SGC Commanders

    Major General George Hammond
Played By: Don S. Davis
First Appearamce: "Children of the Gods"

Was a Bait-and-Switch Tyrant in the first episode, but eventually became a Reasonable Authority Figure who trusted the vast majority of ideas and pitches from our heroes based on their track record, no matter how outlandish. The change was signified when he stopped regularly wearing his USAF uniform in favor of a simple blue shirt with a tie, a dress code that was later followed by his eventual successor, General Landry. Was referred to as "Hammond of Texas" by Teal'c's Mentor, Bra'tac. Was relieved of command in favor of Elizabeth Weir for the duration of the Poorly Disguised Pilot for Stargate Atlantis, who was in turn soon replaced by Jack O'Neill.


  • Bait-and-Switch Tyrant: One of his first acts was to try to blow up an inhabited planet. It wasn't long before he was downright fluffy, though. Hammond was counting down the days to his retirement in charge of a facility gathering dust, when the Gate suddenly reactivated. His actions and decisions throughout most of the first and second series are more or less the result of being just as out of his depth as everyone else, before he eventually rose to the challenge. Partially an Enforced Trope due to the show's Air Force advisers pointing out to the writers that an officer doesn't make general in the modern military unless he's earned the trust of his subordinates.
  • Benevolent Boss: Looks out for the people under his command (even the guests in his facility).
  • Bus Crash: Mentioned by Carter to have died of a heart attack offscreen during season five of Atlantis, in a memorial to his actor. Carter commands the USS George S. Hammond in Stargate Universe, named for him.
  • Catchphrase: "Godspeed" and "You have a go."
  • The Cavalry: Done awesomely in "Lost City", when he commands the Prometheus and leads the F-302 squadron into battle with Anubis's forces just as SG-1 are about to get their asses kicked.
  • The Chains of Commanding: His more malicious acts (like the above mentioned planet bombing) were because he had orders and unlike Jack "I follow my orders."
  • Commuting on a Bus: Starting in season 8 he's given a third star and transferred to the Pentagon to head Homeworld Security. He makes a couple of appearances after that.
  • Da Chief: General in command of Stargate Command and the ones the heroes answer to. Sitting behind a desk is mostly his role. Unusual for the role he doesn't worry about backlash from the President if he tweaks the rules.
  • Desk Jockey: He will venture out into the field in extreme circumstances, but spends much of the series chained to his desk.
  • A Father to His Men: Often acts this in spades towards SG-1. "As long as there is a snowball's chance in hell of my officer coming out of this alive we're going to take it!" He even addresses Kawalsky as 'son'.
    • In "Prisoners", he nearly gets himself imprisoned after he loses his temper at the Taldor for unjustly imprisoning SG-1, likewise, taking his first trip through the Gate to personally negotiate their release.
    • He reveals to Jack that he has his grandkids listed on his autodialer above the President.
    • Lord knows what would have happened in "Chain Reaction" if he had been able to deploy the military forces under his command within the United States.
  • Frontline General: On occasion, usually when the team are in need of rescuing. The most notable examples being "Into the Fire", when he pilots a Death Glider to rescue to team from Hathor, and the above-mentioned moment with the Prometheus in "Lost City, Part 2".
    • He also frequently rushes to the gate room with the iris down even when he doesn't know who is dialing in or what is coming through the other side.
  • Honorary True Companion: Despite the fact that he's their boss, the team make it clear that they consider him a part of the family, and he indicates on more than one occasion that he has a particular fondness for them even though he's not supposed to play favorites. Really driven home at one point when he cancels plans to watch one of his granddaughters (who he adores) in a school play because Daniel is missing.
    • He outright says it in "Heroes Pt 2" when Janet, the other Honorary True Companion, dies. In his words, you're supposed to care for all your subordinates equally, but sometimes you just can't help caring for some of them more.
  • In Harm's Way: During his stint as head of Homeworld Security, he volunteers to take command of the Prometheus again on a search and rescue mission to find the missing Atlantis team and admits that taking part in the battle of Antarctica made him miss the action.
  • Kicked Upstairs: At the end of season seven, he's promoted and reassigned to Washington so that President Hayes can put a civilian (Elizabeth Weir) in charge of the SGC.
  • Line in the Sand: In "Into the Fire" he asks for volunteers to retrieve SG-1 from Hathor's base but states that he isn't going to order anybody. Every single member of military personnel available steps forward.
  • Rank Up: Spent season 8 as the lieutenant general in charge of Homeworld Security, then retired.
  • Reasonable Authority Figure. George "You Have A Go" Hammond very rarely turns down requests from his team and when he does it's for very good reasons. Later in the series, he immediately believes an outlandish scenario told to him by Daniel, who is himself stunned he believes him. Hammond's answer? "The things I've heard sitting in this chair!"
  • Reassignment Backfire: Not a malicious example, but the original plan for his command of the then-unnamed stargate complex under Cheyenne Mountain was for it to be a quiet do-nothing job where he could relax and wait to retire at the end of the year. Well, we all know how that turned out...
  • Seen It All: He gets like this after a while due to several years of dealing with the weirdness his flagship team tends to attract. The above quote gives a good example.
  • Team Dad: To the team. He can occasionally be strict, but it's clear that he cares about them a great deal. He will also occasionally intervene in their personal squabbles.
  • 10-Minute Retirement: The NID blackmail him into retiring in "Chain Reaction" so that they can replace him with a General Ripper type, but he's soon restored after O'Neill and Maybourne do a little blackmailing of their own.
  • Time Travel for Fun and Profit: Forms a Brick Joke in "1969", when Jack borrows some money for his younger self, promising to pay him back with interest. After they return to the present, Hammond informs him that it's now up to $539.50, with interest.
  • Tuckerization: In the Stargate Universe premiere his middle initial is revealed as "S.", just like his actor.

