Jem'Hadar

The Jem'Hadar are a sentient species in the Original Universe.

History
In 150,080 CMT, Blackout used the Architect's computer to create a gigantic amalgam fleet of alien ships with which to attack his enemies. D-Klak identified some of the ships as belonging to the Jem'Hadar. The fleet, which Blackout had programmed to be loyal to him regardless of prior affiliation, was then used to attack his enemies in the Battle of BZPower.
