When you fought against these two Pokémon you could think "hey, I know you!", while most of the Pokémon you fight against during the whole franchise are just used as weapons (you only know them in battle, after that you forget they existed).
Damn, these two are even in your 1st Alola champion feast and they congratulate you as another important character. They showed that the Ponémon are also sentient species
