Kha'ak

The Kha'ak are a fictional insectoid alien race in the X computer game series developed by Egosoft. Not much is known about their culture, biology, technology or motives. They first appeared in X2: The Threat where they started jumping into sectors by using a gateless jumpdrive and attacking ships and installations. In their largest victory, the Argon Federation sector Presidents End was decimated, leaving wrecks of stations behind. In their next attack, the Kha’ak used a M0 Planet Destroyer to try and destroy the central planet in the Argon sector, Omicron Lyrae. This plan was thwarted by Julian Brennan, Saya Kho, Bret Sera and Allied forces. There has been no communication from the Kha'ak.

They were still attacking the X Universe in X3: Reunion

Technology
The Kha'ak appear to be highly advanced as they have created jumpdrives which do not require a gate at the exit. This allows them to attack practically anywhere in a sector. The Terrans have created a similar advanced jumpdrive except their version was far from reliable. The Kha’ak version appears to be capable of moving vast fleets into a single chosen sector at the same time with no damage to their systems. The Kha’ak also have a M0 class planet destroyer which was used in the attack of Omicron Lyrae. Only the Xenon (X) have an equivalent ship, although this may be due to the commonwealth of planets not needing such a weapon.

Ships
The Kha'ak usualy jump into a sector using a cluster of ships. These are usually composed of one Kha’ak Fighter and several Kha’ak Scouts. These are classed as M3 Fighters although they have no active weapons. Due to this configuration, M4 Interceptors are rarely seen in attacked sectors. The M0 planet destroyer appears as a non flyable plot object in X2: The Threat.
