Pokémon GO has added Shadow Raikou for the month of February as Team Rocket returns. 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.
Pokémon GO Shadow Raikou: Everything You Need to Know
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.
In the same announcement, Niantic Labs revealed Pokémon GO players can catch Tornadus in raids starting Feb. 4. They can also earn Woobat for the February research breakthrough and participate in a Valentine's Day event.
They'll also have a chance to Pokémon from the Sinnoh Region.
