Marcus Rethan

Before the Battle of Earth, Marcus was a special operations scout. He worked in two squads who's names are long forgotten. While within those squads he was injured by an Unggoy and had to leave direct service to the UNSC. His injury prevented him from staying on Reach because the medical research that as needed to be used on Marcus was only used on Earth. He was taken off of Reach where he had served his time as a spec-ops and taken to Earth for the medical research.

After he was healed to full health again he helped train new recruits for the UNSC. Years after he had trained a fair share of recruits he backed away from the job and switched to building ships in the UNSC shipyards.

His job in the shipyard consisted of hauling any excess metal from wrecked or flawed creations. Because he had a dangerous job, he was very careful to begin with, but, like all, he became incautious of the dangers that his job contained. This is one thing that Marcus made a foul move on as he was cut many times by rusted metals and other rusts. Marcus was attacked with gangrene like everyone had expected. This happened just as the Battle of Earth had commenced.

During the battle Marcus went into shock and almost died from it. He lost his memory of things that happened recently and long ago. While everyone during the battle thought only of themselves, Marcus received no medical attention and was forgotten and left to die. No one knew who he was and what he previously did.

After the Battle of Earth not much was remembered about Marcus besides his first name. One day Joseph Anaru found him, knowing his ranks and name, and gave him an offer. Marcus, already dying slowly, without any help, took up the offer.

Soon later he became an OMEGA, battle hardened and ready to die for his masters life, Anaru. Marcus joined up with the FGM later, still being led by Anaru though. Marcus worked alongside Joseph in much of his work, helping and giving advice along with learning how to work with OMEGA constructs. Marcus studied this form of art till understanding them fully. He challenged his skills on making a new body suit for the OMEGAs and with much hard work and time spent finished the battle suit so that he could place it over his main shell with a harder, more durable body armor.

Marcus disbanded from the FGM at the time that Anaru did to join the UNSC. Marcus currently is not art of the UNSC but is following Anaru only.
