Kel'Thuzad is a major character from Blizzard's Warcraft universe, first introduced in Warcraft III as a human necromancer who later returns as a powerful lich serving the Lich King. He went on to become a memorable raid boss in World of Warcraft, where his cold, sardonic presence made him a favourite among players. As Warcraft clips spread through YouTube, Twitch and meme edits, his voice lines became shorthand for sinister scheming and undead menace, and creators still reach for them whenever a scene needs a villain who sounds ancient, patient and dangerously amused.
