Y/n L/n is A Young Man who is a Fan of the Super Mario games, but mostly of Bowser, whose powers and his love for his found family make him very likeable in his eyes, and then he died, though he gets reincarnated with the powers of Bowser in A New Body!

A normal guy from our world reincarnates as Jaune Arc before RWBY's first season, awakening a Creation Semblance that lets him creat powerful tech and magical items using Dust or Aura. Determined to create a better world for humans and faunus, his inventions [drawn from games, anime, comics, and more] start turning Remnant upside down. But what he didn't expect? Some female members of the original cast quietly forming a harem behind his back. Due to popular demand, this story is a harem, RWBY P, to be precise.

All he wanted was to be a hero a shining knight like his ancestors before him. Now that's impossible no team, no family, no friends, no future. All he has now is to wait for the darkness to consume him, but from that darkness a new knight shall rise!!! RIP Kevin Conroy/Batman

You died and God said you will be sent to the RWBY world as Jaune Arc. With your knowledge of the future events and fighting styles from other worlds you will rise and become the strongest huntsman. And maybe make the show good. Inspiration from The Ultimate Faker.

You died and God Reincarnated you as Izuku Midoriya. With your knowledge of what's to come and the use of fighting styles from other animes, you will be the best hero you can be and the strongest one there is.
