Pokemon Yellow: Special Pikachu Edition includes a number of changes from Pokemon Red and Blue. The biggest change any Pokemon collector needs to know is the fact that there are a handful of Pokemon unavailable in Yellow that must be traded from Red and Blue. The following Pokemon cannot be obtained in Pokemon Yellow Version Special Pikachu Edition.
A handful of Pokemon Trainers around Kanto have been given new teams, and almost all in-game trades have been adjusted to contribute to these Pokemon changes.
When it comes to battling, all of the Pokemon’s sprites have been re-drawn, which is simply a visual upgrade to reflect the anime artwork. All of the Gym Leader’s Pokemon have also been updated to mirror the anime. Unfortunately, the anime was not finished when this game released, so not all of the Gym Leader’s Pokemon are the same as the anime.
In addition to the Gym Leaders, Team Rocket has been revised as well. A few Rockets in the game have been replaced with Jesse and James from Team Rocket. They will always have a Meowth, Ekans / Arbok, and Koffing / Weezing. Furthermore, Giovanni will have modified Pokemon teams as well.
Since this is the special Pikachu edition, the only starter Pokemon is Pikachu. See the previous page for more information on Pikachu’s abilities. Your Rival will always have an Eevee, which will evolve into Jolteon, Vaporeon, or Flareon depending on two battles:
If you beat your Rival at Prof. Oak’s Lab and at Route 22, Eevee will evolve into Jolteon.
If you beat your Rival at Prof. Oak’s Lab and lose or pass up the battle at Route 22, Eevee will evolve into Flareon.
If you lose to your Rival at Prof. Oak’s Lab, Eevee will evolve into Vaporeon.
Your Rival’s entire party will be re-balanced throughout the game depending on his starter’s evolution.
Training Pokemon has slightly been altered, too. Almost all Pokemon’s move sets have been changed as they level up, including the new starter Pokemon Pikachu. This will also change some Kanto Trainer’s Pokemon’s move sets.
The only map alterations are the addition of Pikachu’s Beach on Route 19, and all three floors of the Cerulean Cave have been remapped.
Finally, the Mew glitch can be done the same way it is done in Red and Blue, but the original Missingno glitch has been removed.
