@Jones Sparrow: When you say ability, what do you mean? Does it have to be a combat skill or can we have a superpower in addition to the suit? I was thinking of something along the lines of precognition (limited to 30 seconds into the future) or line-of-sight telepathy.

EDIT: If all characters are baseline humans, that's good too. I just want to know exactly what I have to work with before posting a CS.
