A man gets launched into medieval Britain into the body of Mordred, the Knight of Betrayal. He/She tries to change their destiny of being killed by their father.

Basically Harry has an older brother, who ends up with Hermione. And I don't own these characters except the few I may make up, the rights to them belong to J K Rowling, this is just a fan re-write. (Please don't remove story) @Raider0401 made this for the blurb: Away, away in Hogwarts, among the willows and pines, shying behind the puffy clouds, the soft sun shines. But something does seem off, the Potters have sons, not one but two, Yes, you are the eldest chosen one, and, wait, Hermione loves you. Dive into this amazing journey; see if you are worthy, to become Hermione's cherished loved one. In this incredible story of love, war, and mystery, you will have loads and loads of fun!

When six idiots are dropped into the world of smash brothers, shit hits the fan, there will be love, Drama, fighting and maybe a little bit of lemon.
