Galapagus

Galapagus is one five aliens who was captured by Aggregor. He is from a peaceful planet called Aldabra which has lush grass lands, oceans, and seas. He is the Codon Stream's DNA sample for of his species. His name is a play on the galapagos islands which are famous for their sea turtle populations.

He is seen in the 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 and Big Chill. Eventually, Gwen realizes that with all the power it has, it 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. Even though he and the other aliens are put back in the cell, Galapagus's message is heard by Magister Prior Ghilhil, who boards Aggregor's ship and finds the five aliens, only to be attacked 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. As Aggregor needs to take Galapagus back to his homeplanet in order to use his machine to absorb his powers, it is possible that Galapagus is still alive.

Galapagus's 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. Despite his peaceful nature, he has shown he can be very capable in battle upon learning how to fight.
