Walkthrough:Pokémon Ultra Sun and Ultra Moon/Part 21

This is the Bulbapedia walkthrough for Pokémon Ultra Sun and Ultra Moon.
These pages follow the enhanced versions, not Pokémon Sun and Moon. The guide for those games can be found here.


Aether Paradise

Hau and Gladion take you back to Aether Paradise aboard Gladion's ship. The Aether Foundation Employees who welcomed you so warmly on your first visit are hostile now, blocking every hallway between the docks and Lusamine.

B1F: Docks

The ferry landing is deserted except for Employees stationed among the storage crates, and you have to fight through them before the elevator will move.

1F: Entrance

Faba is waiting the moment you step off the elevator, and he has no intention of explaining himself. He orders you to turn back, and when you refuse, he draws you into battle himself.

VS Faba

Faba leans on his lone Hypno, so Bug, Ghost, and Dark-type moves settle the fight quickly.

Beaten, Faba admits that whatever the Aether Foundation is hiding must be down in the labs, and he unlocks the elevator to the basement rather than let you search the floor above him further.

B2F: Secret Labs

The hallway leads to two rooms, Secret Lab A and Secret Lab B. Gladion peels off to search Secret Lab A alone, while you and Hau take Secret Lab B and its files on Cosmog and the Ultra Beasts the Foundation has been studying. Employees block the hallway and the doorway into Secret Lab B itself, so expect a fight before you reach either room's notes.

With the labs searched, the three of you head back up to 1F.

1F: Entrance

Wicke catches up to the group and heals your team.

Another wave of Employees is waiting to stop you from leaving, which you fight alongside Hau in a Multi Battle.

Faba is still blocking the way north, and this time he has brought reinforcements of his own.

VS Faba

Gladion fights alongside you against a pair of them in a Multi Battle. Faba fields the same Hypno again, backed by an Employee's Pokémon at his side; the same Bug, Ghost, and Dark-type coverage still works against him.

Being defeated once more, Faba is left with no choice but to surrender the key that allows you to access the far side of Aether Paradise, where President Lusamine's mansion is located.

Lusamine's Mansion

Outside on the grounds, a line of Team Skull Grunts stands between you and the mansion, proof that the Aether Foundation and Team Skull have been working together all along.

Gladion rushes ahead of you to try to clear a path, but by the time you reach the mansion doors yourself, he has already lost his fight with Guzma. As usual, he favors Bug Pokémon, so Fire-, Flying-, and Rock-type attacks are the safest way through his team.

Guzma steps aside once he's beaten, letting you into the mansion.

Inside the mansion, DulseUS/SolieraUM of the Ultra Recon Squad blocks the way further in, asking you to leave them take care of Necrozma, before facing you in battle.

Beaten, DulseUS/SolieraUM let you pass.

Lusamine is waiting beyond them, and she moves to the deepest part of her mansion, where she challenges you to prove your own strength before she leaves for Ultra Space herself.

Gladion and Hau catch up to the room in time to see her go: using the cube holding Nebby, she tears open an Ultra Wormhole and steps through it with Guzma following close behind, ignoring every plea to stop. The wormhole seals itself shut once they're gone, and the cube drops open at your feet. Nebby is still inside it, but it isn't a Cosmog anymore; it has evolved into a Cosmoem.

The Ultra Recon Squad arrives moments later, appalled that Lusamine went through a wormhole for her own reasons rather than to help them. They explain that the way to reach their home, Ultra Megalopolis, where Necrozma waits, is through the power of Alola's own Legendary Pokémon of the sunUS/moonUM.

You spend the night in the manor and the next day meet Lillie outside and Gladion gives you the Master Ball. Head to docks to sail to Poni Island.
