The MiniDex! is a side-show hosted on TheNationalDex YouTube channel. The show was hosted by Rival Jimmy during Season 1, and by a different host each week during Season 2. The show usually covers Pokémon that are not fully evolved, giving trivia and battle strategy on the Pokémon. These videos are much shorter than the videos of The Dex series. The show took over from The Extra Dex once it concluded. Season 2 was created as part of TheNationalDex's rebranding with the release of Pokémon Sun and Moon in 2016. The format of the episodes changed to covering three Pokémon at a time instead of a single Pokémon per episode.
