Reshiram Pokémon GO will be soon available to encounter in Pokémon GO. It will be the first of the three available to battle, with the others coming soon after. Here's how to catch the Legendary Vast White Pokémon.
Reshiram Pokémon GO: How to Catch
Reshiram, along with Zekrom and Kyurem, will be making their way to legendary raids in Pokémon GO. From 1 p.m. May 26 to 1 p.m. June 16 in your local time, you can encounter Reshiram in five-star raids.
On Wednesdays during the event period, there will also be a special Raid Hour at 6 p.m. in your local time. Reshiram will appear in raids more frequently during these times.
To catch Reshiram, you'll have to beat it in battle. It's a dual Fire and Dragon type, and it's only weak to Ground, Rock and other Dragon moves. It will use Dragon or Fire moves against you, so bring a tough Rock like Terrakion and a strong Dragon like Dialga or Palkia to cover both of those move combinations.
Once you've defeated it in battle, you'll get to catch Reshiram. Catch one now, and it'll prove to be a silver bullet when you have to fight Kyurem in the coming weeks.
