I have a stupid idea for this dude's backstory/creepypasta/whatever:

"This is a version of Pico who went insane from his games and flashes being repeated endlessly, which eventually caused Pico to snap due to his trauma and having to go through both himself and the people around him dying. Because of this, he killed every Pico-related character (from Darnell and Nene, to Otis, to Samurai Asshole, to BF and GF, and eventually to even Piconjo), keeping their remains with him so they can "be with him" them for all of eternity. There were some characters that were powerful enough to almost kill him (such as Convict or the penilians), and others went down in seconds (such as Gibbons or Pico's teachers and classmates), but what is clear is that everyone who decided to fight back or run away were eventually murdered."

(ik this is edgy af)
