Enamorus's tail uncoils, glows pink, and takes the shape of a heart during attacks
In Incarnate Forme, Enamorus is a pink, slim humanoid Pokémon, which resembles a genie. It is a female-only species with no male counterpart. On its forehead are four sharp magenta horns. Enamorus has white hair tied back, with thick strands shaped like a heart on top of its head, white lips, and two pointed pink ears on either side of its head with a small strand of hair falling in front of them from the temples. Its eyes are yellow with beady white irises and no visible pupils. The front of Enamorus's body is covered in magenta spots, most of them shaped like diamonds, pebbles, and magatamas. Its thin chest consists of two joined diamond-shaped pectorals, its shoulders are adorned with magatama shapes, and on top of its navel is a teardrop, all colored magenta. It has two spotted thin arms, with five fingers on each hand. Its lower body consists of a trailing cloud, with a long, brown tail resembling a snake wrapped twice around its neck. Enamorus's tail has magenta heart markings lined in black running its span, with a pair in place at the end of its tail resembling eyes and another resembling a mouth.
Enamorus is known as the Herald of Spring and God of Spring. The reason is that it arrived from the sea into the Hisui region. This usually signals the end of winter and the rise of the spring season. Enamorus tends to reside in the Crimson Mirelands. It stays in Incarnate Forme when staying in a region. Enamorus's love was said to have given rise to fresh life in the Hisui region. Enamorus can unleash up to four mini cyclones and surround itself with a cloud shield to protect itself from harm.
Enamorus has two forms: Incarnate Forme and Therian Forme.
In Therian Forme, Enamorus resembles a flying cloud turtle and snake hybrid Pokémon. The feet are magenta three-toe flippers connected to pink arms with single magenta, magatama-shaped spots on the front legs. The trailing cloud now rings its body, leaving bare its pink belly, with the end having a small cloud tail; its belly has a green gem where its navel should lie. The long, brown snake-like tail is coiled on the cloud body, acting as the top of its shell; the false snake head remains, as do the heart-shaped markings along it. Its pink head now resembles a long-nosed turtle, with a long neck that protrudes directly from the cloud ring. Enamorus retains the four magenta horns on its forehead, but they are stubbier. The tip of its nose is white and heart-shaped, connected to a curved white mustache that extends to both sides of its nose. It retains its yellow eyes with beady white irises and short white hair resembling a hair bun with strands shaped like a heart on top.
Therian Forme Enamorus is known to be vengeful to those who disrespect any form of life. It will descend from the clouds and deliver a wrathful, ruthless punishment in the process. The Therian Forme of Enamorus is believed to be the true form of Enamorus. It is known to travel around oceans in its Therian Form in search of a region to reside in. The Therian Forme of Enamorus was first discovered by the Celestica people who resided in Hisui and worshiped it.
Enamorus has two interchangeable forms: Incarnate Forme and Therian Forme. By default, Enamorus is in its Incarnate Forme. When exposed to the Reveal Glass, it changes into its Therian Forme; if exposed to the Reveal Glass again, it reverts back to its Incarnate Forme. The two forms have different base stats, Abilities, and cries. Its Therian Forme only has one possible Ability, despite its Incarnate Forme also having a Hidden Ability.
Despite being a Flying-type Pokémon, Enamorus cannot learn any Flying-type moves by leveling up.
Enamorus is the only Pokémon introduced in Pokémon Legends: Arceus to not evolve from a previously introduced Pokémon. However, it is a member of a previously introduced group of Legendary Pokémon, the Forces of Nature.
Enamorus is the only Pokémon who can have Cute Charm naturally as an Ability that cannot learn Attract.
In Incarnate Forme, Enamorus may be based on Ugajin, a harvest and fertility kami represented with the body of a snake and the head of a man or woman. Enamorus appears to be based on the female deity, which was syncretized with Benzaiten, a Japanese Buddhist deity who originated from the Hindu goddess Saraswati. In addition, it may be inspired by other snake-bearing goddesses, especially Manasa in Hinduism and Bodhisattva Janguli in Chinese Esoteric Buddhism, who symbolized the triumph over evil snakes or dragons, and were worshipped for the cure of snake venom and patronage of fertility. Its association with spring may also draw inspiration from the ancient Mesopotamian goddess Inanna or Ishtar, who represented the planet Venus and the transition into spring in Babylonian astrology.
Like the other members of the Forces of Nature, it may also have drawn some inspiration from Jinn or an Anemoi. For the latter it may be specifically inspired by the west wind Zephyrus, who is associated with flowers, the springtime, and procreation, which is shown in the Pokémon's ability to bring life and its signature move, Springtide Storm. It also shares similarities with the Mayan depiction of Kukulkan at Yaxchilan. The way Enamorus's snake-like tail is wrapped around its neck may be a reference to constriction, a hunting method used by snakes, or to the feather boa, an accessory worn around the neck.
In Therian Forme, Enamorus may be based on reptiles, namely a softshell turtle and a snake. It may also draw inspiration from the Black Tortoise (Chinese: 玄武 Xuánwǔ) of the Chinese Four Symbols; like Enamorus, the Black Tortoise is usually depicted with a snake wrapped around it. However, despite Enamorus being associated with spring, the Black Tortoise represents winter. Therian Forme Enamorus's Pokédex entry, which mentions it punishing those who disrespect life, may be inspired by stories of turtle eaters being revenged by demonized softshell turtles in Edo-era literary sketches, such as Hokuetsu Kidan and Kaidan Tabi no Akebono. Its form difference could also draw inspiration from the Edo-era superstition that softshell turtles are capable of shapeshifting.
