As far as powers, I always want to do something I haven't rolled before.  Knee jerk is Electrokinesis, but I've got to figure out a way to make sure that doesn't get bland.  I' been leaning heavily toward more obscure and less traditional powers lately, which I may end up doing for this RP, too.

[i]Umbrella Academy[/i] was a good example of slightly different powersets. Maybe I'll try to take inspiration from that.
