Terminator
John's serious, focused and damned determined to win whatever war he happens to be in. He's more than willing to work with others and when given the chance can be quite the speaker.
Mainly allies at this point.
John is getting sick of this crap with Hypatia and the Resistance. He's thinking that maybe taking the war to them instead of trying to sit on the sidelines might be the best idea. That means he needs an army and that will involve working with the others. So expect to see more of him as he tries to make contact with the other soldierly types on the station.


Star Wars Republic Commando.
He's a textbook little brother. A textbook little brother who loves blowing stuff up! Pretty much that's it. He smarts off, then makes stuff explode. He's not a very deep individual and he really doesn't mind that.
Anything! He's a friendly guy, but he really needs to get dragged out of his tight little circle of interaction (i.e. his brother) and make some new friends.
Not at the moment. I really need to fix that.
