The only canon ability Shark is aware of is super-hearing. (Able to hear conversation taking place outside, while standing in a crowded and noisy gymnasium and over the sound of car engines outside. Could hear a heartbeat in a quiet room.) And she doesn't remember much of home yet, but she is hoping for a regular boring student life with some level-headed friends and rich parents. The kind of life she can be comfortable in.

As for Talon nothing is coming to mind right now, but I will let you know if I think of anything during the week! It would definitely be fun to play him with some kinda power though.
