Genki Horiguchi
Marvin returned to Japan on several tours even after CMLL Japan folded, often working for Último Dragón's Toryumon Japan promotion. In Toryumon, Marvin defeated Super Nova on July 7, 2002, to win the NWA World Welterweight Championship. Marvin only held the title for 17 days before losing it to Genki Horiguchi, but the title win helped convince Marvin that his future lay in Japan. From 2003 through 2015 Marvin worked primarily in Japan, only making occasional guest appearances in his native Mexico.
