Armored Armadillo

Armored Armadillo was a Maverick Hunter from the 8th Armored Division under Sigma and was a very loyal soldier. When his master rebelled against humankind, he followed suit only to be loyal.

He also has the best stage music in Mega Man X. Which is a good thing, because you need to play that stage kind of a lot to get the Hadouken.

Maverick Hunters
Armored Armadillo defeated Wire Sponge, Morph Moth, and Wheel Gator in the first three rounds, and Blaze Heatnix in the fourth. However, he lost to Storm Eagle in the finals.
