Pokémon Black Version and Pokémon White Version - Evolution

Pokémon Black Version and Pokémon White Version - Evolution

Tags: pokemon-black-and-white, in-depth-guides, evolution

Some Pokémon can evolve:

  1. At the end of any battle (except battles the player lost) in which the Pokémon levels up or after a Rare Candy is used on it and takes effect;
  2. When a certain item is used on it; or
  3. When the Pokémon is traded to another game.

Those are the three basic ways that Pokémon can evolve. Here is a more detailed list.

  • Case 1 (The Pokémon levels up). The evolution can be canceled by pressing B while the Pokémon evolves.
    • The Pokémon is at or above a certain level (most Pokémon)
      • And the Pokémon is male (example: Mothim), or female (example: Wormadam).
      • And Attack is greater than Defense (Hitmonlee), or Attack is less than Defense (Hitmonchan), or Attack is equal to Defense (Hitmontop).
    • The Pokémon’s friendship is 220 or more (example: Chansey)
      • And it’s day (example: Espeon, Roselia), or night (example: Umbreon). Day is from {4:00 a.m. through 7:59 p.m.}, and night is from {8:00 p.m. through 3:59 a.m}.
    • A certain Pokémon is in the player’s party (Mantine). If a Pokémon evolves this way, the Pokémon that must be present is not removed from the party.
    • The Pokémon is at a certain place (example: Nosepass)
    • The Pokémon has a certain move (example: Mr. Mime).
    • The Pokémon is holding a certain item and it’s day (Happiny)
    • The Pokémon is holding a certain item and it’s night (example: Gligar)
    • The Pokémon’s Beauty is at or higher than a certain amount (Feebas)
  • Case 2 (The Pokémon is traded). The evolution can’t be canceled.
    • The Pokémon is traded to another game (example: Machoke).
    • The Pokémon is traded with a specific kind of Pokémon to another game (example: Shelmet and Karrablast will evolve when both are traded together).
    • The Pokémon is traded to another game while holding a certain item (example: Scizor). If the Pokémon evolves this way, that item is removed from it.
  • Case 3 (A certain item is used on the Pokémon). The evolution can’t be canceled.
    • A certain item is used on the Pokémon (example: Pikachu).
    • A certain item is used on the Pokémon and it’s male (Gallade).
    • A certain item is used on the Pokémon and it’s female (Froslass).

Special notes:

  • Shedinja: Shedinja will appear in the player’s party when Nincada evolves into Ninjask, if the player has an item named "Poké Ball" in the Bag and has a free space in the party. The Shedinja will essentially be a clone of the evolved Ninjask, except that it’s a Shedinja named "Shedinja" rather than a Ninjask; has no ribbons, items, or markings; isn’t poisoned, burned, paralyzed, frozen, or asleep; and appears in a Poké Ball. Therefore, among other things, Shedinja has the same Individual Values, base stats (EVs), Exp. Points, personality ID, moves, 32-bit Trainer ID, OT name, and so on of the evolved Ninjask, but its stats are calculated according to Shedinja’s race values. Furthermore, the Poké Ball is used up. (Shedinja is created before Ninjask tries to learn any moves it would have upon evolution.)
  • Silcoon/Cascoon: {For a given Wurmple, if the remainder of the personality ID’s high 16 bits divided by 10 is less than 5, it will evolve into Silcoon; otherwise, it will evolve into Cascoon.}
  • Day-Care: A Pokémon placed in the Day-Care won’t evolve, even if it gains enough Exp. Points for its level to go up.
  • Everstone: In general, a Pokémon holding Everstone won’t evolve. If it evolves using an item, though, it will still evolve even if it holds Everstone.
  • Double Evolution: A Pokémon gets only one opportunity to evolve when it levels up, even if it meets one or more conditions to evolve. For example, if a Sewaddle with a high friendship reaches level 20, it evolves into Swadloon, but not into Leavanny afterward. It must wait until the next time it levels up to evolve into Leavanny.
  • Name Change: If a Pokémon without a nickname evolves, then the Pokémon’s nickname changes to the name of the new species in the language of the game where the Pokémon evolves. No other case can make a Pokémon’s name change upon evolution. A Pokémon’s species name in games before Pokémon Black Version and Pokémon White Version is in all capital letters (for example, PIKACHU, FARFETCH'D, MR. MIME, PORYGON-Z, FEUFOREVE); however, since Pokémon Black Version and Pokémon White Version, its species name has only the first letter of each word capitalized (for example, Pikachu, Farfetch’d, Mr. Mime, Porygon-Z, Feuforêve). A Pokémon that was given a nickname of its species name in a game in a certain language is considered to have no nickname.
