Kamen Rider Black RX (character) - Kotaro Minami

Kotaro Minami

After defeating Gorgom, Kotaro Minami found himself homeless until the Sahara family embraced him into their family. With their connections, he found employment as a helicopter pilot for their family business, and began to build a new life for himself. But five years later, Kotaro was abducted into the interstellar mothership of the Crisis Empire. Knowledgeable of his identity as Kamen Rider Black, the organization attempted to offer him to join them. Kotaro refused so they had him jettisoned into space after leaving him incapacitated and his Kingstone damaged, floating aimlessly through space. However, the sun's radiation altered his Kingstone as he miraculously survived entry into Earth's atmosphere. Upon his rebirth, Kotaro learned he had evolved into Kamen Rider Black RX. With his new powers and vehicles, he battled the Crisis Empire and thwarted their plans to take over Earth.

When Hitomi Sahara was kidnapped by Maribaron to assume the identity of the Crisis Empire's only living heir, Kotaro uses Deathgaron to enter the Desert of Death after them. By the time he finds Hitomi, Kotaro falls into a trap set up by Maribaron to do away with him and Deathgaron. When it looked as if Deathgaron had actually killed Hitomi, RX was in a state of sorrow and sadness over the death of Hitomi that he invokes a new power, RoboRider. Using his power, RoboRider fatally wounds Deathgaron before learning that the Hitomi killed was a fake and the real one is being taken to the Valley of miracles. On his way, he meets Joe the Haze who is under the control of Necksticker, freeing him before they and Shigeru are captured by Maribaron and the Princess Karuoriya. It was after they break free that Kotaro realizes the princess is Hitomi, who was abducted and was force grown by the nearby waterfall to replace the real princess who died. When he attempts to restore Hitomis memory, Kotaro is forced to surrender when the Triplon captured Shigeru and Joe. Kotaro was then placed into a room for a hole designed to counter his abilities as both RX and RoboRider for a slow painful death. His rage to save those he loves invokes another new form, Bio Rider. After killing Triplon, with Shigeru's help, Kotaro succeeds in having Hitomi regain her memory as she and the other kidnapped girls are returned to their original ages by the people who originally resided in the valley. With only Joe, Shigeru and Hitomi knowing his identity, Kotaro returns to Earth.

During the middle of the series, Shadow Moon mysteriously returns to seek revenge against him, shortly after, Shadowmoon was finally defeated when RX thrusted the Revolcane through Shadow Moon's Kingstone, effectively turning him good shortly before he died and finally reverting to Nobuhiko. In the finale, he was helped by the 10 veteran Kamen Riders to destroy the Crisis Empire.
