A very rough Logo draft was shown in Pokémon Fan Magazine 2003.
Early Screenshots
Screenshots found on gaming websites and print publications prior to the game's release show a few differences from the final.
Early Wes Model
This striking prototype of protagonist Wes showcases a dramatically different look:
Stark white spiky hair
Piercing red eyes with sharp angular features.
This is in contrast to his final design with softer lavender-blond hair, and brown-goldish eyes. This lost unused model appeared briefly in the Japanese version's Story Mode menu (alongside Umbreon) and promotional materials before being replaced late in development.
