This guide details how to obtain and utilize Hydreigon, a powerful Dark/Dragon-type Pokémon in Pokémon Scarlet and Violet. Hydreigon's pre-evolutions, Deino and Zweilous, are exclusive to Pokémon Scarlet, requiring trading or transferring to acquire them in Pokémon Violet.
Acquiring Deino and Zweilous:
Deino and 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 (35-40) reside in Alfornada Cavern and Dalizapa Passage. They can also be encountered in 3-star (Deino) and 4-star (Zweilous) Tera Raids. These raid encounters offer the possibility of obtaining Deino with its Hidden Ability.
To obtain Deino in Pokémon Violet, trading via the Union Circle (requires Nintendo Switch Online) or transferring from Pokémon HOME (compatible with Pokémon Sword/Shield, Pokémon GO, and Pokémon Scarlet) is necessary.
- Pokémon HOME Transfer: Move Deino from your source game to the Basic Box in HOME. Then, open Pokémon Violet and transfer it to a PC Box.
Evolution:
Deino evolves into Zweilous at level 50, and Zweilous evolves into Hydreigon at level 64. Utilize auto-battling or Exp. Candies (L and XL recommended) to expedite the evolution process.
Hydreigon's Strengths and Weaknesses:
Hydreigon boasts a 600 base stat total, excelling in Special Attack and Attack with good Speed. A Timid or Jolly Nature is recommended.

Terastallizing mitigates Hydreigon's 4x weakness to Fairy-type moves. Its movepool allows for both physical and special attacking strategies. Flash Cannon (via TM) is a crucial Steel-type move to counter Fairy-type threats. Other recommended moves include Nasty Plot, Dragon Pulse (or Draco Meteor), and Dark Pulse. Consider its weaknesses when strategizing team composition.
