Hydreigon (JP) is a species of Pokémon in the series of the same name. It is a dual-type Dark/Dragon Pseudo-legendary Pokémon that made its first appearance in the fifth Pokémon generation in the Black and White games. It evolves from Zweilous starting at level 64. Its Paradox counterpart is Iron Jugulis.

Physiology and Behavior[]

Hydreigon is a three-headed, draconic Pokémon with six thin, black wings that each end in two points on its back. Its body is primarily dark blue, with black fur covering its necks and shoulders. The inner fur surrounding its heads is fuchsia in color, and resembles collars. Hydreigon's heads have black eyes; the main head additionally has fuchsia pupils and visible pointed teeth, while the secondary head's eyes are simplistic and unable to blink. Its abdomen has two fuchsia stripes and its feet appear atrophied, having no claws or defined soles. 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. However, the anime has depicted Hydreigon as being fairly obedient when around its Trainer. The three heads take turns when attacking, not stopping until their target is defeated. Hydreigon can also use its three mouths to rapidly eat through anything. Despite its three heads, it is a singular entity, unlike its pre-evolved form Zweilous; its secondary heads lack brains and do not move or think of their own accord. Conversely, with its central head housing its brain, Hydreigon is said to be highly intelligent in spite of its constantly destructive thoughts. Hydreigon lives high up in the air and has been known to ambush opponents from above. Many stories described Hydreigon destroying entire villages. However, Hydreigon is afraid of Noivern during nighttime. It is said Hydreigon's reason for being ferocious is due to ancient people loathing it. The ancient people believed Hydreigon was evil incarnate, hence always attacking it.

Iron Jugulis shares a resemblance to Hydreigon. The reason is believed due to it being a possibly futuristic hybrid made from combining Hydreigon and machines together as one. It is also rumoured that Iron Jugulis is the child of a Hydreigon which fell in love with a machine.

Appearances[]

Main Pokémon games[]

Pokémon spin-offs[]

In PokéPark 2: Wonders Beyond, Hydreigon and Haxorus kidnap Victini at the Crag Area and take him to Wish Park, but are defeated by the player.

In 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.

Super Smash Bros.[]

In Super Smash Bros. for Nintendo 3DS and Wii U and Super Smash Bros. Ultimate, Hydreigon appears in the background of the Kalos Pokémon League stage when the stage is in the Dragonmark Chamber. It appears alongside Axew, fellow Pseudo-legendary Pokémon Dragonite, and Garchomp. Hydreigon appeared as a Spirit in Ultimate.

In the anime[]

Origin[]

Hydreigon is based on Yamata no Orochi, a red-eyed, eight-headed dragon or serpent from Japanese mythology. However, compared to Yamata no Orochi, Hydreigon was designed with fewer heads to appear less off-putting, although its wings were designed as a nod to the Orochi's additional heads. Its three heads and Shiny coloration also resemble the Zmei Gorynych, a cunning and deceptive dragon or serpent in Slavic folklore with green scales and a head count of three or its multiples. The tank tread-like markings on Hydreigon's body appears to be a remnant of when Hydreigon's evolutionary line were originally designed after tanks. The presence of smaller heads on top of its arms makes them reminiscent of hand puppets.

Hydreigon may also incorporate elements from other many-headed antagonistic dragons or serpents in various mythologies, such as the Lernaean Hydra, Zahhak, or the Yelbeghen.

Hydreigon evolving at level 64 could be a reference to 1964, the year that the fifth film in the Godzilla franchise, Ghidorah, the Three-Headed Monster, was released.

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.
  • Hydreigon has the highest base Special Attack stat of all Pseudo-legendary Pokémon.
    • Hydreigon is one of the two Pseudo-legendary Pokémon with a higher Special Attack stat than Attack, the other is Goodra.
  • Hydreigon is the only pseudo-legendary Pokémon to have a single Ability.
