Asuramon

Asuramon is a Wizard Digimon whose name and design are derived from the mythological Asura. It is a legendary Digimon which possesses four arms and three faces. It suddenly appeared within a computer as it was analyzing ancient Hindu cultural documents. Of Asuramon's three faces, one is a face of wrath, one is a face of mercy, and the last is a face of blessings. Contrary to its outer appearance, it honors justice, so it is said that if it sees injustice it will thoroughly attack it without yielding, and it can certainly be said that its personality is like an avatar of a god of light.

Digimon Frontier
Presumably one of the Digimon who lost their Fractal Code to Mercurymon, Asuramon is the guardian of Sakkakumon's Fire Sphere, a volcanic landscape. When Tommy Himi was trapped in the sphere, he was attacked by Asuramon but then Asuramon again appeared as a hooded figure. He told Tommy that he wanted to help the boy look for the other DigiDestined, being overly friendly all the way, until Tommy realized that his idea of friendship doesn't work. Enraged, Asuramon burned his cloak away, revealing his true form and demanded the boy hand his Spirits over. Kumamon was at a great disadvantage due to the environment but he nevertheless was able to drive Asuramon over a cliff into the lava. However, Asuramon emerged from the lava unharmed. He was finally defeated when Kumamon changed to Korikakumon and destroyed him, thus deactivating the Fire Sphere. As Tommy was scanning his fractal code, Asuramon's angry red face rotated to his happy yellow face, thus showing that he was being purified of his anger and evil.

Attacks
 * Fire Fist of Shiva/The Fist of Asura (阿修羅神拳): Unleashes a Punch from its four arms which possesses the offensive power to completely annihilate the opponent itself. Naturally, when that is used while Asuramon has its face of wrath, it is its last and strongest technique.
 * Multiple Faces (喜怒哀楽)
