Entei

Entei (エンテイ Entei) is a Fire-type legendary Pokémon. Entei is part of the legendary beasts trio from the Generation II games.

Special Abilities
It has the Pressure ability.

Pokedex Entry: It is said that when it  roars , a volcano erupts somewhere around the globe. Sources:

Like Raikou, it likes to course headlong across the land in a display of its raw power; but instead of dishing out lightnings, it spouts flames that are hotter than magma. It also sends up massive bursts of fire that utterly consume all that they touch.

'Fake' Entei
Some Pokedex entries state an Entei is born each time a volcano appears. But since Entei is legendary, it must be unique. These volcano-created Entei are therefore 'fake' Entei, and the only 'real' Entei is the one born at Brass Tower.

Trivia

 * The collective term of Legendary Beasts continues to be the only CANON and sensical term to describe the trio, as they all have different traits regarding cats, dogs, and other animals. The popular term of "dogs" or "cats" were initiated in unofficial Gold and Silver Guidebooks respectively, and the dubbing company 4kids also made this conclusion; however neither term is truly correct when really taking a look at the origins of the trio.


 * The common debate of the legendary beasts' origins is skewed in the belief they all either follow the role of being cats or dogs; however the legitimate origins of these beasts is truly a mixture of both creatures along with mystical beings as well. Entei is partially inspired by lions, but also shares a strong resemblance with the Fu Dogs of Chinese lore or even the Shisa of Okinawa legend (Both of which are lion-dog creatures of Asian folklore). He also appears to have a mane and a short muzzle that are resembling of lions or flat-faced dogs. Entei also exhibits many lion like poses in his movie and has been known to roar as such. http://i49.tinypic.com/28bxngn.jpg


 * It is believed that Entei, before it perished in the Burnt Tower, was a Flareon. This is supported by the fact that the Burnt Tower is in Ekruteak City, a city where Eevee and it's evolution forms are very popular.
