Pokémon GO Giovanni has returned with a Shadow Raikou for the month of February. Players must finish the current Team GO Rocket Special Research to gain access to February's Team GO Rocket Special Research.
Players will be tasked with defeating Team GO Rocket, its leaders and Giovanni once more for a chance to rescue the Legendary Shadow Pokémon Raikou. However, many players will be using the encounter to farm Unova stones.
Pokémon GO Giovanni: How to Earn a Unova Stone
The Unova stone remains one of the most sought after items in the whole game since it time-gates many different Pokémon evolutions. It can be frustrating to farm, and sometimes you can only earn one once a week when you finish seven research tasks. But if you beat Giovanni, you're guaranteed one Unova Stone.
Players have all of February to complete the research and a chance to catch the Shadow Raikou. If they fail to finish the research in time, Raikou will escape. Niantic Labs will continue this tradition, so look out for more Team GO Rocket Special Research from Professor Willow every month.
