I just posted about my shiny new Echo, but I also have two Alphas who live on the same floor as this guy!
Blitz smoothasglass is damage #3 for Alpha, tries not to take much seriously, and hates being cooped up. He's a speedster who can convert his own kinetic energy into concussive blasts, and he works best and rooms with his big brother, Backlash (Alpha tank #1).
Leah steelyeyed is Alpha handler #1. Kinda bossy, doesn't take shit, a little bit sadistic and has the tendency to push her supers farther than they should probably go. (Like injuring one of her tanks so the healer can/has to practice.) Cold blooded and thinks of supers as weapons more than people. Areas wouldn't have to deal with her much, though, since she's part of a different team!
