Invasion of Team Rocket!

Team Rocket has invaded the Pokémon Go world! There are some pokestops whose Team Rocket has power! They are ashes, and as you pass them, a team rocket grunt wants to battle you! They use shadowy Pokémon, meaning they turn ordinary Pokemon into another type of Pokemon. At the end of the battle, you can capture a Team Rocket Grunt Pokémon! You can purify it, or get it back to normal. With this, this Pokémon gets stronger and with higher CP.
