For Pokémon GO's latest update, gamers will have the opportunity to catch some of the rarest and most powerful Pokémon ever. If you and your squad defeat a Legendary Pokémon Raid Boss, you'll then have the chance to land a Legendary Pokémon of your own.
These Legendary Pokémon will in turn lend a hand while taking on the toughest Raid Bosses and Gym Battles, as they ultimately hate to leave their Trainer's side.
If collectively Trainers from all across the globe are able to catch enough Pokémon during the Pokémon GO Fest Challenge Windows, the first Legendary Pokémon will be revealed in Chicago's Grant Park. Following, if participants there then defeat the Legendary Pokémon, that particular Pokémon will begin appearing in Raid Battles around the world beginning July 23.

Earlier this month we saw Pokémon GO allowing you to catch Ash’s Pikachu in a new update.
