==Regional condition criteria==
While there are several Pokemon that may have justification in their dex entries or something for being called "regional" evolutions, very few Pokemon ''mechanically'' demonstrate an actual (active) difference in evolution within the same game between a non-regional and regional form. Currently, only USUM's branched Alolan evolutions do ({{p|Pikachu}}, {{p|Exeggcute}}, {{p|Cubone}}). (In fact, it seems in games like SwSh, there's just only a single evolution, like {{p|Koffing}} can only evolve to Galarian Weezing, it has no branch at all for regular Weezing (AFAIK currently).) This makes it hard to say that some of these evolutions ''definitively'' have a regional condition&mdash;another game could show up and have a new way to evolve, say, Galarian Weezing, and it might not be contradictory to SwSh, it could just be (retroactively) attributed to a new kind of condition or...who knows.

So I want to propose some clear criteria for Pokemon that would/could/should be included for this condition.
* '''Clearly regional'''
** Any Pokemon that demonstrably evolves differently in the same game, in areas that can be described as different regions (such as Alola proper vs Ultra Space in USUM)
* '''Presumably regional'''
** Any Pokemon that has a branching Evolution that can arrive at different regional/non-regional forms (example: {{p|Quilava}})
** Any non-regional form that evolves into a new species that was not previously known to exist (example: {{p|Scyther}})
* '''Not regional'''
** Any Pokemon that evolves into the same regional form (e.g., {{p|Meowth}}, in all forms)

I could also see a negative possibility, to the effect of "Any Pokemon that evolve the same in two games set in different regions do not have a regional condition", like if the evolution to {{p|Kleavor}} got an alternate method. But I could also see some extraordinary justification for that (if we can revive fossils, maybe region radiation is possible or something; or maybe two regions are just "so similar!"). So that may not prove out, but at any rate, it's not really an issue at the moment, just something to maybe keep in mind.

There also could be new cases that come up, or edge cases that are fuzzy right now but may come into relief later or something. But I think the points above are a fairly solid starting point, and I'd like to hear what people think. If these are good, if they're confusing or have implications I haven't seen or anything, if you have other ideas, etc.

:I think we can at least keep all cases where a Pokémon can evolve into regional and non-regional forms using the same method for both evolutions, as in the case of Raichu, Weezing, and Mr. Mime.
:Koffing evolves into Weezing or Galarian Weezing by the same method depending on region since this is a regional form.
:In the case of Kleavor and Ursaluna I'm not sure. The Black Augurite is only available in Hisui, but would it presumably work the same way if we used this item in other regions? Maybe we'll find out in future games.
:The Pokémon pages {{p|Scyther}}, {{p|Kleavor}}, {{p|Teddiursa}}, {{p|Ursaring}}, and {{p|Ursaluna}} explicitly mention "in Hisui" as part of their Evolution data. But it seems that the articles {{p|Applin}}, {{p|Dipplin}}, and {{p|Hydrapple}} don't say "in Paldea" like that. Why the difference?
:Arguably pages like Hydrapple, Ursaluna, and Kleavor don't need to mention the region or game as part of their evolution.
:Anyway, I agree with the point that all Alolan Meowth evolve into Alolan Persian, therefore this is not a region-based Evolution. --[[User:Daniel Carrero|Daniel Carrero]] ([[User talk:Daniel Carrero|talk]]) 14:51, 1 March 2025 (UTC)
:I also suggest double-checking those categories:
:* [[:Category:Pokémon with region-exclusive Evolutions|Category:Pokémon that evolve based on region]]
:** [[:Category:Pokémon with Alola-exclusive Evolutions|Category:Pokémon that only evolve in Alola]]
:** [[:Category:Pokémon with Galar-exclusive Evolutions|Category:Pokémon that only evolve in Galar]]
:** [[:Category:Pokémon with Hisui-exclusive Evolutions|Category:Pokémon that only evolve in Hisui]]
:Whatever the criteria, the "region-based Evolution" article and any related categories should probably list the same Pokémon.
:The categories are meant for the pre-evolutions but the category names are misleading. Pikachu is categorized in "Pokémon that only evolve in Alola" but Pikachu is actually perfectly capable of evolving outside of Alola.
:Those categories don't contain cases like Ursaring, Scyther, and Dripplin.  --[[User:Daniel Carrero|Daniel Carrero]] ([[User talk:Daniel Carrero|talk]]) 15:06, 1 March 2025 (UTC)
