The team learns that a rogue Wraith has acquired several Z.P.M.s to power a formidable new hive ship — and he is headed for Earth.

“Enemy At the Gate” Facts:

• The series finale marks the 100th episode of Stargate Atlantis.
• Colin Cunningham appeared in some 15 episodes of Stargate SG-1, as Major Paul Davis. When he turns up here in the midst of the impending Wraith attack on Earth, it’s his one and only appearance on Stargate Atlantis.
• We’ve seen Wraith drain human victims to the brink of death, and then restore their life and youth again (“Common Ground”) — but this episode is the first time we see someone pretty much dead (Ronon) who is resurrected by a Wraith’s ability. It added an interesting wrinkle in a potential alliance with Todd, had the series continued.
• Colonel Caldwell mentions in passing that the Earth cruiser Odyssey is off on a super-secret mission. Producers eventually confirmed that this was an oblique set-up for Stargate Universe: the Odyssey crew was searching for a naquadria-rich planet capable of supporting the Icarus Project and the plan to dial the 9-chevron address.
• Despite the fact that “Enemy At the Gate” wasn’t intended to be the show’s final episode, thematically the return to Earth makes for a nice bookend to the series. The Ancient city hasn’t sat on the surface of the Earth since the first scene of the first episode (“Rising, Part 1”).
• Though SGA was cancelled in 2008, Syfy Channel quickly announced that it planned to air a direct-to-DVD movie — potentially the first of an ongoing series of movies. But eventually, when the DVD market continued to soften and MGM plunged into bankruptcy, all plans for Stargate: Extinction and future films were shelved indefinitely.
