Throughout the franchise, the designs of some Pokémon received various amounts of changes. Some were temporary, only lasting for one or two games, while others remained for a fair bit longer, causing a disconnect between the video games and other Pokémon-related media.

Overview

The first few generations are interesting due to the sprites having been made before the artwork, rendering the "errors" and other oddities as nothing more than design revisions.

Generation I, for instance, had the original designs tweaked in some places, with Pokémon Blue giving the original roster new sprites, though the back sprites were left unchanged. Yellow would later update the front sprites once more, this time explicitly basing them after each Pokémon's appearance in the animated series.

In Gold and Silver, the sprites for the Kanto Pokémon are mainly based on the contemporary Red and Blue artwork, with some of the new elements tentatively introduced there (such as Nidoqueen's fangs) making a return. Much like with Yellow, Crystal later updated a good handful of sprites, using each Pokémon's artwork as a basis. This mostly affected the Johto Pokémon, and this time around the back sprites were also updated here and there.

Ruby and Sapphire is likely when the majority of sprites were being made after the artwork, leaving most of the inconsistencies to be minor in comparison to previous generations. However, many of the Kanto and Johto Pokémon's sprites were either copied directly from Crystal or based on outdated artwork, as those Pokémon had yet to be redrawn for FireRed and LeafGreen or HeartGold and SoulSilver.
