MHA and MLB crossover (title: a little bit of UA)

How it happend

Alix time travels/teleports from Miraculous Ladybug dimension to My Hero Academia dimension. She suddenly develops a cool quirk as her Miraculous merges into herself.

Now she has bunny traits and goes to UA her quirk is teleportation witch is not all that different from time travel. She can't go back to Miraculous dimension because she can't time travel no more. She dyes her hair green as well as her ears and tail. She changed her last name and has been in the MHA dimension for a year now.

What happens when the war comes around and she has to protect everyone?
