Quirk: Warp
She can make big and small warps. She can put her hand through one and make her hand come out another warp. An example is that if the opponent throws a knife at her she can make a warp in front of her and one behind the opponent so the knife will go in the warp and out the other to where it'll stab the opponent instead. Also imagine someone uses explosion quirk on her, she can make a warp in front of her and another warp somewhere far away. If she makes one warp she has to make another warp for the receiving end.
Evolving: When her quirk evolves she can then create beams that can be launched at an enemy and send them to a location she chooses.
Drawbacks: Extreme headaches, which is
why she takes pills with her at all times to ease the pain. The pain depends on how big the warp she makes and how many.
Backstory: She had a normal family and they were all happy until one day while they were at the mall it collapsed due to a big earthquake. Everything was chaos and her family were trapped under rubble, she tried getting them out being the only one who wasn't trapped but couldn't. Soon All Might came to save the day, he went to Mei and her family, when he did he looked up seeing that the place was about to fall down completely, he didn't know what to do since lifting the rubble off of Mei's family would only make the building fall faster. Her mother then told him to leave and take Mei with him, as much as he wanted to protest he had to do it. He took Mei in his arms and left quickly to get out as Mei screamed to not leave her family behind. All Might felt bad but had to keep going cause at that point the building was starting to fall. After being in safety Mei was crying heavily due to having witness what had happened, being so young she was taken in by a foster family but she never opened up to them and only grew distant. When she discovered her quirk she made many trips out to the cities and witnessed the many flaws of heroes. From there she trained and trained to make her quirk stronger for bigger warps, when she was ready she took down half an entire mall to make them not only feel the pain she felt but to test the heroes and their ability to save. From there she continued doing the same thing being able to escape quickly due to her quirk and running away from her foster home. She became known as Hametsu and was feared by many, after many years she had finally been caught by All Might of all people, for this she was ashamed but accepted defeat and went to tartarus until being forced to join UA.
Introduction: When she first arrived at UA the police brought her in handcuffs during the training Aizawa made the students do where someone would get "expelled". Apparently some people agreed that it would be a waste of talent to leave the girl in tartarus so they decided to try and bring her to the "good" side in UA. Of course leaving her in Aizawa's care due to his quirk.
Introduction to "villain" arc: At one point where she was moved to the dorms she was kidnapped by the League while she was in her dorm room alone. Having to agree to their terms she is forced to become a villain again for a short period of time.
