Notable Biology

A line of mysterious and shy Pokémon, the very existence of this particular line was covered up for many years. Both Elgyem and Beheeyem are a line of humanoid Pokémon, with enlarged heads and diminutive bodies. Most peculiarly, each member of the species has a peculiar pattern of geometric lines inscribed on their foreheads, in addition to having their bodies, in particular their hands, studded with a variety of small, gem-like protrusions. It is believed that these gems act as conduits for the species to focus and extend their psychic powers, with differently-colored gems helping to amplify and refine certain parts of the creature’s brain. These abilities are frequently used to help lift and manipulate objects; a feature that is quite fortuitous as both members of the line lack physical digits. Such is their telekinetic prowess that the line rarely uses their (heavily atrophied) legs to walk, instead preferring to hover several inches in the air. In terms of competitive battling, both Elgyem and Beheeyem are capable of learning a variety of Psychic-type moves.

Beheeyem are the evolved form, and seem to be the ‘dominant’ member of the species. Elgyem will automatically group around a Beheeyem if one is placed nearby. Exactly why is not sure, but psionic studies of the creature’s brain reveals that it is designed very differently from human brains or even the brains of most Psychic-type Pokémon. As far as researchers can figure out, the brain of a Beeheeyem is comprised of multiple cortexes arranged radially, each lobe having total control over one function of the body. Such a unique brain shape requires a large skull, which explains the large dome-shaped head of the species. Using its psionic powers, it seems to be able to command several Elgyem much in the same way that other eusocial Pokémon like Vespiquen command lesser members of their social group.

The relation of Elgyem and Beheyem to other extraterrestrial species like Deoxys is still a mystery. When a Beeheeyem was shown a picture of Deoxys, it first attempted to communicate with it via systematic flashing of its gems and psionic signals. When this failed, it automatically resorted to a defensive stance and prepared to attack. Exactly what happened between these two species is a question that is perhaps best left undiscovered.

Owing to their unique history and behaviour, it is no small wonder that the line has gained quite popularity among both Pokémon trainers and the general public. The line has served as the inspiration for several popular film and television characters, such as a villainous Beeheeyem intent on vaporizing a wisecracking Chillarmy or the popular cartoon series about a megalomananical Elgyem who attempts to take over the world with the aid of a malfunctioning robot.


The Elgyem line had never been seen in the Unova region, or indeed on this world, until June-July 1947. During that particular summer, there had been an unusual number of meteor showers and odd magnetic fields, causing an effect not dissimilar to the aurora borealis commonly seen at the north and south poles. What was most startling, however, was that one particular ‘shooting star’ resulted in a scattering of bizarre metallic debris in the Desert Resort region. Emergency workers and government agents were quickly dispatched, and, while no bodies, human or otherwise, were recovered from the crash, several dozen footprints were seen leading away from the site and out into the desert. It is unknown exactly how many Elgyem and Beheeyem were introduced to our world that day, but what can be known is that the species’ numbers have swelled since making planetfall. Perhaps owing to the disproportionate number of Dark and Ghost-type Pokémon in the area, the species migrated northwards and now lives in scrublands and some abandoned man-made settlements. The largest recorded group dwells in the Celestial Tower along Route 7, but some have also been seen in abandoned buildings or secluded areas. Occasionally, Elgyem or Beheeyem may inadvertently come into contact with humans. The first such incident took place not long after their arrival to the world. A young farmer and his family were reportedly ‘terrorized’ by the creatures, who continually hovered around the windows but did little else. Gunshots did not seem to do much except frighten them and cause them to backflip in the air with a loud metallic noise, and the creatures remained around the house until the morning.

The original homeworld of the line, has, to date, remained unknown. From observations recorded by Pokmeon biologists and professors, Elgyem and Beheeyem sometimes seem to send psionic signals in the direction of certain stars. One star that seems to be the largest focus of their attention is Polaris, the North Star. Many biologists have theorized that their homeworld orbits this star, although this has yet to be proven.


Both members of the line have never been observed to eat anything in the wild. While they have functioning digestive systems, it is believed that they may metabolize an unknown form of energy for food. However, at periods Elgyem and Beheeyem will conduct extraordinarily coordinated raids on farmsteads in which they will abduct one or more Miltank for reasons unkown. These ‘abductees’ rarely turn up again, and those that do seem remarkably shaken.


Despite their frail bodies and comical proportions, the Elgyem line, Beheeyem in particular, are extremely powerful telepaths, seconded only by legendary creatures such as Mewtwo. Lacking any real physical defence mechanisms, an Elgyem’s power is purely mental. Psionic attacks, ranging from ear-splitting headaches to total incapacitation of nerve centres will be unleashed should an Elgyem’s life be in danger. However, far more common and insidious is their ability to erase and rewrite memories. It is unknown exactly how this works, but, when threatened, the psychic energies released by the line seem to automatically target those areas of the brain related to information storage and transference, most often the brain areas related to short-term memory. Depending on the level and age of the creature, this power will vary. Usually, victims will only forget short stretches of time; although they can easily remember said ‘missing time’ when put under hypnosis. However, some victims have been known to forget their name or age. Several unfortunate victims have had their entire memories erased and rewritten, leaving them little more than very confused and disoriented individuals. It has been hypothesized that many more people than initially believed may have caught these Pokémon, only to lose all memories of them when the errant Pokémon decided it had had enough of being trained and broke free, pausing only to make its Trainer conveniently ‘forget’ its existence.

Courting and Childrearing

Elgyem and Beeheeyem have never been observed mating. Small, fully-formed Elgyem have been observed but mating rituals between Beheeyem are still a mystery.

Social Structure

Elgyem and Beeheyem, in the wild, live in tightly knit groups, with one Beheeyem presiding over several dozen Elgyem. Each group is very rigidly organized. What has intrigued researchers is that each group seemed to be organized after one of the prime numbers, with groups of 2, 3, 5, 7, or 9 Elgyem being the most common. At intervals, the groups will also emanate very strong telepathic signals into space, as if broadcasting a locating beacon or summoning something. Exactly what they are trying to locate or summon is still a manner of heated debate.

Elgyem and Beeheeyem communicate among one another through systematic flashing of their gems. Some scientists are currently attempting to understand the meaning of these messages, but as of right now the project has not been fruitful. Attempts to use other Psychic-type Pokémon to communicate with the species has been similarily useless, the Pokemon either being unable to understand them or, in one case, truly and utterly terrified by what they saw in the creature’s mind. The Musharna that was responsible for the latter experiment has refused all food and drink, and seems to be fixated on one particular star in the sky. Why this is so, like so many other aspects of the creatures, has remained a mystery.
