることが
できた トレーナーには
しあわせを もたらすと いわれる。

They're few in number, and it's said
to bring happiness to the trainer
who was able to catch it.

The final entry adds on the difficulty.

114 - Tangela

たいようの ひかりを あびれば
あびるほど ぜんしんをおおう ツルは
どこまでも のびつづけるのだ。

The more it basks in the sun's rays,
the more the vines that cover its
body continue to grow.

Its Yellow entry states that the vines never stops going, but doesn't link to sunlight like the old entry does.

119 - Seaking

ツノをつかって かたい いわをほる。
タマゴが ながされないように
するための やさしさだ。

It uses its horn to drill into a hard
boulder. That's how it gently keeps
its eggs from washing away.

Both entries have the same fact, but the old entry praises its kindness and ends up skimping on the details.

122 - Mr. Mime

ゆびさきから つねに だされる
ふしぎな ねんぱが くうきを
かためて ほんとうの かべをつくる。

It constantly produces mysterious
waves from its fingertips to solidify
air and create actual walls.

The two entries use a different word for waves:
The old entry uses ねんぱ as with Psywave's, which it can learn;
The final's はどう is used by most wave- and pulse-type attacks in the series, none of which can it learn.
Its はどう would appear several times and be translated as "force field" in Silver/SoulSilver, "[e]manations" in Pearl and X, and "auras" in Shield.

124 - Jynx

どくとくの リズムかん。
どんなときでも おどるように
ぜんしんを くねらせている。

It has a unique sense of rhythm. At
any given moment, it's twisting and
turning its body as if it were dancing.

Another old Silver entry cribbed from an earlier Yellow entry.

127 - Pinsir

ながい ツノを ふりまわして
こうげきしてくる。さむいときは
もりの おくに すがたをかくす。

It attacks by swinging its long horns.
When it's cold out, it hides deep in
the forest.

Minor formatting change on line 2.

128 - Tauros

3ぼんのしっぽで じぶんをたたき
せんとういよくを たかめると
いっきに つっこんでくる。

It gets motivated to fight by whipping
itself with its three tails, then charges
at its foe at once.

Different wording, but is the content basically the same? Yes.

129 - Magikarp

とにかくはねる。いみもなく はねる。
たまに いきおいよく はねすぎて
じぶんでも おどろいてしまう。

It jumps regardless. It jumps at random.
Sometimes it jumps so hard that it
suprises itself.

Magikarp jumped too close to the sun and paid for its hubris.

130 - Gyarados

いちど しゅつげん すると
まわりを すべて やきつくさないと
いかりが しずまらないのだ。

Once it makes an appearance, it
needs to burn anything around it
to quench its rage.

Gyarados' rampage went from fact to hearsay.

131 - Lapras

ひとの ことばを りかいするため
たくさん つかまえられ
いまでは ぜつめつ すんぜん。

It's because it can understand human
language that many have been caught
and they're now nearly extinct.

Old text mixes its Red & Green entry with its Gold entry, while the final text has the first mention of it singing.

132 - Ditto

シンプルな さいぼうそしき。
どんな かたちにでも いっしゅんで
へんしん することが できる。

It has a simple cellular system.
It can instantly transform into
any shape.

Just because Ditto can copy anything doesn't mean you can copy its Gold entry.

133 - Eevee

おおくの しんかの かのうせいを
もつのは どのような かんきょうにも
たいおう するための ほんのうだ。

It's the ability to adapt to any
environment that gives it so
much evolutionary potential.

Seems to be some kind of chicken and egg situation going on in these entries.

137 - Porygon

プログラムで できた からだは
でんせんを つたわって
すきなところへ いどうできる。

Its program code-based body can
travel through electrical wires and
go wherever it pleases.

Porygon travelling through cyberspace has been mentioned previously, but not electrical wires.
Could this be a scrapped Pulseman reference?

138 - Omanyte

うみのみずを すっては はきだして
エサとなる プランクトンを あつめて
たべていたらしい こだいのポケモン。

An ancient Pokémon that seems to
have collected plankton to eat by
sipping and spitting out sea water.

In an odd twist, the old entry has new information, while the new entry is just its Yellow entry rewritten.
Omanyte's plankton-based diet was mentioned later in its Crystal entry.

140 - Kabuto

かいていで プランクトンを たべて
せいかつ していたと いわれる
おおむかしの ポケモン。

A Pokémon from long ago that is said
to have lived on the ocean floor,
eating plankton.

The final entry introduces the idea of Kabuto that still live in the wild. Its diet remains unknown to this day.
Why are both of these entries about plankton?!

142 - Aerodactyl

かんだかい こえで さけびながら
こだいの おおぞらを とんでいたと
いわれる どうもうな ポケモン。

A ferocious Pokémon that is said to
have flown through the ancient skies,
screaming high-pitched cries.

Slightly different wording for hearsay (といわれる vs. とされる).

143 - Snorlax

いぶくろの しょうかえきは
どんな どくも しょうか できるから
おちているものを たべても へいき。

The digestive juices in its stomach
can dissolve any poison, so it can
eat anything that fell on the ground.

Entry was split into two sentences.

144 - Articuno

くうきちゅうの すいぶんを こおらせ
ゆきを ふらせながら とんでいく
でんせつの とりポケモン。

A legendary bird Pokémon that
freezes the moisture in the air
as it flies, which makes it snow.

New entry elaborates that Articuno is one of several legendary bird Pokémon.

148 - Dragonair

すいしょうの ような タマには
てんきを じゆうに あやつる
のうりょくが ひめられているらしい。

It's said that its crystalline orb has the
power to freely control the weather.

The old entry uses a different word for weather - 天候 instead of 天気. In this case, 天気 is correct, since the entry refers to the weather at a specific time and not general weather.
