Birugenia (ビルゲニア Birugenia), Gorgom's warrior, made his first appearance in episode 18. He was born 30,000 years ago on a day of a solar eclipse, just like Kohtaro & Nobuhiko. However, a Kingstone was never given to him because the Creation King didn't favor him and therefore he could not become the next Creation King. This made him angrily trying to revolt against him and resulted with the Creation King sealing him in a coffin. The Creation King ordered the three High Priests to release Birugenia after they kept failing to retrieve the Kingstone from Kohtaro. He was both a pain for Kamen Rider Black as well as to Gorgom.
