This guide details how to obtain and utilize Hydreigon, a powerful Dark/Dragon-type Pokémon in Pokémon Scarlet and Violet. Hydreigon's evolution line (Deino and Zweilous) is exclusive to Pokémon Scarlet, requiring trading or transferring to obtain it in Pokémon Violet.
Acquiring Deino:
Deino and its evolution, Zweilous, are found in several locations within Pokémon Scarlet: Alfornada Cavern, Dalizapa Passage, Glaseado Mountain, Area Zero, and North Province (Area Two). Higher-level Deino (levels 35-40) reside in Alfornada Cavern and Dalizapa Passage, requiring Koraidon's high jump ability to access the former. Three-star Tera Raids also offer Deino, potentially with its Hidden Ability, and four-star raids feature Zweilous. Five and six-star raids offer Hydreigon itself.
Transferring Deino to Pokémon Violet:
Since Deino is Scarlet-exclusive, transferring to Violet is necessary. This can be achieved through Pokémon HOME, requiring the HOME app on your Nintendo Switch. Transfer is possible from Pokémon Sword/Shield, Pokémon GO, and Pokémon Scarlet. The steps are:
- Move Deino from your source game to your Basic Box in Pokémon HOME. Save and exit.
- Open Pokémon Violet in HOME and transfer Deino from the Basic Box to a PC Box. Save and exit.
Alternatively, trading via the Union Circle (requires Nintendo Switch Online) is an option.
Evolution:
Deino evolves into Zweilous at level 50, and Zweilous evolves into Hydreigon at level 64. Exp. Candy L and XL are recommended for faster leveling. Auto-battling can also expedite the process.
Hydreigon's Strengths and Weaknesses:
Hydreigon boasts a base stat total of 600, excelling in Special Attack and Attack with good Speed. A Timid or Jolly Nature is recommended.
-
Type Effectiveness: Super-effective against Dragon, Ghost, and Psychic types. Weaknesses include Fairy (4x), Fighting, Bug, Dragon, and Ice types. Resists Grass, Water, Fire, Electric, Ghost, and Dark types. Immune to Ground and Psychic.
-
Strategy: Hydreigon's double weakness to Fairy is mitigated by Terastallizing. Its movepool allows for both physical and special attacking strategies. A special attacker build is generally preferred due to its lack of strong physical Steel-type moves; Flash Cannon (via TM) is crucial for countering Fairy types. Other recommended moves include Nasty Plot, Dragon Pulse (or Draco Meteor), and Dark Pulse.
