Zweilous (Japanese: ジヘッド Dihead) is a dual-type Dark/Dragon Pokémon introduced in Generation V.

It evolves from Deino starting at level 50 and evolves into Hydreigon starting at level 64.

Biology

Zweilous is a dark-blue, quadrupedal Pokémon with two heads and black fur covering its necks and back. Its front legs are muscular with two claws on each foot, but its rear legs are less defined and have two small, backward-pointing toes without claws. There are tufts of fur over its heads with rounded points at the top. It has two thin wings on its back, each ending in two points. The fur stops at the chest and opens up to fuchsia striped bands on the side of its legs. Though it appears to lack eyes, it is unknown if Zweilous is blind.

Zweilous has the vigor and energy to eat and bite constantly without stopping. Its heads dislike each other and are very hostile. Each head has their own likes and dislikes. As a result, the heads often turn eating into a competition, each head trying to claim leadership by eating more than the other. Because of this, Zweilous always eats far too much and is covered in scars, even without opponents to fight. This allows Zweilous to become stronger without any allies helping it. It is a nomadic Pokémon; it migrates once it has eaten all the prey in an area.

Major appearances

Zweilous made its main series debut in A Village Homecoming!, where two of them were owned by Iris's friend Shannon. The older of the two eventually evolved into Hydreigon.

In Aiming for the Top Floor!, Ryuki first used a Zweilous during his battle against Kiawe. It easily defeated Marowak after the latter got distracted by Ryuki's music. Zweilous was then used in a Double Battle alongside Druddigon, going up against Ash's Rowlet and Meltan, but both were soon defeated.

Zweilous debuted in Kyurem VS. The Sword of Justice during the World of Pokémon introduction.

A Trainer's Zweilous appeared in Settling the Scorbunny!.

A Trainer's Zweilous appeared in Secrets of the Jungle.

A Zweilous appeared in Trial on a Golden Scale! under the ownership of one of Nito’s henchmen.

Scarlet The two heads do not get along at all. If you don’t give each head the same amount of attention, they’ll begin fighting out of jealousy.
Violet The two heads have different likes and dislikes. Because the heads fight with each other, Zweilous gets stronger without needing to rely on others.

Trivia

  • Of all the Pokémon that evolve by level alone, Zweilous can evolve into its final form, Hydreigon, starting at the highest level, evolving at level 64.
  • According to interviews with Ken Sugimori in Nintendo Dream, Zweilous and its evolutionary family were originally intended to have aspects of tanks. These 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 Zweilous's underbelly are a remnant of this design.[1]
  • Zweilous shares its category with Red- and Blue-Striped Basculin. They are all known as the Hostile Pokémon.
  • Zweilous and Deino are the only Pokémon who have Hustle as their only Ability.

Origin

Zweilous seems to be based on many-headed antagonistic dragons or serpents in various mythologies, such as the Yamata no Orochi, the Lernaean Hydra, or the Zmei Gorynych; the latter in particular is known to be deceptive, as well as being described as having green scales, which may inspire Zweilous's Shiny coloration. Due to its apparent blindness and only being found in caves, Zweilous may also be based on a cave salamander.

Name origin

Zweilous may be a combination of zwei (German for two) and jealous (as the heads always fight over food) or zealous (reflecting Zweilous's voracious appetite and intensely competitive nature).

Dihead may be a combination of di- (Greek prefix for two) or 二 ji (two) and head.
