Digimon Sovereigns In Digimon Tamers

The Digimon Sovereigns, also known as the "Harmonious Ones", are a group of four Mega-level Holy Beast Digimon who is led by Huanglongmon. The Sovereigns have reigned over and protected the Digital World since the age of myth, and have passed into legend as beings which are extremely difficult to track down. They are difficult to overthrow with the power of ordinary Mega Digimon, as their power is set as the highest authority among other Digimon, with strength that is said to be the epitome of gods. Unlike normal Digimon which only have one DigiCore per body, each of the Sovereigns has twelve DigiCores which float outside their body and channel their immortality and tremendous power. Here is the list of them:

Huanglongmon (Mega)

Huanglongmon is a Holy Dragon Digimon. It is the "Digimon Sovereign" that is enshrined in the Center, as an emperor Digimon who rules the "world". Due to Lucemon, it was sealed underground in the deepest, darkest place. This being is good but also evil, and is called the "Taiji" of light and darkness. Its gigantic body is covered in scales of the special "Huanglong Ore" that boasts of absolute hardness, so inflicting even a single wound upon it is impossible.
Attacks
Taikyoku: Continuously disassembles everything in the Digital World, throughout eternity, into the two extremes of light and darkness, driving it into non-existence before long.
Oukai: Generates a gigantic typhoon of an earthflow on the scale of a natural disaster. There is a theory that Ouryumon's "Golden Armor" technique has its roots in "Oukai".
Koutei no Kiba: Bites the enemy.
Dragon Smash

Azulongmon (Mega)

Azulongmon is a Holy Dragon Digimon. It is the "Digimon Sovereign" that guards the East, and commands the Deva Mihiramon, Antylamon, and Majiramon. Also, it is counted as one of the Four Great Dragons, and is the most deified existence among them. It releases intense lightning strikes, and although it is a divine being, it will not easily cooperate with humans and the weak, and it is not likely to lend help to its allies unless there is something serious.
Attacks
Sourai: Looses intense thunderbolts from the sky, with divine fury.
Fushikaden
Raijin-no-Mai
Aurora Force: Curls its body into a circle, generating an intense burst of lightning.
Lightning Whip: Looses an intense thunderbolt.

Zhuqiaomon (Mega)

Zhuqiaomon is a Bird Digimon. It is the "Digimon Sovereign" that guards the South, and commands the Deva Sandiramon, Indramon, and Pajiramon. It manipulates incandescent flames, and as it has the roughest temperament among the Sovereigns, it burns anything insignificant which approaches it to cinders.
Attacks
Kouen: Releases a swirl of flames comparable to the prominences which jet out during a solar eruption.
Rengokusou: Creates a powerful rush of destructive wind.

Ebonwumon (Mega)

Ebonwumon is an Animal Digimon. It is the "Digimon Sovereign" that guards the North, and commands the Deva Vikaralamon, Kumbhiramon, and Vajramon. It uses phantasmagoric water techniques, and, as the oldest of the Four Sovereigns, it possesses a gentle personality.
Attacks
Mugen: Displays an illusion which generates a dark mist around the opponent, destroying their spirit.
Kokuhyo: Summons huge blocks of black crystals that rains on its enemies.

Baihumon (Mega) 

Baihumon is a Holy Beast Digimon. It is the "Digimon Sovereign" that guards the West, and commands the Deva Makuramon, Sinduramon, and Caturamon. Also, although it is the youngest of the Sovereigns, its power is the greatest among the four. Baihumon is a neutral being just like Azulongmon, and it isn't someone who will generally become an ally.
Attacks
Kongou: Emits a wave from its mouth which converts the opponent completely into metal, making them unable to move while their body rusts, and unable to die until they have completely rusted away.
