Recurring characters

Kohtaro Minami

Kohtaro Minami (南　光太郎, Minami Kōtarō) is a 19-year-old man who became a mutant cyborg after the Gorgom captured him and his stepbrother Nobuhiko. Both are kidnapped for the sake of having them compete for the right of succeeding the Creation King and command Gorgom to rule the world, but just as his memories were about to be erased, Kohtaro manages to escape. Since then, using the power of the King Stone, he transforms into Kamen Rider Black (仮面ライダーBLACK, Kamen Raidā Burakku) to stop Gorgom and attempt to rescue Nobuhiko from them. He is referred by Gorgom as "Black Sun".

As Kamen Rider Black, Kohtaro fights barehanded using Rider Punches and Kicks to finish his enemies, although he once wields Shadow Moon's weapon, the Satan Sabre, for his final battle against the Creation King. He also uses two motorcycles during the series:

• Battle Hopper (バトルホッパー, Batoru Hoppā): A living motorcycle created by Gorgom, made specifically for the next Creation King. Used by Black during the series, it is temporarily hijacked by Shadow Moon once he is chosen by the Creation King as his true successor, but is destroyed by him once it manages to break free of his control and rejoin Black's side. It is later revived as Acrobatter when Kohtaro evoves into Black RX.
• Road Sector (ロードセクター, Rōdosekutā): Black's secondary motorcycle originally created by Yoichi Daimon for Gorgom before he defects from the organization. Yoichi's son Akira Daimon lends it to Kohtaro until the end of his fight against Gorgom.

During the events of Black RX, Kohtaro lives with the Sahara Family and is captured by the Crisis Empire who ask him to join their side. When Kohtaro refuses, they shatter his King Stone into two pieces, thus rendering him unable to transform into Kamen Rider Black. They throw him into outer space, where the sun's radiation mutated his King Stone, allowing him to evolve into Kamen Rider Black RX (仮面ライダーBLACK RX, Kamen Raidā Burakku Āru Ekkusu) to fight the Crisis Empire and the Strange Demon Soldiers.

As Kamen Rider Black RX, Kohtaro fights armed with the Photon Sword Revolcane (光子剣リボルケイン, Kōshi Ken Riborukien), whose finishing attack is the Revolcrash (リボルクラッシュ, Riboru Kurasshu). During the series, he also gains two additional forms:

• Robo Rider (ロボライダー, Robo Raidā): Also known as the "Prince of Sadness". In this form, Black RX's armor becomes bulky and more robotic-like, with increased strength and resistance at the cost of reduced mobility, armed with the Vortech Shooter (ボルティックシューター, Borutikku Shūtā), a pistol that allows him to perform the Hard Shot (ハードショット, Hādo Shotto) finishing attack.
• Bio Rider (バイオライダー, Baio Raidā): Also known as the "Prince of Rage". In this form, Black RX's armor becomes much sleeker, with enhanced speed at the cost of reduced resistance, armed with the Bio Blade (バイオブレード, Baio Burēdo), which is used to perform the Spark Cutter (スパークカッター, Spāku Kattā) finishing attack.

Like his previous form, Black RX has two different vehicles at his disposal:

• Acrobatter (アクロバッター, Akurobattā): Battle Hopper's upgraded form, created once Kotaro evolves from Black to Black RX which triggers its resurrection. Unlike its previous form, it can speak with its owner. Like Black RX, it also assumes two different forms, which are the Roboizer (ロボイザー, Roboizā), piloted by Robo Rider and the Mach Jabber (マックジャバー, Makku Jabā), piloted by Bio Rider.
• Ridoron (ライドロン, Raidoron): A car created by Kotaro using some blueprints given to him by Prof. Walter, a scientist in one of the colonies the Crisis Empire set up. It's also first car used as a vehicle by a Kamen Rider.

In the series finale, Shadow Moon was weakened by Kamen Rider Black using the Satan Sabre to slash the King Stone and left him inside the Gorgom Headquarters when it explodes. During the events of Black RX, he mysteriously came back to seek revenge against Kohtaro. He now uses the twin Shadow Sabers similar to the Satan Sabre. He was finally defeated by RX when he thrust the Revolcane through his King Stone. He turned good shortly before he died and finally reverted to Nobuhiko.
