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 obtain them in Pokémon Violet.
Acquiring Deino and Zweilous:
- Pokémon Scarlet: Find Deino in 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. Zweilous can also be found in these locations, as well as in 4-star Tera Raids (requires 3 gym badges). Deino can also be found in 3-star Tera Raids.
- Pokémon Violet: Due to version exclusivity, you must trade for Deino from a Pokémon Scarlet player via the Union Circle (requires Nintendo Switch Online) or transfer it from Pokémon HOME. Pokémon HOME allows transfers from Pokémon Sword/Shield, Pokémon GO, and Pokémon Scarlet. Instructions for transferring from HOME are provided below.
Transferring Pokémon from HOME:
- Open Pokémon HOME and move Deino from your source game to your Basic Box. Save and exit.
- In HOME, select Pokémon Violet and transfer Deino from the Basic Box to a PC Box. Save and exit.
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 leveling process.
Hydreigon's Strengths and Weaknesses:
Hydreigon, a pseudo-legendary Pokémon, boasts a base stat total of 600, excelling in Special Attack and Attack with good Speed. A Timid (+Speed, -Attack) or Jolly (+Speed, -Special Attack) Nature is recommended.

Hydreigon's 4x weakness to Fairy-type moves can be mitigated through Terastallization. Its movepool allows for both physical and special attacking strategies. Consider moves like Nasty Plot, Dragon Pulse (or Draco Meteor), Dark Pulse, and Flash Cannon (Steel-type via TM) to counter its Fairy weakness.
