Pokémon GO Dynamax Beldum Weaknesses & Counters

screenrant.com:

Dynamax Beldum is the latest Max Raid Boss to appear in as part of the Psychic Spectacular event. As well as being able to battle this Steel/Psychic-type creature, you'll also get the chance to catch it and evolve it into the powerful Metagross. Before you can do that, though, you'll need to know its weaknesses and the best counters to take it down.

Following in the footsteps of Bulbasaur, Charmander, Squirtle, Skwovet, and Wooloo, Beldum is now appearing in Max Battles located at Power Spots across the map. Its final evolution, Metagross, is an imposing pseudo-Legendary Pokémon that's one of the best attackers for Raid Battles, so having a Dynamax-capable version in your collection is sure to come in handy for future Max Battles.

Dynamax Beldum has four weaknesses that you can target: Dark, Fire, Ghost, and Ground-type attacks. None of these attack types are more effective than another, so use whichever one you have access to. Remember that only Dynamax Pokémon can enter Max Battles, and you're allowed three on your team, so your options are going to be quite limited.

There aren't many Dynamax Pokémon available in right now, but fortunately, there's one excellent Beldum counter that you might already have in your collection: Dynamax Charmander. This fan-favorite starter Pokémon has been appearing in Max Raid Battles since the GO Big event on September 10, 2024. If you don't have one yet, try looking for a Max Raid featuring Dynamax Charmander on the map. Defeat it in battle, and you'll get a chance to catch it.

Max Raids are hosted in Power Spots, which appear as glowing purple icons on the map. You can also check the Nearby feature and scroll across to the Power Spots tab to see Max Battles that are within reach of your current location.

Considering that Dynamax Beldum is the first Three-Star Max Raid Boss in the game and will be a more difficult opponent than previous Max Raid Bosses you've faced, it would be a good idea to fully evolve your Dynamax Charmander
