We got one of Isaac's favourite Ben 10 monster from the animated TV series, Armodrillo.
Armodrillo has a yellow-armored body and looks much like a robot. His head is similar to a Greek Corinthian helmet with two ears on it giving him the appearance of an armadillo. Armodrillo has a gray tail and jackhammer parts on his elbows, wrists and hands, creating the impression that Armodrillo is a digging robot. Despite the mechanical appearance, all of these aspects are in fact biological and natural to his race.
