Galapagus

Galapagus is one of five Andromeda Aliens who were captured by Aggregor. He is from a peaceful planet called Aldabra. He is the Codon Stream's DNA sample origin for the Geochelone Aerio species. Despite his peaceful nature, he has shown he can be very capable in battle upon learning how to fight. He provided Ben with the form of Terraspin.

Appearance
Galapagus looks exactly like Terraspin except has white eyes instead of green and lacks the Ultimatrix/Omnitrix symbol.

Ben 10: Ultimate Alien
Galapagus 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 and Big Chill. Eventually, Gwen realizes that even 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 understand what Galapagus is saying. 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 Aldabra. He explains the tale of how Aggregor attacked his home planet, captured him, and imprisoned him with four other aliens: 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 S.O.S. message is heard by Magister Prior Gilhil, who boards Aggregor's ship and finds the five aliens, only to be attacked and murdered 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, he admits he didn't intend to betray the others, but betrays Aggregor and leads the escape to the shuttle which Aggregor shoots down and causes them to crash on Earth. Afterwards, Galapagus, P'andor, Andreas, and Ra'ad all split up to find a way off Earth 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 status pod along side him, Bivalvan and P'andor.

He was also shown in Ultimate Aggregor, where he was hypnotized along with the others by Aggregor, and he presumably died when Aggregor absorbed the 5 Andromeda galaxy aliens.

As of the end of Absolute Power: Part 2, Galapagus, as well as all the other Andromeda Galaxy Aliens, came back to life after Kevin was turned back to normal.
