I'll chime in:
1. MannDude, he runs the place afterall and probably knows some secret moves. Plus that gun+cat are frightening!
2. Monkburger, that dude is a ninja. Tech bad ass and probably has a hobby racing circuit cars on the weekend.
3. SeriesN, he's a Ninja and a Hawk and anyone surviving the NYC jungle has some slick moves.
4. Novacha, that undercover brother codes while sleeping. He'd probably bring a fleet of robots to play on his behalf.
5. Fran/Ald, frick and frack, the international connection. Even if we got whipped in competition, they'd make it pretty lighthearted. Secret pony powers or fermented apples? Are these really two people?
