Armed MadLeomon is an Undead Digimon. It is the "Weapon-frenzy Mode" (凶器乱舞形態 Kyoukiranbu Keitai?) of MadLeomon, who gave itself a chainsaw as well as even more modifications. Due to its repeated modifications and unbalanced chainsaw, intense pain is always running through its body, enraging MadLeomon. Because it is unable to stay still, due to its pain, it sees anything reflected in its eyes as an enemy, and attacks.
- The Lion Sleeps Tonight: Chops things up without caring whether they are alive or inanimate, while looking as if it is trying to completely shake off its arm and detach the chainsaw. The Lion "Sleeps" when its hunger is satisfied, that is, when it has preyed upon an opponent. In order for the Lion to sleep, it must also defeat that opponent.
- Lion Heart: Runs wild and pierces the ground with its chainsaw, creating fissures which swallow the opponent. The appearance of the torn and broken ground, caused when Armed MadLeomon's destructive impulses come to the surface, is the very embodiment of its mind.
MadLeomon grows in size and gains armor as well as a chainsaw for its right arm.
