Evolution (Japanese: 進化 Evolution) in the Pokémon franchise, is the first evolution method when one Pokémon, upon reaching a certain level, using a certain stone, learning a certain move, or is traded, evolves into a different Pokémon. In Pokémon Gold, Silver, Crystal, HeartGold and SoulSilver games, it says that Professor Elm is an expert on evolution and discovered that Pikachu evolves from Pichu.
Normal Evolution Tricks
First Evolution Method
Pokémon gain experience after battling wild Pokémon and Pokémon Trainers. The more experience a Pokémon gains, the more it levels up. When a Pokémon reaches a particular level, it will evolve into its next form, if it has one. This is very helpful to most Trainers who want their Pokémon to become stronger.
There are ways to share experience, such as allow a Pokémon you wish it to evolve to hold Exp. Share. It is a hold item that allows the user to earn experience even if it did not participate in the battle. This is a convenient tool if you want to level up a new or low-level Pokémon.
You can prevent evolution by simply press the 'B' button on the Game when the Pokémon is attempting to evolve. This is useful as some Pokémon will learn moves that cannot be learned in a later form or if you want a Pokémon to learn a move earlier than usual. For example, Gabite. If you let Gible evolve into Gabite at level 24 it will learn Dragon Rush at level 49, but if you keep Gible it will learn Dragon Rush at level 37. Sometimes it doesn't matter if you let it evolve or not. The Pokémon can hold an Everstone, which keeps them from evolving, so that you don't have to keep cancelling the evolution every time the Pokémon levels up. However, if your Pokémon has evolved, it might not evolve again (Raticate, Linoone, etc.) Although some Pokémon can evolve more than once (Poliwhirl, Cascoon, etc.), some basic Pokémon just can't evolve, due to undiscovered forms, or if they are really rare (Chatot, Groudon, etc.) There are also Pokémon that can evolve into different things like love, choice, etc. For example, Eevee, Poliwhirl, Wurmple, or Kirlia.
Second Evolution Method: Mega Evolution
- Main article: Mega Evolution
Select Pokémon are able to obtain a second form of evolution called Mega Evolution, where the Pokémon gains a boost in strength and/or change in abilities. Only fully evolved Pokémon are capable of Mega Evolving with the use of a Mega Stone, a held object. However, this second evolution method lasts only for one battle, the Pokémon devolves into their pre-evolved form at the conclusion of the battle.
Special Condition Evolutions
Some Pokémon will not evolve unless you use a special stone called an Evolution Stone. These special Items are linked to the Pokémon's type. Here are a list of Pokémon that can evolve by giving them the stones.
Some items are needed for a Pokémon to evolve. If a Pokémon hold the item allowing it to evolve, let it level up once and it will then evolve into the second form.
