Kkallakku is a fictional character appearing in the Marvel Comics universe. He was created by Roy Thomas, Jean-Marc Lofficier, and Larry Alexander, and first appeared in Dr. Strange: Sorcerer Supreme #31 (July, 1991).
Kkallakku is a demon, one of the Fear Lords, who has clashed with Doctor Strange. He was summoned to the Halls of Fear to join the other Fear Lords in a plot to gain control of Earth. Kkallakku summoned a legion of Fear-Eaters that assaulted Manhattan. When Doctor Strange withdrew the collective fear of the victims and drew it into himself, the Fear-Eaters ignored Kkallakku's commands and followed Doctor Strange who trapped them in another dimension.
The Fear Lords later met to discuss the Serpent's attacks on Earth. Loki tricked them into a meeting to tell them about Nightmare's scheme to harvest the fear brought by the Serpent to become the new King of Fear, leading to a battle that resulted in a stalemate.
