Ninjamon

Ninjamon (Igamon in Japan) is a Mutant Digimon who uses the Iga-style ninja skills. He wanders the Digital World learning new information. It performs covert operations, hiding in the trees or underwater where he is difficult to see. Ninjamon do covert operations in the Digital World for Digimon Kings as hired assassins. They rarely roam around the Digital World without a mission, task, or quest.

Ninjamon specialize in spying and moving around unnoticed. Ninjamon's arsenal includes a ninja sword, shuriken, kunai, and smokescreen bombs. He is also a master of ninja skills: camouflage, stealth and bunshin (creating duplicates of himself).

While everyone slept, Ninjamon sneaked a Dark Spiral on ShogunGekomon and he went on a rampage. While the others battled ShogunGekomon, Floramon and Mushroomon, Shurimon engaged Ninjamon in a fight even when the Control Spire was destroyed and Ninjamon was freed to see who was better ninja master.
