This is a character list for the eighth and ninth Kamen Rider series Kamen Rider Black (仮面ライダーBLACK, Kamen Raidā Burakku) and Kamen Rider Black RX (仮面ライダーBLACK RX, Kamen Raidā Burakku Āru Ekkusu), respectively.
Kotaro Minami (南 光太郎, Minami Kōtarō) is a 19-year-old man who became a mutant cyborg called the Batta Mutant (バッタ怪人, Batta Kaijin) after the Gorgom captured him and his stepbrother Nobuhiko. Both are kidnapped for the sake of turning them into the Century Kings by 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, Kotaro manages to escape. Since then, using the power of the Vital Charger belt and the King Stone of the Sun, he transforms into the Century King Black Sun (ブラックサン, Burakku San), who re-dubbed himself as Kamen Rider Black, to stop Gorgom and attempt to rescue Nobuhiko from them.
As Kamen Rider Black, Kotaro fights barehanded using Rider Punches and Kicks to finish his enemies, although he once wields Shadow Moon's weapon, the Satan Saber, for his final battle against the Creation King. He also uses two motorcycles during the series, which are as follows:
During the events of Black RX, Kotaro lives with the Sahara Family and is captured by the Crisis Empire who ask him to join their side. When Kotaro 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 the "Child of the Sun" (太陽の子, Taiyō no Ko), Kamen Rider Black RX, to fight the Crisis Empire and the Kaima Soldiers.
As Kamen Rider Black RX, Kotaro wields the Revolcane (リボルケイン, Riborukein) rapier, which allows him to perform the Revol Crash (リボルクラッシュ, Riboru Kurasshu) finisher. During the series, he gains access to two additional forms, which are as follows:

Nobuhiko Akizuki (秋月 信彦, Akizuki Nobuhiko) was born on the day of a solar eclipse alongside his stepbrother Kotaro Minami, revered by the Gorgom as the heirs to their leader's throne: the Century Kings "Shadow Moon" and "Black Sun". Raised together, the two were like brothers. Once the two were of the ideal age, Gorgom captured them and infused them each with a King Stone. While Kotaro manages to escape with his memory intact, Nobuhiko was turned completely into a Batta Mutant with his mind wiped clean while left in a comatose state on life support due to the injuries he sustained during Kotaro's escape before being finally reborn as Shadow Moon (シャドームーン, Shadō Mūn) through the Stones of Earth, Heaven, and Sea. Shadow Moon sets up his regime as a general of Gorgom, serving as Black's nemesis and forcing him to fight him so he can become the new Creation King. In their final battle, Shadow Moon is weakened by Kamen Rider Black after the Satan Saber is used to slash his King Stone. Though he appears to die after being left inside the Gorgom headquarters when it explodes, Shadow Moon returns years later to seek revenge against Kotaro, who is now Black RX. However, he lost all of his memories related to Gorgom after its destruction. He is finally defeated by Black RX when he thrust the Revolcane through Shadow Moon's King Stone, destroying it once more. He turns back into Nobuhiko, renouncing his evil ways as he saved two children trapped in the explosive lava, shortly before he dies.
Due to the critical injuries he sustained during Kotaro's escape, Nobuhiko was further upgraded with cybernetics during his hibernation period under Gorgom's clutches before he fully awakens as Shadow Moon. As such, his overall strength increases compared to his counterpart:
