Hydreigon

() is a /-type Pseudo-Legendary Pokémon introduced in Generation V.
==Biology==
===Physiology===
Hydreigon is a large three-headed draconic Pokémon. It is mainly blue with scruffy black fur covering its arms and neck. The black fur that covered up its eyes as a Deino and Zweilous has disappeared, creating a frill-like appearance and is now magenta in color. Instead of having one wing-like appendage on each side of its body, it now has three wings on each side of its body that allow it to fly. On the end of each arm is a smaller blue head with eyes and a mouth, but no brain. Hydreigon uses both its main head and its head-like hands to voraciously devour its food. After Zweilous evolved, its tail has grown longer and has magenta scales on the underside as well as a black tip on the end. Its round, plump belly has two rows of magenta scales just like it had when it was a Zweilous. Its abdomen seems to have grown plumper and fuller as a result of eating so much food as a Zweilous.
Hydreigon has relatives in the future, known as Iron Jugulis.
===Behavior===
Hydreigon is said to be a violent and brutal Pokémon that devours and destroys everything it sees. However, it appears to be harmless and loyal when raised and owned by a skilled trainer. As seen in the anime, it will allow its trainer to ride upon its back and fly. 
In Pokémon Mystery Dungeon: Gates to Infinity Hydreigon is a wise and very kind Pokémon who represents and embodies the Voice of Life; he is endearingly quirky and will assist the hero throughout the game. 
The two smaller "heads" lack any form of free will as the main head is usually intelligent and has a brain; despite this, Hydreigon usually thinks of destruction. Many people despised Hydreigon in the past, which caused it to become more ferocious. 
==Evolution==
Hydreigon is the final form of Deino, and evolves from Zweilous at level 64.

==Trivia==
*Before its introduction, Pseudo-Legendary Pokémon traditionally had Attack as their highest stat (usually from 130 to 135). Hydreigon breaks this trend, by having a higher Special Attack than Attack (125 compared to "only" 105).
**It is the first Pseudo-Legendary Pokémon whose highest stat is less than 130, but the only one whose lowest stat(s) are no lower than 90.
*Hydreigon evolves at a later level than any other Pokémon, at Level 64.
**Of all the evolved Pokémon that require a specific level, Hydreigon is the only one that has more than one-quarter of its Level 100 EXP requirement to reach its evolution level. At Level 64, it has 327,680 experience points, roughly 26.2% of the 1,250,000 needed to reach Level 100.
*Hydreigon and Metagross are the only Pseudo Legendaries that have 2 stats above 100; in this case, it's Attack and Special Attack. Most pseudo legendaries have 3 stats above one hundred. Tyranitar and Kommo-o have 4 stats above 100.
*The frills around Hydreigon's heads were covering its eyes in its previous forms. It is possible that its "hands" were originally Zweilous's two heads.
*Ghetsis' Hydreigon is under-leveled, being at Level 54 despite Zweilous not evolving until Level 64.
*Hydreigon is one of the hardest to obtain due to the high level it evolves at, beating even Dragonite and Tyranitar, and because Deino, its first form, can only be obtained in Victory Road and does not appear very often.
**However it has become relatively easier to obtain since Pokémon Black 2 and White 2 now feature Zweilous in Victory Road though it also does not appear very often.
*The Pokédex says that the heads on Hydreigon's arms lack brains, but it still uses them to eat and destroy things like hands since they're probably connected to the main head's brain and may possess "pseudo-brains" similar to the tentacles of an octopus. Their eyes and mouths may also be connected to Hydreigon's main brain, allowing it to sense its surroundings at three separate ways.
*Hydreigon also somewhat resembles Giratina in origin form, given that both Pokémon have six tentacle-like wings.
*Hydreigon is the only Pokémon to have heads for hands, though Scizor's Pokédex entry in Gold and HeartGold say its pincers resemble heads.
**Hydreigon is one of five Pokémon to have three heads, the others being Combee, Dugtrio, Dodrio and Exeggutor.
*Hydreigon can learn at least one move of each type except -type and -type moves.
*The patterns on Hydreigon's sides bear resemblance to tank treads used in wars.
*It shares its species name with Sharpedo, both being known as the Brutal Pokémon.
*Hydreigon is one of the collectable spirits in Super Smash Bros. Ultimate.
*Hydreigon and its evolution line are the first Dark and Dragon types, the second being Guzzlord.
===Origin===
Hydreigon is based on a multi-headed dragon, possibly the Hydra or Yamata no Orochi from Greek and Japanese mythology, respectively, due to it gaining heads through its evolutionary line. It could have been inspired by , a kaiju, which is Godzilla's nemesis. It may also be based on polycephaly, an occurrence that causes an organism to be born with two or more heads.
===Etymology===
Hydreigon comes from hydra, drei (German for "three"), and dragon.
