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.

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.
The first few generations are interesting due to the sprites having been made ''before'' the artwork<ref>[https://youtu.be/9l8V_eQ6wGQ?t=273 Game Informer interview]</ref>, 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 [[Pokémon_anime|animated series]]. In this game, the bulk of the issues stems from the updated palettes, which namely caused {{p|Rattata}}, {{p|Shellder}}, {{p|Cloyster}}, {{p|Starmie}}, {{p|Ditto}}, {{p|Porygon}}, {{p|Dratini}}, {{p|Mewtwo}}, and {{p|Mew}} to be visibly miscolored.
[[Generation I]], for instance, had the original designs tweaked in some places, with {{OBP|Pokémon Blue Version|Japanese|Pokémon Blue}} giving the original roster new sprites, though the back sprites were left unchanged. {{v2|Yellow}} would later update the front sprites once more, this time explicitly basing them after each Pokémon's appearance in the [[Pokémon anime|animated series]].


In [[Pokémon Gold and Silver]], the sprites for the [[Kanto]] Pokémon are mainly based on contemporary ''Red and Blue'' artwork, with some of the new elements tentatively introduced there (like Nidoqueen's fangs) making a return. Much like with ''Yellow'', [[Pokémon Crystal]] later changed a good handful of sprites, taking a Pokémon's respective artwork as a basis. This namely affected the [[Johto]] Pokémon, and this time around the back sprites were also updated here and there.
In {{2v2|Gold|Silver}}, the sprites for the [[Kanto]] Pokémon are mainly based on the contemporary {{2v2|Red|Blue}} artwork, with some of the new elements tentatively introduced there (such as Nidoqueen's fangs) making a return. Much like with Yellow, {{v2|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.


[[Generation III]] is very likely when artwork was starting to be made before the sprites, leaving most of the inconsistencies to changed colors or slightly off-model sprites.
{{2v2|Ruby|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 {{2v2|FireRed|LeafGreen}} or {{2v2|HeartGold|SoulSilver}}.

| style="text-align:left" | Originally had round ears instead of triangular ones, as well as two leaves instead of four. Red and Blue changed the ears, while Yellow changed the leaf count. The two-leaf design returned in Generation II, though only on the front sprites. The Generation I back sprite features a tail. The two-leaf design was reflected in its Red and Blue artwork. Interestingly, The Red and Blue front sprite depicts it as bipedal, despite these games' Pokédex stating that Ivysaur cannot stand on its hind legs.

| style="text-align:left" | Originally had spots, round ears instead of triangular ones, two leaves instead of four, and five petals instead of six. Red and Blue changed the ears and leaf count, while Yellow removed the spots and changed the petal count. The petal count was not carried forward after this, however, as it only appeared on the Silver front sprite before Diamond and Pearl. The Generation I back sprite features a tail. The five-petal design was reflected in its Red and Blue artwork.

| style="text-align:left" | Back sprite has relief, and the larger pincer is on the wrong side. The ''Red and Blue'' sprite has symmetrical pincers, instead of only having a single large one. As a side note, while the ''Red and Green'' and ''Yellow'' sprites are on-model, the larger pincer appears on the wrong side in battle. This is because in Generation I, a Pokémon's sprite gets horizontally flipped in its Pokédex entry. This suggests that this sprite was made with the Pokédex in mind.
| style="text-align:left" | 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.