    Dr. Elizabeth Weir

Civilian diplomat appointed by President Henry Hayes to replace Hammond as the head of the SGC when his administration was voted into power at the end of season 7. Despite the team having their doubts, she was quick to prove that she wasn't just a figurehead, and managed to earn their respect before leaving to head up the Atlantis expedition, allowing O'Neill to take command.

Go here for tropes applying to Weir in Atlantis.


  • Cunning Linguist: Claims to speak five languages during her interview with Hayes, and her very first scene shows her conversing in Russian with some random guy trying to get into her taxi.
  • Naïve Newcomer: She's repeatedly shown to be totally out of her depth during her short tenure as the SGC commander, though she copes admirably.
  • The Other Darrin: Originally played by Jessica Steen in the season 7 finale but replaced at the beginning of season 8 by Torri Higginson, who would go on to portray her throughout her tenure as an Atlantis regular.
  • Put on a Bus: She leaves for the Atlantis expedition after four episodes, making way for O'Neill to take command of the SGC.
  • Reasonable Authority Figure: Proves herself to be this by allowing the team to leave in search of the Lost City after O'Neill gets the Ancient knowledge downloaded into his brain, despite Kinsey's objections.
  • Secret Test of Character: Jack and Daniel both subject her to these when she's given command of the SGC. She passes, eventually.
  • Straw Civilian: Subverted. The team suspect that this is the President's agenda by putting her in charge, but Hayes tells her that he didn't choose her just to be a figurehead and she makes it clear that she's not interested in being a puppet leader for Kinsey to rule by proxy.
  • Transplant: To Atlantis.

    Major General Hank Landry
Played By: Beau Bridges
First Appearance: "Avalon, Part 1"

Replaced O'Neill in Season 9 as the commander of the SGC, but was actually closer to Hammond in both appearance and command style.


  • And Starring: Beau Bridges was prefixed with "With" in the opening.
  • Benevolent Boss: He's a reasonable commander, though not as much as Hammond.
  • Cloudcuckoolander: He's got this "thing" about birdwatching.
  • Da Chief: The 2-star General in command of Star Gate Command and the entire Stargate Project.
  • Deadpan Snarker: Especially towards Vala and Woolsey. With Vala it's generally good-natured, with Woolsey...not so much.
  • A Father to His Men: Not quite to the same extent as Hammond or O'Neill, but it's there. Made especially obvious by the following line after Teal'c is taken captive by Ba'al:
    Landry: Teal'c is family. I don't like people screwing with my family.
  • For Want of a Nail: In an alternate universe where the Stargate Program became public knowledge following Anubis's attack on Earth, Landry is a tyrannical President Evil who implemented martial law in the States. Made even creepier by the fact that he keeps the exact same affable demeanor.
  • Frontline General: He goes through the Stargate to confront a Prior at one point. This turns out to be a bad idea, as he subsequently comes down with The Plague.
  • Hidden Depths: He's a keen birdwatcher and turns out to be quite the animal lover in general.
  • Interservice Rivalry: He refers to Marines as 'cocky sonsabitches' and that he never liked them. It's Played for Laughs though.
  • Married to the Job: Led to his divorce and estrangement from his daughter.
  • Officer and a Gentleman: Apart from being a fine general, he is also fond of quoting historical figures like Patton and Churchill.
  • Parents as People: His relationship with Carolyn is strained due to his persistent absences when she was a child, but it's clear that he does love his daughter and is keen to repair their relationship now that she's an adult.
  • See You in Hell: After a Prior gives him a fire and brimstone speech, he replies, "If we're going to Hell, then you're coming with us."
  • Smart People Play Chess: Like his predecessor, he's often shown playing the game in his downtime. He consistently loses to O'Neill, and consistently wins against Mitchell.
  • Suspiciously Similar Substitute: For Hammond; notice a pattern here? However, like with Mitchell, he's shown to have distinct differences from his predecessor. He's signifcantly more gruff and irritable and not quite as reasonable towards his subordinates. Also, while Hammond was favorable and professional towards international concerns about the Stargate, Landry makes no attempt at disguising his contempt for the IOA.
  • Team Dad: For all of SG-1, but especially for Vala once she's accepted on the team.

