Kamen Rider BLACK RX is a playable character, debuted in Kamen Rider: Battride War Genesis.


After defeating Gorgom, but cost amount of his Kamen Rider BLACK's Kingstone of powers, leaving it becomes just a memento, 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 half a year later, Kotaro was abducted into the interstellar mother-ship 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 King Stone damaged, floating aimlessly through space. However, the sun's radiation altered his King Stone 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, Black RX was in a state of sorrow and sadness over the death of Hitomi that he invokes a new power, Robo Rider. Using his power, Robo Rider 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 Hitomi's memory, Khtaro 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 Robo Rider 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, Shadow Moon was finally defeated when RX thrust the Revolcane through Shadow Moon's King Stone, 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. After destroying the Crisis Empire for good, Kotaro bids farewell to the remaining Sahara siblings and his allies to pursue the remnants of the Crisis Empire.

In Super Hero Taisen GP after Shocker alters the timeline by sending Kamen Rider 3 into 1973, Kotaro's timeline changed where as he didn't received RX powers in the present, yet regained his original memories on what happen in the timeline he is in now, and later after sacrificing his life saving a recovered Shinnosuke and Kiriko from Shocker's raid on Special Investigation Office and Drive, Kotaro is revived and regain his BLACK RX power, thanks to Shinnosuke's light, and receive RX powers back once more. Learning that Drive challenge Shocker for a race and Shocker themselves secretly plotting a dirty tricks, he is joined by Faiz and Mach to counter Shockers' cheats, and to save Kiriko and Yuto Sakurai/Kamen Rider Zeronos. After Drive won, in a same time Rider 3 redeeming himself and Shocker doesn't know how to accept their lost, using Rider 3 as a vessel for Rider Robo's power to destroy the Riders and their civilian resistance, BLACK RX and his Rider resistance allies are joined a fully recovered Royal Ace Kamen Riders from Kamen Rider Blade, until by the luck, Rider 3's will of redemtion, thanks to Shinnosuke's emphaty revives original Double Riders and restores Shocker Riders' memories back to Kamen Riders, then Rider 3 manage to escape from the Great Leader's control of the Rider Robo, rendering the leader powerless to use a timeline modifier, when he is gone too far erasing most of the Riders from the existence.
