Pepper belongs to the Three Girls Gang, focused on opposing Lum, Benten, and Oyuki. In the original series, she has long black hair and wears a teal armored top and pants, white gloves, a sky-blue headband, and leggings. The remake redesign depicts her with violet hair, a green anaconda-patterned top and pants, black gloves, a white headband, and leggings. Her primary ability allows her to shed her skin at will, similar to a snake, leaving the shed skin intact as a single piece while she remains fully clothed. This discarded skin can be worn by others as a suit, as demonstrated when Ataru attempts it, resulting in an unfavorable outcome for him.
