General Mills teamed up with Warner Bros. Pictures for the theatrical release of BATMAN V SUPERMAN: DAWN OF JUSTICE with character-inspired products. Inside the specially marked boxes of Honey Nut Cheerios, Lucky Charms, Cocoa Puffs, Trix and Golden Grahams, consumers were able to find one of four exclusive comic books. General Mills also released two limited edition cereal boxes, “Superman Caramel Crunch” and “Batman Chocolate Strawberry.” Superman Caramel Crunch pieces were shaped like the Superman shield and Batman Chocolate Strawberry were modeled after the Batman emblem.
