Terraspin

Terraspin is the Codon Stream's DNA sample of a Geochelone Aerio from the planet Aldabra.

Appearance
Terraspin is a green turtle-like alien with eight holes in his shell. He also has large, flipper-like arms and stumpy legs. He also has retractable claws to use as fingers.

Terraspin wears the Ultimatrix/Omnitrix symbol on his chest.

In Omniverse, Terraspin now has six holes instead of eight, has spots on his upper legs,toes and shoulders, and has a hectagonal body shape rather than circular. His skin is now green instead of a tan/brown. His feet have gained toes as well.

Powers and Abilities
Terraspin can retract into his shell and blow very strong and powerful winds out of the holes on his front side

The black spots at the end of his flippers can extend into finger-like claws, they look sharp, so a scratch might be painful.

Terraspin can fly by pulling into his shell and blowing air out to push himself along or spinning his limbs like propellers.

When flying or creating wind, Terraspin retracts his head into his body, his fins become triangular and his legs combine into a similar triangular shape. He rotates with his shell staying static and suspended, like a wind turbine.

Terraspin is able to choose whether to be immune to mana and magic or not.

Terraspin can withdraw into his shell, which is hard enough to protect him from most attacks.

Terraspin can spin at high speeds.

Terraspin can suck like a vacuum to pull things towards him.

In Cosmic Destruction, it is shown he can blast himself forward as an attack, or to blast up ramps.

Terraspin possesses enhanced strength, being able to throw a car.

As seen in The More Things Change: Part 2, he is immune to poisonous gas.

Like his species he is able to learn how to use magic.

Weaknesses
If Terraspin's holes on his chest get blocked, his wind powers will decrease.

If Terraspin gets stuck to something and can't spin his arms and legs, his wind powers will be decreased even further.

Trivia

 * Terraspin's name is a mix of terrapin, which is a turtle or tortoise, as well as spin, referencing his ability to do such.
 * Terraspin's DNA came from Galapagus.
 * Terraspin is the second alien to be scanned with the Ultimatrix and not have Ben transform into him during that episode. Water Hazard was the first.
 * Fasttrack, ChamAlien, Shocksquatch, Jury Rigg and Terraspin are the only of the eleven new aliens in Ben 10: Ultimate Alien who have visible lips that move when talking. (with an exception of NRG without his suit)
 * Terraspin is very similar to Cannonbolt. Both reside in their shell for protection and originally are creatures of defense and not offense. Terraspin is the second alien Ben has utilized as a very strong attacker whose species don't take part in combat.
 * In Absolute Power: Part 1, Gwen had used a spell that had slowed Terraspin down, despite that he is supposed to be immune to mana-based attacks. Dwayne stated that "Terraspin wasn't using his powers, but Aggregor was". This means that his mana immunity can be switched on or off.
 * In Cosmic Destruction and Absolute Power: Part 1, Terraspin's eyes are peeking out of his shell while he's hovering.
 * Terraspin resembles the Japanese monster Gamera. Both were turtle like in appearance, both could fly, both look roughly similar, both could draw into their shells and both could spin while in their shells either as an attack or a form of flight.
 * Terraspin appears as a playable character in Ben 10: Game Creator.
 * Terraspin does not say anything except his name until Absolute Power: Part 1.
 * Terraspin is the Alien Of The Month in March.
 * Terraspin is one of five aliens in Cosmic Destruction that can double jump. The other are Water Hazard, Swampfire, Big Chill and Spidermonkey. Coincidentally the other four aliens can grab and hang onto ledges in the game.
 * In Season 1 of Ultimate Alien, Terraspin's voice was deep and breathy, but in Season 2, he sounded like Water Hazard. In Simian Says, it appears that he once again uses his original voice.
