Although some Pokemon GO players are unhappy with Ho-Oh and Latias/Latios appearing at the same time; there are still level 5 Battle Raids that need to be defeated. Players should be well aware of the differences between battling Latios and Latias, but many trainers may need a refresher on Ho-Oh's weaknesses.
Ho-Oh is a powerful Legendary Battle Raid boss, so Pokemon GO raiders need to bring a strong team to the table to be able to defeat it. Although the weaknesses are similar to Moltres', things are more difficult because Ho-Oh has a chance to spawn with Solar Beam. That move is a serious risk for Rock and Water types, so be ready to dodge.
Lots of research and simulations have been done by the trainers at Pokemon GO Hub, so there is a ton of data to help prepare for this fight. Here are the strongest counters that we recommend...
Rock
Golem - Equipped with Rock Throw and Stone Edge
Tyranitar - Equipped with Bite and Stone Edge
Omastar - Equipped with Rock Throw and Rock Slide
Electric
Zapdos - Equipped with Charge Beam and Thunderbolt
Raikou - Equipped with Charge Beam and Wild Charge
Water
Kyogre - Equipped with Waterfall and Hydro Pump. (Avoid using when Ho-Oh spawns with Solar Beam)
Additional Options
Rayquaza - Equipped with Dragon Tail and Ancient Power
Jolteon - Equipped with Thunder Shock and Thunder Bolt
This fight is no joke, so hopefully trainers have some of these heavy hitters ready to go, or at least a big group to work with.
Ho-Oh has a base 2% catch rate, so it may take a few raids to actually catch this Legendary. For players hoping to secure a shiny, that could obviously take dozens of raids and a good amount of luck.
So far, Niantic has not announced which Legendary will appear next after Ho-Oh, Latias, and Latios have finished their rotations. We'll be sure to update once that information is public.
Until then, good luck out there trainers!
