|This article is about a/an villain in Kamen Rider SD.|
- This article refers to Shadow Moon from Kamen Rider SD. For the original from Kamen Rider Black and Kamen Rider Black RX, see Nobuhiko Akizuki.
Shadow Moon: A member of GranShocker. The brother of Black RX and apparently a Kamen Rider himself. This version of Shadow Moon tries his best to be evil, but falls short of his own expectations. He is armed with the Satan Saber and an unknown motorcycle (possibly a Road Sector modification). He is constantly teased by Black RX, whom refers to him as "Sunshine Moon."
