So, I was an author called Groft45 and did stories called Return to Gravity Falls and Gravity Falls: Return of the Weird. So, I recommend you read those first before moving on to this

It might get a little weird...It might a little wild...but DAMN if it ain't gonna be epic! One magical kid, a multiverse of possibility...What could possibly go wrong? (We're going so AU, it ain't even funny!) Rated M for later scenes.

This is basically Star vs the forces of evil exept Marco is the main character and has the Omnitrix and he also has a harem but completely oblivious to it like classic harem animes
