Captain Maddox Khan is a former Human inmate upon the penal colony, Callisto, who became the leader of the Free Fleet's Omega Company.
Maddox, along with Akari Lane, was instrumental in the insurrection that happened at Callisto and lead his fellow inmates in overthrowing the guards and taking control of the colony before the Free Fleet arrived shortly thereafter. Even in the face of an unknown alien force, Maddox garnered the respect and support of his fellow inmates through his fearless resolve.
While waiting to be sold by the Free Fleet as livestock, the Vendal attacked the ship holding the inmates. Once again, Maddox lead the Humans through the ordeal by sheer force of will causing the Free Fleet to recognize the potential of the Humans for military use. He along with the remnant of the Humans enlisted with the Free Fleet.
In the coming years, he and the rest of his fellow former inmates were given intense training. Many not only failed the training but lost their lives in the process, but those who endured are now lead by Captain Maddox Khan as the Omega Company, one of the most feared divisions of the Free Fleet.
The men and women of Omega Company hold Captain Khan in the highest regard and show the utmost loyalty to him, even more so than Commander Mezer Juul. Sergeant Kemran James even going as far as to refer to him as "God".
