Trainers, A Special Raid Weekend event is on its way! The Legendary Pokémon Latias and Latios will both be available in Raid Battles soon.

Date + Time
Friday, January 24, 2020, at 1:00 p.m. to Monday, January 27, 2020, at 1:00 p.m. PST (GMT −8)

Features

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

These Eon Pokémon 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.

You’ve got this, Trainers—let’s GO!
