Chief Miles O'Brien

Miles O'Brien is a Starfleet non-commissioned officer and chief of operations aboard space station Deep Space Nine, responsible for keeping the station's aging Cardassian-built systems running. A skilled engineer and veteran of the Federation-Cardassian wars, he serves alongside Commander Sisko's crew on the frontier of explored space.

Beaming onto the comics page in 1993, Chief Miles O'Brien made his four-color debut in IDW's Star Trek: Deep Space Nine Limited Edition Preview — right at the dawn of the Copper Age — courtesy of creators Mike W. Barr and Lurene Haines. A fixture of the beloved Deep Space Nine comics universe, he's kept remarkable company over the decades, sharing adventures with the likes of Dr. Julian Bashir, Major Kira Nerys, Quark, and Worf across titles including Star Trek: Defiant and the main DS9 series. With appearances stretching from 1993 all the way to 2025, O'Brien is a quietly enduring presence in IDW's Star Trek comics landscape — the kind of dependable, grounded character who anchors any story he steps into, and a must-seek for any Deep Space Nine devotee building out their collection.
