Zat'nik'tel, is a handheld weapon used by the Goa'uld. 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.

One shot will incapacitate a victim and cause immense pain. A second shot will kill them. 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.
