Blitzø is quite tall for his species, and sports a harlequin-like aesthetic. He has crimson skin with white blotches (later revealed to be scars from the fire he accidentally created while still at the circus) of various sizes that cover parts of his forearms, chest, and his tail, as well as most of the right side of his face. He has black spines on his head and upper back, as well as on his tail, which ends with a triangular point that has a black spot at the tip.
