The most iconic Warcraft character. Once a paladin devoted to protecting his people, Arthas was consumed by his obsession with destroying the undead plague at any cost. He took up the cursed runeblade Frostmourne, sacrificed his soul, slaughtered his own men at Stratholme, and eventually drove a sword through his own father's heart. He became the Lich King's champion and later merged with him entirely. Defeated in WoW: Wrath of the Lich King.

Son of Durotan, raised as a slave gladiator by the human lord Aedelas Blackmoore, Thrall escaped and united the scattered orcish clans into a new Horde built on shamanistic traditions rather than demon blood. He founded Orgrimmar and led the Horde through the Third War. Later became the Earth Warden, channeling the elemental powers of the world itself. One of gaming's most complex "villain-turned-hero" arcs.

One of the most powerful mages in Azeroth, Jaina was instrumental in forging the temporary Alliance-Horde truce during the Third War. She was a voice for peace for much of WoW's history — until the Horde bombed her city of Theramore with a mana bomb, killing thousands. Her hair turned white from the blast. The loss hardened her into an implacable foe of the Horde and later forced her to reckon with her own capacity for hatred.

Night Elf twin brother of Malfurion. Illidan absorbed the powers of the Skull of Gul'dan and transformed into a demon-human hybrid to fight the Burning Legion — at the cost of being imprisoned for 10,000 years by his own people. "You are not prepared" became one of gaming's most quoted lines. In WoW: Legion, his sacrifice proved essential to defeating Sargeras, reframing him as an anti-hero who paid a price no one else would.

Former Ranger-General of Silvermoon, killed and raised as a banshee by Arthas during the fall of Quel'Thalas. She reclaimed her body, broke free of the Scourge, and founded the Forsaken — the free undead. As Warchief, she burned the Night Elf World Tree Teldrassil, killing thousands. In Shadowlands, it was revealed she had been manipulated by the Jailer for decades, adding tragic dimension to her villainy.

The greatest human warrior of the Second War, Lothar rallied the Alliance of Lordaeron after the fall of Stormwind. Descendant of Arathi kings and last of the Arathi bloodline, he was killed at Blackrock Mountain during the climactic battle of the Second War — betrayed by the orcish warlock Gul'dan's agents. He is honored by a statue at the Gates of Ironforge and is the namesake of Anduin Wrynn, WoW's boy-king.

Guardian of Tirisfal and the most powerful mage in Azeroth's history — possessed since birth by the spirit of the demon lord Sargeras. Medivh opened the Dark Portal that allowed the orcish Horde to invade Azeroth in the First War. He was killed by his own apprentice Khadgar and his childhood friend Anduin Lothar. Reborn as a spirit, he guided Jaina, Thrall, and Tyrande to Kalimdor to face the Legion in the Third War.

The orcish shaman who made a pact with the Burning Legion, corrupting his entire race with demon blood and forging the first fel-warlock traditions. He orchestrated the creation of the Dark Portal, the sacrifice of the draenei, and the formation of the Shadow Council. Abandoned by the Legion when he opened the Tomb of Sargeras, he was torn apart by demons. His skull became a weapon of mass destruction used multiple times throughout the lore.
