Pokemon Multiverse: How many worlds

So I'll acknowledge that it looks like Gengar's Grin did a theory on this about 4 years ago, but I thought mine was different enough and required enough explanation to warrant its own thread. Not to mention, I don't thin gen 7 had been released at that point in time, and oh boy did that add a bunch.

So to start off, I believe that there are, at minimum, between 65-68 different universes in the Pokémon multiverse. One of those 68 is debatable, and it would be understandable if you would decide not to count it. Two more of them are more theoretical, though I think makes sense for them to exist. So that's why I say between 65-68. Keep in mind, this is across the Pokémon franchise as a whole, not just the main series games. I also want to say that there might be some spoilers here, especially for the Mystery Dungeon games, which are the sources of several of these worlds.

Alright, so this is going to be a long explanation, so to make it not so bad, I made a chart that I probably spent way too much time on. Explanations provided below the chart:

Spoiler: Pokémon Multiverse

• Yes, I included our world in this chart. Reason being, in Red/Blue Rescue Team and Gates to Infinity, you, the player, are the main character, transported from this world to the Pokémon world. Also, the original four games included names for real world locations, meaning that the original gen 1 games aren't too far removed from our own world. This is the world I was referring to when I said you could reasonably not count on the list.
• Each version of the game is implied to be its own world based on the Pokémon available there. There were also substantial changes after green and in yellow, so all four of the original games would count as their own universes
• In U2 through U7, all games based in regions originally released in gen 1-5 are interchangeable with other games taking place in in the same region, so long as the Mega Evolution mechanic doesn't exist.
• In U8 through U13, all games containing mega evolution could theoretically be interchanged with other games taking place in the same region, so long as they also contain Mega Evolution.
• ORAS is where it gets complicated. Especially concerning the Delta episode, but in order to get into that, I need to explain the main conflict of the first Mystery Dungeon games. The Rescue Team games came out during gen 3, meaning that all Pokémon, and only Pokémon, up to gen 3 were available. To beat the game, you need to save the world from a falling meteor by getting help from Rayquaza to destroy it. Later, you can access a dungeon that had been formed by falling fragments of the meteor, where you can encounter Deoxys, which had been inside the meteor. This is the same meteor that you destroy with Rayquaza in the Delta episode, meaning that in some version of of the Delta episode's events, the meteor was sent to another world and, as Zinnea warned, nearly destroyed another world similar to Hoenn. Multiverse theory would confirm that a version of the world where you don't destroy the meteor in the Delta episode probably does exist, but I guess these two "meteor warp" worlds could be considered more theoretical than confirmed.
• I did include the manga, Origins, and the main series Pokémon anime because none of those really share a canon perfectly with any of the games. Snap is pretty much confirmed to take place in the anime world. A cameo from Ash's Pikachu in Detective Pikachu also confirms that it takes place in the anime world.
• I think the "Other Universes" are explained well enough in the chart. Those distortion worlds really add to the count though, geez.
• Super Mystery Dungeon has to exist in a separate universe from the other mystery dungeon games, since mega evolution exists.
• A split timeline created in each of the Explorers game would have created an alternate universe for each of the Explorers games.
• The "This complicates things" notes under Conquest is there because Conquest is a crossover game between Pokémon and Nobunaga's Ambition, which is a series created by Koei. Yep, a crossover with a game that's not even owned by Nintendo, which means the Pokémon universe theoretically extends into whatever kind of universe Nobunaga's Ambition takes place in, further giving credibility to the theory that all fictional universes are connected in some way.
• Let's go Pikachu and Eevee were kind of hard to place. There's Mega Evolution in them, so they could probably take place somewhere in U8 through U13. Since this is just the minimum count of alternate universes, I decided not to count them.

Well, I think that about covers it. Remember, this is the minimum number of worlds in the Pokémon Multiverse. There could even be more involving other spinoff games I'm not familiar with. Theoretically though, there's an infinite number. Every individual cartridge that will ever be owned, and every save file played throughout the existence of Pokémon could technically be considered its own universe and many others probably exist that will either be revealed later or that we might only ever speculate about.

 

Those are listed on there, but if there are any other worlds in the anime/manga, I might not know about them since I'm not fully up to date.
