Nebby (Japanese: ほしぐもちゃんHoshigumo-chan) is a character introduced in Pokémon Sun and Moon. Although it seems to possess a mysterious power, being a Cosmog, Nebby is depicted as frail and unable to use moves for large parts of the games' storyline. Nebby's name has been given to it by Lillie, who cares for it and tries to find out about its true nature. In an attempt to save it from harm, Lillie often keeps Nebby in her bag in order to hide it from outsiders.
During the opening cutscene, three months prior to the beginning of the player's adventure, when Lillie tries to flee Aether Paradise, she is teleported away by a mysterious force; that force is later revealed to stem from Nebby, who hid in her bag. Lillie and Nebby wash up on a beach, where they are found by Professor Burnet, who agrees to help Lillie learn more about Nebby. She then contacts her husband, Professor Kukui, who allows them to stay with him for the time being.
The player first meets Nebby on the Mahalo Trail, being informed by Lillie that it is being attacked by a group of wildSpearow on an unstable rope bridge. When the player steps in to protect it, Nebby is forced to use its hidden powers, thereby destroying the bridge. It is saved by Tapu Koko while falling. When asking Nebby to return into her bag, Lillie also asks the player to not tell anybody about Nebby. At the Iki Town festival, Nebby watches the player receive their starter Pokémon, and later their Z-Ring. Nebby is with Lillie when she introduces Kukui's lab, the Pokémon Center on Route 1, the Trainers' School, and Hau'oli City to the player.
When the player arrives at Melemele Meadow, Nebby has escaped from Lillie's bag. However, the player can find it unharmed; Lillie then asks Nebby to return to her bag. After the player has completed Hala's trial, Nebby and Lillie accompany the player and Professor Kukui to Akala Island.
At Akala Island, Lillie believes Nebby might be interested in visiting the Ruins of Life. Nebby is next seen at Dimensional Research Lab, where it fails to adhere to Lillie who instructs it to use Splash, and curiously approaches the player. Later, at the Ruins of Life, Olivia suggests that Nebby must be powerful when it approaches Tapu Lele's territory.
In order to make Nebby feel better after the events at Aether Paradise, Lillie travels to Poni Island. Although at the Ruins of Hope, her hopes of Tapu Fini helping Nebby do not come true, she is given the Moon FluteS or Sun FluteM. At the Altar of the SunneS or Altar of the MooneM, Lillie and the player play the Sun Flute and the Moon Flute together during the daytimeS or nighttimeM, and Nebby is drawn from her bag, evolving into SolgaleoS or LunalaM. Upon Lillie's request, Nebby guides her and the player into Ultra Space. In Ultra Space, Nebby roars at Lusamine who has merged with Nihilego, forcing the two apart. Afterwards, Lillie informs the player that Nebby wants to keep on traveling with her and the player; however, Lillie stresses that she is not a Trainer and urges Nebby to join the player. A battle is initiated, and the player is then required to catch Nebby (and in the process, they can give it any nickname).
Nebby plays largely the same role in Pokémon Ultra Sun and Ultra Moon until it evolves into SolgaleoUS or LunalaUM, where it briefly does battle with Necrozma and loses. This allows Necrozma to absorb Nebby and turn into Dusk ManeUS/Dawn WingsUM Necrozma and attack the player. After defeating Ultra Necrozma at Megalo Tower, Nebby is freed from Necrozma and returns to the Altar of the SunneUS/Altar of the MooneUM. After thanking the player, Lusamine and Lillie take Nebby to Aether Paradise to be treated.
After the player defeats Ilima during Mina's trial, they have the option of returning to the now-repaired Mahalo Trail Plank Bridge, where Lillie will ask the player to take Nebby in their care.
In Faba's Revenge!, it was lured out of Ash's bag by Faba, who convinced it to teleport him back to Aether Foundation's sealed lab. After arriving, Faba captured it in a device designed to keep it from teleporting. Faba intended to use Nebby's power to open an Ultra Wormhole, but he was stopped by Ash's Pikachu and Gladion's Umbreon. However, after being released, Nebby evolved into Cosmoem, and the residual energy from the evolution caused a Wormhole to appear anyway.
