The poison lizard sisters, Raptora and Reptera. Members of the fearsome Monsters Association, both of them are former humans turned into scantily clad and voluptuous reptilian women with wild manes of hair, horns, scales across their bodies and large tails and able to control poison. 

Raptora is the youngest, and wears a two piece bikini, gloves and boots. She wields a machete

Reptera is the older one, with an even more skimpier attire of nets, straps, and bracers on her limbs, and no top.
