Marvel: Time Warper

Ky Thatcher was born as a mutant in a world where mutants are seen as scum beneath humans. Once the X-Gene was discovered, showing what mutants were capable of, humans started doing everything they could to keep themselves safe.

They took them away from their families, shoved them in camps, and murdered mutants like cattle after developing ways to subdue and kill them. The ones who couldn't be killed were forced to suffer fates worse than death...

For eight years, those who survived went into hiding. However, things would soon change once the mutants began fighting back.

Ky is not OP from the jump, he gets strong over time. You will see. As you can imagine, warping time will get pretty broken.

This also takes place in my own Marvel AU, not the MCU.