    Major General W.O. West 
Played By: Leon Rippy
First Appearance: Stargate (1994)

The original commander of the SGC. A decorated soldier, West was a typical authoritarian type and retired in between the film and the series.


Military Personnel

    Major Charles Kawalsky
Played By: John Diehl (movie), Jay Acovone (series)
First Appearance: Stargate (1994)

Another character from the movie. Part of the first mission to Abydos, serving as Jack O'Neill's second-in-command. A year later, he was assigned to lead his own SG unit, only to be infected by a Goa'uld symbiote during his unit's first mission. Didn't survive long after that, but alternate versions of the character appeared in later episodes.


  • And Then John Was a Zombie: Gets taken over by a Goa'uld at the end of the pilot episode, which then proceeds to spend most of the second episode in control of him.
  • Big Damn Heroes: Near the end of the Pilot Movie, SG-1 and Teal'c get pinned down by a Death Glider during the escape from Chulak, and Jack and Teal'c's staff weapons prove useless against it. Then Kawalsky, commanding SG-2, comes over the ridge and blows the Glider away with a Stinger missile.
  • Dead Alternate Counterpart: Inverted. In the main reality he died, but in an alternate reality, he is revealed to be alive and well.
  • Dying as Yourself: Cruelly averted. His final request is to wake up as himself "or not at all", but unfortunately the symbiote fools everybody by lying dormant for a while after the surgery, and it's in control when Teal'c finally puts Kawalsky out of his misery.
  • Majorly Awesome: He doesn't stick around long, but long enough to show how majorly awesome he is.
  • Mauve Shirt. Being from the original movie and prominently featured in the pilot (in which he got more screentime than Teal'c), it looked like he'd be more than just a Sacrificial Lamb.
  • Number Two: O'Neill's second in command on the first mission.
  • Plucky Comic Relief: Tends to be this whenever he shows up, due to his jovial personality.
  • Portal Cut: Teal'c kills him by holding his head half-in and half-out of the event horizon of the active Stargate, causing him to be scalped when O'Neill orders the gate shut down.
  • Posthumous Character: Whenever alternate versions of him show up after his death.
  • Sacrificial Lamb: Starts out as a pretty significant character, only to be killed off early in the first season.
  • Sudden Sequel Death Syndrome: Survives the original movie only to be killed off in the second episode of the series.
  • They Killed Kenny Again: An alternate timeline version of himself in season eight also died.
  • Those Two Guys: With Ferreti in the pilot episode.

    Lieutenant Colonel Bert Samuels 
Played By: Robert Wisden
First Appearance: "Children of the Gods"

General Hammond's original second-in-command. After the events of the original film, Samuels approached a then-retired Jack O'Neill and brought him back to Stargate Command. After the pilot episode, he was reassigned to the Pentagon but eventually popped up again to complicate matters.


  • Chuck Cunningham Syndrome: Disappears after the first episode of the second season, although he returned in an alternate timeline in season eight's "Moebius".
  • Dirty Coward: Once it becomes clear that earth is defenseless against Apophis' forces, he asks to be taken to the alpha site. Hammond denies his request, as they are only sending the best and brightest.
  • Herald: He's the one sent to tell Jack O'Neill about the aliens who came through the Stargate and that he's just been recruited to deal with it.
  • I Warned You: Samuels has an "I told you so" moment when he insists that if Hammond had listened to his warnings about the stargate from the beginning, they wouldn't now be facing the threat of annihilation. Later inverted when Samuels' plan to destroy the ships fails in an epic way, though Hammond is too big a man to actually say anything.
  • Number Two: He is General Hammond's second-in-command, but only for the pilot episode.
  • Put on a Bus: After "Children of the Gods", Samuels gets reassigned to the Pentagon where he spent the next several months analysing SG team missions.
  • Rank Up: Between his first appearance in "Children of the Gods" and his second in "Politics", he's moved up from Major to Lieutenant Colonel.
  • Small Role, Big Impact: Despite only appearing in four episodes, he's the one who approaches Jack O'Neill in the pilot, brings him back to the SGC, and basically starts O'Neill's many years of serving in the Stargate Program.

    Major Dr. Janet Fraiser
Played By: Teryl Rothery
First Apperance: "The Broca Divide".

For some reason, never appeared in the opening credits despite effectively being a regular. The SGC's medical officer, she often saved SGC members and aliens from the brink of death. She was a nurturing, motherly figure, best expressed when she adopted the alien girl Cassandra. Became Samantha Carter's best friend. Had a bridge dropped on her in the season 7 two-parter "Heroes." She was eventually succeeded by Dr. Carolyn Lam in Season 9.


