5. Alola Forms
Helping to tie Sun and Moon’s tropical theme into the Pokémon themselves is the introduction of Alola forms, which transform various first-generation Pokémon into bigger, stronger versions. For instance, there’s a super tall Exeggutor that has Dragon abilities and ice versions of Nintales and Sandslash. Unlike the Mega Evolutions introduced in Pokemon X and Y, which were temporary transformations, the Alola forms are effectively all new Pokémon and are a creative way to change up the designs and abilities of some of the most popular and beloved Pokémon. One important thing to note is that Sun and Moon have different Alola forms available, so you may want to research which ones you can obtain in-game before deciding on which version to get.
