The Legendary Pokémon Rayquaza is still appearing at Pokémon GO Gyms, and for a limited time, it is being joined by two other Legendary Pokémon originally discovered in the Hoenn region. Kyogre and Groudon are briefly returning to Gyms from now until March 5, 2018, so you have only a few more days to find and catch them. If you need help taking down these powerful foes, be sure to check out the official tips for Kyogre, Groudon and Rayquaza.

If Rayquaza is defeated more than Kyogre and Groudon combined, Pokémon that typically prefer windy weather (for example, Bagon) are more likely to hatch from Eggs from March 5 to March 16. If not, Pokémon that prefer sunny or rainy weather (like Trapinch or Lotad) are more likely to hatch. According to developer Niantic, Rayquaza is currently being defeated more than Kyogre and Groudon combined by a margin of 52 percent vs. 48 percent.
