It would be much better with a fluid animation, but the only way to do that would have been to use Deadpool as a base, which gets into all sorts of complications with his wings. I'd rather he look like a nancyboy than screw everything else up. Basically, the move has 3 animations- start, loop, and end, which Angel doesn't really have built into his anim set...his spin is all one animation. So it was either that, or scrap the power. I'm not in love with the power anyway though, so if people think it's silly enough, I have no problem scrapping it.
The HUD....yeah. Since the default XML2 costume isn't really a real comic costume, I just went with cool looking, rather than accurate. I will likely end up tweaking up another Angel costume at some point, with a more appropriate HUD.
As for the flying...did you start a brand new game? I know that characters often won't fly unless a new game is started.
EDIT: The X-Voice.whatever should be placed as archa_v.whatever under the same file as archa_m.whatever. so sounds/eng/a/r
