Biffy would be "the Detentionaire," if he ever cared enough to sneak out. The detention room is kind of his base of operations, where he can spend his time maintaining his loner bad boy image and breaking into the school files. He's built like a fridge and feared by all, but if you spend enough time with him-like Lee has-you'll discover he has a soft side: a secret love for cats, zen meditation, and knitting. Biffy is Lee's co-pilot for sneaking out and getting back on time.
Lanky, eccentric, and good-hearted, Holger is the guy that makes Lee and Cam a tight little trio-or "friendship goofen-burger" as Holger might say. An exchange student from some European country that Lee and Cam have never heard of, Holger struggles with English, but usually gets his main points across: he likes unicorns with sideburns, tapioca pudding with grated ox tail on top, and "disco party times." Holger helps Lee on "missions" and uses alter egos when going undercover.
Lee Ping is that mysterious cool guy who seems to breeze through school. But he's no overachiever! And he certainly has no interest in being in any clique. He's his own guy and fiercely loyal to the same two friends he's had for years. All that changes, though, when he's framed for the biggest prank in high school history. Now he needs to apply all of his numerous mental and physical talents to fully navigate every aspect of school life and beyond as "the Detentionaire!"
General Barrage is a half cybernetic ex-military tyrant. He also happens to be the new principal. Saying he rules with an iron fist is not only true but quite literal (he has an iron fist). He hates vermin, dancing, kangaroo pie without ice cream, and most of all, Lee Ping (for trying to make a fool of him on his first day). His mechanical eye is always zooming around trying to catch Lee in the act. He also has an army of otherworldly Hazmat cleaners at his disposal.
Cam's a hustling, rapping combo of energetic fun and mucho bravado, and has been Lee Ping's best friend since they were ten years old. Cam's goal in life is to become "Big Hombre on Campus," and he's like a kid in a candy shop around all the "Chiquita-leaders" (Cam-speak for "cheerleaders"). Thanks to Lee's infamy as the prankster king, Cam can now take his quest to rule the school "to the ceiling maximus, yo!" And along the way, his social skills come in plenty handy for infiltrating school cliques for Lee's intense investigation.
A TV anchor for the A. Nigma High school news, Tina's a goody two-shoes, hard-hitting investigative journalist with a lean toward sticking up for student rights. She's also good at getting to the bottom of things. Tina and Lee have an unresolved crush, but are too shy to admit it. But the biggest scoop in school news right now is the prank, and investigating it may draw them ever closer.
