Any elite fighter in Vinland Saga is ultimately measured against Thorkell the Tall. The giant represents the apex of physical destruction in the setting, a man who cleaves cavalry horses in half and throws tree trunks like javelins. When Garm crosses paths with Thorkell during the Baltic Sea War, the resulting encounter redefines the comic’s power hierarchy.
Where lesser men panic against Thorkell's terrifying size, Garm treats him like a giant toy. His footwork is fast enough to evade Thorkell’s lumbering downward chops. Rather than trading blows directly, Garm dances outside the giant's peripheral field, landing precise thrusts that slice Thorkell’s ear and pierce his thick hide without taking a crushing strike in return.
While Thorkell possesses the crushing power to end Garm with a single clean grapple, Garm’s combat agility exposes the giant's turning radius. The battle demonstrates that Garm belongs in the absolute highest tier of combat efficiency in the manga canon, matching the lethal threat of historical commanders through sheer kinetic speed.
