Geochelone Aerios, also known as Aldabrans, are bipedal tortoise-like aliens from the planet Aldabra, in the Andromeda Galaxy.


Geochelone Aerios are green humanoid turtle-like aliens with 6 or 8 holes in their torsos. They have large, flipper-like arms, small stumpy legs, and pupil-less eyes.


Geochelone Aerios are non-violent, preferring to spend their time eating grass and debating philosophy with each other. They appear to enjoy gathering in groups.

Powers and AbilitiesEdit

Geochelone Aerios can blow powerful winds from the holes on their torso shell while also using their arms as propellers. This allows them to create winds and spins themselves at high speeds. Their appendages rotate with their shell, staying static and suspended when flying.

According to Dwayne McDuffie, a Geochelone Aerios' wind blasts are powerful enough to redirect objects.

Geochelone Aerios are immune to poisonous gases, courtesy of the holes on their shells.

Geochelone Aerios are immune to both an Anodite's Mana attacks and magic in general. In fact, according to McDuffie, Geochelone Aerios are capable of performing magic themselves.

Geochelone Aerios can use their blowing ability to make themselves fly like a helicopter.

Weaknesses Edit

If they get stuck to something and cannot spin their arms and legs, or if any the holes on their chests get blocked, a Geochelone Aerios' wind powers will decrease.

If a small object is jammed in a Geichelone Aerio's shell, it will irritate them enough to stop in order to remove the obstruction.

Geochelone Aerios can be affected by magic if they do not using their magic immunity.

Omnitrix Transformation Edit

The Omnitrix's Geochelone Aerio representative is named Terraspin, who first appeared in the Ultimate Alien episode "Reflected Glory". He was originally unlocked in "Escape From Aggregor" after the Ultimatrix scanned Galapagus. Terraspin solely appears in Ultimate Alien and Omniverse.

Terraspin is available in Mad Ben's Omnitrix, as glimpsed in the Omniverse episode "It's a Mad, Mad, Mad Ben World: Part 2".


Geochelone Aerio comes from "Geochelone", which is a genus of tortoises; and "Aerio", which is Latin for air.



  • According to McDuffie, some Geochelone Aerio philosophers have thought of lying, but they do not do it.
  • According to Duncan Rouleau, the Omnitrix from the Ben 10 reboot contains Geochelone Aerio DNA. Therefore, Terraspin is one of the countless aliens whose DNA pod was glimpsed in the episode "Innervasion Part 5: High Override".
