I doubt. That would make it debut before even the middle stages of the SV starters have been officially revealed and it would most likely go down to let Eternatus & Charizard shine which wouldn't be a good first impression unless it pulls a Drapion/Spiritomb.

So what if this mystery Pokémon is the final evolution of the duck?
