Kohei Sato
After the All Japan affair, Yokoi diversified to his singles career aside from Rowdy, and challenged The Predator for the Zero-One United States Heavyweight Championship and Masato Tanaka for the NWA United National Heavyweight Championship. He and Sato also challenged for the NWA tag team titles several times, but they failed. From 2004 to 2006, Yokoi competed sporadically in Hustle as a member of the babyface Hustle Army, teaming up with "Hustle K" Toshiaki Kawada, while trying luck in Zero-One's "Fire Festival" tournaments and keeping his team with Kohei Sato. He was released from Zero-One in February 2007, leaving pro wrestling altogether.
