Hydreigon, the Dark/Dragon-type pseudo-legendary Pokémon, remains one of the most formidable additions to any trainer's team in Pokémon Scarlet & Violet. With impressive stats and versatile move options, it's a must-have for competitive players and story completers alike. To fully harness its potential, trainers should first acquire its pre-evolutions—Deino and Zweilous—and evolve them accordingly.

Please note that Deino and its evolutionary line are exclusive to Pokémon Scarlet. Players looking to add this powerful trio to their Violet game will need to engage in trading or transfer methods.

Hydreigon made its debut in Generation 5 with Pokémon Black/White, and since then has remained a staple in main series games. In Scarlet & Violet, the Deino evolutionary line continues its legacy as a strong pseudo-legendary Pokémon. While Scarlet players can find it in the wild, those playing Violet must trade or transfer to obtain it. This guide explores how to catch Deino, evolve it into Hydreigon, and evaluate its effectiveness in battle.

Where to Catch Deino in Pokémon Scarlet

Deino and Zweilous Locations

In Pokémon Scarlet, you can encounter wild Deino in the following areas:

• Alfornada Cavern
• Dalizapa Passage
• Glaseado Mountain
• Area Zero
• North Province (Area Two)

The highest-level Deino spawns occur between levels 35–40 in Alfornada Cavern and Dalizapa Passage. These two locations require specific traversal techniques—Koraidon's high jump ability may be necessary for navigating Alfornada Cavern.

Additionally, Deino can appear in 3-star Tera Raids, which become available after earning three gym badges. Tera Raid versions of Deino may feature different Tera Types and potentially have their Hidden Ability.

Zweilous, Deino's evolved form, can also be found in the wild at Dalizapa Passage, Area Zero, and Alfornada Cavern. You can also encounter Zweilous in 4-star Tera Raids.

For those aiming to challenge Hydreigon directly, it appears in 5 and 6-star Tera Raids.

How to Get Deino in Pokémon Violet

How to Trade and Transfer

Since Deino is exclusive to Pokémon Scarlet, obtaining it in Violet requires either trading or transferring from another compatible title. Here's how:

Option 1: Trade via Union Circle (Requires Nintendo Switch Online Membership)

Use the Union Circle feature to connect with other players and trade for a Deino.

Option 2: Transfer using Pokémon HOME

This method allows you to transfer Deino from the following sources:

• Pokémon Sword/Shield
• Pokémon GO (via mobile app)
• Pokémon Scarlet

Steps to Transfer Using Pokémon HOME:

1. Open the Pokémon HOME app on your Nintendo Switch.
2. Select the source game where Deino is located.
3. Move Deino to your Basic Box and save.
4. Open Pokémon Violet within HOME and transfer Deino from the Basic Box to a PC Box.
5. Save and exit to complete the transfer.

How to Evolve Deino into Zweilous and Hydreigon

What Level Does Deino Evolve?

Evolving Deino follows a straightforward level-based path:

• Deino → Zweilous at Level 50
• Zweilous → Hydreigon at Level 64

To speed up the process, use the auto-battle function against large groups of Pokémon, feed Exp. Candies (especially Exp. Candy L and XL), or carry Rare Candies.

Hydreigon Stats & Weaknesses

As a pseudo-legendary Pokémon, Hydreigon boasts a total base stat of 600, making it one of the strongest contenders in Pokémon Scarlet & Violet.

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

Thanks to Terastallization, Hydreigon can change its type to reduce vulnerability—especially useful for mitigating the 4x weakness to Fairy-types. As a dual-typed Dark/Dragon, it benefits from moves like Nasty Plot, Dragon Pulse, Dark Pulse, and Flash Cannon (learned via TM).

While it lacks physical Steel-type moves, its special attack stat makes a special attacker build more effective. Recommended Natures include Timid (+Speed, -Attack) or Jolly (+Speed, -Special Attack) for optimal performance.
