1, 9, 14, 16!!
1. Weapon of choice? I assume anything that gets the job done fast and quick. Any 'state of the art' weaponry. (I can kind of see him being a sniper-type of attacker and use whatever weapons they use for skillful, sly, quick killing...) I can't be specific since I have pretty amateur knowledge on weapons, but at least there's an idea of what he'd use.
9. Oh man, that's a tough decision. I would say he learned mostly on his own and from some experts, such as Koga, perhaps? lol idk, maybe Bruno, too. But since this is AU, I guess he could have also learned a lot of his moves from his grandfather or even from his father before he passed away.
14. He is calm upon getting captured; he is not intimidated easily. He devises a thorough game-plan and finds many ways to take advantage of his captors by any means necessary. He is quick at improvising if his original plan does not work.
16. ... That's a tough one! I haven't thought too hard on this. I would play some video-game music from games such as Skyrim or Call of Duty-- I don't play those-- when thinking of him fighting.
