Armored Armadillo

Armored Armadillo, known in Japan as Armor Armarge (アーマー・アルマージ), is a sturdy armadillo-type Reploid in Mega Man X that is ideally suited to fighting underground. He was the leader of the 8th Armored Unit from the Maverick Hunters. Though he is a stoic soldier who never disobeys an order, he is loyal to a fault, continuing to obey Sigma's orders despite the fact that he became a Maverick and rebelled against humankind. Sigma ordered him to capture a mine that is a prime source of raw materials needed to manufacture weapons, and X had to stop him.

His weapon is the Rolling Shield.

Mega Man X
Armored Armadillo usually begins the battle by encasing himself into a ball and rolling around the room or towards X, proving to be very difficult if the player is unprepared. However, these attacks are easily dodged had X acquired the Foot Parts from Dr. Light earlier. The other attack consists of firing small energy blasts from a laser hidden in his head. He can also use some of his armor to deflect normal shots and absorb energy from charged ones, resulting in him firing quick energy blasts in all directions. He is less likely to guard while shooting, making it the ideal time to attack if one is without his weakness.

One hit from the Electric Spark will make most of his armor pieces fall off, making him more vulnerable. While in this state, X can deal damage to Armadillo even when he is in rolling form. This is due to his armor being kept attached to his body by means of electromagnets.

Rockman X manga
Armored Armadillo is the fourth Maverick that X fights in the Rockman X manga. He has the personality of a samurai, even using a sword, named Purple Garden (紫苑). He first appeared in the forest Sting Chameleon was in and had orders to destroy X, but disobeyed Sigma's orders so he could fight one-on-one against the Hunter. Angry, Sigma scarred his left eye, but decided to let him fight. When X defeated him, he used his sword on himself, as a device on him would make him explode if he betrays Sigma. Vile exploded the local area that Armadillo and his soldiers were, killing them all except for X. Vile talked with X before leaving, giving him the location of an armor upgrade.

Rockman X Mega Mission 3
Armored Armadillo is revived as "Armor Armarge HL", and attacks the Maverick Hunter base with three other Mavericks disguised as a recruit Hunter under the alias "Rot Armor" (ロート・アーマー). In his Hyper Limited form he has a predominantly red color scheme and wears a larger, heavier armor studded with spikes.

Archie Comics
Armored Armadillo and most of the other Mavericks were cloned by Sigma-1 to create an army to challenge X and his heroic allies during Worlds Unite.

Trivia

 * In Mega Man X, although it's difficult to perform, it's possible to skip the re-fight with Armored Armadillo in Sigma Stage 3 by charging Shotgun Ice up and then using the ice sled to zip X into the boss door without hitting an invisible trigger that forces the camera to scroll all the way up. If done correctly, the fight won't be triggered and the opposite door will open as if he was defeated. However, jumping will still trigger the fight, and if X starts entering the next section after the fight begins in that case, Armored Armadillo's sprites will glitch.
 * In Mega Man X, it is possible to hit Armadillo with the Electric Spark without making his armor pieces fall off. This can be done by hitting him right before he curls up into a ball, something easily achieved by releasing a charged shot the instant the fight begins.
 * The beams Armored Armadillo fires in the original Mega Man X game have a remarkable similarity to the Hadouken upgrade, which is also in his stage as an Easter egg when conditions are met.
 * Actually, he is based on two animals at the same time: the Doedicurus Clavicaudatus (MMMHX) and the Screaming Hairy Armadillo (MMX), since he got a redesign and adopted the thorns on the shoulders of the Doedicus.
 * Along with Launch Octopus, Toxic Seahorse and Shield Sheldon, this Maverick is misnamed in the Music Gallery in the Mega Man X Legacy Collection and 2. There, he is Armor Armadillo.
 * Another easter egg is during the first mine cart ride; one of the bats is actually a Batton from Mega Man 2, and it is guaranteed to drop a 1-Up.
 * The way Bounce Man bounces around his room in Mega Man 11 is similar to how the Armored Armadillo does during his Rolling Shield attack.
