Throughout the franchise, the design 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 consistently left untouched. Pokémon Yellow would later update the front sprites once more, this time explicitly basing them after the Pokémon's appearance in the animated series.

In Pokémon 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, Pokémon Crystal later changed a good handful of sprites, using each Pokémon's respective artwork as a basis. This mostly affected the Johto Pokémon, and this time around the back sprites were also updated here and there.

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 However, many of the Generation I and II Pokémon's sprites were either copied directly from Crystal or based on outdated artwork, as those Pokémon had yet to be redrawn for FireRed and LeafGreen or HeartGold and SoulSilver.

099		Kingler	Generation I core series	Originally had relief on its back, four head spikes instead of six, and the larger pincer was on the opposite side. As a side note, since Pokémon have their front sprites horizontally flipped in the Pokédex or Summary screen in Generation I, Ken Sugimori may have been referencing them when first drawing the artwork for Red and Green. This is supported by Kingler's claw swapping sides permanently from Generation II onward.
