"Vengeance" is the nineteenth episode of the third season of Stargate: Atlantis.


The Taranians have failed to contact Atlantis, so Lt. Colonel John Sheppard's team is sent to investigate. They find the settlement abandoned, and soon find them all dead, by Michael Kenmore's experimenting.

Previously on Stargate: AtlantisEdit

On a mission to the Wraith homeworld, Major John Sheppard is attacked by an Iratus bug. A year later, the team meets Ellia, a female Wraith that was raised by a Human named Zaddik. Ellia takes Dr. Carson Beckett's incomplete Iratus bug retrovirus and turns into a creature closer to an Iratus bug. Sheppard and Ronon Dex manage to kill her but she feeds on Sheppard's arm and he is infected with the retrovirus and transforms into a creature similar to Ellia.



Taranian settlement

Dr. Elizabeth Weir reports that the Taranians haven't contacted Atlantis in over two months. Lt. Colonel John Sheppard's team is sent to look for them. On the Taranian settlement they discover it appears as though the whole settlement has been abandoned.

Detecting a life sign below them, the team searches an underground complex made by the people who lived there before the Taranians. There they are faced with a large creature which has similarities with the Iratus bug, after finding a room full of dead Taranians, an Iratus bug in a jar full of liquid and a large cocoon/pod in an empty room.

After a scheduled check in, and before the team comes into contact with the life sign, Weir sends them a Marine contingent to help them deal with the creature, but soon after they arrive they are abducted by a Wraith Dart.

After Sheppard's team has little luck with destroying the creature (Ronon Dex only manages to cut off its arm) and realizes they've lost contact with the Marines, they try to return to Atlantis, only to find that the control crystals have been removed from the Dial Home Device, disabling the Stargate. Returning to the complex they discover that Michael Kenmore, after being rejected by the Wraith began experimenting with the bug and created these creatures to take over the galaxy. They soon discover that he has hundreds of those creatures on that planet and this is not the only planet on which he is breeding them.


Ronon Dex is surrounded by Bug People.

While Dr. Rodney McKay and Teyla Emmagan stay in Michael's lab, McKay tries to figure out what Michael was doing and how many creatures are on the planet. Meanwhile, Sheppard and Ronon use the air vents to get to the surface and locate the control crystals. Unable to find the control crystals and with the creatures on their tail, they quickly find Michael's Wraith Dart. Sheppard is able to fly it and then beam Ronon, Teyla, and McKay on it and then use its DHD to dial out.

Daedalus is redirected to go and nuke the planet but when they arrive there they find that the whole place is wiped clean with no sign of Michael or the creatures.

At the very end of the episode, Weir explains to Teyla that it was their fault the Taranians were killed, as the Wraith discovered their location after they hacked the Atlantis database during their alliance. Weir also mentions that according to what McKay was able to decipher from Michael's device, there are at least three other planets where Michael was conducting his experiment and there are hundreds of beasts out there.

Notable QuotesEdit

(Ronon is teaching Rodney how to fight.)
Ronon: Eyes straight ahead, focus on me. Never ever look away from your enemy. Shows weakness. Are you weak?
(Rodney is dressed in ninja/martial arts clothes and holding a stick)
McKay: Ah... no.
Ronon: Good. Are you ready?
McKay: Ah...
Ronon: Urgh!
(Ronon hits Rodney in the stomach with his stick. Rodney bends over in pain)
Ronon: McKay, what did I say? Don't take your eyes off of me. You gotta anticipate their next move. (Rodney is still in pain) You all right?
McKay: Mmm.
Ronon: All right, well I'll try to ease up so I don't hurt ya. You're getting better.
McKay: Oh, really?
Ronon: No.
(Elizabeth and John come in)
Sheppard: How are the ninja lessons going, Jet Li?

(after the explosion)
Sheppard: Is everyone OK?
Teyla: Yes.
Ronon: Yeah, I'm good.
McKay: I think you singed my eyebrows. Think you used enough dynamite there, Butch?

Sheppard: Did anybody get a good look of that thing?
McKay: Aside from its severed appendage, no that thing moved incredibly fast.
Ronon: In some ways it looked almost like a human.
McKay: If by human you mean clad in a grotesquely proportionate exoskeleton, yes, very human.

Sheppard: Alien. (Pause) The movie Alien, they used the air shafts to move around the ship.
McKay: And then systematically killed the entire crew one by one. Thank you for bringing that up.
Sheppard: They didn't kill 'em all.

McKay: You would think that the human side of [Michael] would temper his aggression a bit.
Teyla: Yes, because we humans aren't aggressive at all.
McKay: Well, certainly less aggressive than the... oh, sarcasm! Yeah, nice.

(Sheppard and Ronon see a dart in the clearing)
Ronon: Michael's?
Sheppard: No doubt.
Ronon: You thinking what I'm thinking?
Sheppard: I fly it. Pick you, Rodney and Teyla up. We use the dart's DHD to dial the gate.
Ronon: I was saying blow it up, but your idea's better.

  • Near the end of the episode, when Atlantis receives an incoming wormhole, Chuck announces that they are receiving Lt. Colonel John Sheppard's IDC, though it is obvious that the Stargate has not actually opened yet, and is still being dialed in.
  • As they search the tunnels, an EXIT sign can be seen briefly. Although most civilizations in the Stargate universe speak English, none have developed anything similar to the Latin alphabet.
  • As they are walking back to the Stargate and discussing wraith reproduction, you can clearly see Ronon waving at someone off screen.
  • Crediting Connor Trinneer in the opening credits gives away that it is Micheal behind the experiment.
