Mewtwo is one of the tougher and rarer Pokémon to encounter in Pokémon Go. You can typically expect to see it appear during special events, and sometimes it’ll be captured by Giovanni, giving players the opportunity to rescue it as a shadow type. What’s even rarer than encountering a Mewtwo, is capturing its shiny version. In its current appearance for five-star raids in the Tour: Kanto event, you have a decent chance to encounter its shiny form.
You can potentially capture a shiny Mewtwo during the Tour: Kanto. Similar to the Special Research task featuring shiny Ditto, it’s hard to come by. The only way you’ll encounter a Mewtwo during the event is to find it in five-star raids. Luckily, these raids will continue for the next week alongside the Kanto Celebration, the upcoming event available for all players in Pokémon Go, not just ones who purchased tickets for Tour: Kanto.
Shiny Mewtwo differs from the original Mewtwo in one noticeable color, and that’s the tail. A shiny Mewtwo will have a green tail, whereas the original has a purple one. It’s not the biggest change, but any eagle-eyed trainer will be able to spot it. If you can couple a shiny Mewtwo with its best moveset, you’ll be able to use Mewtwo in the Master League and take down various trainers.
Your chance to capture a shiny Mewtwo is narrow. You have from February 20 at 9 AM to February 27 at 8 PM in your local time zone.
