Lamortmon (ラモールモン Ramōrumon) is an ultimate level, Vaccine attribute, Beast Digimon. It resembles a tall, bulky yellow rabbit-beast with two pairs of ears (the front pair being much smaller), black-feathered wings protruding from under its arms, and 3-clawed gauntlets on its hands and feet.

An Ultimate Digimon whose hidden feral instincts have been unleashed. It will immediately swoop down on Digimon that express their disgust towards it and keep smashing them until they stop breathing. Although it is an impetuous Digimon that has uncontrollable impulses, it seems that there are some individuals who are ashamed of and despise their own impulses. The vacuum blades that surround the two "Jūran-maru" longswords it carries on its waist become stronger and sharper the more it unleashes its ferocity. Taming a rampaging Lamortmon is impossible unless one has built a great deal of trust with them.
