This article is about a/an villain in Kamen Rider 555.

Mr. J (ミスタージェイ Misutā Jei) was the human form of the Crocodile Orphnoch (クロコダイルオルフェノク Kurokodairu Orufenoku), the first of the Lucky Clover members sent after Faiz. He has the ability to regenerate from attacks that would kill normal Orphnoch, the pile of dust he collapses into reforming a minute later, but he can only do this twice before actually dying.


A strong, usually silent black man who spoke perfect Japanese, usually seen with his pet chihuahua, Chaco, whom he cares very much for. After being destroyed by Kaixa's Xeno Clash twice, Mr. J was reluctant to continue his pursuit on Faiz until Murakami threatened him with being named a traitor and what would come of Chaco if he didn't complete his mission. Though Mr. J was finally killed by Faiz's Grand Impact, Chaco ended up in the care of Keiko Kurata.
