A giant Aquatic Digimon with scales that can rival even Chrome Digizoid in toughness. Huankunmon has a warm nature and values clean water, so it protects lake areas from pollution. When it feeds, it jumps out of water and flies through the air as smoothly as it swims through water, satisfying its hunger by swallowing flying Digimon whole. However, its large body makes it an easy target, so it often mixes in with flocks of Xiquemon to travel around. When it moves, Huankunmon will surround the entire flock with a large bubble for protection. Since the bubble refracts light, the flock, including Huankunmon, will be invisible to the outside.
Huankunmon's special move Lonely Bubble produces a bubble from its fin that will seal its target inside, limiting its movement, while Ice Crash lets it spit out a slew of icicles from its mouth. Tidal Vortex summons the spinning tides and turns them into a pillar of water that slams into its enemy.
