As promised, here's two of Jinx's planned three (didn't have time to finish Shortcut but he's got a Josh Hutcherson face so watch out, world).
This one here is Selena Espinoza, AKA Gunslinger. She is brand spanking new to Limbo, just transferring in from West Texas. She's friendly, flirty, forgetful of names, and also a former criminal. She got busted during the aftermath of a weapons deal gone bad. It didn't end pretty for the other guys. Her powers are centered around weapon manipulation, which means she can do fun things like a less extreme Mami Tomoe from Madoka, or like Loki and Hela whipping out their weapons, or that scene from X-Men where the guns all get turned on the cops. Because it's cool. She's on Sangha's unit.
Then I have Asa Miles/Maverick inahurry. He's an asshole. His name amuses me because he's an Asahole who can go for Miles. I'm a dork, moving on. He's been at Limbo a little longer than Selena. How long? Idk I forgot to specify. We'll just vaguely leave it at "a while." He's been in the Regiment since '08, but probably not that long at Washington State. Oh, and he's a speedster, and the reason he got caught is because he couldn't help himself and joined the school's track team like first thing. He's on Marshall's unit.
