Deino Evolution Revealed: Discover the Secrets of Hydreigon's Lineage

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, necessitating trading or transferring methods for Pokémon Violet players.

Acquiring Deino:

• Pokémon Scarlet: Deino can be found in the 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. Koraidon's high jump ability is needed for Alfornada Cavern. Three-star Tera Raids also offer Deino, potentially with its Hidden Ability.
• Pokémon Violet: Due to version exclusivity, trading via the Union Circle (requires Nintendo Switch Online) or transferring through Pokémon HOME from Pokémon Scarlet, Sword/Shield, or Pokémon GO is necessary. Pokémon HOME instructions:
  1. Move Deino to your Basic Box in Pokémon HOME.
  2. Open Pokémon Violet in HOME and transfer Deino to a PC Box.

Deino and Zweilous Locations:

• Deino: Alfornada Cavern, Dalizapa Passage, Glaseado Mountain, Area Zero, North Province (Area Two), and 3-star Tera Raids.
• Zweilous: Dalizapa Passage, Area Zero, Alfornada Cavern, and 4-star Tera Raids.
• Hydreigon: 5/6-star Tera Raids.

Terastallizing mitigates Hydreigon's 4x weakness to Fairy. Flash Cannon (TM) is a crucial Steel-type move. Other recommended moves include Nasty Plot, Dragon Pulse (or Draco Meteor), and Dark Pulse. Consider Hydreigon's movepool to determine its role as a physical or special attacker.
