Kevin Marks is a Major in the United States Air Force and a senior officer aboard several Earth vessels, including the Prometheus, the Odyssey, the Apollo and the Daedalus with Marks's most recent assignment being the George Hammond which is under the command of former SG-1 team member, Colonel Samantha Carter.



Marks in 2005 while on the Prometheus

As a Lieutenant, Marks originally served in an auxiliary control room aboard the Prometheus, where he used the ship's Asgard sensors to detect and map the exterior of a subterranean structure beneath a hilltop in Glastonbury Tor, England. He was able to define a large main cavern as well as a network of smaller tunnels and caves, but couldn't beam them in. After Vala suggested using the ring transporter instead, Marks told them that the Prometheus could lock on if there was in fact a set of rings in the cavern, but their radios wouldn't work. After SG-1 succeeded in finding the Ancient treasure, Marks was involved in cataloging the items recovered from the site, locating the Ancient long-range communication device among the collection. (SG1: "Avalon, Part 1", "Avalon, Part 2")

Marks later assumed a bridge post as the Prometheus weapons officer where he served during the mission to Kallana where the first Ori Supergate was encountered. (SG1: "Beachhead")

He later helped in the search for the naquadah bomb and helped beam the building it was in into orbit. (SG1: "Ex Deus Machina")


By early 2006, he had been promoted to the rank of Captain. He piloted the Prometheus on its final mission, to destroy an Ori satellite over Tegalus. When the satellite's attacks left the vessel badly crippled, Colonel Lionel Pendergast sent Marks with Lt. Colonel Samantha Carter to attempt repairs to the sublight engines. During their journey through the ship, a second wave from the satellite struck the ship, resulting in Marks's left arm being injured with Carter saving him from falling while Marks was climbing down a ladder. After Marks had his left arm placed in a sling, he and Carter proceeded with their work and although they tried, their efforts ultimately proved unsuccessful. When Pendergast ordered the Prometheus to be evacuated, Carter beamed him into the Caledonian Federation although Marks was clearly hesitant to leave. (SG1: "Ethon")

Marks on the Odyssey in 2006

Following this, he was promoted once again, to Major, and assumed a bridge post aboard the Odyssey, often but not always as the ship's pilot. He took part in the battle with Ba'al's Ha'tak. (SG1: "Off the Grid")

Marks in 2006

Later, he took part in the Battle of P3Y-229. He was fortunate to survive the massive Ori invasion, as his ship was only one of two out of a dozen ships to survive the battle although the Odyssey suffered great damage after being attacked by the Ori warships. (SG1: "Camelot", "Flesh and Blood")

He joined SG-1 on a mission to a planet that had fallen to the Ori. He detected an energy wave coming from the Stargate and Colonel Paul Emerson ordered him to beam them aboard which Marks did. (SG1: "Counterstrike")

Marks knocked unconscious by the Lucian Alliance's attack on the Odyssey

When Lucian Alliance forces under the command of Anateo ambushed the Odyssey and chased it into a minefield, he was knocked unconscious by the attack and captured by the Alliance. He helped Dr. Daniel Jackson and Vala Mal Doran retake the ship and assumed his post on the bridge. When Netan arrived, despite being the ranking officer with Lt. Colonel Samantha Carter trying to repair the hyperdrive, he turned to Daniel to act as the ship's commander and seemed amused by Daniel's efforts to take on that role, correcting him when Daniel told him he "should probably prepare to return fire", telling Daniel he's always prepared, he just has to push a button. When Teal'c contacted the ship asking for a beam-out to the Odyssey, Daniel ordered Marks to do it and Marks beamed Teal'c and Lt. Colonel Cameron Mitchell to the bridge. (SG1: "Company of Thieves")


He and the Odyssey embarked on a mission to an unnamed planet to destroy the Naquadah being stockpiled by Arkad and the Illac Renin. He fired on a Tel'tak that was trying to escape and destroyed it, causing a massive secondary explosion. (SG1: "Family Ties")

Marks in 2007.

