Dominique was a short man, and therefore very nimble. He was known to have a very athletic figure and to rarely smile; always business. His Commanding Officer, Jacob Keyes, noted this and approved of the fact that he could rely on Dominique in any type of situation.
Early Military CareerEdit
Iroquois and AutumnEdit
In 2552, Dominique served under Keyes aboard the UNSC Iroquois. By the Battle of Sigma Octanus IV, Dominique was the Iroquois's communications officer  and later transferred to Keyes' subsequent command, the UNSC Pillar of Autumn as part of the command crew.
Dominique was present at the Battle of Installation 04, and he was most likely killed when the Covenant executed the entire command crew, though he was not mentioned.
- He has a tattoo of a Besell function around his left wrist.
- While Dominique is mentioned in Halo: The Fall of Reach, and suspected of being the Autumn's first officer, he is not mentioned in Halo: The Flood. Specifically, he is not mentioned as being killed with the rest of the command crew when Keyes is captured by the Covenant. Therefore, his activities after the arrival at Installation 04 are unknown. It is possible he was killed when the Pillar of Autumn came under attack and was boarded.
