Rowlet, Litten and Popplio are going to evolve into an Archer, a Wrestel and a Siren respectively and they're going to be Grass/Flying, Fire/Fighting, Water/Fairy but if you do some things with happines and z-stones they will evolve into a gigant gentleman owl (still Grass/Flying), a panther with red streaks (Fire/Dark) and a narwhal (Water/Ice). Pokémon with Alolan Forms (Raichu, Marowak) will have regional forms for pre-evolutions too (Pikachu, Pichu, etc). Some Pokémons like Parasect, Galvantula, Ariados will receive some special love, do you believe in the hearts of the cards?. Alolan Solrock and Alonan Lunatone are real but there are two versions of them: you will find "Rocked Lunatone" and "Alive Solrock" in Pokémon Sun and vice versa on Pokémon Moon. Rotomdex will recieve some special upgrades as soon as you do some things with Kakui and Rockruff. Another special Pokémon will be early revealed with an official trailer.
