So... slippery!

Walkatrout[2] is the Omnitrix's DNA sample of a Ickthyperambuloid[DJW 1] from the planet Gilli-Perambulous Promenade.[DJW 2]


Walkatrout is a small, blue fish-like alien with 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 with bulging green eyes.

Walkatrout wears a green belt-like strap around his "waist" and back, with the Omnitrix symbol connecting the front.

Powers and Abilities[]

Walkatrout has a slippery body, making him hard to grab[3][1] and allowing him to slide on the Plumber HQ floor.[4]

Walkatrout has gills and can breathe underwater.[2]

Walkatrout has a degree of enhanced durability, as is shown when he was knocked onto the ground along with Speedyquick without serious damage.[1]

Although his body is quite weak, his tail is somewhat strong, as he was able to hurt Liam's Vaxasaurian form with it and escape.[4]

Walkatrout is somewhat acrobatic, as he can perform cartwheels.[4]

Being an Ickthyperambuloid, a Vladat's Corrupturas would not stick to Walkatrout due to his slippery skin.[DJW 3]


Walkatrout is physically very weak, being unable to break through a museum's doors[5] and he is not suited for hand-to-hand combat. He also has no hands, which makes grabbing things impossible for him.

It is implied that Walkatrout is not very fast, as Ben was disappointed transforming into him when he was trying to run away.[6]

Walkatrout is very small, giving him a disadvantage against larger opponents. He is only as tall as a Vaxasaurian's foot.[4] Despite this, Walkatrout is still unable to fit into cramped spaces such as toilets without assistance.[2]

While Walkatrout's slippery body can be used well as a strength, it also prevents him from being held up by his teammates,[1] unless he were to be held up by his tail.[4]

Being an Ickthyperambuloid, Walkatrout is vulnerable to his natural predator.[DJW 4]
