Pig-Iron was a member of the Zoo Crew.
Peter Porkchops was an anthropomorphic pig operating out of Piggsburgh, Pennsylvania in the parallel reality known as Earth-C. Early in life, Peter was a hobo who frequently matched wits with his neighbor A. Wolf, who alternately wished to ruin Peter's day or simply eat him. Peter eventually got a job working in a steel mill.
Several years ago in the Earth-One reality, the galactic conqueror known as Starro launched a de-evolving ray towards the planet Earth. The energy beam interacted with a meteor which Superman pushed through a barrier that inadvertently brought him to the Earth-C dimension. The meteor shattered and pieces of it landed across the United Species of America affecting several different individuals. Peter Porkchops was working in the steel mill one day when he was exposed to radiation from a meteor fragment. The exposure gave him superhuman strength, stamina and durability. Calling himself Pig-Iron (after the smelted ore process), he soon joined up with several more similarly affected creatures and became a member of the Zoo Crew.
Perpetual Hunger: Pig-Iron suffers from a virtually unceasing appetite and is known to consume just about anything. No matter food stuffs he eats, Peter is always hungry.
- This version of Pig-Iron, including all history and corresponding appearances, was erased from existence following the collapse of the original Multiverse in the 1985–86 Crisis on Infinite Earths limited series. Even though versions of the character may have since appeared, this information does not apply to those versions.
- In Peter Porkchops #30, Peter's hometown is given as Zooville. Years later in Captain Carrot, he resides in the city of Piggsburgh. Perhaps he moved in the 30-odd years between.
- Peter Porkchops is the only member of the Zoo Crew who was introduced during the Golden Age era.
- In Captain Carrot and His Amazing Zoo Crew #9, Alley-Kat-Abra estimates Pig-Iron's weight in 2,817 pounds, far more than the official 256 pounds given in Who's Who: The Definitive Directory of the DC Universe #18.
