She's the only female member of the team and transforms into a spider. Her character design pulls from Poisony, the villain from season one—same general vibe. In her human form, she's got short light purple-pink hair and wears a red office dress.
Her name comes from the Greek word for spider, "arachne." She's got this weird habit of dragging the girls down into the sewers to fight, though the show never really explains why that's her go-to move. Fans often note that her sewer episodes are some of the most memorable, even if they never quite make sense.
