Toxica Terra’s costume is inspired by Paldean Wooper’s distinct coloration. She wears a sleek, dark brown and purple costume with bioluminescent patterns that mimic Wooper's skeletal markings. Her outfit is designed for mobility and protection, with reinforced gloves and boots for combat. Her mask includes a filtration system to protect against airborne toxins and features glowing eyes to enhance her vision in low-light environments. She also wears a utility belt with vials of antidotes and purification agents.
