During the 2011 "Fear Itself" storyline, the Hulk finds one of the Serpent's magical hammers associated with the Worthy and becomes Nul: Breaker of Worlds. As he starts to transform, the Hulk tells the Red She-Hulk to run far away from him. Rampaging through South and Central America, Nul was eventually transported to New York City where he began battling Thor, with aid of the Thing, who was transformed into Angrir: Breaker of Souls. After defeating the Thing, Thor stated that he never could beat the Hulk, and instead removed him from the battle by launching him into Earth orbit, after which Thor collapsed from exhaustion. Landing in Romania, Nul immediately began heading for the base of the vampire-king Dracula. Opposed by Dracula's forces, including a legion of monsters, Nul was seemingly unstoppable. Only after the intervention of Raizo Kodo's Forgiven was Nul briefly slowed. Ultimately, Nul makes his way to Dracula's castle where the timely arrival of Kodo and Forgiven member Inka, disguised as Betty Ross, is able to throw off the effects of the Nul possession. Throwing aside the hammer, the Hulk regains control, and promptly leaves upon realizing "Betty's" true nature.
