An astute Beast Knight Digimon that guards over many of the Beast Digimon inhabiting areas of lush nature. Diarbbitmon's gentle nature leads it to enjoy its time quietly communing with other Digimon. Diarbbitmon defends the lands from any threat, swiftly dispatching enemies that appear with its beloved pair of blades, Moralltach and Beagalltach. Any who dare damage the land must be prepared for the typically well-mannered Diarbbitmon to cut them to shreds until nothing is left. It will also pursue its opponent's allies to destroy them.
Diarbbitmon uses its superlative swordsmanship to cut its foes down with Truskmore Advance, and can summon twin magical spears to pursue foes with Twin Spear Pursuit. It can also surround its enemy with afterimages that slice their target from all directions with Buck Rush, leaving their enemy with no path of retreat.
