Deino Debut: A Guide to Capturing and Evolving in Pokémon Scarlet & Violet

This guide details how to obtain and utilize Hydreigon, a powerful Dark/Dragon-type Pokémon in Pokémon Scarlet & Violet. Hydreigon's pre-evolutions, Deino and Zweilous, are exclusive to Pokémon Scarlet, necessitating trading or transferring to obtain them in Pokémon Violet.

Acquiring Deino and Zweilous:

Pokémon Scarlet: Locate Deino in the 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. Zweilous can also be found in these locations, and both Pokémon appear in Tera Raids (3-star for Deino, 4-star for Zweilous).
Pokémon Violet: Due to version exclusivity, trading via the Union Circle (requires Nintendo Switch Online) or transferring from Pokémon HOME (compatible with Pokémon Sword/Shield, Pokémon GO, and Pokémon Scarlet) are necessary. The HOME transfer process involves moving Deino to your HOME Basic Box, then transferring it to your Pokémon Violet PC Box.
