King kong
There were two King Kongs in Battle World, the original Black and White one, who was in the Cosmic Graveyard, and the Peter Jackson remake. The original was sent to the Cosmic Graveyard by Dr. Loboto

The Remake version, who appears in Battle World, was a fairly minor character. It is known he was a mortal enemy of Kitten Kong, who came near destroying him, however, he was saved by Ultraman.
