Solosis is a round, green Pokémon surrounded by a darker green, gel-like substance. This liquid covering allows Solosis to live under any conditions, even in the vacuum of space, but when taking heavy blows, its fluid covering may leak away. Its inner body has dark, oval eyes and a red diamond-shaped mouth. On the upper left side of its head is a curly, yellow growth that resembles the endoplasmic reticulum of a cell. It uses psychic powers to communicate with telepathy, as well as to drive away potential threats.
Pokémon Super Mystery Dungeon: Solosis appears as a friend of a group of Litwick. To create fear for the Litwick to feed on, Solosis creates an illusion of Giratina to scare the citizens of Serene Village. The students of the village school eventually discover the deception, but let the culprits go on the condition that they tone down their scaring and secretly help others too.

Major appearances
Solosis debuted in Where Did You Go, Audino?, under the ownership of Doyle. It was used to help locate some missing Audino. Upon encountering Ash and his friends, Doyle commanded it to use Psychic on them as he thought they were suspects. Later, it helped up by getting the group over a cliff so that they wouldn't lose sight of Audino. Solosis was then used to battle Team Rocket by using Confuse Ray on Woobat and Night Shade on Yamask.
Solosis, the Cell Pokémon. A membrane filled with fluid surrounds Solosis's body which allows it to live anywhere. It defeats its enemies using its formidable Psychic-type powers.
Solosis can be seen as a parallel to Gothita. Both are Generation VPsychic-type Pokémon evolving once at level 32 and then again at level 41. Solosis is exclusive to Pokémon White, White 2, and Shield, while Gothita is exclusive to Pokémon Black, Black 2, and Sword. They both have the same base experience and catch rates, gain new moves at similar levels and have base stat totals of 290.
Solosis and its evolutionary relatives are the only known Pokémon to learn Thunder by TM/TR but not Thunderbolt in every generation they appear in.
Origin
Solosis and the rest of its evolutionary line seem to bear reference to cells, with the head representing the nucleus, the green substance surrounding their bodies resembling cytoplasm and the objects inside their bodies representing organelles. The line down its head also resembles a cleavage furrow in cell biology. It may also make allusion to the embryonary stages, specifically the stage of morula.
Solosis's ability to survive in extreme conditions, including the vacuum of space, may be inspired by extremophiles or other highly resistant micro-animals such as the tardigrade.
Name origin
Solosis may be a combination of solo (singular) and meiosis or mitosis (cell division).
Uniran may be a combination of uni- (prefix meaning one, as in unicellular organism) and 卵 ran (spawn). It may also refer to se unirán (Spanish for "they will join together"), as Solosis appears to be made of two parts.
