Pokémon Go Legendary Pokémon had been hotly anticipated for some time, and finally arrived one year after the game released.
Fans of the classic games will remember them fondly - from the flying trio Articuno, Zapdos, Moltres to the elusive Mewtwo and Mew in Red, Blue and Yellow to Gen 2's Gold, Silver and Crystal, Legendary beasts Raikou, Entei, Suicune and final Pokédex entries Lugia, Ho-oh and beyond.
These are the game's rarest creatures, and despite many teases and leaks, for a year no one was able to locate them within Pokémon Go (though one did appear unofficially).
However, from summer 2017, things have changed, and following the huge Gym rework and the addition of Raids, have now seemed them appear as part of a release schedule over the summer, which we delve into later in the article along with our advice for how to battle and catch Legendaries, too.
Mewtwo release date, other Legendary Pokémon currently available
Legendaries are primarily caught in Raid battles, and much challenging than standard encounters, so will require as many players as possible to take them down.
Living in major cities with gyms at popular landmarks will naturally attract players without organising before hand - just look out for the blue and white Egg, and get there for the countdown, and provided you are in a popular spot, other players should be there waiting for it to begin.
Otherwise, joining Facebook or Discord groups for your town or area is a popular way to organise groups. In battle, you essentially want to field powerful Pokémon with strong opposing Types.
You can also get Legendaries by completing a week's worth of Research quests. Like Legendaries in Raids, these rotate regularly, and focus on previously released Legendaries for those who missed them.
How to catch Legendaries and how to unlock Legendary Raids in Pokémon Go
Ninatic finally unlocked Legendary Pokémon in Pokémon Go following Pokémon Go Fest. Summer 2017 saw Legendary birds Moltres, Articuno and Moltres come and go, with Legendary beasts Raikou, Entei, Suicune here for Autumn - and the start of a Gen 3 Legendary rollout over the winter, starting with Groudon.
Though they are similar to standard Raid Battles in many ways, there are several differences in both their appearance and capture:
How to capture Legendary Pokémon
Like other Raid encounters, once a Legendary's defeated you have to then catch it. This is difficult seeing as, according to research available from Pokémon Go community The Silph Road, your chances are pretty slim.
