Ho-oh is a difficult five-star raid encounter in Pokémon Go. You will want to bring various trainers with you when you attempt to fight it, and even then, it won’t be an easy process. Ho-oh made its first appearance in video games on the cover of Pokémon Gold Version and was on the cover of the game’s remake Pokémon HeartGold. In Pokémon Go, you can only encounter this legendary bird at specific times through five-star raids.
Ho-oh is a Fire and Flying-type Pokémon, making it a fearsome opponent to any Grass, Bug, and Steel-types. You want to focus on using Electric, Water, and Rock-type Pokémon and moves, although a Rock-type would be preferred to protect against most of its attacks.
You can choose a variety of choices when battling Ho-oh, but your best options would be to use Rhyperior, Alola Golem, and Gigalith against it.
Rhyperior is an excellent Ground and Rock-type Pokémon. While it has several weaknesses, Ho-oh has none of them to use against it, making Rhyperior and superior choice. It has a maximum CP of 3,733, an attack of 241, a defense of 190, and stamina of 251. When picking a Rhyperior to take with you, want to make sure it knows smack down and rock wrecker, mud slap and rock wrecker, and smack down and earthquake. The rock wrecker move was only available during Rhyhorn’s Community Day, or if you have an Elite TM for Charge Moves, so it might be harder to find one that knows it.
Your next choice is Alola Golem, which is an Electric and Rock-type Pokémon. It’s the best of both worlds to devastate Ho-oh and is an excellent choice to withstand many of its attacks. It has a maximum CP of 2,949, an attack of 211, a defense of 198, and stamina of 190. You want your Alola Golem to know rock throw and wild charge or volt switch and wild charge. An Alola Golem can also learn rock throw and stone edge, but it doesn’t produce as much damage as the other two choices.
The final optimal option is to go with Gigalith. It’s purely a Rock-type Pokémon, with a maximum CP of 3,228, an attack of 226, a defense of 201, and stamina of 198. It’s a great fighter against Ho-oh, capable of withstanding any of its Flying and Fire-type attacks. It can deal plenty of damage, too. You want to use one that knows smack down and rock slide or mud slap and rock slide. Those are the best attacks it can know, whereas the other combinations fall pretty short of being useful against Ho-oh.
Should you not have any of the above listed Pokémon, there are plenty of other choices. You can always take Rampardos, Terrakion, Aggron, Omastar, Aerodactyl, Darmanitan, Zapdos, Crustle, Empoleon, or Magnezone. Those are some of the many choices you can take with you during a Ho-oh raid. You will have a chance to capture Ho-oh after you defeat it, and you receive many premier Poké Balls depending on your participation, how many friends were in the battle, and if the Gym had been owned by your team.
