The Battle over Char (sometimes also generally known as the Battle of Omega, Omega Battle or the Battle of Char Aleph) was the largest and most important engagement of the Brood War, where the outcome of the war was to be finally decided. Fought between a conglomerate of a Dominion fleet, the UED remaining fleet and the protoss fleet against Kerrigan's Zerg Swarm on the space platform Char Aleph in high orbit over the planet Char, it signified the end of all UED major resistance in the sector, as well as a serious decline for both Dominion and protoss military capabilities, ensuing in the ascension of Sarah Kerrigan, the self-proclaimed Queen of Blades, as the undisputed ruler of the zerg swarms on the Koprulu Sector.
