Stephon Walker is Swami YoMahmi

Mab (Just Mab)

Self-proclaimed monkey lover, freak, sideshow girl, and musician, Mab is an artful glass walker, escape artist, fire eater, and drummer, full of boundless energy and humor. Mab believes that every single person has superpowers. One of Mab's super powers is the ability to find the shortest lane at a toll booth.
The other is the ability to walk on broken glass and hammer spikes into her face. Mab is a freak. You probably shouldn't try that at home.
