"If this works, the same energy field that now protects the Atlantis gate from DV alien incursions will be amplified by the stargates themselves... Disintegrating every alien and piece of technology they brought with them from their home reality."
―Rodney McKay[src]

The McKay/Zelenka Attero Device is a disintegration field that connects directly to a Stargate's shield and disintegrates whatever passes through the event horizon. It was made specifically to combat the Unknown Alien threat.

Overview[edit | edit source]

Dr. Rodney McKay and Dr. Radek Zelenka created their device by modifying Janus' Attero device. The main difference being, instead of broadcasting into subspace itself like the original, theirs connects directly with the Stargate.

The device can also be attuned to work on specific things, such as the energy signature from the Alien's subspace domain. (SGA: "Gateways 3")

History[edit | edit source]

In 2009, the device was originally put to use in Atlantis' control room, with the intention of the Tau'ri to begin manufacturing more of the devices to give to the inhabitants of the Pegasus galaxy, in order to protect them from the Alien's invasion. (SGA: "Gateways 3")

However, instead of making one device per Stargate, Dr. McKay later came up with the idea to interface the device with the Stargate Network as a whole through the Stargate hub, using the Stargates themselves to amplify the energy field, disintegrating everything with the Alien's energy signature. This plan was successful. (SGA: "Singularity 2", "Singularity 3")
