Question:

I'm writing a book, with powers. Ideas?

I need power ideas so far I have: Fire, water, wind, earth, strength, speed, and invisibility. I would prefer, two more self help powers and one more attack power.

Best Answer - Chosen by Asker: Attack power: Power to posses any living object. That would be really cool. Self Help power: 1. Power to be able to make any plant of tree grow. 2. Power to control his own bones (reason its self help is because that guy can create an inner layer of thick bone under or over skin)