  • Action Mom: When she's seen offworld, she's generally pretty action-y. Even a few times on Earth. After she adopts Cassandra, the mom part of Action Mom comes into play and completes this trope.
  • And Starring: Though she never became a regular, from the second season onward she was listed at the end of the guest star credits with "And Teryl Rothery as Dr. Fraiser".
  • Berserk Button: Threatening her daughter or her patients is not a good idea.
  • Combat Medic: She's an officer in the US Air Force in addition to being a brilliant doctor, so this trope tends to come into play whenever she's sent out into the field.
  • Damsel out of Distress : Even when she's held at gunpoint, it's not a good idea to piss her off.
  • Dead Girl, Junior: Janet Wells, the daughter of the would-be Red Shirt whose life she saved in "Heroes."
  • Dies Wide Open: It's easy to miss since we only see her death secondhand via an in-universe camera, but there's a brief shot of her staring sightlessly up at the sky after she's hit.
  • Doctor's Orders: She's given seniority whenever there's a medical emergency at the base, outranking even Hammond when such situations arise. The only who ever manages to gainsay her is Bra'tac, once, under very specific circumstances. And even then, she threatened to resign over it.
  • Fake Guest Star: Receives guest billing throughout her entire tenure on the show, despite appearing regularly for the first seven seasons and effectively being the sixth member of the core cast.
  • Fiery Redhead: Most of the time, she's a really nice person, but trying to hurt someone she cares about ... may be the last thing you ever do.
  • Heterosexual Life-Partners: Gradually becomes this with Sam. It's implied that they practically raise Cassie together, despite Janet being her legal guardian. The Heterosexual part is occasionally in doubt.
  • Honorary True Companion: For SG-1 and Sam in particular.
  • Meaningful Funeral: Fan opinions on her death and the purpose it served are... divided, but her funeral is widely regarded as one of the most beautiful and moving scenes in the entire series, with Sam reading out a list of all the people she's saved in her role as the CMO that Teal'c put together.
  • The Medic: Not the only doctor on base, but almost always the one seen providing medical care whenever the episode called for it.
  • Majorly Awesome: The medical equivalent of this, although she also sees a fair bit of action, as described above.
  • Mama Bear: At one point, she takes Nirrti hostage and demands that she fix Cassandra. Nirrti was still unwilling to help at first, even with the gun to her head. Then Hammond informed her that Fraiser was Cassandra's mother. Nirrti got a lot more cooperative after that.
  • The Napoleon: O'Neill jokingly calls her a "napoleonic power-monger" at one point, referring to both her diminutive stature and the strictness with which she rules the infirmary. Janet is generally a very sweet-natured person, but she can definitely be scary if her patients are being difficult.
  • Parental Substitute: To Cassandra, the alien girl she adopts after her entire planet is wiped out by a virus.
  • Pintsized Powerhouse: The rest of the cast tower over her, but they're all quick to comply whenever she starts giving out orders. She's also pretty adept in combat situations, despite her size.
  • Rank Up: Went unremarked, but at some point before "Crystal Skull", her rank insignia changed from the double-bar of a captain to the brass leaf of a major.
  • Senseless Sacrifice: How many viewed her death, especially some rat-faced politicians. She saved the man she was treating, who later admits to having some Survivor's Guilt, feeling that he wasn't worth losing her over. He's chosen to honour her sacrifice by naming his unborn daughter after her.
  • Ship Tease: A few hints of it with Daniel, most notably the hand-holding scene from "Rite of Passage". According to Word of God, these moments were never scripted, instead being a Throw It In! on the part of the actors in response to the popularity of the Jack/Sam ship.
    • There's more than a little Les Yay between her and Sam.
  • Super Doc: There are very few medical problems she can't deal with. She's eventually made the Chief Medical Officer of Stargate Command for a good reason. The previous Chief, Warner, retired sometime after season 3.
  • Team Mom: Frequently falls into this towards the team as an extension of her role as The Medic. She's generally the one looking out for mental and emotional wellbeing, as well as their physical health.

    Chief Master Sergeant Walter Harriman
Played By: Gary Jones
First Appearance: "Children of the Gods"

AKA Chevron Guy, sat at the computers and called out when the chevrons were locked. Didn't get fleshed out much until a few seasons in. Eventually became O'Neill's assistant when he took over for Hammond as General.


