Cosmoem (Pokémon)

This article is about the species. For a specific instance of this species, see Cosmoem.

**Cosmoem** (Japanese: **コスモウム** *Cosmovum*) is a Celestial-type Legendary Pokémon introduced in Generation VII.

It evolves from Cosmog starting at level 43 and evolves into either Solgaleo or Lunala starting at level 53 depending on the game it evolves in.

* In Pokémon Sun, Ultra Sun, and Sword, Cosmoem evolves into Solgaleo.
* In Pokémon Moon, Ultra Moon, and Shield, Cosmoem evolves into Lunala.

## Biology

Cosmoem is a Pokémon in the shape of a translucent, dark-blue orb with a starscape pattern set in a golden shell-like structure. The main portion of the shell is a flat oval around the center of the orb. Eight more flat, half-oval projections surround the orb in an asterisk-shape. At the center of the main body is a much smaller black core. The upper half of the core has a thin blue line on the front, back, and each side, while the lower has pink lines. On the front are two orange semicircles, which appear to be closed eyes. The overall shape of this Pokémon also resembles an eye.

Encased in its sturdy, cocoon-like shell, Cosmoem is unable to move. In Pokémon Refresh, it cannot even eat. It grows as it absorbs starlight and the dust in the air. Its body is warm to the touch. Cosmoem's shell is said to be harder than any known material. In ancient times, it was worshipped as the "cocoon of the stars" by the people of Alola.

Cosmoem is one of the shortest Pokémon in existence. Despite this, it is also the heaviest Pokémon in existence, being tied with Celesteela.

### Origin

Cosmoem has characteristics of both a stylized sun and a stylized moon, having rays and a pair of crescents, respectively. Its enormous weight despite its extremely small size shares similarities with super-compressed astronomical bodies such as black holes and neutron stars. Given its description, it seems to be an embodiment of star formation in general. It may also be based on the idea of the world egg. When viewed from the front, its shape resembles an eye.

#### Name origin

Cosmoem may be a combination of *cosmo*, *ovum*, and *embryo*.

Cosmovum may be a combination of *cosmo* and *ovum* (Latin for egg).
