More Info: When Cain Marko found the Gem of the mystical entity Cyttorak, he was empowered with magical energies and transformed into an immortal avatar for the entity in question. As the Juggernaut, Marko possesses superhuman strength, being capable of shattering mountains, lifting and using buildings as weapons, and extreme durability. His durability is amplified by a mystical force field that grants him additional invulnerability to any physical attack (at its maximum). Even when the force field was temporarily absorbed by Thor's hammer, the Juggernaut's natural durability still proved 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. It is possible for an opponent with sufficient physical or mystical strength of their own to turn the Juggernaut's unstoppable movement against him, by redirecting his motion so he gets stranded in a position in which he has no escape; both the Hulk and his son, Skaar, have managed this feat physically, and Thor has managed this feat mystically with Mjolnir. The only character to have stopped Juggernaut while he was in motion as an act of pure physical strength was the Hulk while he was War, a horseman of Apocalypse. When he has gained complete access to the Gem's powers during the Trion saga, it increased his power a thousandfold. Trion Juggernaut was capable of altering the size of matter, growing in size, tracking, levitation, absorbing energy, projecting energy, increasing his own strength, and creating portals through space-time. The character is vulnerable to mental attacks, a weakness that has been exploited via the removal of his helmet, which normally protects him from such. The Juggernaut has circumvented this weakness on occasion by wearing a metal skullcap inside his main helmet. If Juggernaut loses his helmet he can magically recreate it from available raw materials (as long as he possesses the full power of the gem).
