During the "Fear Itself" storyline, one of the seven Hammers of the Worthy that was launched to Earth by Serpent: God of Fear lands near Juggernaut. Juggernaut lifts it and becomes Kuurth: Breaker of Stone. His transformation is enough to level the Raft, causing a mass prison break. Kuurth makes his way to California and fights the X-Men. Magik, Colossus, and Shadowcat go to Cyttorak's dimension and inform it that the Serpent has control over Juggernaut. Magik strikes a deal with Cyttorak, who chooses her to become the new host of the Juggernaut's powers. However, the entity transfers the Juggernaut's powers to Colossus instead. Colossus is able to turn the tide on Kuurth before Kuurth is teleported away by the Serpent. During the last battle between the Avengers and the Worthy, Kuurth is defeated by Wolverine using his Uru armor and loses his hammer when the Serpent is killed by Thor.
