Pedro Peña along with his five friends Billy Batson, Eugene Choi, Darla Dudley, Freddy Freeman, Mary Batson, and pet cat Tawky Tawny were trapped in a subway car that transported them to the Rock of Eternity. There they met the wizard Shazam who granted each of the children with a different one of the wizard's attributes. Pedro Pẽna, due to his size and presence in the group, was given the strength of Hercules.
