Major and recurring characters from the military science fiction series StarCraft are listed below, organised by respective species and most commonly affiliated faction within the fictional universe. The story of the StarCraft series revolves around interstellar affairs in a distant sector of the galaxy, where three species are vying for supremacy: the Terrans, a highly factionalised future version of humanity; the Protoss, a theocratic race of vast psionic ability; and the Zerg, an insectoid species commanded by a hive mind persona. The latter two of these species were genetically engineered by the Xel'Naga, a fourth species believed extinct. The series was begun with Blizzard Entertainment's 1998 video game StarCraft, and has been expanded with sequels Insurrection, Retribution, Brood War, Ghost, Wings of Liberty, Heart of the Swarm, and Legacy of the Void. The franchise has been further extended with a series of novels, graphic novels, and other works.
