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 Pokémon HOME transfer to obtain in Violet.
Acquiring Deino:
Deino can be 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 for access to the former. Three-star Tera Raids also offer Deino encounters, potentially with Hidden Abilities and varying Tera Types. Zweilous, Deino's evolution, appears in four-star Tera Raids and in the wild locations mentioned above. Five and six-star Tera Raids provide Hydreigon encounters.
Transferring Deino to Pokémon Violet:
To obtain Deino in Pokémon Violet, utilize Pokémon HOME. Transfer Deino from compatible games (Sword/Shield, GO, or Scarlet) to your HOME Basic Box. Then, open Pokémon Violet within HOME and transfer Deino to a PC Box. Alternatively, utilize the Union Circle (requires Nintendo Switch Online Membership) for trading.
Evolving Deino:
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 base stat total of 600, excelling in Special Attack and Attack with good Speed. A Timid or Jolly Nature enhances its Speed.
- Type Effectiveness:
- Super Effective Against: Dragon, Ghost, Psychic
- Weaknesses: Fairy (4x), Fighting, Bug, Dragon, Ice
- Resistances: Grass, Water, Fire, Electric, Ghost, Dark
- Immunities: Ground, Psychic
Hydreigon's significant weakness to Fairy-type moves necessitates a Steel-type move in its moveset; Flash Cannon (TM) is a viable option. A Special Attack-focused Hydreigon, utilizing moves like Nasty Plot, Dragon Pulse (or Draco Meteor), and Dark Pulse, is generally recommended. Terastallizing allows for strategic type changes to mitigate weaknesses or gain STAB bonuses.
