Walkatrout is a small, blue fish-like alien, roughly the same height as Upchuck. He has stubby fins for arms, a shark-like dorsal fin, and a pair of thin, spindly legs jutting from his underside. He has a wide mouth with an underbite, and gills on his cheeks. He has bulging green eyes.
Walkatrout wears a green belt-like strap around his "waist" and back, with the Omnitrix symbol connecting the front.
