|This article is about a/an ally in Kamen Rider Black RX.|
Joe the Haze (霞のジョー Kasumi no Jō) is a master of the fighting style Kasumi Kenpo. He is one of Kotaro's closest friends and considered just as close as he was to Nobuhiko. Joe was originally a human from Earth who willingly allowed the Crisis Empire to convert him into a cyborg, losing all memory of his past and actual name. Under the control of Nexticker, Joe attacked Kotaro during his attempt to save Hitomi, becoming his ally once he regained his mind. He ended up getting injured by Bosgan during RX's fight with Gynagingam. He soon recovered and came back to help Kotaro.
