Nick, I just read your post, and it made my day. PLOT Device. :D
My question: Who is uncut?
Character powers... As long as they aren't damaging to the story or blatantly OP.
Vrach is a supersoldier, basically. It's what he does. That's ALL he does. He can't even socially interact properly half the time.
Nick- I trust to do the the right thing for the story, since your character is pretty much an unknown entity.
Most people have a mix of skills but have their thing that they excel in. Works
