Yu-Gi-Oh! Duel Monsters
"Yu-Gi-Oh! GX", known in Japan as "Yu-Gi-Oh! Duel Monsters GX", is the first spin-off anime series produced by NAS which ran for 180 episodes from October 6, 2004 and March 26, 2008. Taking place a few years after the events of "Yu-Gi-Oh! Duel Monsters", the series follows a boy named Jaden Yuki as he attends a Duel Academy, built by Seto Kaiba, in the hopes of becoming the next Duel King. Like the previous seasons, 4Kids Entertainment licensed the series outside Japan and aired it in North America between October 10, 2005 and July 12, 2008, though episodes 157–180 were not dubbed.
