>>58617282Not a single NPC in L:Z-A mentions a trainer's Pokemon experiencing pain under Mega Evolution at any point ever, not even AZ himself who helped kickstart the distribution of Mega Evolution to Kalos. It ONLY gets mentioned with Rogue Mega Evolution, which makes it clear Alolans are a special kind of retarded.
In other words, the stupid bastard scientists of Alola tried conducting research on Mega Evolutions with random mons they hadn't forged a strong bond with, which is why they noted hyper aggression and agony in most cases.
Even LGPE, games in the same gen as the Alola games, immediately course corrected the sheer severity of those dex entries, with Gyarados being one of their first picks to point out "oh yeah, even Mega Gyarados, who goes on a monumental rampage of piss and fury that goes far beyond a normal Gyarados, can actually contain itself thanks to the strong bond it has with its trainer."
