Juggernaut is able to generate a mystical force field that grants him additional invulnerability to any physical attack when it is at its maximum. Even when the force field is temporarily absorbed by Thor's hammer, the Juggernaut's natural durability still proves to be great enough to withstand blows from Thor. The Juggernaut is described as physically unstoppable once in motion, does not tire from physical activity, and is able to survive without food, water, or oxygen. The Juggernaut heals quickly, as when he was stabbed through the eyes by Shatterstar, the wounds were healed almost immediately.