Marks piloted the Odyssey on its mission to Orilla. When three Ori warships exited hyperspace, he used the newly installed Asgard plasma beam weapons to destroy one of the ships. Later, he along with the rest of the crew were transported to P3X-474 and used the Stargate to return to Earth after the Ori proved able to track the ship. (SG1: "Unending")

Marks in 2007.

Marks was on the Odyssey with SG-1 on a mission to the Alteran Home Galaxy in order to find the Ark of Truth. He was on the ship to hold it off from being taken over by the rebuilt Replicators. He and Lt. Colonel Samantha Carter barricaded themselves in the Asgard computer core room and searched for the deactivation command. When the Replicators were seen attacking, Marks helped Carter fend off the Replicators with both of them firing P90s at the Replicators with this also marking the first time that Marks was ever seen wielding a gun let alone firing it, suggesting that Marks had recently received weapons training. They were unable to find it in the Asgard computer core but Lt. Colonel Cameron Mitchell was given the location by James Marrick. (Stargate: The Ark of Truth)


Marks was later reassigned to the Apollo when it was upgraded with the Asgard plasma beam weapon. He was taking part in holding off the Asurans and their fleet of Aurora-class battleships so Dr. Rodney McKay and his team could destroy Asuras and wipe out the Pegasus Replicators. This seemed to be more of a temporary posting as he has been seen most recently on board the Daedalus commanded by Colonel Steven Caldwell. (SGA: "Be All My Sins Remember'd")

Marks served on the Daedalus when it went to the planet M2S-445, where Teyla Emmagan was held by Michael Kenmore. He successfully destroyed Michael's cruiser on that mission. (SGA: "Search and Rescue")

It was revealed that he recently gave Teyla training on the Daedalus' systems when the ship was in orbit over Atlantis. He offered it to Ronon Dex as well, but he refused. This training came in handy when the team was stranded on the alternate Daedalus. (SGA: "The Daedalus Variations")

Later on, Marks was in the weapons chair on the Daedalus when Todd arrived and was stunned along with the rest of the bridge crew when the Wraith took over the ship. During the ship's descent towards the surface of M6H-987, he tried to regain control of the ship's systems, finally succeeding moments after Lt. Colonel John Sheppard took the Daedalus and Katana Labrea's ship through the planet in hyperspace. (SGA: "First Contact", "The Lost Tribe")


Marks and the Daedalus later attempted to stop the Super-hive before it was fully upgraded but the Daedalus was utterly outmatched, only managing to escape when the hive jumped into hyperspace to attack Earth. (SGA: "Enemy at the Gate")

Marks on the George Hammond in 2009

Marks was at the helm of the George Hammond during the attack on Icarus Base in 2009. He detected a massive build-up of energy from the planet. Commander of the 304, Colonel Samantha Carter, ordered Marks to recall Colonel David Telford and his F-302 fighter-interceptors; the ship was badly damaged and they were going to jump to hyperspace. (SGU: "Air, Part 1")

Later that year, during a return trip from Atlantis on the Hammond, Marks argues for adding a holodeck to the ship. Though Carter thinks they don't need one, Marks states that one would be nice and he thinks that the Asgard computer core probably has the technology to make it happen. Though Carter doubts that they could get the budget for one, Marks suggests that she could since the budget goes through General O'Neill. Their discussion is interrupted by the appearance of the same ship that had chased the Prometheus into a gas cloud five years before. Marks is unable to find the ship in the database and is shocked when it takes down the Hammond's shields to 73 percent in just one hit. After the ship is disabled, the aliens beam away the entire crew minus Carter. After the situation is over, the crew is beamed back and Marks quickly determines that the engines are within acceptable range and they can get underway immediately. Carter promises that they will discuss what happened on the way back to Earth, "no holodeck required." Though confused by the events, Marks smiles at her reference. (SGA: "Pleasure Cruise")
