Boost is mostly a cheetah, maybe cross with a tuxedo cat or something? I call him a "Domesticated American Cheetah"
Personality. Boost acts like me when I've had far too much coffee; Hyper. For those that haven't met me, outgoing, a bit of a showoff, but without being too loud and obnoxious. Seem to make friends pretty easy, is friendly, can keep a cool head and very rarely gets angry, but when he does you'll know about it. Boost generally either avoids a conflict or submits if its not avoidable. Clever, lazy, loves a good bedflomp, or when drunk, floorflomp. Gay. Very much a logical thinker, not much an emotional thinker. Mechanic, loves making cars that shouldn't be fast go fast, and loves making fast cars faster.

This ref sheet is slightly out of date, boost has become a little less pointy and a little more hugable.
