/lit/ - Literature

I'm writing a fantasy story where the MC becomes unreasonably strong and capable, and the whole story is basically him utterly and relentlessly dominating every facet of existence, up to the literal and unironical conquering of the universe and all existences.
It's not exactly a story with deep themes, I just want to explore this cool world that I created. How do I avoid my MC seeming like a blatant self-insert? He's not human, and at first I wanted to write a woman Mc but I realized women are so uninterested in the edge part of conquer, I couldn't write a convincing woman wanting to explore the universe and conquer is convincingly. It's the whole meme with girls with a time machine going all I'm your grand daughter.
