Battle of the Second Overmind (To Slay the Beast)

The Battle of the Second Overmind marked the end of the United Earth Directorate supremacy over the Koprulu Sector, with Kerrigan rising as the new predominant power.

History
Kerrigan traveled to Char with the Matriarch Raszagal as her prize, with the purpose of finally defeating the United Earth Directorate and slaying the second Overmind with her secret weapon. Duran reminded her that the Overmind could only be killed by Dark Templar attacks, but Kerrigan said her "secret weapon" would arrive on time. Duran said he still did not understand, when he received a transmission from an unidentified protoss carrier.

Zeratul was commanding the carrier, and demanded to know why Kerrigan had stolen the Matriarch. Kerrigan was actually more interested in Zeratul. She needed him and his brethren to slay the Overmind for her. In return, she would allow the Matriarch to return to her people. Zeratul was suspicious, but Matriarch Raszagal appeared, telling him that the Overmind is their common enemy, and he must destroy it on behalf of their people. Zeratul reluctantly agreed.

Kerrigan's initial forces on Char were accompanied by a small number of Dark Templar and gateways to summon more. A huge battle erupted, as the United Earth Directorate defended itself with the aid of its captive zerg.

Eventually, Kerrigan's forces and the Dark Templar cleared away the Overmind's defense forces, and Zeratul personally slew it. Zeratul then demanded the return of the Matriarch. Kerrigan asked the Matriarch if she wanted to return to Shakuras, but the Matriarch said no.

Zeratul was astounded. Matriarch Raszagal was clearly not herself. Kerrigan admitted that she had enslaved the Matriarch on Shakuras long before she met Zeratul there. The Matriarch had underestimated Kerrigan's psionic powers and fell under her control. She bragged that, by enslaving the Matriarch, she had been able to manipulate the protoss into doing her bidding.

Zeratul said "we shall see" and was transported away by an Arbiter. However, Raszagal was taken away by the recall rift as well.
