Invisible powers? What are those, exactly? Powers no one can see? Like, I can shoot flames from my nipples but they're invisible flames? And since they're PLURAL, does that mean I get multiple invisible powers? Maybe my other power will be to glow brighter than the sun and blind people…only it will be INVISIBLE and therefore useless.

I think you mean the power of invisibility. I guess that would be okay. It's no flaming nipples, though.
