Masuda on Meltan

Please tell us more about the new Pokémon, Meltan. Was it always planned to debut first in Pokémon Go? And was it designed in collaboration with Niantic, or internally at Game Freak?

It All Comes Together.

> Niantic will never be given special treatment again. This special gift Pokemon (Meltan) will be the final time Game Freak works hand in hand with them.

> He definitely had the original Kanto Pokemon designs in his mind ...
