Garrus Vakarian, originally an uptight Citadel Security officer, joined Commander Shepard on the search for Saren. After saving the Citadel, space, and all of time, Garrus returned to the Citadel. Quickly realizing that the Citadel was boring, Garrus ventured to Omega, the corrupt counterpart to the Citadel. While on Omega-for approximately two years- me managed to get roughly every citizen of the Omega station to want to kill him. Commander Shepard had to save him from this situation because he was a pussy. He decides to join Commander Shepard's crew once more, but has a habit of saying "Can it wait for a bit? I'm in the middle of calibrations." Garrus, albeit a pussy, became famous for his love of calibrating.
