[b]If you could go back and redo the appearance and type of any old Pokemon, which Pokemon would you redo and how?[/b]
The four Pokemon in the image above [i]([url=http://i.imgur.com/kNFa7Z4.jpg][b][u]link here[/u][/b][/url] for those who can't see it)[/i] are the new unique Alolan forms of the Generation I Pokemon Vulpix, Ninetails, Sandshrew and Sandslash. Vulpix is Ice, Ninetails is Ice/Fairy, and Sandshrew and Sandslash are Ice/Steel.
[spoiler]The reason why these Pokemon have new forms is because of the extreme environments within the Alola region, forcing them to adapt in rather extreme ways.[/spoiler]
