An ancient phantom Digimon whose activity records remain in the ancient Digital World. Rumors suppose that Ukkomon can grant the wishes of others, which is why it is said that many other Digimon gathered around it, flourished, and formed villages. However, as records of Ukkomon were cut off with the catastrophic destruction of the ancient Digital World, this Digimon is thought to have been wiped out.
For its special move, Whirlpool Spin, Ukkomon spins its body like a top, then crashes into foes. Liar Dream is a technique in which it hijacks an enemy's consciousness after locking eyes with them.
