I don't know but new generations always mess up the history of the anime.
I mean, anybody remembers the Eevee brothers?
I mean, these liars told his little brother Mikey that he had to choose ONLY between Vaporeon, Jolteon and Flareon to evolve his Eevee, they never told him about Umbreon, Espeon, Leafeon, Glaceon and Sylveon...
I mean, if they were truly so into Eevee then they should know about the other 1000 evolutions Eevee can have.
This means those bastards didn't want his little brother to have a flawless Glaceon or Espeon.
I know we only knew about 3 eeveelutions at the time, but as we know, in the anime when a new generation appears they always knew about them before, like how the hell Brock knew about Cradily, being an extinct pokémon.
And in the Johto Season when they return to Kanto and visit some of their old friends, those old friends have Pokémon from generation 2, even though they always preached that only 150 pokémon existed.
And thinking about that, how the hell could they tell only 150 pokémon existed?
They didn't know about Mewtwo (well, in that case Mew takes the 150th position), but neither did know about the 5 extinct ones, Porygon, and some others, and if we take out Metapod and Kakuna, because like how can some 1 week clothes for Caterpie and Weedle be counted as a pokémon?.
