Four Great Dragons

The Four Great Dragons (『四大竜』) are four super-powerful Mega-level dragons working behind the scenes of the Digital World. The group consists of Azulongmon, Megidramon, Goldramon, and Magnadramon. However, not all of them are Holy Dragons. While considered an organization in the trading card game, no member has appeared in any series acting in their capacity as a member of the Four Great Dragons.

Azulongmon
Azulongmon is an Exalted Dragon Digimon, one of the four Digimon Sovereigns and the Guardian of the Digital World's Eastern Hemisphere. He is also one of the Four Great Dragons (alongside of Goldramon, Magnadramon and Megidramon). His Japanese name is Qinglongmon, derived from Qinglong, the Chinese astronomical name for the eastern quadrant of the sky. The Japanese word Seiryuu is also derived from this. He commands the Devas Mihiramon, Majiramon and Antylamon.

Azulongmon appears only in times of critical importance and favors the human/Digimon bond though he rarely helps them and others unless needed to.

 Attacks
 * Aurora Force (蒼雷): Curls his body into a circle, releasing a powerful blast of electrical energy.
 * Wind Electricity (風絲華電)

Megidramon
Megidramon is an Evil Dragon Digimon, one of the Four Great Dragons. His name comes from the word "Megiddo", the place where Christians believe the final battle between good and evil will take place. He is a rare (in fact, unique in every single DW) species whose reason for existing is unknown, but is said to be one of the very incarnations of the Digital Hazard, a power of malice that is sealed away by an unknown "force". However, when that power is awakened, he creates a system meltdown which could destroy the Digital World.

Attacks
 * Megiddo Flame:: Exhales the fires of hell upon its enemy.
 * Hell Howling: Megidramon howls while facing the enemy; the shock of the sound itself is critical to most weaker Digimon.

Goldramon
Goldramon is a Holy Dragon Digimon and is the greatest of the Four Great Dragons. A Holy Ring is attached to his arm. Amon of Destruction is sealed in his right hand, while Umon of Creation is sealed in the left.

Attacks
 * Gold Flame (God Flame): Releases a powerful holy flame.
 * Summon (召喚): Summons Amon and Umon to attack his opponents.
 * Amon of Crimson Flare is a dragon sealed within his left arm. Amon administers destruction.
 * Umon of Blue Thunder is a dragon sealed within his right arm. Umon administers creation.

Magnadramon
Magnadramon is a Holy Dragon Digimon and one of the Four Great Dragons.

Attacks
 * Fire Tornado (Holy Flame): A spiraling flame is shot from the mouth.
 * Dragon Fire (Apocalypse): Calls down energy bolts from the heavens to strike her opponents.
 * Hermit Fog: Sprays forth a mist from her mouth that corrodes anything that it touches.
