Generation V · #0605 — Cerebral Pokémon
Elgyem, known as the Cerebral Pokémon, is a Psychic-type creature that first appeared in Generation V, standing as Pokédex entry #605. This diminutive extraterrestrial Pokémon measures only 0.5 meters in height and weighs a mere 9.0 kilograms, making it one of the smallest psychic-type Pokémon in the National Pokédex. Despite its unassuming stature, Elgyem possesses formidable psychic abilities that belie its fragile appearance. The Pokédex entries across multiple generations consistently link Elgyem's mysterious origins to a UFO crash site in the desert that occurred approximately 50 years before the events of the games, suggesting an extraterrestrial heritage that sets it apart from most terrestrial Pokémon species.

Elgyem's physical form is distinctly alien in appearance, featuring a cyan-colored body with an elongated, oblong head characterized by pronounced depressions on either side. Two symmetrical black lines run vertically down the front of its head, framing a pair of luminous green button-like eyes that radiate an otherworldly intelligence. The Pokémon's most distinctive feature is its hands, each bearing three digit-like appendages colored red, green, and yellow respectively, giving it a peculiar, almost mechanical appearance that reinforces its extraterrestrial nature. It possesses short, stubby legs that appear inadequate for rapid terrestrial locomotion, and a small tail that extends from its lower body. With a base stat total of 335 and a Special Attack stat of 85, Elgyem's biological composition is clearly optimized for psychic manipulation rather than physical combat, reflecting its cerebral designation.
Elgyem maintains a balanced gender ratio of 50% male and 50% female, making it equally viable for breeding purposes regardless of trainer preference. The species belongs to the Human-Like egg group, allowing it to breed with a diverse range of Pokémon that share this classification, including other psychic-types and humanoid creatures. Eggs produced by Elgyem require 20 cycles to hatch, translating to approximately 4,884 to 5,140 steps of travel before the offspring emerges. The base friendship value of 70 indicates that newly captured Elgyem will begin with moderate affection toward their trainers, providing a positive foundation for bonding and obedience. The medium-fast experience growth rate means that Elgyem reaches level 42 evolution in a reasonable timeframe, neither requiring extensive grinding nor advancing so rapidly that trainers feel rushed.

Elgyem undergoes a straightforward evolutionary progression at level 42, transforming into Beheeyem, a more developed Psychic-type that builds upon its base form's cerebral prowess. The evolution represents a maturation of Elgyem's psychic abilities rather than a dramatic morphological transformation, with Beheeyem maintaining the same type classification while gaining increased base stats across the board, particularly in Special Attack and Speed. This single-stage evolution chain follows the medium growth rate pattern, allowing trainers to cultivate Elgyem from its early acquisition through a reasonable developmental period before achieving its final form. No Mega Evolution exists for either form of this line, nor are there any alternate forms or regional variants that modify Elgyem's appearance or capabilities.

Elgyem exhibits surprisingly welcoming and cooperative behavior despite its alien origin, demonstrating a willingness to assist other creatures in stressful situations and difficult circumstances. However, this generally amiable demeanor transforms dramatically when the Pokémon becomes invested in something it deems important, at which point it will defend that interest with unwavering dedication and protective fervor. The species' most remarkable behavioral trait manifests when Elgyem stands in proximity to television sets: strange and otherworldly scenery begins appearing on the screens, which is widely believed to represent images from Elgyem's actual home dimension. This phenomenon suggests that Elgyem maintains a profound connection to its extraterrestrial origins despite dwelling on Earth, and may serve as a visual window into its mysterious past. The Pokémon's primary habitat appears to be desert regions, particularly those associated with the legendary UFO crash site mentioned in various Pokédex entries.

The name Elgyem derives from the Japanese name Ligray, which itself appears to be a fusion of linguistic elements referencing its cerebral nature and alien origins. The English designation 'Elgyem' may be interpreted as combining 'El' (Spanish for 'the,' suggesting cosmic nomenclature) with 'gym' (referencing the Latin-derived suffix relating to knowledge and mentality). The design philosophy emphasizes an extraterrestrial aesthetic, with the three-fingered hands colored in primary colors evoking computer or alien technology imagery popular in science fiction. The cyan coloration and button-like eyes create an uncanny valley effect that positions Elgyem as distinctly non-terrestrial, while its small stature and prominent head-to-body ratio emphasize intelligence over physicality. The symmetrical black lines on its face evoke technological patterns or data streams, further reinforcing the impression of a being from an advanced alien civilization.

In competitive Pokémon battles, Elgyem occupies a niche as a early-game or in-game special attacker, though it sees limited use in serious competitive formats due to its modest base Special Attack of 85 and notably poor Speed stat of 30. Its ability to learn Confusion at level 1 and progress to Psybeam at level 18 provides reliable psychic coverage for common threats, while Teleport offers utility for repositioning or escape. The ability Analytic, Elgyem's hidden ability, becomes relevant when the Pokémon moves last in a turn, boosting its move power to 1.3 times, which synergizes with its low Speed stat by guaranteeing it will function optimally when using priority-disadvantaged strategies. Synchronize and Telepathy serve as alternative abilities with situational value in double or triple battles, where Telepathy prevents friendly Pokémon from being hit by damaging moves. Competitive trainers typically evolve Elgyem to Beheeyem as quickly as possible, as the evolution provides the stat boosts necessary to remain viable in the middle stages of gameplay.

Elgyem represents Generation V's exploration of science fiction themes within the Pokémon franchise, introducing an explicitly extraterrestrial species whose mysterious origins intrigue players and inspire speculation about the broader Pokémon universe. The species has achieved notable recognition within the fan community as a beloved example of genuine alien-inspired design, contrasting with more humanoid psychic-types and earning appreciation for its distinctly otherworldly aesthetic. The UFO crash site lore connected to Elgyem's origin has generated fan theories and discussions about potential connections to other mysterious Pokémon and locations throughout the series. Its appearance in the anime and various spin-off media has solidified its place in Generation V's roster of memorable creatures, though it remains somewhat underutilized in mainstream competitive contexts. The Pokémon's unique design philosophy of prioritizing extraterrestrial alienness over kawaii appeal or conventional cuteness has earned it a dedicated following among players who appreciate its unconventional visual presentation.
Elgyem's availability has evolved throughout the Pokémon generations, with its first appearance occurring in Generation V's Unova region, where it received Pokédex entry #111 in Black and White. In the subsequent Generation V games Black 2 and White 2, Elgyem's Pokédex number shifted to #188 within the expanded Unova dex. The species maintained presence throughout Generations VI and VII, appearing in various Alola-region encounters with Pokédex number #275 in Ultra Sun and Ultra Moon. In more recent generations, Elgyem received inclusion in Sword and Shield's Galar Pokédex at entry #277, confirming its continued viability in modern competitive and casual play. The creature's excellent catch rate of 255 means that trainers can reliably capture it without requiring specialty Poké Balls or weakening tactics, making Elgyem readily accessible to players seeking a psychic-type companion early in their journey through the respective regions where it appears.
