Ecologically similar Pokémon

The subject of this article has no official name. The name currently in use is a fan designator; see below for more information.

Certain Pokémon are described as ecologically similar^[1] (Japanese: 生態は似ている^[2] ecologically similar) to previously discovered species, but are otherwise completely different Pokémon. This concept was first introduced in Generation IX.

They are often referred to by fans as convergent forms, convergent Pokémon, or convergent species, relating the concept to convergent evolution in biology. They have also been referred to as regional fakes, due to comparisons to the similar concept of regional forms, which are different forms of the same Pokémon. So far, five of these Pokémon have been introduced. Jacq is known for his research on these Pokémon in collaboration with the World Pokémon Ecological Society.^[3]

History

These Pokémon were first identified by the World Pokémon Ecological Society after the discovery of Wiglett during a survey.^[3] Wiglett was initially mistaken as a possible Paldean form of Diglett before it was decided that it was a different species entirely and the similarities were merely coincidental.

In the games

In Pokémon Scarlet and Violet, the player can find Pokémon that are ecologically similar to other species across Paldea, as well as in Kitakami.

Trivia

• These Pokémon are similar to the Paradox Pokémon in that they bear a striking resemblance to certain Pokémon but are nonetheless completely different species.
• Poltchageist and Sinistea are the only ecologically similar Pokémon that share a type.
  • Additionally, they're the only ones where the name of the newer Pokémon is not based on its original counterpart, but rather its evolved form; in this case, Polteageist.
• The concept of ecologically similar Pokémon was first introduced with the reveal of Wiglett before the release of Pokémon Scarlet and Violet.^[3]

Origin

While these Pokémon are officially described as "ecologically similar"^[1], it may be more accurate to describe them as "morphologically similar", as while they have similar physical characteristics, many of them occupy very different ecological niches. The concept has been compared to convergent evolution and parallel evolution in evolutionary biology, both of which can lead to separate organisms independently developing similar or identical characteristics and body plans.
