He could have the powers of Quiet from Metal Gear Solid V. he could receive it after coming into contact with space stone like wanda, who unlocked her powers after coming into contact with mind stone.
just give him, Reactive Evolution and Adaptive Resurrection and Assimilative Evolution. It's not over powered, you have to work hard to gain power's, and you can't be killed and what killed you makes you stronger
A simple human who uses his wit to defeat his enemies could be interesting but also some god giving him powers could be interesting like Moon Knight.
Example could be Yamraj giving him some power related to death which makes him able to kill any being with some effort.
this one is okay you can give him power of space while removing tesserect it will be logical and op and you can give h captain Marvel powers as she also got it from tesserect. And please update fast I have high expectation of this novel
Just give him a strength level similar to Captain America. It would be interesting. He could also be the MCU's Wolwerine. Including God's powers at this point in history seems so uninteresting.
