Gallery Stage

Gallery Stage (鉱山ステージ), known as Energy Mine Ruins in Mega Man Maverick Hunter X, is Armored Armadillo's stage in Mega Man X, Mega Man Maverick Hunter X, and Mega Man Xtreme.

As this mine is a prime source of raw materials needed to manufacture weapons, Sigma ordered Armored Armadillo to capture the mine to keep a supply of materials. The Hadoken can be found in a secret Light Capsule above the boss shutter.

In Mega Man Xtreme, a digital reproduction of the mine appears in the Mother Computer from the Hunter Base.

Items
One Sub-Tank, three large energy capsules, one Heart Tank, and the Hadouken capsule.

Rockman X manga
After Sting Chameleon's defeat, Armored Armadillo challenged X to a duel in a fortified agonium mine in the F Country (F国アゴニウム採掘場). At first X has trouble against Armadillo, but he used the mine's agonium, a mineral that reacts to fire, to interfere with Armadillo's heat sensor. After Armored Armadillo's defeat, Vile destroyed the mine and all inside, including Armadillo and his subordinates. Angry, X goes after Vile in a nearby ghost town.

Irregular Hunter Rockman X
While investigating the theft of rare minerals, Zero found that the Maverick Kinkō Sōdā and his subordinates where behind it, and attacks them in the "Zalts Mine" (ザルツ鉱山) alone. Sigma orders X to help Zero finish the Mavericks, but also says that Zero's behavior is suspicious and X should keep an eye on him. After thinking a bit, Sigma believes that Zero may be a problem for his plans, and orders Armored Armadillo to finish Zero, saying that he may be a Maverick.

Inside the mine, Zero and X defeated Kinkō's minions, and Armadillo appears to attack Zero. X can't believe that Sigma labelled Zero a Maverick, and he tries to talk with Armadillo. As Armored Armadillo won't listen to him, X fights him to buy time for Zero to finish his task, gaining the Head Parts during the battle. Zero finds Kinkō Sōdā and destroys him, and later returns to assist X. Seeing he is in disadvantage, Armadillo retreats. After this, Zero decides to investigate why Sigma thinks he is a Maverick, and tells X to return to the Maverick Hunters to avoid being considered a Maverick.
