5 Years later Wiki

Astronaught is the Omnitrix's DNA sample of an Unknown species known as “Squirmers” from an Unknown planet in 5 Years Later.

This transformation was a commission and not valid for use by other projects outside of the 5YL Wiki without permission from the original creator.


Astronaught is a small transformation with a pink segmented body composed of many rings like an earthworm. He wears an advanced green, black, and white armor with a visor. There are several “panels” on the armor that can open up and revel mechanical limbs with various equipment.

The Omnitrix symbol is located on his anterior near his visor.


  • Enhanced Creativity- Astronaught has an overactive imagination, allowing him to come up with unique creations and solve difficult problems by thinking outside of the box.


  • Armor- The Omnitrix is able to replicate the Squirmer's armor and power source, creating a variant that is less clunky and more suited for mobility and combat. This armor allows Astronaught to move, fly, and create hard-light constructs out of virtually anything he can imagine.
    • Rechargeable Power Supply- His constructs are “recyclable”, meaning once it serves its purpose, the energy returns into the suit to help provide power. The armor can also receive solar energy and convert it into power if necessary.


  • Frail Body- Although he has above average mental capabilities, he lacks much physical strength and can be harmed very easily.
  • Overactive Imagination- His immense creativity, can also be a potential weakness, as he can end up thinking of absurd hypothetical situations.


The “Squirmers” were a species at an evolutionary dead-end, being physically useless and unable to even conserve their own history due to their lack of writing and their overactive imaginations, leading to many different tales of their past. These aliens were left to die by nearby species, until an unknown entity all “Squirmers” refer to as “The Caretaker”, a mysterious individual who gave this species a second chance at life. The Caretaker provided them with basic suits of armor neurologically linked to their host. While the workmanship of the armor is relatively shoddy, all armors possess an unknown generator that allows the “Squirmers” to create tools and weapons out of hard-light constructs. Using the armors, the “Squirmers” find themselves working as helpers for other civilizations, who support their creative drive.

While somewhat bitter about being left to die by the other species, the “Squirmers” continue to make effort in putting their past behind them and follow in the footsteps of the one who gave them a new life.






  • The Squirmers are a recently discovered species and have no official name yet because they do not recall what they called themselves.
  • Astronaught's name is a mix of the words “astronaut” and “dreadnought”, a reference to his space suit and his abilities to form tools and weapons for combat.