  • I Have Many Names: The show simply couldn't decide what his name was. The Stargate wiki went with "Norman Walter Davis Harriman".
  • Mr. Exposition: In the first episode of the Retool, he fills the audience (and his fellow technician) in on Mitchell's backstory.
  • Nice Guy: Both on and off the clock.
  • Plucky Comic Relief: When he's on screen for more than a split second.
  • Serious Business: Takes his job (calling out the chevron encoding) very seriously.
  • Shout-Out: to Corporal Walter "Radar" O'Reilly, in name, role, and ability to anticipate needs or orders
  • Spider-Sense: Always knows what O'Neill and Landry want before any announcement over the PA is made.
    Walter: You have to push the button to talk, sir.
    Landry: Sigh... Thank you, Walter.
  • What, Exactly, Is His Job?: His precise job at the SGC is a mystery for most of the series, but is finally answered in the Series 7 episode, "Heroes Part 1 & 2". Turns out that besides Engaging Chevrons, he's also responsible for closing the Iris to prevent any unknown inbound travellers... and that's it! In season 8 he gains the additional job of aide to General O'Neill. In the alternate Bad Future of "2010", we see Walter still working in the SGC, now having been converted into a museum. Of course, it's entirely possible that he simply came with the place when they bought it.

    M Sgt. Sylvester "Sly" Siler
Played By: Dan Shea
First Appearance: "Solitudes"

A technical specialist and chief electrician at the SGC. He's responsible for managing the equipment that provides the massive power requirements of the Stargate.

He's a fairly minor recurring character, but notable for being one of only seven characters to appear in all 10 seasons, the others being the original main cast plus Walter Harriman.

The actor also served at the show's lead stunt coordinator, which as time went on, lead to Siler taking a lot of hits and falls... and we mean A LOT.


  • Butt-Monkey: He's been electrocuted countless times and is often the victim of various other Amusing Injuries. Being played by the lead stunt coordinator for the series tends to invite all sorts of shenanigans, it seems.
  • The Engineer
  • Funny Background Event: He can often be seen wandering around the background of a shot holding a comically large wrench. Several scenes in the infirmary also have him visible in one of the beds, awaiting treatment for his latest mishap.
  • Mr. Fixit: He's usually the guy called on to carry out technical repairs on the gate.
  • Odd Friendship: He has a particular friendship with O'Neill. This is actually a Creator In-Joke: Dan Shea is also Richard Dean Anderson's stunt double for O'Neill.
  • Scotty Time: Lampshaded and averted when the SGC's gate is damaged and half of SG-1 is trapped off-world until it's fixed.
    MSgt. Siler: That'll be twenty-four hours, General. Mimimum.
    Teal'c: Captain Carter and Colonel O'neill do not have that long.
    Gen. Hammond: I'll give you half that!
    MSgt. Siler: Sorry, sir, it doesn't work like that. Twenty-four hours is the best I can do.

    Colonel Robert Makepeace
Played By: Steve Makaj
First Appearance: "The Broca Divide"

A Marine and the original leader of SG-3. Despite a somewhat obnoxious personality, Makepeace was generally considered to be a fairly decent guy and volunteered to lead the rescue operation when SG-1 was captured by Hathor. However, he was later exposed as a Mole for the rogue NID during a sting operation, and was swiftly Put on a Bus.


  • Big Damn Heroes: He leads the rescue operation when SG-1 are captured by Hathor in the season 3 premiere. Slightly subverted, as his men end up getting captured themselves and it takes the intervention of Teal'c, Bra'tac and General Hammond to save them.
  • Colonel Badass: He can definitely hold his own in combat, though we rarely get to see him in action.
  • Fantastic Racism: A subtle example, but he dismissively refers to Teal'c as "the Jaffa" when he's temporarily given command of SG-1, acting as an early tip-off that he might not be quite the stand-up guy he pretends to be.
  • Hero of Another Story: Former Trope Namer. We can assume he saw plenty of action as commander of the SGC's marine unit, but little of it takes place onscreen because, well, the show isn't called Stargate SG-3. Again, becomes a subversion when he's outed as the mole.
  • Interservice Rivalry: A downplayed example, some friendly flyboys/jarheads ribbing, occurs between his team and the Air Force personnel in his introductory episode.
  • The Mole: It's revealed in "Shades of Grey" that he's been using his missions as a cover to steal alien technology for Maybourne and his cohorts.
  • No One Gets Left Behind: Subverts it twice in the same episode; despite enthusiastically volunteering for the rescue mission, he tells Carter and Daniel to consider O'Neill a casualty on finding out that he's been implanted with a Goa'uld symbiote, and later stops Daniel from helping a fallen Marine.
  • Put on a Bus: The last we ever see of him is as he's being arrested, though it seems safe to assume that he's been rotting in jail ever since.
  • Semper Fi: The first important Marine character to be introduced, and he embodies a lot of the stereotypes with his brash personality.

    Colonel Albert Reynolds
Played By: Eric Breker
First Appearance: "Touchstone"

Another Marine, first introduced working at Area 51 but eventually joined the SGC and took over as the leader of SG-3. His team were largely there to support SG-1 during their more dangerous missions, but he became a fairly important recurring character over time.


