The Legendary Heroes Pokémon Go event is live and available to all mobile game players for a limited time. For those who participate, there’s a free Timed Research you can work on, and you can choose to go down the Sword and Shield path, each with a distinct Collection Challenge.

For those who choose the Sword Path, there’s a special Catch Collection Challenge you must work through during the Legendary Heroes event. This will happen from Sept. 26 to Oct. 1, giving you a few days to catch them all. They all won’t appear the same way. Some are easier to catch than others, and you might need to seek them out using specific items to encourage them to appear. Here’s what you need to know about how to catch all Sword Path Catch Collection Challenge Pokémon in Pokémon Go.
