Multiverse: Transmigration

Disclaimer: It's a fanfic I don't own anything except my OC's etc,etc. It's just a wish fulfillment fanfic about our MC going to different fictional world's. First world: Marvel WARNING The MC is going to be OP from the start. There will also be a Harem(big one) and R18 scene's. This is my first time writing and English is my second language, so please go easy on me.
