Ella potter and the avengers

This story is a Marvel x Harry Potter story. When Ella potter comes to find the avengers she finds the avengers fighting Thanos and decides to help them kill Thanos for exchange for the avengers to help kill Lord Voldemort.

Please don't judge the story I wrote it a long time when I was watching Harry Potter not any of the Avenger movies.

All characters except Ella potter/sapphire go to J.K Rolling and Marvel
