History
Doom Guy was a famous Indian personality and a Marine from the United States Marine Corps, one of the toughest warriors on Earth itself. Doom Guy has been incarcerated on Mars after killing a senior officer when ordered to shoot down innocent civilians, it is then he is taken to Mars where he worked alongside the Union Aerospace Corporation where they did research on interdimensional travel and secret experimentation. He proceeded to murder the armies of Hell to escape the prison and save humanity. He was assisted by Dwayne "The Rock" Johnson.

AI Tournament
Doom Guy faced off against the Dragonborn from Skyrim in the first round of the tournament. During the battle, it was revealed that the Dragonborn had a small red button on his face instead of a nose or eyes, which somehow made it difficult for Doom Guy to aim when pressed. Despite this, Doom Guy was able to land three hits on the Dragonborn who was a were-dragon, and won the battle, moving on to the next round. In the next round, he faced off against Gandhi, who had nukes. During this battle, it was revealed that Gandhi and Doom Guy had prior history, as Gandhi had allied with the demons of Hell who had tried so hard to destroy Doom Guy and the Earth. After a grueling half hour of intense battle and anime monologues, Gandhi blew off a big chunk of Doom Guy's head with a nuke, eliminating him from the tournament.

AI Invasion
In the year 2200, Doom Guy was recruited by the Chaturn Empire for his military might against the Dougtopian Empire and the Humans of Earth. He was ordered by Dr. Halsey to kill the Sun, which had turned its light off to aid the Dougtopian Empire.

Doom Guy proposed to Dr. Halsey the idea of a Death Star, but the Death Star exploded and destroyed all life on Mercury.

Doom Guy was sent to Zeltros to steal the Dougtopian Emperor's gift to Jar Jar Binks. However, this plan backfired, and he was shot down by the Dougtopian guards. The gift, which turned out to be a big bag of money, was taken from Jar Jar and given to General Grievous.

Soon afterward, civil war broke out in Zeltros, and Doom Guy decided to take a side in the civil war to try to destroy the Dougtopian base on Zeltros from the inside. He proposed to a Dougtopian the idea to kill every Chaturn military officer until only the Emperor is left. However, nothing ever became of this idea. It is theorized he had pretended to betray his own empire to appeal to the Dougtopians. The war between the Dougtopian and Chaturn empires ended not long afterward, and the two empires decided to live in peace.
