Fear Itself: El libro del Cráneo

In 2011, Editorial Televisa published this single-issue tie-in to the larger Fear Itself event, written by Ed Brubaker with art by Scot Eaton. The story explores the mystical origins and power of the Serpent's hammers, focusing on the ancient tome known as the Book of the Skull. It serves as a crucial, standalone piece of the Marvel crossover, offering readers a deeper look into the mythology driving the global chaos.
