The only thing that you CAN eat is people without the powers, people with the powers... And you can drink coffee... But that is all!
It's from an anime. I found it interesting to think of... because when the boy in the anime was given powers, he couldn't eat his favorite hamburger, or anything else. He always had to vomit from the food.
So the powers:
Rinkaku (Tentacle, tail like mutation)
Koukaku (One that works like a shoulder blade)

Oh man if I didn't have to eat I would be so happy. It would make my life so much easier. It would be like a super power in and of itself!1
