Third Avatar
In the Fear Itself storyline, Juggernaut becomes Kuurth: Breaker of Stone (one of the Heralds of a long-dormant god of fear known as the Serpent) upon lifting one of the hammers that fell towards the Raft. Colossus makes a bargain with Cyttorak to gain the power to stand against Kuurth. Colossus becomes the new avatar of the Juggernaut and is able to push Cain Marko back until Cain is summoned by The Serpent.
