Primary: I have perfect control over my body, both the way it sounds and through a form of telekinesis. This ability even affects parts of my body that are no longer attached to me. This gives me limited shapeshifting abilities, super healing (which makes this a Prime Invincibility), flight, the ability to push my body to superhuman levels (strength, speed, etc), and the ability to, say, grow bone spikes from my body and stab everyone. It's really messed up.
Secondary: I can breathe when I shouldn't be able to, just in case my healing can't cover that.
Weakness: Jump scares. But only if I'm not expecting it.
Name: Flesh and Blood (because my skeleton is busy killing people, get it?)
Evil: I have a few copies of my skeleton lying around, and I tend to have them go on rampages in the more... rebellious parts of my city.
Costume: Whenever I go out, I grow bone armor all over my body, with a sword to go with it.
