I'd have to say Patrick82, because he's probably a serial killer.
I know nobody cares, but here's why I went with our good friend Patrick.
Connie Marshall is now on Social Security due to mental illness, but has actually held a job and had a family.
Dozerfleet is an autistic person with an unfortunate conservative religious upbringing.

Basil Marceaux is just fucking stupid.
The time-traveling wizard apprentice guy might be a character, a fiction writer, or a guy who has very vivid lucid dreams, but doesn't realize that he's dreaming.
I'd need more info about the guy with the stargate in the school basement before I could say one way or the other.
John Kitchin is funny on the surface, but also very sad to me. It seems like he was probably born with mental illness, and abused as a kid, then left without any proper care, leaving him the disturbed man he is, today.
