Editing Zerg (section)

== Appearances ==
In ''[[StarCraft (video game)|StarCraft]]'', the Zerg are obsessed with the pursuit of genetic purity, and are the focus of the game's second episode. With the Xel'Naga&ndash;empowered Protoss targeted as the ultimate lifeform, the Zerg invade the Terran colonies in the Koprulu Sector to assimilate the Terrans' psionic potential and give the Zerg an edge over the Protoss. Through the actions of the Sons of Korhal, the Zerg are lured to the Confederate capital [[Koprulu Sector#Tarsonis|Tarsonis]], where they capture the psionic ghost agent [[Sarah Kerrigan]] and infest her. Returning to the Zerg base of operations on [[Koprulu Sector#Char|Char]], the Zerg are attacked by the dark templar [[Zeratul]], who accidentally gives the location of the Protoss homeworld [[Koprulu Sector#Aiur|Aiur]] to the Zerg Overmind. With victory in sight, the Overmind launches an invasion of Aiur and manifests itself on the planet. However, at the end of the game, the Protoss high templar [[Characters of StarCraft#Tassadar|Tassadar]] sacrifices himself to destroy the Overmind, leaving the Zerg to run rampant and leaderless across the planet.<ref name="Story1">{{cite web|url=http://eu.starcraft2.com/features/storysofar.xml|title=The Story So Far: Part 1:''StarCraft''|publisher=[[Blizzard Entertainment]]|date=2007-11-21|access-date=2007-11-22|archive-date=2007-11-23|archive-url=https://web.archive.org/web/20071123100044/http://eu.starcraft2.com/features/storysofar.xml|url-status=live}}</ref>

The Zerg return in ''[[StarCraft: Brood War|Brood War]]'' initially as uncontrolled indiscriminate killers without the will of the Overmind to guide them. Through the early portions of ''Brood War'', Sarah Kerrigan is at odds with the surviving cerebrates, who have formed a new Overmind to restore control of the Swarm. Through allying herself with the Protoss, Kerrigan strikes at the cerebrates, causing disruption of their plans. Eventually, the UED fleet takes control of Char and pacifies the new Overmind with drugs, putting the cerebrates and most of the Zerg under their control. Kerrigan retaliates by forming a tenuous alliance with the remnants of the Dominion and the forces of [[Jim Raynor]] and [[Characters of StarCraft#Fenix|Fenix]], their subsequent victories turning the tide against the UED. However, she later betrays the alliance by dealing long-term damage to the infrastructures of her allies and killing Fenix. Proceeding to blackmail Zeratul into killing the new Overmind, Kerrigan's forces destroy the remnants of the UED fleet, giving her full control of the Zerg and establishing the Swarm as the most powerful faction in the sector.<ref name="Story2">{{cite web|url=http://eu.starcraft2.com/features/storysofar2.xml|title=The Story So Far: Part 2: The Brood War|publisher=[[Blizzard Entertainment]]|date=2008-04-16|access-date=2008-04-16|archive-date=2008-04-20|archive-url=https://web.archive.org/web/20080420022824/http://eu.starcraft2.com/features/storysofar2.xml|url-status=live}}</ref>

In ''[[StarCraft II: Wings of Liberty]]'', Jim Raynor and the rebel forces who oppose both the Dominion and the Zerg, manage to secure an ancient Xel'Naga artifact and after successfully infiltrating Char, they use it to subjugate the Zerg and restore Kerrigan's human form. Once again without a unified leadership, the Zerg get divided into multiple broods feuding over control of the Swarm. This situation persists until the events of ''[[StarCraft II: Heart of the Swarm]]''.  Kerrigan, believing Raynor to have been killed in a Dominion surprise attack, enters the original Zerg spawning pool to become the Queen of Blades again. This time she is no longer motivated to destroy humanity, having kept more of her original mindset due to the non-interference of the Zerg Hive Mind, and by extension, the Dark Voice, Amon.

Kerrigan is the protagonist and player character of StarCraft II: Heart of the Swarm. After being deinfested, she was taken in Valerian Mengsk's hideout to research on her, until the Dominion attacks the facility, she escaped along with the rest of the facility, except Raynor, who was captured by Nova. She later learned that Raynor was executed and seeks revenge on Arcturus. As she enters a Leviathan, she controls the local Swarm inside, and starts rebuilding her forces from scratch. She later evolved into a Primal Zerg after a confrontation with Zeratul, leading her to the origins of the Zerg. She became a Primal, after absorbing the spawning pool and killing Primal Leaders to collect essence. With her newfound power, she initially takes the fight to the Dominion after subduing countless Queens. She was later shocked after she knows that Raynor survived and held by Dominion as a bargaining chip. She organizes a raid, rescuing Raynor but the man fell into disbelief that the one he saved, returns to being a monster. She also confronted an ancient Shapeshifter creating Hybrids at the behest of her former rival named Alexei Stukov. She later prepared to end Arcturus Mengsk's reign by killing him in his palace in Korhal. She later left to confront the Shapeshifter's master and only by allied effort, they finished them. Kerrigan left them to her Broodmother Zagara's control.
