Fnog

Master Fnog was a martial arts teacher at the Cookieville Minimum Security Orphanarium. Among his students was the then teenaged Leela, one of his best students. However, Fnog believes that the very best fighters must possess the Will of the Warrior, which no female being can have, thus he didn't let Leela attend to the Junior Championships and continuously teased her. In 3000, he was trainer for the new Ultimate Robot Fighting League star Destructor who he did not so much train but remote control in the title bout against Bender. Leela got to beat him up during the events of Raging Bender, since then he has made no further appearance.
