Asuramon

Asuramon is a four-armed Wizard Digimon with three faces (Anger, Pity, Happy), though he only uses one of them to speak, depending on his mood. He frightens evil Digimon, but just Digimon have no fear. His Fire Fist of Shiva attack is extremely painful for anyone who gets caught in its blast. It's believed he was the result of a computer analyzing an ancient Hindi document. He can survive in lava.

Some people thought that he was going to appear in the Tamers series as a leader of the Devas; due to his namesake's relation to them in Hindu (as a villain) and Persian (as a hero) legends.

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. He was also the second and last Digimon to be scanned by Tommy, as well as his third time dealing with a fire type digimon (after Candlemon/Wizardmon and BurningGreymon).
