Furthermore, Solgaleo and Lunala evolve from Cosmoem and can create Ultra Wormholes. With the power of both Pokémon, they can create Cosmog. When grouped with their pre-evolutions, they are also referred to as the Cosmog line. Necrozma can create Ultra Wormholes as well. The trio is well known for having brought light into Alola when it was born and the creation of Z-Moves.
Solgaleo and Lunala were introduced as the mascots in the first Generation VII core games, Pokémon Sun and Moon, and two forms of Necrozma were the mascots for the second Generation VII core games. Solgaleo is an emissary of the sun known as the "beast that devours the sun". Lunala is an emissary of the moon known as the "beast that calls the moon". According to Pokédex entries, Solgaleo and Lunala are said to be, respectively, the male and female evolutions of Cosmog. However, the gender of both are actually considered unknown by the games. Necrozma, the third member of the trio, actively seeks out the other two in order to steal the light they possess, which will allow it to regain its true form, Ultra Necrozma. When Necrozma steals the light of Solgaleo or Lunala, it becomes Dusk Mane Necrozma or Dawn Wings Necrozma, respectively, which, through the Ultranecrozium Z and the Ultra Burst transformation, can become Ultra Necrozma.
The mythologies of the trio talk about their connection to the ancient Alola royal family and the civil war between islands that happened in the region long ago. According to a book called "The Light of Alola" found in Malie Library, a SolgaleoSUS/LunalaMUM appeared in Alola many years ago through an Ultra Wormhole. The ancient kings of Alola bowed down to the Legendary Pokémon, worshiping it. The legendary Pokémon created a guardian to bring peace to each island: the Guardian deities. After achieving peace in the region, the Guardian deities battled the legendary Pokémon, but were defeated by it, who then however gave the Tapunium Z to them as a reward. The Legendary Pokémon then created several Cosmog as heirs for Alola, giving the Guardian deities the task of watching over them until they have fully evolved.
The kings of Alola gave their thanks manufacturing two flutes, the Sun and Moon Flutes and in gratitude, they played a song on the at the Altar of the SunneSUS/Altar of the MooneMUM, at which point the Legendary Pokémon returned to Ultra Space. It is said that if the melody of the flutes is played again at a truly necessary moment, the legendary Pokémon will return.
In ancient times, Necrozma was referred to as the "Blinding One" who once shared its light across Ultra Space and Alola. Z-Moves were created from this light along with the aura that surrounds Totem Pokémon. However, the residents of Ultra Megalopolis attempted to gain control of Necrozma in order to recreate the light it shares. As a result, Necrozma was permanently crippled, transforming into a crystalline body while experiencing constant pain. Pieces of its original body rained down onto Alola in the form of Sparkling Stones, which would result in the creation of the Z-Power Ring. Necrozma attempted to return to its original form by stealing all of the light from Ultra Megalopolis, leaving it covered in darkness. In response, the residents locked Necrozma in the Megalo Tower in order to prevent it from escaping.
According to secret notes found in the Malie Library, Necrozma at one point invaded Alola, stealing all of its light, covering the region in darkness as a result. SolgaleoUS/LunalaUM, along with the Guardian deities, fought together against Necrozma at the Tapu Village to recover the stolen light. Necrozma then defeated and absorbed the Legendary Pokémon to become Dusk ManeUS/Dawn WingsUM Necrozma. A youth, along with the Guardian deities, used the power of the Z-Crystals and Sparkling Stones to free SolgaleoUS/LunalaUM from Necrozma, who was then banished from Alola. At as a result of its actions, Necrozma was called the "Pillager of Light" by the ancient king of Alola, who ordered that all books mentioning Necrozma were to be burned to prevent further panic. However, not all were destroyed.

In Pokémon Sun and Moon, Lillie takes care of a Cosmog named Nebby, which she fled from Aether Paradise with in order to save it from the Aether Foundation's experiments. Lillie keeps Nebby in a bag as an attempt to both keep it safe and to keep it from sight. Lillie and Nebby are eventually kidnapped by the Aether Foundation, and Lusamine takes Nebby and uses it to open Ultra Wormholes. Nebby then evolves into Cosmoem. Later, when the player and Lillie play the Sun and Moon Flutes at Altar of the SunneS/Altar of the MooneM, Nebby evolves into SolgaleoS or LunalaM, which is then caught by the player.
Necrozma will first be battled as either Dusk Mane NecrozmaUSor Dawn Wings NecrozmaUM at Altar of the SunneUS/Altar of the MooneUM, and again as Ultra Necrozma at Megalo Tower. In both encounters, it cannot be caught. Necrozma can be caught afterwards at Mount Lanakila.

Pokémon Evolutions
In The Eclipse, Selene and Lillie approach the Altar of the Moone and together, they play the Sun and Moon Flutes to activate the altar. A bright pulse of light erupts from the altar's central platform, prompting Nebby to fly into the light, evolvingCosmoem into Lunala as the light fades. A Ultra Wormhole opens up above the altar, dropping Lusamine and Guzma to the ground, severely beaten and injured. Lillie runs over to her mother, and a clearly shaken Lusamine begs for the children to run away, describing the legendary Pokémon Necrozma as a monster that attacked as soon as it was approached.
Later, Necrozma tears its way out of the wormhole, and after exchanging a look with Lillie, Lunala soars forth to do battle, exchanging series of devastating attacks with the Prism Pokémon. Ultimately, after Nebby gets pinned by Necrozma, the latter absorbs Nebby into its body, changing into its Dawn Wings form.
It was revealed that Cosmog had evolved into a Cosmoem and was picked up by Plumeria. Plumeria tried using it to force Faba to tell her where Guzma was taken to. Before she could get her answers, it flew out of her hands and met with Nebby in the skies above Poni Island. Upon Play the Melody That Echoes in the Altar, the guardian deities took Sun and Moon and placed them on the Poni Altar with the Sun and Moon Flutes. By playing the flutes together, Sun and Moon caused the Altar to react and release a light that hit both Cosmoem. The light caused Cosmoem and Nebby to evolve into Solgaleo and Lunala, respectively.
