>Unova marks the debut of Mega Evolution in the animeThe anime always introduces new pokemon before the release of their gen
Togepi in the kanto anime followed by marrill and snubble in the pikachu movie short.
Keckleon and Blaziken in the johto anime and latios and latias in the movie.
A bunch of gen 4 pokemon across every piece of media due to the delay and so on and so forth.
That said, despite it being a unova movie advertising the next gen they chose a gen 1 pokemon to advertise a gen 6 mechanic.
>and Mega Evolutions were strictly for older PokemonKind of a moot point to make then they made the older Mon better than the gen 5 and 6 Mon, some of which were in dire need of a buff. Also that's not a hard and fast rule for these generational gimmicks since exclusive z moves and gigantamaxes were given to gen 7 and 8 pokemon.
