What happened to Mega Evolution?

Rotom made propaganda to make mega evolution look bad. The Kanto Pokédex is perfectly fine when describing the Megas though

I have a theory that the reason the Sun/Moon Mega Dex entries are so dark is because the Alola Region lost a war against Kalos due to Mega Evolution. All the dex entries about the Pokemon being merciless to its opponents could be first-hand accounts of Alolans seeing them in battle. The ones about the mons being in pain, or killing its trainer, could either be myths (hard to tell when you’re busy running for your life), or they may be Alola’s botched attempts to recreate Mega Evolution. This leads to Alola’s defeat, and the demonization of Mega Evolution in the Dex. Or it could just be the Rotom in your dex messing with you. It is part ghost, after all.

Fun fact: Pisncher loves his mega evo because of its sick wings

My head Canon is that the Pokedex entries for mega Pokemon we're written during a series of unethical experiments forcing Pokemon to mega evolve. And that when a trainer with a strong bond with their Pokemon mega evolution Pokemon that Bond allows the Pokemon to withstand the pain. Kind of, that it's willing to sacrifice itself in an act of friendship.

I believe the sun/moon mega dex entries being dark because the Rotom Pokedex itself likes being dark with their entries.

Personally, I think it’s just a Alola propaganda or misunderstanding of mega evolutions, either intentionally or not intentionally trying to make them look bad

10:23 Mega Evolution last appeared in the main series in the Let's Go games, a little after Ultra Sun and Ultra Moon. It was also mentioned in Scarlet and Violet (though not by name).

There's actually evidence to back up the False-True Mega Evolution. In the anime, when Korrina first mega evolves her Lucario, it went rampant. It took a while for them to get used to it. That's where it became a True Mega Evolution.

ngl i feel like the "pushing z crystal" theory is probably the most accurate. if we get more edgy dex entries in legends Z then id be convinced its gamefreak spiting us

1:48~1:55 ORAS is in the same generation that Megas were introduced in.

The edgy writers sure have gone downhill since and after megas were intoduced. Its kinda sad we coulda had cool fun stories but esgy depresso intern thinks hurting your partner would be a good idea for an all in all friendship based game

My personal headcanon is that the Pokemon only feel pain when forced into Mega Evolving. That would explain how you're able to Mega Evolve Pokemon you just got from trading, who you have no bond with. It would also explain why Lysandre is able to Mega Evolve his Gyrados. This is also partially supported by the anime, where Korrina's Lucario goes out of control when it Mega Evolves, because Korrina didn't bond/train with Lucario properly. Another example, in the Volcanion movie the villains use a device to force multiple Pokemon into Mega Evolving, and that also depicts them feeling pain from it. The Mega Stone and Keystone are required to use Mega Evolution, but the bond between trainer and Pokemon is required to master it. EDIT: Okay so yeah, basically EXACTLY the "True Mega Evolution" theory.

Ash-greninja: hah i have your guys strength without the weakness

I saw a theory that megas are very painful and thats why they require a strong bond to be able to endure the pain like how your pokemon just refuses to die because of your friendship even though the move should have caused it to faint

Okay okay... Here me out... What if those "meteorites" that rained down from Hoenn were actually miss-shots from the ultimate weapon? Like excess energy that split off from the main beam and got launched across nearby regions?

I like the theory that the Rotom Dex is letting its ghost-type tendencies creep in for the Pokedex entries... Because Mega forms aren't the only ones with creepy dex entries. The whole regional dex is like that, and all the games following it are significantly less dark. So yeah, I blame the Rotom (as in that specific Rotom... The Rotom Phones are much more chill).

Omega and alpha were still gen 6...

They showed the symbol of mega evolution in the ZA trailer. Its probably gonna become cool again.

Mega was in let’s go

It’s the only gimmick that actually changes how Pokemon look
