I actually rewatched Pokemon Heroes just to get a better understanding of what this ship is (and I like this movie).
"But Slider! You don't take time to research other ships!"
Yeah, I may have some biases. But I own Pokémon Heroes so it's easier for me to access. Anyway, Altoshipping. Latias obviously likes Ash. I honestly think it was Latias that kissed Ash at the end of the movie. Bianca didn't show any interest in Ash at all. Latias on the other hand did.
I feel like a hypocrite. I kind of like this ship but I dislike humans x Pokémon. I'm torn.
