Ivy XO is the current leader of the Engineers faction of the wasteland. She has two feathers in her hair, often in a side braided ponytail, black sclera with glowing yellow irises, and some sort of mask over her mouth, presumably a breathing mask for the wasteland air. She also has tattoos on her left arm and carries a huge red wrench. She wears a gray tanktop, black fingerless gloves, black pants, and boots. She was born shortly before the disaster in the family of an auto mechanic.
