It appears to have a water buffalo like head with weird looking horns, four stumpy legs, and a turtle like shell on the top of its back. Although the rondors were one of the dangerous animals of Krypton, Jor-El has kept some of them in the garden outside of the House of El Citadel. They were soon extinct along with many other lifeforms following the destruction of Krypton.
