Pokemon Sun and Moon are already out and all Pokemon trainers out there are as busy as ever. Everyone knows that a Pokemon can evolve by increasing their levels through battles, some of them need to meet some special requirements to get the highest form of evolution. Sadly, Pokemon does not tell you how to achieve them and you have to discover mostly by yourself. Why wait when you can have them now? Here's a list of how you can evolve Pikachu, Meowth, and more.

Our beloved Pikachu can evolve into Raichu by using the Thunder Stone to do that. You can buy that on Akala Island. Meowth's evolution is a bit complicated. You can evolve him into a Persian by increasing his level of happiness. Its happiness level can have a little boost when you capture it using a luxury ball. Furthermore, you can increase it when you treat it with a massage in Konikoni City, where you can also check its happiness levels. Other methods of making Meowth happy is by giving it vitamins, winning battles, and giving it a Soothe Bell.

In the same way, you can also evolve Type: Null to Silvally by increasing its happiness levels. Do the same procedure as with Meowth to do this. Ratata and Cubone, on the other hand, will evolve during the night. After evolving, Ratata becomes Level 20 Raticate while Cubone becomes Level 28 Marowak.

The Pokemons which evolve during the day are Yungoos and Fomantis. Yungoos becomes Gumshoos at Level 20 while Fumantis becomes Lurantis at Level 35.

If you have Rockruff, its evolution will always be Lycanroc at Level 25. However, its form might vary depending on where you evolve it. If you evolve it in Sun, you'll get the midday form while the midnight form comes out when you play it in Moon.
