Only known energy weapon capable of disabling a Kull warrior, Anubis's genetically-engineered super-soldier. The technology may be mounted on a number of different projectile weapons, including a Goa'uld transphase eradication rod (T.E.R., used as a prototype for the Kull disruptor) and an Earth-made P-90. In some cases, such as that of the P-90, the user may fire both standard rounds and the blue Kull disruptor blasts simultaneously. The disruptor modification can be recognized by the presence of a multi-color, oscillating light on the device.
The disruptor technology is based on the same Ancient healing device that the Goa'uld used to animate the super-soldiers. Daniel Jackson and Bill Lee located the original Ancient device in Central America, allowing Earth and the Tok'ra to develop the disruptor weapon. The project was led by Jacob and Samantha Carter, who were barely able to complete the new technology before the Kull warriors stormed the research lab.
The prototype weapon was only partially effective, usually requiring at least two shots to bring down one of the super-soldiers.
