A mutant whose strength runs on adrenaline, which means the angrier the fight gets, the worse it goes for the other side.
Angel Dust is a mutant with adrenaline-based strength and durability, a member of the Workshop working under Ajax. Gina Carano plays her in Deadpool, and the film gives her the fight it cannot give Wade: while Deadpool goes after Ajax, she and Colossus take each other apart on the carrier, and when it starts to collapse he saves her from it. The reader who sent this list summarised her as the assistant to Ajax who fights Colossus, which is the whole of her part and a fair account of it.
