Overall, seems mostly fine. The only things I could mention would be a clarification to his Power and a change to the end of his Background. After 'seem invisible' I would add 'if looked at from the front', since he's just flat rather than gone if I remember correctly. Lastly, the thing that brought everyone to the World of Light was less a subtle dimension shift and more a universal annihilation attack. Other than that, the sheet's okay.
