- Strongest Monster Gran Zairus (44 & 45): A bird-like monster who was Emperor Crisis' best soldier and worked with Bosgan when summoned by Lord Crisis. While the 10 veteran Kamen Rider team fought the Chaps, Black RX went one-on-one with Bosgan and killed him. Turning his attention to Gran Zairus, Black RX became Bio Rider and destroyed the monster from the inside out. For a time, the 10 veteran Kamen Riders thought that Black RX had been killed, but Bio Rider resurfaced and explained that he bailed out in time before destroying the Spirit World demons. Was used for "Bruticon" in Saban's Masked Rider.
- Spirit World Inhumanoid Army (45): When Kamen Rider Black RX was believed to be dead after the battle against Gran Zairus, Maribaron revived the spirits of Skullma, Metaheavy, Zunojin, Gynaninpo, Gynakamakil, The Lead Culculten, Elgitron and Antront to kill the other 10 Kamen Riders. Because they are dead spirits, they are all a grayish-white in color. Gynaninpo's spirit impersonated Kamen Rider 1. All of them were destroyed by Bio Rider.
