My favorite thing about making Portal OCs is that Aperture is so batshit crazy basically anything you base your OC off of would work.
“My OC is named Bessie and she was a robot designed out of 5000 knives and 2 traffic cones” and that would basically be a TOTALLY CANON CHARACTER THAT COULD WORK IN THE GAME
“I made a camera robot OC who’s only job is to make sure that the other employees aren’t eating Bob from Robotic’s lunch”
That would FUCKING WORK
