J is the human form of the Crocodile Orphnoch, the first of the Lucky Clover sent after Phi having an ability to regenerate from attacks that would kill normal Orphnoch only twice.
A strong, usually silent, black man who's usually seen with his pet chihuahua, Chico. After being killed by Chi's Xeno Clash twice, J was reluctant to continue his pursuit on Phi until Midgley threatened him with being named a traitor & what would come of Chico if he didn't complete his mission. Though J was finally killed by Phi's Grand Impact, Chico ended up in the care of April Kimberly.
