Everybody hates Alex, despite the fact that he has never really done anything to deserve it. Poor guy. He and Colin are close. Perhaps too close.
Brogan
Brogan hates everybody, especially Alex. He does have a soft side, though, somewhere, deep down. Very deep down.
Colin
Colin likes to be creative, even when the things he's creating aren't so good. He's easily excited and persuaded.
Harrison
Harrison tries to make friends with everybody. He's even kind of okay with Alex. He's very obsessive and occasionally paranoid. He and Jori are good friends.
Jori
Jori's kind of hard to figure out. He seems to have magic, world-altering powers and operates with a bizarre logic. He can be quite aloof.
Pat
Pat is so dumb, it's ridiculous. He once failed a class he wasn't even in. Despite his low intelligence, however, he has the biggest heart of everyone.
The Ahh Guy
The Ahh Guy is hidden in one hard-to-see spot in every episode. He is an enigma, silently screaming for all his days. Try to find him in every one!
Tom the Bus
Tom is a kindly neighborhood man that happens to have a genetic disorder that makes him look like a school bus. He's normal besides that, though. Don't make fun.
Mr. Dooheney
Mr. Dooheeney teaches... something at Sumwhere High School. His lectures contain confusing speech patterns and motives. His past is a thickly congealed mystery.
Memorizo
Memorizo, as her students call her, teaches Spanish at Sumwhere High School. She believes that the best way for students to learn is to memorize dictionaries.
Mr. Stweets
Mr. Stweets teaches gym at Sumwhere High School. He could be the thinnest, weakest and nerdiest gym teacher the world has ever seen.
Cool Platypus
Cool Platypus is a bipedal, probably mutated monotreme that wears sunglasses. He makes a point of always looking cool, but there just might be more to him than that...
The Diotic Ragabash
The Diotic Ragabash is a hapless supervillain. He may or may not be Colin's alter ego. He's also not Dr. Horrible. He is the only resident of Sumwhere to have a Facebook profile.
Sarah
Sarah is an ice queen, hiding inside an igloo of hate. She has a very low tolerance of stupidity, which makes Pat's crush on her even harder to handle.
