- "I am the Obliteratrix, and I have but one purpose: to destroy Mystery Incorporated!"
- - Obliteratrix
Obliteratrix was the second disguise of Alice May. This time she was carrying out Mr. E's orders to make it look like the kids were in danger in order to draw out Professor Pericles; if he came to help them he might weaken his defenses on his piece of the Planispheric Disk.
She was wearing a high-tech black leather dominatrix-type of costume arranged in rings around her body. The mask has lenses over the eyes and a large metal part over the mouth which acts as a voice scrambler.
She showed high dedication in carrying out Mr. E's orders and when Angel Dynamite caught her she seemed to be very upset. Also an odd thing is that while she was explaining how she become the Obliteratrix she mentioned Professor Pericles with a clenched fist and an angry expression.
Powers and abilities
Her suit enhanced her agility allowing her to jump higher and farther and run faster as well. It also allowed her to become invisible at will, a technique she used to escape from a trap. The suit seemed to be fire retardant as the Obliteratrix could walk in fire with no signs of injury. According to Shaggy Rogers, her most bizarre ability is that the suit could generate weapons from nothing. She used a laser gun, a large compound bow with homing arrows, a large sling, throwing bombs, nets, a laser whip and a bo staff. In addition the Obliteratrix has a degree of knowledge about unarmed combat and acrobatics.
Scooby-Doo! Mystery Incorporated
As the Obliteratrix, Alice May managed to make the kids think they were pursued by an assasin. All the attacks were intended to be fake though the weapons were real. Her first attack, which seemed to destroy the Mystery Machine, actually blew up a copy instead. (Pawn Of Shadows)
- The flashback story where Alice May gets the weapons features a cameo by Dr. Quest, Johnny Quest, Race Bannon, Hadji, and Bandit from the original Johnny Quest series.
