Galapagus

Galapagus is one five aliens who was captured by Aggregor. He is from a peaceful planet called Aldabra. He is the Codon Stream's DNA sample for of his species.

Abilities
Galapagus' powers include the following: he can jump up in the air and his arms and legs will start spinning like a tornado. His powers are based on wind and flight. He has a lighter skin color than Terraspin does. He is also very strong, able to rip a street pole out from the ground and swing it with ease. Despite his peaceful nature, he has shown he can be very capable in battle upon learning how to fight.

Ultimate Alien
He first appeared in the Ben 10: Ultimate Alien episode Escape From Aggregor, when he goes on a rampage. While Ben, Gwen and Kevin are fighting Dr. Animo, he attacks their hometown of Bellwood.

He shows to be able to hold his own against Kevin, Big Chill, and Ultimate Big Chill. Eventually, Gwen realizes that with all the power he has, he hasn't harmed anyone and suggests to Kevin to use his Plumber's Badge (which works as a universal translator) to allow Galapagus to talk in their language. He then explains that he went on his rampage in hopes that he would draw the attention of the famous Ben 10 who he begged to help him get back to his home planet. He explains the tale of how Aggregor attacked his home planet, captured him, and imprisoned him with the other four aliens he had captured: Bivalvan, P'andor, Andreas, and Ra'ad. When the five attempt to escape Aggregor's ship, Galapagus suggests using his communicator to send out a distress message, and was assisted by Bivalvan and Ra'ad. Even though he and the other aliens are put back in the cell, Galapagus's SOS message is heard by Magister Prior Gilhil, who boards Aggregor's ship and finds the five aliens, only to be attacked from behind by Aggregor. Bivalvan, P'andor, Andreas, and Ra'ad manage to escape again, but Galapagus seemingly betrays them to Aggregor in exchange for his own freedom. When Aggregor admits he wasn't going to free Galapagus, the Aldabraian admits he didn't intend to betray the others and leads the escape to the shuttle which Aggregor shoots down and causes to crash on Earth. Afterwards, Galapagus, P'andor, Andreas, and Ra'ad each split up to find a way off the planet while Bivalvan stays with the shuttle and attempts to repair it. After Ben samples his DNA for the Ultimatrix, he has Galapagus taken back home in a Plumber spaceship. However, Galapagus finds out the pilot is Aggregor in Ghilhil's Plumber suit. Galapagus is seen at the end of Andreas' Fault as Aggregor puts Andreas inside a statis pod along side him, Bivalvan, and P'andor.

Trivia

 * His name is maybe based on the Galápagos tortoise, which are the largest living tortoise of the Galápagos Islands.
 * In his premiere episode, An Easter egg (this was on purpose) in this episode: after Galapagus sends a distress call, he turns around to see Aggregor subduing Bivalvan and Ra'ad, here a Plumbers Badge can clearly be seen on Galapagus's chest.
 * While all of the escapies technically do fight Ben, Galapagus is the only one to really find peace and seek Ben's help (Andreas was just a henchman)
