## Biology

Hydreigon is a three-headed, draconic Pokémon with six thin, black wings that each end in two points on its back. It has a fuchsia-colored collar on its neck which surrounds its head. The main head is dark blue and has black eyes with fuchsia pupils. Its two hands are also black and each one harbors a head; these are similarly blue with black eyes with small fuchsia collars on the inside. Its abdomen has two fuchsia stripes and its feet appear atrophied, having no claws or defined soles and two or three small toes. Its tail also sports a fuchsia stripe and ends with a black tuft.

Hydreigon is a violent, destructive Pokémon. It will attack anything that moves, determining it a foe. Its heads can consume anything. Many stories describe Hydreigon destroying entire villages. Despite its three heads, it is a singular entity, unlike its pre-evolution Zweilous; its secondary heads lack brains, and do not move or think of their own accord.

### Major appearances

Hydreigon debuted in *White—Victini and Zekrom* and *Black—Victini and Reshiram*, under the ownership of Carlita. It was first used during the Harvest Battle Tournament, and later during a battle against Ash's Tepig, who was powered up by Victini at the time. It then provided aerial transport for Carlita for the rest of the movies. In the former movie, Hydreigon is Shiny.

Hydreigon made its main series debut in *Iris and the Rogue Dragonite!*. It was seen battling a wild Dragonite and injured it in the process.

A Hydreigon appeared in *A Village Homecoming!*, under the ownership of Shannon, having evolved from one of the two Zweilous she was raising. Soon after evolving, Hydreigon went on a rampage, but it later calmed down thanks to Iris's efforts. It reappeared in a flashback in *Best Wishes Until We Meet Again!*.

A Hydreigon appeared in *Strong Strategy Steals the Show!* and *Cameron's Secret Weapon!*, under the ownership of Cameron. Hydreigon proved powerful in its battle against Ash, managing to defeat Boldore and Oshawott before losing to Pignite. Cameron later used Hydreigon during his match against Virgil in *A Unova League Evolution!*, where it was shown on the scoreboard as being defeated.

### Minor appearances

A Trainer's Hydreigon appeared in *A Relay in the Sky!*, where it was seen competing in the Pokémon Sky Relay. It was in a team also consisting of Masquerain and Butterfree.

A Trainer's Hydreigon appeared in a flashback in *Valuable Experience for All!*, where it was seen being defeated by Remo's Mega Garchomp in the Lumiose Conference.

### In the movie adaptations

Hydreigon appeared in *White—Victini and Zekrom* under the ownership of Carlita.

### In the Pokémon Adventures manga

Ghetsis used his Hydreigon to fly to Dragonspiral Tower to meet N in *The Battle Within*. It was later used in a battle against Black.

## Other appearances

### Super Smash Bros. for Wii U

Hydreigon appears in the background of the Kalos Pokémon League stage when the stage is in the Dragonmark Chamber. It appears alongside Dragonite, Garchomp, and Axew.

#### Trophy information

**NA:** *Unlike Scizor with its pretend heads, Hydreigon's three heads are real! The center head is the brains of the operation, while the left and right ones are there to consume everything they can. We wouldn't be surprised to see Hydreigon at an eating contest, but there has to be a rule against having three mouths on one body...?*

**PAL:** *Unlike Scizor's head-like claws, the heads at the end of Hydreigon's arms are the real deal. Only the head in the middle does any thinking - the other two are just for gobbling up anything in sight. If you think about it, Hydreigon would probably win any eating contest hands down, but... maybe having three mouths is against the rules...*

## Game data

### NPC appearances

* Pokémon Mystery Dungeon: Gates to Infinity: Hydreigon was at first described by Munna as an evil Pokémon who is pure destruction in Pokémon form, devours everything in his path, and said to be the cause of the world's balance being disrupted. In truth, Munna's words about him were all a lie to trick the player, and Hydreigon is really the physical embodiment of the Voice of Life, the form of the world's will to live, who called upon humans to save the Pokémon world as no Pokémon could hope to save it. He originally first contacted the player through a dream before Munna intercepted the vision, and by using Hydreigon's voice, she tricked the player into thinking Hydreigon was evil.

## Trivia

* Hydreigon evolves from its pre-evolved form starting at the highest level of all Pokémon that evolve by leveling up, at level 64.
* According to interviews with Ken Sugimori in *Nintendo Dream*, Hydreigon and its evolutionary family were originally intended to be cyborg dragons with aspects of tanks. The Pokémon were scrapped until late in development, when they were revived and remade to be based on Yamata no Orochi. The tank tread-like markings on Hydreigon's body are a remnant of this design.
	+ Although Yamata no Orochi typically has eight heads in mythology, Hydreigon was designed with fewer heads to appear less confusing.
* Hydreigon shares its category with Sharpedo. They are both known as the Brutal Pokémon.
* Hydreigon has the highest base Special Attack stat of all pseudo-legendary Pokémon.
* Hydreigon is the only pseudo-legendary Pokémon to have Dragon as its secondary type rather than its primary type, the only pseudo-legendary Pokémon without a Hidden Ability, and the only pseudo-legendary with a single Ability.

### Origin

Hydreigon is based on the Yamata no Orochi, including its red eyes. Its three heads and Shiny coloration resemble the Zmey Gorynych. It may also incorporate elements of the Lernaean Hydra. These mythological serpents may have inspired Hydreigon's Dark typing, as all three are deadly antagonists, with the Zmey Gorynych in particular shown to be deceptive. The markings on its body are based on tank treads, referencing its destructive nature.

#### Name origin

Hydreigon may be a combination of *hydra*, *drei* (German for *three*), and *dragon*. It may also incorporate hydrogen, a gas highly flammable under normal conditions.

Sazandora may be a combination of 三 *san* (three) and *dragon* or *hydra*.
