Heavy Metal Pokemon is not, in fact, a very specific genre of music. Instead, it's a special ability certain Pokémon can use during battles, and it's making an appearance in the upcoming Pokémon Sword and Shield. Here's what you need to know about it.
Heavy Metal in Pokémon Sword and Shield: What You Need to Know
Heavy Metal is an ability that was introduced in Pokémon White and Black available only to certain Steel-type Pokémon. The ability let those Pokémon double their own weight, making Heavy Slam and Heat Crash more powerful attacks but increasing the Pokémon's vulnerability to Low Kick and Grass Knot. It also made Heavy Slam and Heat Crash deal less damage to the now-heavier Pokémon.
Aron, Lairon, Aggron, Bronzor and Bronzong have all had the Heavy Metal ability in the past. Duraludon, one of the new Pokémon revealed for Pokémon Sword and Shield, will be the first to have both Heavy Metal and its inverse Light Metal as abilities.
Duraludon's other in-battle abilities remain unknown.
