Gorgom



Gorgom (ゴルゴム) is a fictional cult and criminal group who act as the antagonists in the 1987 Kamen Rider Series Kamen Rider BLACK. The group is notorious for its terrorist activities in the name of world domination and racial superiority over humanity.

Fictional history
For many years, Gorgom has been ruled by the mysterious Creation King. As Gorgom tradition dictates, a new King must be chosen every fifty millennia. The selection process involves finding several worthy candidates who will be transformed into mutants deemed Century Kings (世紀王), sentenced to fight for the crown with the survivor becoming the new Creation King.

In 1987, Gorgom has chosen Kotaro Minami and Nobuhiko Akizuki for this purpose. During their surgery, the previous Creation King commanded the High Priests to place the powerful Holy Kingstones into their bodies. Kotaro was implanted with the "Sun's Stone", and was given the name Black Sun. However, Soichiro Akizuki, the boys' father, went again Gorgom and died freeing Kotaro from being the final stages of his surgery, Nobuhiko, on the otherwand, recieved the "Moon's Stone", placed into supended animation before emerging as "Shadow Moon."

When Shadow Moon caused the apparent death of BLACK, it affected Japan with some of them leaving the country and some worshiping the organization. With BLACK's revival, he finally confronts Shadow Moon and the Creation King, ending Gorgom as a result of the latter's death while the former survived.

Creation King
The Creation King (創世王) is the almost omnipotent leader of Gorgom. He appears as a giant evil heart that communicates with the High Priests and the two Century Kings via telepathy. The Creation King also had monstrous strength that could destroy the entire universe. The Creation King pulled Kamen Rider BLACK away from where the Stickleback Mutant was attacking Whale Mutant. He made itself known to Kamen Rider BLACK and Shadow Moon. The Creation King then transported BLACK and Shadow Moon to the battle field to determine who will become his successor. After Shadow Moon was ultimately defeated, BLACK confronted the Creation King who threatened him to take the Kingstone from Shadow Moon's body unless he wants the Creation King to jump into the hole he created to lead him to the Earth's core and destroy it from within. The Creation King was killed by BLACK when the Satan Saber was stabbed into him.

High Priests
The Three High Priests (三大神官) are second only to the Creation King, and they carry out his will. Upon their sacrificing their Stones to revive Shadow Moon, the dying High Priests undergo a transformation into new physical forms called the Grand Mutants (大怪人), reborn as Shadow Moon's emmissaries. Setting up for his final battle with Kotaro, Shadow Moon sends the Grand Mutants to attack the city, overpowering the police as everyone runs out of Tokyo.
