Character Backstories.doc#
This document titled "Li-Po Character Backstories", often more widely known as "The Li-Po Backstory Document" or similar, has garnered some level of notoriety within the game's community and was one of the only files retained from the February 2013 leak of the game until the rest of the files were re-discovered.
Written by Tim Schafer and last edited in September 2002 (though dated as 2001 in the page footers), it contains writeups detailing prospective backstories for most of the characters in the game. That being said, the document stresses that most of the information is not at all intended to appear in-game (and likely isn't intended to be solid canon, either). Instead these writeups primarily existed to provide a point of reference for writing characters and dialogue in the game. Much of the information pertaining to major characters has been retconned or reworked by Psychonauts 2. That being said some of the information regarding non-returning characters does seem to somewhat hold up in Psychonauts 1. Boyd for instance has an elaborate backstory written here that is heavily referenced by many different aspects of his level, despite it being impossible to piece together the full picture or recognise the pieces without having read this document.
