Before Becoming a Guardian/Backstory
Xaush-367 (Canon brother of Viper-1) was born in Russia, at an unknown date and time, presumed to be the early 2000s. He grew up in a simple life, often taking care of his little brother, now known as Viper-1. After years of watching over him, Xaush was injured from being hit by a car. To continue protecting his brother, and to get around his injuries, Xaush became an Exo, officially adopting the name Xaush-367. After a few more years, his little brother became tired of being protected, and became an Exo as well, adopting the name Viper-1. After a few years, an attack conducted by the Fallen struck Russia, leading them to evacuate into the Cosmodrome. Xaush was equipped with a weak shotgun, fending the Fallen off with a few other survivors. The Fallen eventually began overwhelming them, leading to Xaush-367, Viper-1, and a few other brave survivors to hold off the Fallen as the rest of them evacuated. They stood up against the Fallen for a good while, but sadly were slain in battle. Most who stood back and fought became guardians, including the two Exo brothers.
After Becoming a Guardian
Early days
Several years after the attack, Xaush woke up during the events of The Red War, completely being "deceased" during the events of the first game. His eyes slowed opened to see a floating mechanical being, and the light of the sun. The Ghost quickly told him that they weren't safe there, and that they needed to move quickly. While traversing though the Cosmodrome, they encountered several Fallen crawling on the walls. Xaush ran forth, and grabbed a machine gun, that he used to tear through the approaching Fallen, eventually blasting his way into an open field, with a few ruins, a giant Fallen Walker in the center, and a few other new Guardians just waking up. With his newly found Light powers, he and the other guardians easily took down the Walker, and any Fallen fighting with it. Xaush was an Arc Warlock, capable of turning the light into electricity, and easily vaporizing his enemies. After escaping the Cosmodrome, he saw the Last City for the first time, it baffled him, as he stared in awe. He walked around the city, learning of everyone, and familiarizing himself with everything. He explored the EDZ, and tried getting a grasp of what it meant being a Guardian, the powers of the Light, and the wonders of a Warlock.
The Red War
One day, after a successful Strike at the EDZ, Xaush arrived back at the Tower, and saw a Cabal fleet, calling themselves the Red Legion. The Red Legion's attack on the Tower and Last City struck fear into the heart of Xaush, but he fought valiantly during the battle. After loosing the battle, and being defeat by the Red Legion's leader, Xaush felt powerless against this new threat. He thought he was dead, and suck refuge back at the familiar zone of the EDZ. After regrouping with fellow survivors at a new camp, Xaush quickly found a shard of the Traveler, and was reunited with the Light, no longer feeling powerless. With the new knowledge of his semi-mortality in mind, Xaush pushed on with the war against the Red Legion, eventually slaying their leader, and ending the war.
