Pokémon x Yu-Gi-Oh

Pokémon x Yu-Gi-Oh! is a crossover fanfiction series by Vengie D. It's a huge series featuring various Yu-Gi-Oh series where the characters use Pokémon instead of Duel Monsters/Magic and Wizards. The series will soon premiere on FanFiction.net.

Despite each series potentially being sequels of the previous entry, they will air together since the major plot of each one does not rely on the reader knowing what happened in previous series and anything related to previous plots are simply explained in great detail by characters regardless of spoilers.

Composition
The universe currently consists of 3 upcoming, named series and 5 other, currently unnamed series.

Argentum
Pokemon x Yu-Gi-Oh!: Argentum is an adaptation of the original Yu-Gi-Oh! manga and anime series. It could be described as a loose adaption mixing manga, anime, and video game plots of Yu-Gi-Oh! with the video game, manga, and anime plots of Pokemon. An example of this includes the Kanto arc replacing Duelist Kingdom, but it uses aspects of both plots (i.e. Mikey needing to go to Kanto to save her father in a similar manner to why Yugi had to go to Duelist Kingdom). The series is also the longest, currently having no written ending due to covering plots encompassing all of the current and future Pokemon video games.

Pokémon Academy
Pokemon x Yu-Gi-Oh!: Pokemon Academy is an adaptation of the Yu-Gi-Oh! GX manga and anime series. It is the closest in adaptations to the source material in terms of plot. The series spans four seasons, one for each year of American high schools.

Twins of Unova
Pokemon x Yu-Gi-Oh!: Twins of Unova is an adaptation of the Yu-Gi-Oh! 5Ds manga and anime series. The series spans three seasons, one for each set of legendary Unova Region Pokemon (Yin-Yang Dragons, Forces of Nature, Swords of Justice). In terms of adaptation, its composition is a mix of AG and PKAC and will continue to be the format for future PKxYGO series moving forward.