  • Ascended Extra: Initially introduced as a minor oneshot character, but starts cropping up in more and more episodes after he joins the SGC and especially after taking command of the marine unit.
  • Colonel Badass: He seems to acquit himself fairly well whenever he's out in the field.
  • The Generic Guy: Doesn't have much by way of a personality, even after his appearances become more frequent.
  • Heel–Face Turn: Possibly. He's initially introduced working for the NID out of Area 51 before joining the SGC, but there's never been any reason to suspect he was involved with the rogue element.
  • Hero of Another Story: Picks this up and runs with it after Makepeace's departure, arguably embodying the trope more than Makepeace ever did. He's usually the guy making some kind of discovery in the first five minutes of an episode before SG-1 are dispatched to check it out.
  • Nice Guy: He's generally fairly affable and seems to get on well with all of the main characters, though he's occasionally prone to Open Mouth, Insert Foot.
  • No One Gets Left Behind: Gives a whole speech about this when Ba'al claims to be holding SG-1 hostage shortly after O'Neill's promotion.
  • Number Two: After Hammond's departure, he becomes the military 2IC for the entire base (as a full-blown colonel, he outranks both Carter and Mitchell) and is occasionally given command when O'Neill or Landry are unavailable.
  • Rank Up: Initially introduced as a major, but he's a colonel by the time he reappears three seasons later.
  • Semper Fi: Replaces Makepeace as the show's token Marine character. Which is rather odd considering he was first introduced as an Air Force officer working at Area 51.
  • Suspiciously Similar Substitute: For Makepeace, though he's more toned-down personality wise.
  • Worst Aid: He freaks out at one point when it looks as though he might have to give Hammond mouth-to-mouth, and is incredibly relieved when he comes around of his own accord. As an experienced and high-ranking officer, you'd think he'd know better.
    Reynolds: Excellent! Excellent waking up, sir!

     Lieutenant Kevin Elliot 

First Appearance: "Proving Ground"

A Liutenant in the US Airforce who was recruited for Stargate Command after going through several Training Scenarios. After proving his worth in "Proving Ground," he was assigned to the team SG-17.


     Lieutenant Satterfield

Played By: Grace Park
First Appearance: "Proving Ground"

A Lieutenant in the US Airforce recruited for Stargate Command. She seemed to have an interest in archaeological artifacts and Daniel Jackson.


  • Always Save the Guy: Shows shades of this toward Daniel. In the first training simulation she let her personal feelings for him cloud her judgement and hesitated to shoot him even as he was shooting her team members (in the simulation of course, they weren't in real danger). Even when she sees that he is the leader of the apparently brainwashed SGC, she expresses concern for him in particular and tells her team members "We have to save him." Even though she does shoot him and render him unconscious with her stungun, she uses her own body to shield him from an impending C4 explosion (which never exploded, but the sentiment was there.) Daniel even picks up on it and after the simulation is over jokingly tells her, "Hey, thanks for the save."
  • Apologetic Attacker: In an elaborate training similation, Daniel Jackson is pretending to be the leader of the mind controlled SGC. Satterfield sneaks up behind him and reluctantly shoots him with her Stun gun, then says "So sorry."
  • Distracted by the Sexy: At least from her point of view. During a training scenario, when she and the other new recruits were faced with Carter and Daniel pointing guns at each other and accusing the other of being a Goua'uld, she refused to believe Daniel was a Goua'uld because "she thinks he's cute."

    O'Neill: What's your excuse?
    Satterfield: I didn't believe Dr. Jackson was a Goa'uld.
    Carter: Why not?
    Satterfield: I don't know, Ma'am. That was just my instinct.
    Hailey: She thinks he's cute.
  • Last-Name Basis: Her first name is never mentioned.
  • One-Shot Character: Created as part of Elliot's group for a Lower-Deck Episode and never seen again afterwards.

Civilian Personnel

    Dr.Carolyn Lam
Played By: Lexa Doig
First Appearance: "Avalon, Part 2"

The SGC's new medical doctor, after a season without a recurring character in this role following Fraiser's death back in season 7. General Landry's daughter, played by Michael Shanks's wife (which was a total surprise for him when she was cast).


