Which Of These Supposedly Leaked Mega Evolutions In Legends Z-A Just Have To Be True?

When it comes to counterparts, both are expected to mega evolve, so those are leaks one can believe, as can leaks that give mega evolutions to those part of branched evolutions where the other already has one such as Slowking and the Pokémon oddly enough missing one in Gen VI. It’s good that we’re finally seeing mega evolutions again in Legends Z-A, shame however that they might be put back to rest afterwards.
