Latias and Latios zip back for another Special Raid Weekend event!

Trainers, The Legendary Pokémon Latias and Latios are coming back to Raid Battles for a Special Raid Weekend event! These Eon Pokémon haven’t been seen in the skies since January of this year, so be sure to catch them during this weekend before they fly off again!

Date + Time
Friday, June 12, 2020, at 8:00 a.m. to Monday, June 15, 2020, at 10:00 p.m. local time

Features

• The Legendary Pokémon Latias and Latios will be in five-star raids.

Latias and Latios are both Dragon and Psychic type, so it’ll be best to bring along other Dragon-type Pokémon, such as Rayquaza and Dialga. They are also weak to Ice-, Bug-, Ghost-, Dark-, and Fairy-type attacks, so some recommended Pokémon to round out your Raid Battle teams are Tyranitar, Togekiss, and Mamoswine.
