Dark/Dragon-type Hydreigon stands out as one of the most formidable Pokémon in Pokémon Scarlet & Violet, making it a must-have for any serious trainer's Pokédex. To harness its power, you'll first need to capture its pre-evolved forms, Deino and Zweilous. These can be evolved into the fearsome Hydreigon. However, it's important to note that Deino and its evolutions are exclusive to Pokémon Scarlet. If you're playing Pokémon Violet, you'll need to explore alternative methods to obtain them.
Updated January 13, 2025 by Renri Seong: The Dark/Dragon-type Deino evolves into the powerful pseudo-legendary Hydreigon. Introduced in Gen 5 with Pokémon Black/White, the Deino line has been a staple in mainline titles, including Pokémon Scarlet/Violet. As with many new generations, Deino and its evolutions are version-exclusives. You can catch them in the wild in Pokémon Scarlet, but you'll need to trade to get one in Pokémon Violet. With a variety of pseudo-legendaries available in Scarlet/Violet, you might wonder if Hydreigon is still worth using. This guide has been updated to include new information about Hydreigon, such as its stats and type effectiveness.
Where to Catch Deino in Pokémon Scarlet
Deino and Zweilous Locations
In Pokémon Scarlet, you can find Deino in several locations: Alfornada Cavern, Dalizapa Passage, Glaseado Mountain, Area Zero, and North Province (Area Two). Glaseado Mountain, Area Zero, and North Province (Area Two) are easily accessible, while Alfornada Cavern and Dalizapa Passage are a bit more hidden. Deino in Dalizapa Passage and Alfornada Cavern range from levels 35 to 40.
- Alfornada Cavern: Located in the southwest corner of the Paldea map, you'll need Koraidon's high jump ability to navigate the cave.
- Dalizapa Passage: Accessible by heading east from Medali or west from Zapapico. It's the area between these two locations on the map.
You can also encounter Deino in 3-star Tera Raids, which become available after earning 3 gym badges. Deino from these raids may have a different Tera Type and a chance of having their Hidden Ability.
Zweilous, Deino's evolved form, can be found in the wild at Dalizapa Passage, Area Zero, and Alfornada Cavern. Like Deino, Zweilous can also be obtained from Tera Raids, specifically 4-star Tera Raids.
Hydreigon can be caught in 5/6-star Tera Raids.
How to Get Deino in Pokémon Violet
How to Trade and Transfer
Since the Deino line is exclusive to Pokémon Scarlet, you'll need to trade or transfer Deino to obtain it in Pokémon Violet. For trading, a Nintendo Switch Online Membership is required to use the Union Circle. If you prefer not to subscribe, consider using Pokémon HOME to transfer Deino from another game to Pokémon Violet.
To transfer using HOME, you'll need the HOME app on your Switch. Deino and its evolutions can be transferred from Pokémon Sword/Shield, Pokémon GO, and Pokémon Scarlet.
- Open Pokémon HOME, select the game from which you have Deino, and move it to your Basic Box. Then, save and exit.
- While still in HOME, open Pokémon Violet and move Deino from the Basic Box to a PC Box. Save and exit.
How to Evolve Deino into Zweilous and Hydreigon
What Level Does Deino Evolve?
Deino evolves into Zweilous at level 50, and Zweilous evolves into Hydreigon at level 64. To speed up the leveling process, you can have Deino/Zweilous auto-battle large groups of Pokémon. Alternatively, you can use Exp. Candies or Rare Candies. Exp. Candy L and Exp. Candy XL are particularly effective due to Deino's high evolution levels.
Is Hydreigon a Good Pokémon?
Hydreigon Stats & Weaknesses
As a pseudo-legendary, Hydreigon ranks among the strongest Pokémon in Pokémon Scarlet & Violet. Its base stat total is 600, with high Special Attack and Attack, and good Speed. This makes it versatile, suitable for both physical and special attack strategies. A Timid (+Spd, -Attk) or Jolly (+Spd, -Sp.Attk) Nature can enhance its performance.
| HP: | 92 |
|---|---|
| Attack: | 105 |
| Special Attack: | 125 |
| Defense: | 90 |
| Special Defense: | 90 |
| Speed: | 98 |
| Total: | 600 |
As a Dark/Dragon-type, Hydreigon has the following 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 Terastallizing, Hydreigon can mitigate its double weakness to Fairy-type moves. Offensively, changing its Tera Type can provide STAB on powerful moves like Flash Cannon. Hydreigon's move set includes both physical and special moves, allowing flexibility in its role as an attacker.
Given Hydreigon's significant weakness to Fairy-type moves, equipping it with a Steel-type move like Flash Cannon, which it can learn via TM, is advisable. Other recommended moves include Nasty Plot to boost Special Attack, Dragon Pulse (or Draco Meteor), and Dark Pulse.
