Miles O'Brien


 * For the mirror universe counterpart, see Miles O'Brien (mirror).

Miles Edward O'Brien was a human male born on September 1st, 2331. He has served Starfleet as Transporter Chief aboard the USS Enterprise (NCC-1701-D) from 2364 to 2369, Chief of Operations aboard starbase Deep Space Nine from 2369-2375, and as Chief engineer of the USS Defiant (NX-74205) from 2371-2375.

He has two brothers, but his mother was a fosterer who raised other children...possibly 'only' one boy and two girls (DS9 episode: "Whispers", novelization: Trials and Tribble-ations and TNG novel: Imbalance). Miles, having grown up in a traditionally Irish setting was a very practical man. Most times (when feasible) he preferred an au natrel approach to food, recreation etc. rather than tech-even though that was a trade he specialized. (TNG episode: "The Wounded") His pragmatic, 'everyman' approach carried over into his DS9 posting. As a chief warrant officer, he saw himself as an equal to his fellow crewmates superior or subordinate and disliked titles, such as "Sir". Always inovative and open to new concepts, O'Brien believed in engineering to be simple for the average Layman. (DS9 episodes: "Visionary", "Trials and Tribble-ations") His grandmother raised him to follow her advice when combining talking with eating, "You end up doing neither very well!" (Quotable Star Trek )

In 2376, while teaching at Starfleet Academy, O'Brien assisted the Starfleet Corps of Engineers when a alien artifact threatened to destroy San Francisco. (SCE eBook: Aftermath)

In September of 2376, Miles, his wife Keiko, and their children Molly and Kirayoshi, visited Joseph Sisko in New Orleans and later accompanied him to Bajor to attend the birth of his grand-daughter.

While in the Bajoran system, the Chief helped out his old friends on DS9 during the Parasite crisis, and attended Bajor's induction into the United Federation of Planets. (DS9 novels: Mission Gamma: Lesser Evil, Unity)

O'Brien was later detatched to the Starfleet Corps of Engineers on the planet Cardassia as a part of the Federation's relief efforts, while Keiko was in charge of the planet's botanical renewal efforts following the Dominion War. (DS9 novel: WoDS9 volume one: "Cardassia: The Lotus Flower")

Alternate timeline
A parallel universe Miles O'Brien existed in a universe where, among many differences, the first Borg invasion was successful. This O'Brien was married to Keiko O'Brien and had a daughter, Molly, before the Borg attack; both daughter and wife were killed. When the crew of his Enterprise encountered the crew of an Enterprise that managed to repel the Borg, this O'Brien knocked out his counterpart and unsuccessfully attempted to take the counterpart's place.
