Unleash the Enigma: Capturing and Evolving Deino in Pokémon

This guide details how to obtain and utilize the powerful Dark/Dragon-type Pokémon, Hydreigon, in Pokémon Scarlet and Violet. Hydreigon, a pseudo-legendary Pokémon, boasts impressive stats and is a valuable asset to any team. However, its evolutionary line (Deino and Zweilous) is exclusive to Pokémon Scarlet, necessitating trading or transferring methods for Pokémon Violet players.

Acquiring Deino:

In Pokémon Scarlet:

Deino and its evolution, Zweilous, can be found in several locations: 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 jump ability is required for Alfornada Cavern. Additionally, Deino can be obtained from 3-star Tera Raids (post-3 gym badges), offering a chance for a Hidden Ability variant. Zweilous appears in 4-star Tera Raids. Hydreigon can be found in 5/6-star Tera Raids.

In Pokémon Violet:

Since Deino is Scarlet-exclusive, trading via the Union Circle (requires Nintendo Switch Online) or transferring through Pokémon HOME is necessary. Pokémon HOME allows transferring from Pokémon Sword/Shield, Pokémon GO, and Pokémon Scarlet. The process involves moving Deino to your HOME Basic Box, then transferring it to your Pokémon Violet PC Box.

Evolution:

Deino evolves into Zweilous at level 50, and Zweilous evolves into Hydreigon at level 64. Utilize auto-battling or Exp. Candies (especially L and XL) to expedite the leveling process.

Hydreigon's Strengths and Weaknesses:

Hydreigon's 600 base stat total, high Special Attack and Attack, and good Speed make it a formidable Pokémon. A Timid or Jolly nature is recommended.

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

Terastallizing mitigates Hydreigon's 4x weakness to Fairy-type moves. Its movepool allows for both physical and special attacking styles. However, due to its Fairy weakness, learning Flash Cannon (via TM) is highly recommended. Other suggested moves include Nasty Plot, Dragon Pulse (or Draco Meteor), and Dark Pulse.