  • And Starring: Like Fraiser, she was listed at the end of the guest star credits with "And Lexa Doig as Dr. Lam".
  • Deadpan Snarker: She rarely cracks a smile and she can be pretty sarcastic when it comes to dealing with her father.
  • Defrosting Ice Queen: Towards Landry. She starts out very frosty towards him and insists that they maintain a strictly professional relationship, but she starts to thaw out some after seeing firsthand just how stressful his job can be. Watching him almost die from the Prior plague probably helped, too.
  • The General's Daughter: Downplayed most of the time, but in one episode Mitchell chews out another soldier for making a sexist comment about her giving him a sponge bath, warning the guy not to repeat such things around Landry.
  • Hidden Heart of Gold: Used a façade to try and push General Landry, her dad, at arm's length. She was pretty good at it for a while, which led to a lot of wangst on her part.
  • The Medic: As a medical doctor and Fraiser's replacement, this is a given.
  • Mixed Ancestry: Her father is white and her mother is Asian. They met while he was serving in the Vietnam War.
  • Super Doc: Not many doctors are good enough to fill Fraiser's shoes, but Lam pulled it off.
  • Suspiciously Similar Substitute: For Fraiser.
  • What Happened to the Mouse?: Due to Lexa Doig's pregnancy and maternity leave, she only appears in two episodes of season 10. Since the show was cancelled before an eleventh season could be made, the ongoing subplot about her strained relationship with her father is never resolved.

    Dr. Bill Lee
Played By: Bill Dow
First Appearance: "Prodigy"

A brilliant but inefficient civilian scientist at the SGC. Despite being a resident expert in whatever field of science an episode required of him, he was rarely good enough to solve the problem of the week. One of the few characters to appear in all three series.


  • Ascended Extra: Originally part of a one-off group of scientists, he became more prominent and fleshed-out as the series progressed.
  • Butt-Monkey: Often treated as a joke compared to other scientists, with things rarely going well for him.
  • The Cameo: Shows up very briefly in the Stargate Universe pilot when Dr. Rush body switches with him. It makes Lee one of the few characters to appear in all three series.
  • Dude, Where's My Respect?: Much of his role on the show seems to be screwing things up so that Jack and/or Daniel can snark about how useless he is while Sam finds the real solution, despite the fact that he's supposed to be a brilliant scientist in his own right.
    Lee: You know, I keep telling myself that one of these days, I'm gonna do something that actually earns me a little respect around here.
    Daniel: We're all waiting for that day, Bill.
  • Entertainingly Wrong: Most of his theories tend to fall under this, with a particularly amusing example being the time he cited "miniaturization" as a probable reason for the sudden disappearance of Carter and Mitchell (they were actually out of phase).
  • Kavorka Man: He seems to attract quite a bit of attention from the ladies during one episode where he and Carter attend a technology exhibit, much to Carter's bemusement.
  • Lab Rat: As he's not a field operative, he fits this trope even more than Carter, being rarely seen outside of his lab after his unfortunate experience in Honduras.
  • Non-Action Guy: Since season 4 and still going.
  • Omnidisciplinary Scientist: He's done work in physics, engineering, alien technology, alien biology, archaeology and more.
  • Plucky Comic Relief: If he appears, he's more than likely to serve this role.
  • Pop-Cultural Osmosis Failure: When he comes up with a solution in Atlantis, he uses the Twilight Bark as an example, which no one in the room recognizes. He changes the analogy to The Lord of the Rings, which everyone gets immediately.
  • Proud to Be a Geek: A diehard fan of World of Warcraft and not one bit ashamed to admit it.
  • Replacement Flat Character: After Daniel Jackson graduated to Badass Bookworm, he became the new geeky non-action scientist.
  • The Stool Pigeon: After he and Daniel are captured and tortured by Honduran rebels during a mission to retrieve a piece of alien Phlebotinum, he ends up telling their captors everything they want to know before too long.
  • Throw the Dog a Bone: Every once in a while Lee would be the one to save the day. This happened quite a bit more during his appearances on Atlantis, such as when he single-handily figured out a way to send a message to the city using the battlecruiser Daedalus as a relay from the Milky Way to Pegasus.
  • Took a Level in Kindness: One of his first appearances had him getting in a very heated verbal fight with Sam over what he perceived to be a pointless search for a missing Colonel O'Neill. Pretty much the rest of his appearances had him as a Nice Guy.

    Dr. Robert Rothman
Played By: Jason Schombing
First Appearance: "Forever in a Day"

An archaeologist who existed mostly to fill a spot on the team whenever Daniel was incapacitated. Didn't get along with the military or people in general, though he seemed to be fairly good friends with Daniel. Unceremoniously killed off in his third episode after he was infested by a Goa'uld symbiote.


  • And Then John Was a Zombie: Gets taken over by a symbiote when he joins the team for a rescue mission on the primordial Goa'uld homeworld.
  • Captain Obvious: When asked to examine the crystal skull that sends Daniel out of phase for a while:
    Rothman: ...It's a crystal skull.
    Hammond: We knew that, Doctor.
  • Forgotten Fallen Friend: Apparently a good friend of Daniel's, but don't expect to hear him mentioned after his death.
  • The Load: He slows the team up with both his lack of experience and his constant complaining when he joins them in the field.
  • Mauve Shirt: Killed off with little fanfare in his third appearance.
  • Not Good with People: By his own admission. He claims they're "too recent" and he prefers fossils.
  • Omnidisciplinary Scientist: A minor example that seems to arise from the writers not knowing the difference between archaeology and paleontology. In his first few episodes it's implied he works in a similar field to Daniel, but he later claims to be an expert on fossils.
  • Real After All: His first appearance turns out to be part of a dream sequence, but he shows up in the real world a few episodes later.
  • Replacement Flat Character: All three of his episodes have him assisting the team on a temporary basis while Daniel is out of commission and highlighting the fact that he no longer fits the same "inexperienced scientist" mold as Rothman.