Nebby was brought to the Altar of the Sunne by Ash in Family Determination!. In the next episode, Ash gave Nebby to the Tapu, asking for their help. After being blessed by Tapu Lele and Tapu Fini, the four deities sung at the Altar, opening the mechanism within and causing Nebby to evolve into Solgaleo, much to the surprise of everyone present. After greeting the others warmly, Nebby accepted Ash, Lillie, and Gladion's plea to help Lusamine, giving Ash a Solganium Z. After having his Z-Ring upgraded to a Z-Power Ring by the Tapu, Ash and the others climbed on Nebby's back, and using the power of the Z-MoveSearing Sunraze Smash, created an Ultra Wormhole to travel to the place Lusamine awaited them.
After arriving in the Ultra Deep Sea in Rescuing the Unwilling!, Nebby and Ash cornered Lusamine during the following episode. As a result, Lusamine flooded their island with a poisonous liquid. Due to Nebby's Steel-type giving it immunity to poison, it protected Ash from the liquid, and then carried him across it, dodging Lusamine's attacks along the way. After that, it went back with Ash's Lycanroc to help the others fight off Lusamine's Pokémon, who continued to heal themselves due to the Nihilego's energy. Everyone later succeeded after Lusamine was freed from Nihilego's control by Ash. Nebby then carried the group, now joined by the revived Lusamine, back to the Altar of the Sunne. After the conclusion of the episode, it parted from the group.
In Full Moon and Many Arms!, Nebby arrived in Alola, where it met up with Ash again and fought Dawn Wings Necrozma in an effort to free Lunala from its control. With its Sunsteel Strike, Nebby managed to knock Necrozma off of Lunala, causing it to break apart and fall into the sea. Shortly after, the elite Team Rocket unit, the Matori Matrix, attacked Nebby and Lunala by trapping them in an electrified net. After being freed by Ash's Pikachu and Gladion's Silvally, Nebby retaliated by attacking the unit's aircraft, forcing them to retreat. Immediately after, Necrozma emerged from the sea and possessed Nebby, causing it become Dusk Mane Necrozma. Ash tried to free Nebby, but was unable to stop Necrozma, and it fled into an Ultra Wormhole.
In The Prism Between Light and Darkness!, Nebby remained fused with Necrozma. The Ultra Guardians, with Lunala's help, pursued Necrozma to the home world of Ash's Poipole, and learned that Necrozma was preying on the two Legendary Pokémon in order to absorb their light and restore itself to its Ultra form. After being asked by Nagandel to save Necrozma, Ash, Kiawe, Lana, and Gladion attempted to use their Z-Moves to supply Necrozma with Ultra Aura and separate it from Nebby. However, they were only successful in making it more powerful. Communication between the Guardians and their home base was soon reestablished. After Lusamine, Wicke, and Professor Burnet shared what they knew, they arranged for the people and Pokémon attending the Manalo Festival to follow the lead of the guardian deities and share a portion of their Ultra Aura with Necrozma. Combined with the Ultra Aura of the Ultra Guardians and their Pokémon, Necrozma received enough light to separate from Nebby. Nebby then joined forces with Ash, Gladion, and Lunala, giving Necrozma one last boost of power with the combined Ultra Aura of their special Z-Moves, Searing Sunraze Smash and Menacing Moonraze Maelstrom. Through these efforts, Necrozma's strength was finally restored. After Ash and Pikachu bade farewell to Poipole, Nebby and Lunala led the Ultra Guardians back to Alola.
Personality and characteristics
In the original Japanese version of the anime, Nebby's official nickname is simply ほしぐもHoshigumo, as opposed to Hoshigumo-chan. The -chanhonorific is still used occasionally, with "Little Nebby" being used instead of Hoshigumo-chan in the English dub. In Now You See Them, Now You Don't!, Team Rocket caught sight of the unidentified Pokémon while Ash was buying donuts from their food truck. James surmised that the unknown Pokémon was the pre-evolved form of Koffing, and named it Protokoffing (Japanse プチドガースPuchidogars). This lead to confusion when the trio saw Cosmoem in Revealing the Stuff of Legend!, causing James to assume that there was an intermediary phase it evolves into in Alola, which he dubbed Nanokoffing (Japanese カタドガースKatadogas), but this was ultimately debunked when they witnessed "Nanokoffing" evolve into the Legendary Solgaleo. After its final evolution, Ash and his classmates typically refer to it by its proper name, Solgaleo.
As a Cosmog, Nebby shared many traits with human babies. It slept and cried a lot, but was easy to amuse and was naturally curious. Its cries were quite powerful, and they caused nearby people and Pokémon to cover their ears. In A Masked Warning!, its cries were so powerful, it sent Pikachu flying back into a tree. Nebby was a very fussy eater and appears to have a preference for the Star candy (Japanese コンペイトkonpeitō). It was also ticklish and enjoys playing hide-and-seek, as shown respectively in A Dream Encounter! and Night of a Thousand Poses!.
