[@Lord Wraith] Both of the character ideas I most want to play aren't exactly combat oriented. Although both could be put to some use, and one could be used to stop fighting... Umm, I'll just give you the rundown, shall I?

My preferred ability would be basic psychometry, being able to hear/feel/taste/smell/sense the past as it's been recorded by objects around the character. He wouldn't be able to turn it off, so coherency would be dependent on his ability to separate his thoughts and any conversation around him from things he's hearing and picking up at the time. This means that if he's scared or in a tumultous area, it'd be harder for him to make sense. So, he'd not be very useful in a straight up fight. Nor do I expect that this character would like learning self-defense techniques or weapons... But I suppose he could be useful before a fight if people are trying to be sneaky, since with enough focus he would be able to tell if peopleare nearby from their clothes, and/or weapons. So, straight fighting, he'd be no use, but in other combat tactics, getting in and out or following people or something, he might manage.

The second choice is the absorption of chemical energy. ATP, basically. This character would be a little more capable of defending himself if he has to, though I still wouldn't plan on him having a lot of ability as concerns fighting. And he'd be a liability in any situation where people other than the group he's working with aren't around, as he tends to need a constant low energy supply from others if he's being too active. But he could very easily just drain people beyond the capacity to move if they're close enough, which could definitely come in handy.
