Alien Species

Ickthyperambuloids are a fish-like alien species from the planet Gilli-Perambulous Promenade.[1]



Ickthyperambuloids are fish-like aliens with stubby fin-like arms, shark-like dorsal fins, and a pair of thin, spindly legs jutting from their underside. They have wide mouths with an underbite and gills on their cheeks. Their eyes are either small or large and come in different colors such as white, green, red, or yellow. Certain Ickthyperambuloids can have irises, which are either purple or black.

Although they traditionally have blue skin, Ickthyperambuloids can come in other colors. For example, Negative Walkatrout has pale blue skin.


Ickthyperambuloids can live for at least 85 years.[1]


Ickthyperambuloids are preyed on by an unnamed trapdoor spider-like species. To their predator, they taste like Dolphins.[1]

Ickthyperambuloids are piscivorous, meaning that they eat fish.[1]

Powers and abilities[]

Ickthyperambuloids have a slippery body, making it hard for enemies to capture them. Their skin also makes a Vladat's Corrupturas unable to stick to them.[1]

Much like Earth fish, Ickthypermabuloids can breathe underwater.

Ickthyperambuloids have a degree of enhanced durability and agility. Despite lacking fingers, they possess a degree of enhanced dexterity.

Although their bodies are quite weak, an Ickthyperambuloid's tail is somewhat strong.


Ickthypermabuloids do not appear to be built for combat due to their small size.

Tecknically speaking, Ickthypermabuloids are physically weak and slow compared to most other species.

Culture and society[]

The Ickthypermabuloids are led by Arch-King Agillies Torondon Maguro, the mere figurehead of a waning, historical, and constitutional monarchy who walks pretty briskly. Despite it now being powerless, the monarchy is still being maintained and is beloved by both the people and the media.[1]

The Ickthyperambuloids' government is a terrible glacially slow-moving bureaucracy with endless amounts of middle management and wide-reaching amoral corporate influence.[1]

Most Ickthyperambuloids only wear spats as they like to feel the pavement on their flippers.[1] However, a select few wear white jumpsuits with collars covering all but their faces and dorsal fins.

Notable members[]

  • Walkatrout: An Omnitrix transformation used by Ben Tennyson
  • Gil Steptoe: A Ickthyperambuloid civilian and accountant living in Undertown.
  • Arch-King Agillies Torondon Maguro: The leader of the Ickthypermabuloids, who is affectionately and publicly referred to as "King Gilli".[1]



  • Albedo cannot transform into Walkatrout because he does not have access to Ickthyperambuloid DNA.[1]
  • "Walkatrout" is an inoffensive slang term that is used by other beings to call this species.[1]
  • Ickthyperambuloids would make great tour guides.[1]
  • In 2020, Derrick J. Wyatt released a full-color model of a hypothetical alternate version of Walkatrout used by Albedo.
  • Before making their debut in the reboot series, it was confirmed that the Omnitrix from the Ben 10 reboot contains Ickthyperambuloid DNA.[2] Therefore, Walkatrout is one of the countless aliens whose DNA pod was glimpsed in the episode "Innervasion Part 5: High Override".
    • This has been supported by the appearances of some Ickthyperambuloids in the film Ben 10 Versus the Universe.
