Dark/Dragon-type Hydreigon has proven to be one of the most powerful Pokemon in all ofPokemon Scarlet & Violet, and trainers will most certainly want to add it to their Pokedex. It’s recommended that you first obtain Hydreigon’s pre-evolved forms: Deino and Zweilous. From there, you can evolve the Irate Deino into the Brutal Hydreigon. However, you’ll notice that Deino and its evolutions can only be found inPokemon Scarlet. To get them intoPokemon Violet, you’ll have to use other methods.

Thanks to Terastallizing, Hydreigon can shed its debilitating double weakness to Fairy-type moves. Offensively, players canchange its Tera Typeto get STAB on powerful moves like Flash Cannon. If you use it for offense, then Hydreigon can function as a physical attacker or a special attacker. Hydreigon’s learnset is a mix of physical and special moves, so it’s up to you what to choose.
However, since Hydreigon has a glaring weakness to Fairy-type moves, you should make sure it has a Steel-type move.Flash Cannonis the only Steel-type move it can learn via TM. Unfortunately, it can’t learn any physical Steel-type moves,so you may learn towards a special attackerHydreigon over a physical attacker Hydreigon. Other recommended moves areNasty Plot(to sharply raise Special Attack),Dragon Pulse(orDraco Meteor), andDark Pulse.
