As Sasquatch, Langkowski possessed abnormal strength and stamina, as well as resistance to injury (in an early appearance, he fought the Hulk for "fun" in order to test his limits). He is strong enough to pull a naval destroyer ashore for repairs, as well as hold a DC-10 cargo plane against the thrust of its engines and then hurl it over 1,000 feet backward. Thanks to his thick fur, he can survive easily in extreme arctic environments. Sasquatch is able to jump vast distances, but not as well as the Hulk. His claws are sharp and durable enough to cut through stone, wood, and even some metals. Though his human body requires corrective lenses, Langkowski's vision as Sasquatch was better than human. He also heals with unnatural speed, as demonstrated when Walt's arm, broken by Super-Skrull, healed when he changed into Sasquatch.
