[@Sophrus] The first thing that jumps out at me is that I would like to see more details on the powers and how they work. This is a world where powers work in a specific way most of the time, so if you can expand that then that'd be great. If not, then it's fine as is, but for instance the bone morphing. It has to be dead bone, ok cool, so when he morphs it, does this adhere to conservation of mass? If so, that means expanding it is losing density and therefore strength. If it ignores conservation of mass then that means he's somehow creating more bone material and if that's the case then what are his upper limits on something like that? Same with his zombies. Is there a limit to how many he can raise and control at a time? Does his concentration suffer the more he has? Etc. Details are vital.

For classification, remove shifter. His powers don't shapeshift his own body in any way. Separate Striker and Master as they're separate powers altogether and slashes are used to indicate when a power is more than one at a time. (He has two distinct types of powers, Striker and Master. If he raised zombies by touching them, then he'd be Striker/Master but since zombifying corpses is at range it's Striker and Master, separate).

Reading through his history, I'd like you to justify how his trigger manifested his powers. Striker class manifests from a threat that's in your face (natch, getting beat up) but Master class manifests from feelings of isolation or alienation. Did he feel like the world was out to get him because of his cancer? I'd like you to define that a bit better, as I'm not entirely seeing it from a basic readthrough.

You also mention in the history being able to "sense" dead bodies but this isn't listed anywhere in the powers. That'd also make him a low grade Thinker. You should remove that from history entirely, or add that to his power list (meaning he'd be a Striker and a Master/Thinker).

You say he is a Case 53 as well. This literally cannot be true. The information post states plainly that Case 53's are failed experiments from Cauldron. A natural trigger event will never cause a physical mutation and none of them can be called a Case 53. I'm perfectly ok with the trigger event halting, or even curing, his cancer, but he's not a Case 53 by any definition. 

Lastly, please do some proof reading. This form is rife with plenty of grammatical and capitalization errors, making it very difficult to read through.
