I have a OC that's been bouncing around in my head for some time now. She's a weapon master with the ability to pull weapons from the people around her. The shape the weapon takes depends on the person in question. One person might provide her a bow, the other a sword and shield, the other a flail. 

It's a character that definitely involves a deep understanding of both weapons and weapon types, and cooperation with the other characters creators to decide what weapon is going to be pulled. So I haven't quite found a place to put her in so I haven't developed her much past this specific ability.
