Technology in Stargate - Wraith Technology

Wraith Technology

The Wraith are the main antagonists of Stargate Atlantis. Although not as advanced as their enemies, Ancients, the Wraith were able to drive them out of the Pegasus galaxy by virtue of superior numbers, made possible by cloning technology powered by stolen ZPMs. The Wraith have been shown to be tactically and technologically adaptable, being able to quickly develop a countermeasure to Asgard beaming technology, and creating highly sophisticated computer viruses for use against the Daedalus and the Asurans. The Wraith also operate an extensive network of transmitters and relay devices throughout Pegasus that allow them to respond rapidly to events of interest. Many pieces of Wraith technology, including their ships, are a hybrid of organic and mechanical parts with the ability to heal damage. Prominent Wraith technologies include:

• Culling beam A short-range transporter beam that dematerializes and stores matter for rematerialization at a later time. They are most often mounted on the bottom of Wraith darts for the purpose of capturing human prey, hence the common name. They can also be used to deploy troops, or as a site-to-site teleportation system in Wraith facilities.
• EM generator An experimental device that generates a low-frequency pulse capable of triggering traumatic hallucinations in nearby humans, meant to enhance the Wraith's telepathic ability to create illusions. Abandoned on a planet after it proved unstable, it is activated by a group of Genii, who kill each other under the device's influence. The Atlantis team nearly suffers the same fate.
• Grenade A spherical explosive device on a timer, activated by pulling the two hemispheres apart, twisting a quarter turn, and pushing back together. John Sheppard uses one as a landmine in an unsuccessful attempt to kill a Wraith in "The Defiant One". It should be noted that this grenade has a golden colour, an inorganic design and seems designed to kill rather than stun its targets. For these reasons it should be considered a possibility that the wraith from which the devices were recovered may have taken them from a victim, possibly a Lantean.
• Probe A hovering spherical device used for reconnaissance. One investigates M7G-677 in response to a location signal, and another monitors the hunt of Ronon Dex on Sateda. It has similarities with the "Kino" which was discovered by the Destiny Expedition in SGU.
• Stun bomb Newly introduced weapon shaped like a ball, that generates a massive stunner discharge. Its range is shown to cover the entire SGC facility.
• Stun rod A rod separated into two pieces that, once connected, generate a stunner discharge that incapacitates everyone within at least a dozen meters except for the user.
• Stunner Handheld weapons designed to incapacitate human prey for future feeding, and thus cause no significant physical damage. Three sizes of stunners have been shown: a small pistol, a medium truncheon, and a large rifle with a bayonet-type spike. Some humans are more resistant to stunner blasts than others, and humans under the influence of Wraith feeding enzyme are either immune or extremely tolerant to its effects. The Atlantis Expedition has accumulated a cache of stunners from their encounters with the Wraith.
• Subspace tracker An organic device that transmits a tracking signal through subspace, allowing targets to be tracked from many light-years away. Runners have these surgically implanted into their back, usually in or near their spinal columns, preventing easy removal and enabling the Wraith to easily keep track of them.
• Intergalactic Communication Device Constructed by a Wraith on Earth in a parallel universe. Used electricity from the main power grid of the US to send a message to other Wraith about the location of Earth. When activated, it also generates an enormous EM field that can cause blackouts miles away. Due to the immense power, the device also opened a small rift in the space-time continuum, carrying the message to other realities due to it being destroyed before the transmission was finished.
