Armodrillo

Armordrillo is a new alien for Ben 10: Evolutions. By his name his powers maybe digging underground and turning into a indestructable ball. He is most often confused with Terraspin, though the way to spot difference is in the names: Terraspin is a combination of Terrapin ,which is a type of turtle, and spin, which makes Terraspin the turtle-like alien and Armodrillo the other one.
