Hybrid in the hybrid universe (HPxMarvel)

Klaus always wanted to travel to a magical world, and experience how it feels to be able to use magic and have superpowers. When he wakes up in what looks like his old room,and is given chance to do just that. Only price is that he must make sure that his new world isn't destroyed by humans, mutants, wizards, crazy aliens and many others. While he is at it he should probably do something about all those animals that are going extinct, and that ice that is melting. What is newly created Hybrid to do,but give it his all. ----‐------‐---------------------------------------------------------------------- Mc is tasked with keeping Earth from being destroyed by humans,but at the same time he must let humans prosper,explore and be free. The story will concentrate a lot on magic and how it works while mc lives through human history. (Marvel × Harry Potter)and there might be some elements from DC. This is my first time writing, so constructive criticism is welcome. I am trying to get better at grammar as well as story writing. I noticed that everyone does this so I am going to do it too. I don't own anything except mc and some original characters this is a fanfiction everything else is owned by companies that own them. (Cover isn't my creation, and if the creator wants it removed please contact me.)
