The games Pokémon Sun, Moon, Ultra Sun, and Ultra Moon feature the moon as a recurring theme, with Pokémon Moon and Pokémon Ultra Moon both containg Moon in their titles and featuring lunar game mascot Legendary Pokémon in Lunala and Dawn Wings Necrozma, respectively.
Hala's grandson, Hau, then appears in the town and challenges the player to a battle using the Pokémon that is weak to the player's starter. After the battle, Hala takes the player's sparkling stone and invites the player to a festival the following day. The next day, Kukui stops by the player's house again and takes him to Route 1 so he can teach them how to catch Pokémon. Kukui then lets the player train before going to the festival.
Three months later, the player, along with the mother and Meowth, are enjoying their new home on Melemele Island as Professor Kukui enters their home and takes the player to meet the island kahuna in Iki Town to get their starter Pokémon. As they reach Iki Town, the kahuna is nowhere to be found, so Kukui sends the player to the Mahalo Trail in hopes of finding the kahuna. On the trail, the player spots the girl that escaped the lab and follows her to the Plank Bridge.
Some Pokémon species have uniquely adapted to the microclimates of the Alola region, becoming what is known as a regional form of their species. These variant species take on different forms from those of their species in other regions, including a different appearance, Abilities, and more. An Alolan variant of a species is known as its Alolan Form.
Z-Moves are a new type of move in which the Trainer and Pokémon's wishes combine to release their full power. Z-Moves are moves of great power, but can only be used once per battle.
O protagonista masculino, possui cabelos pretos um pouco despenteados. Tradicionalmente, ele usa um boné preto de aba azul. Estampado no boné, está o símbolo de uma meia Pokébola. Seus olhos são cinzas em um tom puxado ao preto. Ele usa uma camisa branca de manga curta, com listras azuis. Diferente dos outros protagonistas, ele usa shorts, que são pretos e com bolso vermelho. Sua mochila é preta com alça azul.
The player and the girl then return to Iki Town and get greeted by Kukui. Kukui introduces the girl as his lab assistant, Lillie, before the kahuna, Hala, returns from resolving a problem on the island. After Lillie explains the encounter she and the player had with Tapu Koko, Hala gets touched by the moment and gives the player the choice to choose Rowlet, Litten, or Popplio as their starter Pokémon. After a short ceremony with the player and the new Pokémon, Kukui gives the player a Pokédex and sends them to their mother to show off the new Pokémon.
Chegando na Aether Foundation, em uma discussão entre a Lillie e Lusamine, descobrimos que não só Lusamine é mãe de Lillie, como também é mãe de Gladion. Ela despreza sua filha pelo roubo de Cosmog, que estava em sua posse, e seu filho pelo roubo de Type: Null, criação da Aether Foundation. Lusamine invoca Nihilego usando o poder de Cosmog, trazendo consigo mais UBs, que atacam as ilhas de Alola. Tapu Koko é ajudado por Hala a defender a ilha de Melemele do UB-02 (que varia de acordo com a versão que estiver jogando). Após distorção na energia, Lusamine e Guzma seguem para o Ultra Espaço com Nihilego, deixando Cosmog gravemente ferido e desgastado, que Lillie descobre ter se tornado o Cosmeom ao evoluir, quando usou suas forças para abrir o portal. O local de onde as UBs estão vindo se chama o Ultra Espaço (Ultra Space) e poderemos acessar esse local usando o poder do lendário. Contudo, para acessar, será necessário termos Nebby (como Lillie chama o lendário) conosco, para criar Ultra Wormholes (ultra buracos-de-minhoca). Nebby, aparentemente, é como o lendário é conhecido - pois trata-se de uma Ultra Beast também.
The trio then spot Team Skull and Guzma in front of where they need to go. Gladion immediately takes on Guzma while Hau and the player take out the Grunts. After taking out the Grunts, Guzma takes down Gladion and the player takes his place in battle. Guzma gets defeated by the player again and is forced to let the team move onwards. The player then runs into Lusamine and Lillie. The player witnesses a darker side of Lusamine and learns that Nebby is being sacrificed to bring back the beast from earlier. Lillie tries to reason with her mother, but fails to do so, resulting in the player going after Lusamine.
As the player progresses through the game, they will become able to use Festival Plaza. Festival Plaza allows players to see other people playing near them, or other players that are connected to the internet to battle or trade. By talking to people and listening to their requests in Festival Plaza, players can receive Festival Coins. Festival Coins can be spent on stores in the plaza, and eventually rank up their Plaza.
Each trial has a Trial Captain who provides guidance to trial-goers. All of the Captains are Trainers who undertook trials in their own island challenge a few years earlier.
In order to use a Z-Move, a Trainer needs two items: a Z-Ring and a Z-Crystal. A Z-Ring is a band worn on a Trainer's arm. A Z-Crystal must be set into the Z-Ring, and if a Pokémon holds a Z-Crystal of the same type, they will resonate with each other. If the Pokémon then knows a move corresponding to the Z-Crystal's type, it will be able to use a Z-Move. All Pokémon can use Z-Moves, and there are Z-Moves for each of the 18 types. There are also Z-Moves that can only be used by specific Pokémon.
Após isso, Plumeria, que usa Golbat e Salazzle, irá roubar Cosmog de Lillie e Hau. Então, Gladion da Team Skull te encontra e te desafia a uma batalha, usando Type: Null, Crobat e Sneasel, contudo, é descoberto que ele está do seu lado e te ajuda a recuperar Cosmog da Aether Foundation, que está trabalhando com a Team Skull.
At Aether Paradise, the player and Hau meets the Aether Foundation President Lusamine and learn that the company is responsible for making Aether Paradise a sanctuary for abused Pokémon. In the middle of the meeting, a weird creature from another universe attacks the player and after a short battle retreats to its own world. Lusamine becomes interested in the odd creature and sends the duo to Ula'ula Island to complete their island challenge.
After defeating Hala, the player receives another Z-Crystal and is given a Ride Pager in order to ride Pokémon like Tauros in the Alola region. The player makes way to the next island, Akala Island. On Akala Island, the player attends the trials of Lana, Kiawe, and Mallow before battling island kahuna Olivia. On Akala Island, the player once again encounters Team Skull and encounters new people like a neglected member of Team Skull named Gladion who owns a Pokémon called Type: Null, and Hapu, a wanderer traveling the region with her Mudsdale. After defeating the island kahuna, Faba invites the player and Hau to Aether Paradise.
Pokémon Sun and Moon were followed in 2017 by Pokémon Ultra Sun and Ultra Moon, which are set in an alternate storyline.
When the player meets up with Ilima, two Team Skull Grunts appear, but they appear to be minor threats to Ilima. After a quick lesson from the player and Ilima, the Grunts flee and Ilima heals the player's Pokémon before challenging the player to a battle himself. After the battle, Ilima gets impressed by the player's team and allows the player to attempt his trial. On the way to Verdant Cavern, a wild Delibird drags the player to the Berry fields as more Team Skull Grunts are causing trouble with other people. The Grunts get defeated by the player, and they announce to mess with Ilima's trial.
