It looks like you'll be making him Alpha tank #2! In that case, Leah would like to welcome him to hell, because that's kind of what her training is. He can heal? She'll make sure he gets practice with that. Just ask Backlash. She might even tell them to spar together. Alpha's losing their current healer to Romeo, so his self-healing will really be put to the test. She miiight have some sadistic tendencies there. Sorry?
Blitz smoothasglass is Alpha damage #1, rooms with his brother (Backlash), and is generally a chill guy. Not a fan of relationships because his ex-girlfriend turned him in, and he's only interested in ladies, but he'd probably flirt back with Onslaught just for shits and giggles. That's his motivation for a lot of the things he says and does.
Reaper thereaper is my Foxtrot and queen of the dead heads the morgue. She's got the power to reanimate corpses, and she loves it. Helena's kind of a sociopath herself, but she works very hard to hide it and the thoughts she has about wanting to dissect her fellow Ghosts to explore their anatomy. Very friendly on the outside, creepier than she lets on inside, and very interested in Who, the guy who killed her last handler in order to join the program.
Medic needamedic is my grumpy old miser who's been in the program just about forever. Expect a lot of eye rolling, especially if you decide to make Onslaught new. They live on the same floor, so they'll see each other around. He's not a fan of the Corps but he does his job anyway, because he can't stand the thought of someone dying because he failed to act, but he doesn't like anyone seeing his soft, gushy center. Very much recruited against his will.
And Livewire superconductive is my Juliet. Unstable, super flirty, killed a key witness in her ex-boyfriend's murder investigation and might have gotten the death penalty for it, but they decided to just lock her away for the rest of her life instead (I think, still working out her details). Kind of easily manipulated, but also violent when she's mad, and loves the chance to go out and fry people on missions, so watch out~
