    These glitch evolutions function differently to Pokémon Red, Blue, and Yellow, as originally in Generation I it would be possible for two evolutions to take place at once, with a new evolution starting immediately after the old one has finished.

    ????? (FC) must be between Level 18-23 for the evolution into ????? (00) to take place, and if ????? (FC) is raised to Level 24 or higher it appears only the evolution into Ivysaur will occur.

    Methods to obtain

  • Byte shifting via (00) or (FF) (available through stabilizing a bad clone or arbitrary code execution) (e.g. byte shift a total experience of 252 or 64512-64767; unconfirmed).
  • Arbitrary code execution (e.g. through Coin Case arbitrary code execution, wrong pocket TMs, glitch Pokédex categories).


    When the player goes to deposit this Pokémon into a storage box, it may erroneously appear at Level 255 holding an item. Backing out of the menu may cause the game to freeze. This trait is shared with ????? (Gold/Silver FE).

    This behavior does not occur for ????? (Crystal FC) or ????? (Crystal FE).

    Additional sprites

    The front sprites of this glitch Pokémon may be affected based on the location it is encountered, whether an item was used, and the previous enemy battle sprite.
