Huanglongmon

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.[4]
