Kohtaro Minami, alternatively spelt Kotaro Minami, is the main protagonist of both Kamen Rider Black and Kamen Rider Black RX. Initially chosen by Gorgom to become Century King Black Sun, Kohtaro later escapes and fights against them as Kamen Rider Black. After the defeat of Gorgom, Kohtaro later faces the Crisis Empire and is eventually reborn as the evolved Kamen Rider Black RX.

Starting with Kamen Rider Decade and continuing onto most of the later crossover movies, there are two incarnations of Kohtaro Minami who are independently Black and Black RX.

Kohtaro was born on the day of a solar eclipse, along with his stepbrother Nobuhiko Akizuki, within the same hospital. Gorgom noticed this, and both brothers were entitled heirs to their leader, the Creation King's throne. After Kohtaro's parents deaths from an apparent accident, Prof. Akizuki adopted Kohtaro alongside Nobuhiko and Kyoko. On the night of Kohtaro and Nobuhiko's 19th birthday, they were captured by Gorgom and were remade into cyborgs and infused with Kingstones. Kohtaro received the "Stone of the Sun" to become Century King Black Sun.
