The Mangle was a gender neutral animatronic made to be a more kid friendly foxy. But the kids constantly kept tearing him apart and the workers gave up on fixing her. Ever since 1987 and the whole “bite” incident, she was put on the wrong night more and kills any human he sees. She isn’t like the withered or springtrap, he’s programmed to do what he thinks he has to do. She climbs on walls using wires as a advantage since she can easily be broken apart again. They use male and female pronouns.
