Magma Dragoon

Magma Dragoon, known as Magmard Dragoon (マグマード・ドラグーン) in Japan, is one of the Mavericks in Mega Man X4. He also appeared as the boss of the training stage of Mega Man X5. As his name implies, he is based on a dragon.

Magma Dragoon betrayed the Maverick Hunters and became a Maverick himself, attacking in Sky Lagoon. He is sort of a parody of the Street Fighter series, yelling out "Hadouken" and "Shoryuken" when attacking. X can defeat him easily with Double Cyclone. Zero has a bit of a harder time. He will have to get creative in order to damage him with the Raijingeki. But in the first encounter with him in the Volcano, if you can bring the Ride Armor with close to full health, you may be able to defeat Magma Dragoon before the Ride Armor gets destroyed.

When you defeat him in the first encounter, he apologizes for his actions, stating how he wanted power to defeat X/Zero, and then a mysterious man offered power, which he simply couldn't refuse.

Most bosses show the ability that you gain during the fight. For X, his Rising Fire could be Dragoon's kick that brings him to the ground. Zero's Ryuenjin maybe the Shoryuken.
