Marvel: I Evolved Into Superman on My Own

Shen Fei transmigrates into the Marvel Universe and becomes a member of a Hydra research institute.

He gains the talent of a master scientist, allowing him to perceive and understand all knowledge and truths.

His body possesses the power of an evolutionary spirit, letting him absorb anything to strengthen himself!

From the start, he develops the Super Soldier Serum, and that is only the beginning.

He studies different superhumans to learn their abilities, then combines them organically within himself.

I will use science to bring the God of Man, Superman, back to the Marvel Universe!

Wolverine's healing factor?

Wolverine, I've already dissected you anyway. One more time won't hurt!

Super strength? Hulk, don't go!

An iron body? Heat vision? Getting stronger by absorbing sunlight? X-Men, hold it right there!

Finally, holding the Infinity Stones, Shen Fei looked at Thanos and said with a smile, "I'm very interested in you Eternals!"

(For the sake of the story, this does not follow the Marvel timeline exactly. You know how messy Marvel's own timeline is.)
