Yu-Gi-Oh!

The Yu-Gi-Oh! watch order threads together every anime series, four movies, and an OVA into one chronological path across the whole franchise. Start with Episodes 1-27, the original Studio Gallop run, then the first Yu-Gi-Oh! Movie before the flagship 224-episode Duel Monsters series. Slot Pyramid of Light and later The Dark Side of Dimensions around that era, then continue through GX (Episodes 1-180), 5D's (Episodes 1-154), and the Bonds Beyond Time movie plus the Stardust vs. Red Demons OVA. From there watch Zexal and its second half (two 73-episode blocks) with the Aim for Number 1 in the World special between them, followed by Arc-V (Episodes 1-148) and finally Vrains (Episodes 1-120). This is the correct order for tackling the full Yu-Gi-Oh! chronology, including all movies and OVAs, so you can move series to series without missing the connective duels.
