superman in marvel as peter's brother

Nope, Superman isn't a Marvel comic. He's a key figure in the DC Comics world. DC has its own unique style and set of characters, and Superman is a big part of that.

Superman could fit into the Marvel Universe in several ways in fanfiction. Firstly, his origin could be tweaked a bit. He could be an experiment gone wrong in a Stark Industries lab that gave him his powers. This would immediately connect him to the Marvel world. His powers would still be his trademark ones like flight, super strength, etc. He could then become a sort of protector of a particular city in the Marvel Universe, like New York. He would interact with the local heroes and villains. His presence would disrupt the power balance a bit, and some villains might target him specifically. But with his unwavering moral compass, he would stand up to them and become an important part of the Marvel Universe's tapestry of heroes.

With just a slight flap of his wings, he passed through the nine heavens. He could feel that the gravity of the planet could no longer restrain him until he reached deep space. His long black hair danced in the starry sky without any wind. His scarlet eyes stared at the deep-space mecha that was flying across the starry sky at high speed. He laughed maniacally and muttered in a low voice,"Ha, hahaha... Now... Now it's time for you to know my tolerance!"
