Season 0 is the fan name for the first Yu-Gi-Oh anime adaptation, made before the later Duel Monsters series became the version most viewers know. Because it did not receive the same wide international release, many fans outside Japan first discovered it through short clips, reuploads and soundboard pages rather than a full broadcast run. That limited availability helped give it a cult reputation online, and longer clips like this one are still shared by fans who want the earlier, darker tone of the original show.
