After the rebellion of Black Sun and before the awakening of Shadow Moon the orders of Creation King were carried out by three priests of Gorgom, Daraomu (episodes 1-49), Baraomu (1-46), Bishumu (1-44) and the warrior Birugenia (18-35).
Daraomu (Shoji Hirokazu) was the senior of the three Gorgom priests. He could manipulate people (slamming them against walls for example) and objects by simply pointing at them. He used rays from his hands to perform cybernetic surgery.
Baraomu (Takahashi Toshimichi) second of the Gorgom priests fired electric rays from his hands and light from his eyes.
Bishumu (Mei Hitomi) was Gorgom's priestess. Powerful rays came out of her eyes.
Birugenia (Toru Yoshida) wanted to be Gorgom's chief general. He was armed with a sword and shield. Later he took a second sword, the Satan Sword, which was meant for the next Creation King. He was killed by Shadow Moon who took the sword for his own use.
Shadow Moon does not awaken until episode 35. Shadow Moon's combat techniques were "Shadow Punch" and "Shadow Kick". He also had "Shadow Flash" which allowed him to take control of Battle Hopper. He could fire bolts of energy from his fists and from Satan Sword. The voice actor for Shadow Moon was Jisen Masanori. The in costume actor was Tokio Iwata.
Human scientist Dr. Kuromatsu, Hideomi (Kurobe, Susumu) experimented with turning humans into mutants for Gorgom. He was killed in episode 19.
Gorgom mutants were based on animals, archanids, insects and plants.
