Terraspin is a new alien that will appear in Ben 10: Ultimate Alien. It is hinted that Ben may obtain this form in Escape From Aggregor.


He is a green turtle-like alien and his name is a combination of terrapin, which is a type of turtle, based on spinning.


His powers are based on wind. He can retract into his shell and blow wind out of the holes on his front side. He can also use his flat hands like fans to blow wind. He can even fly by pulling into his shell and blowing wind out to push himself along.
