Omar Wyatt was serving aboard Griffin when the carrier made its way to the Aster system, to take part in Operation Menelaus. When it seemed as though the mission had been a success and that no forceful action would be needed to regain command of Dragon, Parks sent Wyatt to fetch the Red Devils, who would have been taking the ATAFs through their first test run. Four of the Red Devils were spaced when the Crow's Foot attacked Griffin. Wyatt and Andrea Kennedy survived (although Kennedy later died from her injuries).

Wyatt was next charged with taking care of the White Knights, keeping them in Griffin's hold and escorting them safely about the ship as per Parks' requests. He was finally charged with securing Ifrit after the Pandoran forces had abandoned the vessel, following Zackaria and Hawke's spacings. He found a handful of survivors, who Parks ordered him to arrest and place in the brig.

Wyatt served as Griffin's chief of security for the duration of the Pandoran War, going with the carrier to the core Imperial star systems.

In Sol, he assisted Parks in the hijacking of Cratos, putting him in touch Emilio Swann, so that Parks and the White Knights could sneak aboard a security shuttle to reach the dreadnought. Wyatt was arrested for his part in the heist, but was later released when the Knights successfully returned with the prototype TSB.
