Reshiram is a legendary Pokémon, which means in Pokémon Go, you will only be able to capture it during five-star raids. You can engage in these five-star raids during limited times. When they do become available, they are the toughest encounters available in the game. Not only do you require a raid pass to access it, but you will probably need at least four or five friends to help you defeat it.
Reshiram is a Dragon and Fire-type Pokémon. It will be weak to other Dragon-types, along with Ground and Rock-types. It’s strong against Grass, Ice, Bug, Steel, and other Dragon-types, so of your available options, you may want to avoid taking other Dragon-types into the encounter. You have better Ground and Rock-type options, and there are several choices available to you.
Pokémon counters to Reshiram
For those looking to optimize on Reshiram’s Ground and Rock-type weaknesses, there are plenty of options that fit the bill. The best include Rhyperior, Tyranitar, and Garchomp.
Rhyperior is a Ground and Rock-type Pokémon, meaning it likely won’t take too much damage against most of Reshiram’s attacks. Of the available attacks a Rhyperior can know, the top choices include mud slap and earthquake, smack down and stone edge, or smack down and rock wrecker, the latter of which is a Community Day-exclusive move. While rock wrecker is the best option, not everyone will have access to it. Earthquake and stone edge are still excellent attack options.
Tyranitar is a Rock and Dark-type Pokémon. While it does not have as many Rock-type moves to use against Reshiram potentially, it is still a superior choice. You can use one that knows smack down and stone edge, bite and stone edge, or smack down and crunch. Bite and crunch will not be as effective as Reshiram because they are Dark-type moves, but if you have a powerful Tyranitar, they’re a good choice to have in your line-up.
The excellent final choice is Garchomp, which is a Ground and Dragon-type Pokémon. Of the options, it’s a double-edged sword because it is weak to any of Reshiram’s Dragon-type attacks, but Reshiram is also vulnerable to them. It’s a good option for those who want to take a risk, especially against a Reshiram consistently using non-Dragon-type attacks. The best moves for a Garchomp to know include dragon tail and earthquake, mud shot and outrage, or dragon tail and outrage. All of them are excellent choices because they status-type-attack-boosts (STAB) moves.
If you do not have any of these options, you can always choose one these: Groudon, Rayquaza, Hazorus, Rampardos, Salamence, Paiki, Terrakion, Dialga, Excadrill, Dragonite, or Golem. Any of them are solid options for you to go with when engaging in this raid.
After you complete the five-star raid, you will receive a series of premier balls based on how much you contributed to the raid, if you did it with trainers who are your friends, or if the raid started at a Gym owned by your team. Any five-star raid is available to all players with a raid pass, but they only spawn for a limited time and rotate our what legendary Pokémon is residing there.
