Hydreigon, the formidable Dark/Dragon-type Pokémon, stands as one of the most powerful creatures in Pokémon Scarlet & Violet. Trainers eager to add this pseudo-legendary to their Pokédex should first acquire its pre-evolutions: Deino and Zweilous. Evolving the Irate Deino into the Brutal Hydreigon is a rewarding journey, but it's important to note that Deino and its evolutions are exclusive to Pokémon Scarlet. Players of Pokémon Violet will need to utilize trading or other methods to obtain them.
Updated January 13, 2025 by Renri Seong: The Deino line, introduced in Gen 5's Pokémon Black/White, continues its appearance in mainline titles, including Pokémon Scarlet & Violet. As with many new generation introductions, Deino and its evolutions are version-exclusive. While readily available in the wild within Pokémon Scarlet, acquiring one in Pokémon Violet requires trading or transferring.
Where to Catch Deino in Pokémon Scarlet
Deino and Zweilous Locations
In Pokémon Scarlet, Deino can be found in Alfornada Cavern, Dalizapa Passage, Glaseado Mountain, Area Zero, and North Province (Area Two). While Glaseado Mountain, Area Zero, and North Province (Area Two) offer easier access, Alfornada Cavern and Dalizapa Passage present a more challenging but rewarding hunt. Deino in Dalizapa Passage and Alfornada Cavern range from levels 35-40.
- Alfornada Cavern: Located in the southwest corner of the Paldea map, requiring Koraidon's high jump ability.
- Dalizapa Passage: Accessible east from Medali or west from Zapapico; situated between these locations on the map.
Three-star Tera Raids (unlocked after obtaining three Gym Badges) also offer Deino encounters, potentially with different Tera Types and a chance of possessing its Hidden Ability. Zweilous, Deino's evolution, appears in the wild in Dalizapa Passage, Area Zero, and Alfornada Cavern, and also in four-star Tera Raids. Hydreigon can be found in 5/6-star Tera Raids.

As a Dark/Dragon-type, Hydreigon is super-effective against Dragon, Ghost, and Psychic types. However, it has a 4x weakness to Fairy, and weaknesses to Fighting, Bug, Dragon, and Ice. It resists Grass, Water, Fire, Electric, Ghost, and Dark types, and is immune to Ground and Psychic. Terastallizing mitigates the double Fairy weakness. Offensively, adjusting its Tera Type allows for STAB on moves like Flash Cannon (learnable via TM). Its diverse movepool allows for both physical and special attacking strategies. Recommended moves include Nasty Plot, Dragon Pulse (or Draco Meteor), and Dark Pulse. A Steel-type move, ideally Flash Cannon, is crucial to counter its Fairy weakness.
