Shin Megami Tensei
As the one responsible in leading the forces of the Gaian Church in order to intervene in God's summoning on the Great Cathedral and bringing forth a world of survival of the fittest, Asura stands in his chambers located on the heart of the last floor basement of the messian cathedral as the last enemy and final boss fight the protagonist must face in Law and Neutral alignments; while serving as a non-playable ally if he is Chaos aligned, providing aid in the attainment of the "Devil Ring"--a valuable item needed for the final showdown against Michael to become available. In constrast to this, Asura's own throne room is inacessible unless the player have the "Angel Ring" in his possession, but only if he follows the Law route. No item is required in the Neutral path.

He poses as the leader of the gaian army that have taken control of the inferior part of the Cathedral, and serves as the most powerfull servant of Lucifer on Earth, guiding his demon generals on the complete obliteration of the messian people along the Chaos Hero and his female partner Rie.

After encountering the hero, Asura mocks him. Stating that "to have betrayed one who cared about [him] (reffering to Chaos Hero) in order to follow the orders of one who has done nothing for [him]", he is truly a "shining exemple of a servant of God". With that said, Asura proceeds to engage the heroes in the final battle, where he is slain and the balance of the world finally restored.
