Neito Monoma ( Monoma Neito?), also known as Phantom Thief (ファントムシーフ Fantomu Shīfu?), is a student in Class 1-B at U.A. High School, training to become a Pro Hero.
Copy (コピー Kopī?): Neito's Quirk allows him to duplicate and use another Quirk after coming into contact with its user. He gains full access to the Quirk he has copied and can use it however he likes, and it is also possible for him to copy several Quirks at the same time. However, a drawback is that Neito cannot simultaneously use multiple Quirks, only one at a time, and can only use the Quirk he has copied for five minutes. After his time limit is up, he loses the use of the copied Quirk until he comes back in contact with its original user.  He also can't effectively copy Quirks that store power over time, like One For All and Rewind.
