Lacey Shadows is Baron Vain's favorite henchwoman and a criminal, and one of the personalities Agent Xero disguises as. Her first two appearances is in the drain, along with Rat, taking away "The All-Seeing Eye".
In this form, she has teal hair with purple hightlights and wears a black frilly dress with a lavender shirt under, black fingerless gloves, cyan buttons on it and a teal belt with a cyan buckle, black high-heeled boots and purple leggings with stripes on it.
Lacey's personality is different from that of her original. She is very sneaky and clever whenever Xero disguised as her to foil Baron Vain's evil schemes. She is somewhat athletic, tough, and sarcastic. Unlike Xero, she is really tomboyish and loves to mess with Rat at any oppurtunity. She is also not much of a team player, noting that while she and Rat both were on the same team, "and I'm the team captain ."
