More information

Pokémon
We will have pokémon up to the fourth generation, as well as new battle backgrounds and rivals that await our adventure. In addition, an increase in difficulty has been included, perfect to test our pokémon, so Ash and Pikachu will not have it easy.
Features and functions
We will have a redesigned Kanto to find new routes and rivals, all reminiscent of Sinnoh. The best thing is the day and night cycle activated, which will offer a lot of diversity to the game, in addition to characters from the anime and other pokémon games in the adventure.
History
After defeating the Elite Four, you discover that Pokémon from the Sinnoh region have appeared, and the Fire, Aura and Thunder emblems have been activated, awakening the legendary Entei, Suicune and Raikou. Team Rocket tries to capture them, and Professor Oak asks you to stop them. With the help of Pikachu, you start a new adventure in this new region.
