I was going to say the same for the power, mostly because its like a reset button; which would make things dull - a support type like a telepath would be great as most have said we have the blasters, we have the brawlers and we even have a tank of sorts (but not yet, his powers need to come out more lol)

EDIT ive managed to make a post for Jax and John, hopefully someone will try and help John keep the younger kids calm :D
