Thor Annual #9, Newsstand Marvel, 1981

Thor King-Size Annual #9 (1981) pits Thor and Umar as pawns in a deadly, chessboard-like contest between All-Father Odin and the dread Dormammu, delivering a surreal, magic-heavy storyline rather than a straight action tale. The oversized annual features mystical confrontations, Odin’s manipulations and Dormammu’s dark sorcery, with Umar playing a key role. A classic early ’80s Thor annual that spotlights supernatural stakes and cosmic intrigue.
