Legendary Week

Legendary Week was an event in Pokémon GO.

During the event trainers had opportunity to catch all three Legendary Pokémon of Weather Trio. If Rayquaza was defeated more than Kyogre and Groudon combined, Pokémon that typically prefer windy weather (for example, Bagon) would be more likely to hatch from Eggs from March to March. If not, Pokémon that prefer sunny or rainy weather (like Trapinch or Lotad) would be more likely to hatch. The results given on March, 2018, stated that Rayquaza was defeated more times than Kyogre and Groudon combined.
