"This is a Goa'uld Zat'nik'tel. A weapon using a different form of energy, less powerful than that of a staff weapon. Less destructive, but still quite deadly."

The Zat'nik'tel, also known as a Zat or Zat gun, is a Goa'uld handheld energy weapon. It is one of the most common weapons utilized by the Jaffa and Tok'ra, being easy to conceal and extremely lethal. They are known to have been in use by the reign of the System Lords for at least five thousand years. (SG1: "Seth", "Moebius, Part 1", "Moebius, Part 2")


"The Goa'uld take great pleasure in discharging the weapon only once on a subject. Causing great pain, disabling them, but not killing them. The second shot will kill most subjects."

Visually, the Zat'nik'tel's design resembles a Goa'uld symbiote. The weapon is activated by squeezing a switch on the bottom curve of the gun. Following this initial activation, each subsequent press fires a directed energy beam from the "mouth" of the goa'uld. When deactivated, the weapon becomes more-compact with the top section folding down several inches.

Zat'nik'tel 3

A zat being fired.

The Zat'nik'tel is unique in its operation compared to other weapons. One shot will incapacitate a victim and cause immense pain. A second shot will kill most subjects, but not all. A third shot will disintegrate the victim and their clothing. It will also disintegrate small inanimate objects with low densities, leaving no visible trace of their existence. These shots do not have to be fired consecutively as some individuals have been killed several minutes after the first Zat blast. However, an extended period of time between shots will cause the effect to wear off and two new shots will be necessary to kill. (SG1: "Within the Serpent's Grasp", "1969", "Point of View") In this intermediate period, the victim's body will possess a mild electrical charge which will gradually decrease within a matter of minutes. (SG1: "Prodigy")

Zat'nik'tel 4

The energy emitted from a zat resembles a sine wave bisected by a horizontal line.

The zat'nik'tel emits a translucent blue blast upon being fired. This blast resembles the shape of a quickly-oscillating sine wave bisected by a horizontal line. The blast travels in a straight line and leaves in its wake a trail several meters in length until it is ultimately absorbed by its target. If shot at either an individual or an inanimate object, the blast will engulf the entire body of the object in shimmering bands of energy that will persist for several seconds until it has been fully absorbed.

While a zat'nik'tel blast will not cause explosive damage, a single blast will generally short out most electrical devices with ease. When shot at a small fire, however, it will cause a rapid increase in flame-size for several seconds. (SG1: "1969") The blast of a zat'nik'tel is able to travel through conductive materials. As such, if fired at one end of a steel beam, the blast will travel the beam's length, emerging from the other side. (SG1: "Memento Mori")

Stargate Wiki has a collection of images related to Zat'nik'tel.
  • While it has been established that one shot from a Zat'nik'tel will stun an individual to the point of unconsciousness, there have been several instances where one shot merely causes the individual tremendous pain, leaving them fully conscious after the shot. However, in either case, a second shot will be fatal. It is unknown if this indicates that the power setting of the device can adjusted or if individuals who have been shot with a zat'nik'tel several times throughout their life are less susceptible to the first shot.
  • The "third shot" function of the Zat is only used four times ("Within the Serpent's Grasp", "Family", "Secrets" and "1969") in SG-1, all to disintegrate the bodies of Jaffa guards and material (to be removed from the timeline), and is mentioned one other time. Other "third shots" have been attempted, on replicators and Kull warriors, to no effect.
  • Some of the producers crew behind Stargate SG-1 believe that the third shot of a Zat is a bit of a deus ex machina and silly, as stated in several Stargate SG-1 DVD commentaries. The episode "Wormhole X-Treme!" comments on the effect, with director of the show-within-a-show calling the disintegration idea "the stupidest thing..."
  • Starting in later seasons, particularly seasons 9 and 10, SG-1 began using zats as their sidearms more often than pistols. This is likely due to a zat's known effectiveness and not being reliant on ammunition. They also used the one-shot function more often than shooting their enemy twice.
  • When fired, the zat props would actually slightly extend its tip.
  • In an interview, both Ben Browder and Michael Shanks admit they both disliked the zat.
    • Ben Browder says working with it is not as satisfying as using actual firearms, which could produce actions such as firing blank rounds and reloading while the zat prop could only move its tip.
    • Along with his distaste of the function of the zat's third shot, Michael Shanks addresses several other issues he has.
      • Having seemingly random abilities, such as it being able to open a locked chest by shooting it (SG1: "1969")
      • The uncertainty of the CGI crew knowing when the weapon was fired, citing a moment in Fallen when Corin Nemec can be seen making the firing motions with a zat but no special effects are added.
