My idea for the bone character. 
A very tortured soul, has resented his ability since he got them towards the forefront of the conduit outbreak. He resents it because it still hurts when he breaks the bones he manipulates, it hurts when they slice through his skin. He looked at it more as a curse than anything, not being able to control it, feeling the pain of his skeleton constantly shifting and cutting under his skin.
He would for the first couple years, not do anything with his powers, nothing other than attempt to slow the shifting of his own skeleton to dull the pain. He look at other people resentfuly, lucky they didn't have to deal with this as he did. As soon as the DUP and Curdon Cay were public knowledge he admitted himself in hopes that he could stop the pain and the hate. But he was very wrong, Curdon Cay was no rehabilitation center, it was a prison and a laboratory.

For a very long time the tested his powers, his physical and mental limits. They made him do terrible things to other test subjects. He killed alot of people. He just continued to grow more resentful, but less at his abilities and more at those around him. The normals whose lives were never touched by these abilities, the DUP for twisting and ruining who he used to be, and the other conduits who had gifts, not curses.


I wanted bone specifically because its hard to manage as a power. He would stick to primarily melee fighting, and guerrilla tactics(One skill i thought of was literally turning people into bombs of bone shrapnel)
Its likely he would try and find refuge with the Reapers, possibly taking up a offer from Cruor to set up a better 'power bank' for the both of them.
