I found Alpha Bravo's somewhat amusing. I'd always contended that he was an idiotic choice, because he'd -never- be able to keep up. Sure not every member can break the sound barrier, but at least they move faster than they could walk.
Being the "new guy" and the slowest of the flying group makes him feel like he's got something to prove.
I'm hoping that in the comics he either a) dies rather quickly, and Quickslinger steps up to replace him or b) gets booted off the team, and forms part of another gestalt team. Say.... Galvatronus!
On the lookout for MISB Headmaster Highbrow, Takara or Hasbro. I'm sure I could make you a sweet deal!
