Lieutenant Colonel (ranked major in season 1). He is an experienced and a talented US Air Force Officer in Afghanistan, though his reputation is somewhat tarnished when he disobeyed a direct order in an unsuccessful attempt to save the lives of several US servicemen. When called upon to transport Brigadier General Jack O'Neill into the research base that has been established at the nearby Ancient defense facility, Sheppard inadvertently discovers that he not only has the ATA gene (the genetic factor necessary to activate Ancient technology), but that he is naturally proficient at using it. After some doubts, he finally joins the expedition to Atlantis, although Colonel Marshall Sumner makes it clear he is not pleased about Sheppard's involvement in the mission. In Season 1, Sheppard serves as both a Major and later also becomes the military commander following Colonel Sumner's death. In Season 2, Sheppard is eventually promoted to Lieutenant Colonel and still remains as Atlantis's military commander with Sheppard serving as the team leader for the Atlantis Expedition's team, the First Atlantis Reconnaissance Team or AR-1.

is the civilian and also the original leader of the Atlantis Expedition which she does for the first three years. Prior to joining the SGC, Weir was engaged to be married to a man named Simon Wallace but their engagement ended when Wallace refused to join the SGC. Weir originally served as the head of the SGC after General George Hammond was reassigned in the Stargate SG-1 Season 7 finale episode, "Lost City Part 1" with Weir serving in the role as SGC Commander up until her departure in the Stargate SG-1 Season 8 episode, "New Order Part 2" with Weir being replaced by newly promoted Brigadier General Jack O'Neill. After leaving the SGC, Weir heads to Antarctica to lead the research envoy studying the Ancient defense facility that had been discovered in Antarctica, the Ancient city of Atlantis which SG-1 had uncovered during "Lost City Part 2". Weir eventually leads the Atlantis Expedition which is sent through the Stargate to explore the Lost City of Atlantis. Weir is a diplomat and a leader, often making decisions in the hope they will benefit her and her people although she has clashed with others on occasions. In the Atlantis Season 3 finale episode, "First Strike", Weir is left in a coma when a beam that the Expeditions's enemies, the Asurans had created targets the Control Room of Atlantis. Weir survives although she becomes part-Replicator due to the fact that the nanites that were left in her system during the Stargate Atlantis Season 3 episode, "Progeny" have been reactivated. Weir eventually sacrifices herself to give Sheppard and his team enough time to escape during the Stargate Atlantis Season 4 episode, "Lifeline" with her fate being unknown although she later returns as a Replicator in the Season 5 episode, "Ghost in the Machine". Her position as leader of the Atlantis Expedition is later taken over by Lieutenant Colonel Samantha Carter and following Carter's return to Earth by Richard Woolsey.

The IOA appoints Carter as the new commander of the Atlantis expedition early in Season 4 of Atlantis. At the end of the first episode of season five, Carter is recalled to Earth for a Tok'ra extraction ceremony concerning the final Ba'al clone, with Richard Woolsey eventually replacing her as the new commander of the Atlantis Expedition.

While evaluating Weir's abilities, he made a rather poor impression on the expedition members.

is the Chief Science Officer of the Atlantis expedition and a member of the main Expedition team, the First Atlantis Reconnaissance Team or AR-1. Dr. McKay is one of the most arrogant and condescending personalities in the Stargate franchise. He once identified himself as a Mensa member and believes himself to be the smartest person in the city, as mentioned in a conversation between Dr. Weir and Carson in "Hide and Seek". What makes it worse for his fellow team members is that, while he does not possess the wisdom of many of the other characters, in terms of raw intelligence or at least the occasional fits of insight/brilliance, he is. Despite his irritating demeanor, many members of the Atlantis expedition are on friendly terms with him, and McKay is able to keep steady relationships and is close to the people he works with, having referred to them as a surrogate family in a message to his estranged sister Jeannie Miller (played by David Hewlett's real-life younger sister, actress Kate Hewlett).


Ronon Dex

Ronon Dex played by

Ronon was later captured by the Wraith who instead of feeding on him turned him into a Runner, implanting a tracking device in his upper back and setting him loose to be constantly hunted. Ronon later becomes a permanent member of Sheppard's team, AR-1, replacing Aidan Ford who defects from Atlantis after Ford develops an addiction to the Wraith enzyme.

Teyla stays with Sheppard's team, but later helps with evacuating the Athosians from the mainland several times in the face of various threats. In season 1's "The Gift", Teyla and the Atlantis expedition learn that her ancestors were experimented on by a Wraith scientist, and that Teyla is one of the few Athosians who possess trace amounts of Wraith DNA which enable her to sense the Wraith through their telepathic network. Teyla is also a member of the Expedition's flagship team, AR-1 and is also adept at hand-to-hand combat.

In "Hide and Seek", he creates a gene therapy that emulates the ATA gene in normal humans with a 48 percent success rate. Later, during Beckett's capture on the planet M8G-352 in season 3's "Misbegotten", Michael took some of Beckett's DNA to make a clone.

An exploding grenade blows them off a building into the ocean, and Ford's unconscious body and the still attached Wraith are recovered nearly an hour later. Ford is diagnosed to have survived an overdose of addictive Wraith enzyme and as a result begins undergoing mental and physical changes, one of which involves his left eye turning completely black. He eventually leaves Atlantis for good, embarking on a quest to get more enzyme for himself. He later returns halfway through Season 2 where he captures Sheppard's team and recruits them into helping him destroy a Hive Ship.

Asurans

Artificial life-forms composed of nanites, introduced in episode " Progeny" of season 3 of ''Stargate Atlantis''. They are similar to the human-form Replicators of ''Stargate SG-1'' and so are called that in the show. The Asurans were created by the Ancients to combat the Wraith but were ultimately abandoned and seemingly destroyed by the Ancients for being too dangerous, although they were not the weapon against the Wraith the Ancients believed they could be. Extremely aggressive, a small number of nanites thrived and eventually built an advanced civilization. In season 4,

In the series, the replicators are referred to as Asurans a couple of times in the episode where they are introduced ("Progeny"), but, afterwards, they are always mentioned as replicators.

Radim retreats from the city along with the other Genii. In "Coup D'etat", Radim contacts Atlantis with an offer of a ZPM in exchange for materiel support in a coup against Cowen. This is apparently revealed to be a ruse by Cowen after Sheppard and his team are captured while attempting to steal the ZPM. However, after Radim receives news that Dr. Beckett has cured his sister and the other Genii hostages on Atlantis of radiation sickness, he reveals that he has in fact been planning a coup after all, and releases the Atlantis team before enacting his plan to kill Cowen and his elite guard with a hidden nuclear bomb. Radim takes over the Genii government, billing it as a "bloodless coup" as no deaths occurred on Genii territory.

Wraith

The main adversaries on ''Stargate Atlantis'', the Wraith are the dominant species in the Pegasus galaxy. They are biologically immortal hive-based humanoids who feed on the "life-force" of humans, causing them to "lose years" in a way similar to aging. They evolved from the Iratus bug, as the bugs began acquiring the human characteristics of the persons they were feeding on. The Ancients encountered the Wraith, and after a long war with them, the latter drove the Ancients out of Pegasus 10,000 years ago, and now maintain the human worlds of Pegasus as sources of food. The arrival of the Atlantis Expedition in the Pegasus galaxy leads to the Wraith waking prematurely from their hibernation, and the human population of Pegasus is not enough to sustain all of them, leading to bloody conflicts and battles among the Wraith themselves. * "Michael", played by
