First generation. May is at first the cruelest of the Sisters, terrorizing humans with even less thought to their well-being than the others. However, when a shot from Mister beheads her and her still-working head is picked up by Angelica, May gives her information on where Mister is going in exchange for being returned to Marciano. Before she is retrieved, May turns to the side of good and helps Angelica and Chelsea. Her weapon, used once, is a Franchi SPAS-12.
