Prophet has a fairly complicated backstory that involves being a Delta Force Operator, getting infected by a Ceph super-virus and committing suicide, a Marine (callsign Alcatraz) getting eaten by Prophet's Nanosuit 2.0 and Alcatraz having his personality overwritten by Prophets.
Then later stopping an alien "invasion" of Earth.
In terms of capabilities Prophet is best described as "post-human" as he doesn't have much in the way of fancy powers and is just more capable than real world humans in every single category you can think of.
