The immobilizer pulse is a weapon used to disable spacefaring vessels rather than to destroy them. This is particularly useful on Pantak-class Vigilantes that are used to track down and capture spaceships on the behalf of the Peacekeepers.
Although immobilizer pulses are designed to disable ships, they are extremely damaging to biomechanical spaceships like Leviathan biomechanoids. Use of such a pulse on a living ship will cause incredible pain, and any sentient beings bonded to the vessel will be rendered utterly incapacitated as well as a result.
Immobilizer pulses are derived from Farscape.
