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.
- Taiji (太極 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.
- Yellow Circle (黄廻 Oukai?, lit. "Yellow Rotation"): 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 "Yellow Circle", although this isn't confirmed.
- Fang of the Emperor (皇帝之牙 Koutei no Kiba?): Bites the enemy.
- Dragon Smash
- Emperor's Mace: Strikes the enemy using its tail as a mace.
Huanglongmon's design is derived from the Yellow Dragon of the Center (黃龍 Huáng Lóng?). It is a quadrupedal yellow dragon with a long tail and neck, three toes on each foot, and a claw on each toe. Its body is covered in scales of Huanglong Ore. It has eight red eyes—three on each side of the head, and two on its top. It has two long horns on the back of its head, and six large tusks on its back. It also carries twelve DigiCores on its back.
