So if you visit the official website for Sword and Shield, you’ll see a pixelated image of a new Pokémon. If you click on it, this appears: Any thoughts on it? I don’t know what to expect of this new Pokémon, but I do want to point out this this is a clever way to reveal it. Also when you click on the image, Rotom’s cry plays (probably implying that it’s the Pokédex looking up information about it).
The green color scheme makes me think that it might be based on some sort of reptile. It also seems to be holding something. Perhaps a weapon?
A lot of people have thought this could be the Farfetch'd evolution due to the long bit of white with green resembling the leek that Farfetch'd holds.
