Elgyem (Japanese: リグレー Ligray) is a Psychic-type Pokémon that evolves into Beheeyem starting at level 42.


Elgyem is a light blue extraterrestrial Pokémon with an oblong head with depressions on either side. It has black, symmetrical lines going down the front of its head. On the front of its head are shiny, green button-like eyes. Its hands have three finger-like digits: one red, one green, and one yellow. It has short, stubby legs and a small tail. Elgyem controls incredible psychic power, which it uses to squeeze its opponent’s brains, causing them headaches.

Overall, Elgyem has quite the welcoming and informative behavior. It is willing to help in stressful and otherwise difficult situations. However, Elgyem can become fully involved in something it feels to be important and protect that with its life.


  • Elgyem and its evolution Beheeyem are the only species that can have Telepathy without it being their Hidden Ability.
  • Given its science fiction theme, Elgyem evolving at level 42 is likely a reference to that number's significance in the comic science fiction series The Hitchhiker's Guide to the Galaxy.


Elgyem is based on greys, one of the more popular kinds of alien. Its rocky physical appearance may be a reference to the stone circles of Europe, which were allegedly created by visiting extraterrestrials. The colored dots on its hands resembles the colorful faces of the invaders in the 1953 War of the Worlds film; however, the aliens in the film had green, blue and red dots while Elgyem has red, green and yellow. Judging from its Pokédex entry, Elgyem and its evolution may also be based on the Area 51 alien conspiracies or the Roswell incident. Considering its species names, physical appearance, and powers, it may also be based on a brain.

Name originEdit

Elgyem is a corruption of the abbreviation LGM ("little green men"), a common term used to refer to extraterrestrials. Its Japanese name, Ligray, may be derived from greys (a commonly speculated type of extraterrestrial) and may also be a combination of light (as in light-grey) or little and grey (alternative spelling of gray). Alternatively, it may be a combination of little and a corruption of green, referring to the slang for aliens: "little green men."