In Now You See Them, Now You Don't!, it was shown that Nebby tends to teleport people to places they are thinking or talking about. Rotom surmises this is because it knew little about the world around it, so it had to depend on telepathy and other people to develop its abilities. By the end of the episode, it had become attached enough to Ash, to the point where it would willingly teleport to him on its own whenever they are separated.
After evolving into Cosmoem, Nebby hardly spoke, moved, or emoted, reflective of its coccoon-like state. However, after evolving into Solgaleo, it appeared to have grown into a more mature version of itself physically and mentally, letting Lillie hug it, happily accepting the Star candy from Ash, and licking him affectionately. As a Solgaleo, Nebby can create Ultra Wormholes at will with the help of a Trainer with a Z-Power Ring, a Solganium Z, and its Z-Move, Searing Sunraze Smash.
Description: Solgaleo's Trainer turns the Solganium Z in their Z-Power Ring clockwise and strikes a series of synchronized poses to build Z-Power. Solgaleo then changes to its Radiant Sun phase and opens an Ultra Wormhole and carries its riders through it. Or, without anyone riding it, Solgaleo jumps into the air, cloaks itself with orange-yellow energy, spins itself around, and slams into the opponent with full force.
Nebby first appeared in The Decision and the Tournament of Six, where it escaped from Lillie's bag and ran off to Mahalo Trail, where it was attacked by a group of wild Spearow. Lillie was too scared to help it, so Moon stepped in to save Nebby in her place. When she got to Nebby, it retaliated against the Spearow by releasing a shockwave, causing the bridge they were standing on to break apart underneath them. Moon and Nebby were rescued from falling in the water by Tapu Koko, who caught the two and brought them back to safe land.
In PASM14, Professor Burnet accidentally caused Lillie to recall painful memories of a traumatic experience caused by her mother, Lusamine. Lillie's distress caused Nebby to fly out of her bag and begin clawing at the sky, nearly creating an Ultra Wormhole. After Lillie fainted, Nebby stopped and went down to check on her out of concern.
In PASM17, after Sun completed his second trial at the Thrifty Megamart, he thanked the Rotom Pokédex for its help in the battle where it gave information about Tapu Bulu. To Sun and Lillie's surprised, Rotom revealed it learned about Tapu Bulu from Nebby. Hoping that Rotom could translate Nebby's speech and speed up his job to deliver Mirage Berries to each of Alola's guardian deities, Sun tried to get Nebby to come out. To their shock, Nebby emerged from Lillie's bag in the form of the motionless, cocoon-like Cosmoem.
Later, after arriving on Poni Island, Lillie and Gladion took Nebby with them as they traveled to the Poni Altar. A Xurkitree attacked the duo as they passed through Poni Wilds, forcing Gladion to battle it with Silvally. During the clash, Nebby flew out of Gladion's grasp and into the air where it reunited with its fellow Cosmog, who had also evolved into Cosmoem. The two Protostar Pokémon flew towards the Altar. Upon arriving, the guardian deities took Sun and Moon and placed them on the 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 Nebby and the other Cosmoem to evolve into Lunala and Solgaleo, respectively. With its newly-gained power, Lunala put Moon on its head and helped fend off the Ultra Beasts that had arrived to attack the Poni Altar. Shortly after, a larger than usual Ultra Wormhole appeared at the Altar with a hand emerging from it. The hand took control of Solgaleo's body. The possessed Solgaleo grabbed Sun with its tail and jumped into the wormhole. Lunala activated its third eye and flew into the wormhole with Moon still on its head.
Some time after arriving in Ultra Space, Lunala got separated from Moon and Sun. At some point, it came in contact with the Ultra Recon Squad, who used Lunala to traverse through Ultra Space via Ultra Warp Ride. At the Ultra Deep Sea, Lunala reunited with Sun and Moon, who had been trapped in the area for six months. After agreeing to work together, Sun, Moon, and Zossie rode on Lunala's back so they could return to Alola. Dulse stayed behind as Lunala couldn't carry more than three people on it. Zossie taught Sun how to use Ultra Warp Ride and told him and Moon about the various worlds the Ultra Beasts come from. After passing through an Ultra Wormhole, the three arrived at the Ultra Recon Squad's home world, the Ultra Megalopolis.
