All for one

All for one: All For One is a Quirk in My Hero Academia that allows the user to steal other people's Quirks by touching them. The stolen Quirks can then be used by the user or transferred to others. The user can also combine and modify the stolen Quirks, which can have devastating results. The user can give and take Quirks through a hole in the palm of their hand. The Quirk allows the user to wield multiple Quirks at once.
