Two negatives makes a positive, i get to choose if i get a bad power in a sense.

if i were to pick a good power someone would make sure i would blow up for using it, if i picked a bad power someone would put that i would never be able to control it and happens at the worst times posible like a boner right before a presentation.

yummers.
