Pokémon with Blaze
As a natural ability
|If any of the Pokémon were introduced before the generation that Blaze was introduced in, then they will not have it as a natural ability until then.|
|Hidden abilities were not introduced until Generation V, so if any of the Pokémon were introduced before that, then they will not have Blaze as a hidden ability until then.|