    Dr. Jay Felger
Played By: Patrick McKenna
First Appearance: "The Other Guys"

A largely incompetent scientist who hero-worshipped SG-1, to their great annoyance. Only appeared in two episodes, but they were among the most memorable of the show's comedic offerings.


  • Action Survivor: He has zero combat experience and it shows, but he does manage to zat at least one Jaffa. Just the fact that he survives is impressive in his own right.
  • All Up to You: Humorously subverted in his first appearance. He decides it's up to him and another scientist to "rescue" SG-1 after seeing them apparently being captured, but O'Neill reveals that they deliberately allowed themselves to be taken in order to liaise with a Tok'ra spy.
  • Bunny-Ears Lawyer: Lampshaded by Carter, who persuades Hammond to give him another chance by pointing out that for all his many, many flaws, the SGC wouldn't have hired him if he wasn't a brilliant scientist.
  • Butt-Monkey: If something he's working on can go wrong, it more than likely will.
  • Geek Physiques: The skinny sort.
  • Hero-Worshipper: Towards SG-1, something they're not particularly thrilled by.
  • Hollywood Nerd: Apparently he's not very successful with women, which is rather hard to believe given the attractiveness of the actor playing him.
  • Lower-Deck Episode: Both of the episodes he appears in feature him as the central character. In his second appearance, Carter is the only member of the team to get her usual amount of screentime.
  • Nice Job Breaking It, Hero!: Sends a computer virus to a planet ruled by Ba'al in the hopes out putting his Stargate out of commission, only for Ba'al to modify the program and disable the entire gate network.
  • Oblivious to Love: He's totally clueless about the fact that his assistant is totally enamored until she decides to plant one on him.
  • Plucky Comic Relief: Invariably plays this role whenever he shows up.
  • Those Two Guys: In his first appearence he was paired up with another scientist named Coombs and formed something of a comedy double-act with him.

Battlecruiser Crew Members

    Major Kevin Marks
First Appearance: "Avalon, Part 1"

Senior officer aboard the Prometheus, and later the Odyssey. Served a similar role to Walter, only IN SPACE!. Never a major player, but notable for serving on every American owned battlecruiser at least once and being one of only eight characters to appear in all three series.


  • Ascended Extra: He has a more prominent role in Ark of Truth than any of his previous appearances in the series itself.
  • Back-to-Back Badasses: With Carter vs. the Replicators in Ark of Truth.
  • Bridge Bunnies: A male version. He always seems to be hanging around whatever ship the team is currently using and his role largely consists of sitting at the bridge and announcing whatever it's doing.
  • The Comically Serious: Like Walter, he takes his job pretty seriously, and his reactions to the antics of the team are sometimes fairly amusing.
  • Rank Up: Twice in the space of one year; first from lieutenant to captain, and then to major.
  • Running Gag: His complete bewilderment whenever one of the team assumes command of the ship and starts channeling Trek.
  • Took a Level in Badass: Not generally very combat-oriented, but he picks up a P90 to help Carter fight the Replicator hordes in Ark of Truth.
  • What, Exactly, Is His Job?: It's never made entirely clear what his exact role is supposed to be. There are some episodes where he seems to be the weapons officer, but others imply he's the pilot or navigations.

    Colonel Lionel Pendergast
Played By: Barclay Hope
First Appearance: "New Order, Part 2"

Commander of the Prometheus. Became something of an Ensemble Dark Horse until he made a Heroic Sacrifice and got blown up along with his ship in "Ethon"


  • The Captain: Fits the trope due to his role as commander of the Prometheus, though his rank is colonel.
  • Danger Deadpan: Always speaks in calm, measured tones even when all manner of shit is going down.
  • Going Down with the Ship: He stays behind to ensure the crew are beamed safely to a nearby planet when the Prometheus is destroyed.
  • Killed Off for Real: In "Ethon"
  • Mauve Shirt: Never got a huge amount of characterization before his death, despite appearing in quite a few episodes.
  • Sacrificial Lion: His death and the loss of Prometheus towards the end of season 9 largely serve to demonstrate the seriousness of the Ori threat.

    Colonel Paul Emerson
Played By: Matthew Glave
First Appearance: "Off the Grid"

Commander of the Odyssey. Served pretty much the exact same role as Pendergast, and met a similarly sticky end (though his ship survived).



How well does it match the trope?
