We don't have a tank type yet, so he would be very welcome. My agent here would be especially wary of him because of his past, especially depending on whatever crime he committed to land in jail before becoming a super. How does kinetic superhuman strength and durability work? Is it something like the more he moves, the stronger and more durable he becomes? And would your character have been in the program for a while, or would he be a recent transfer? We can work with it either way. :)
I also have roguecharm who generally flirts with anyone, though might tread carefully around your guy until he's gotten to know him better. It's not actual interest so much as playing around, when it comes to males. He, too, wants his freedom, and he hates being stuck indoors. Some of that has to do with one of his powers, super speed.
