Pokémon Ultra Sun and Ultra Moon - Pokémon League, Elite Four Molayne, Olivia, Acerola and Kahili

Our in-progress walkthrough for the whole Pokémon Ultra Sun and Ultra Moon island challenge and beyond.

Ultra Sun and Ultra Moon's Elite Four, made up of Molayne, Olivia, Acerola and Kahili, are your final challenge as you bid to become Champion of Alola.

Here on this page we'll explain all you need to know about the story and main events as they unfold here, and as with all pages of our walkthrough we'll highlight any and all trainers, items and wild Pokémon available to catch as well.

Pokémon Ultra Sun and Ultra Moon - Pokémon League, Elite Four Molayne, Olivia, Acerola and Kahili

The Pokémon League functions is the same way as those before it - four elite trainers (the Elite Four...) each in their own room, and no way to exit until you've beaten all four of them.

Working your way round clockwise, you'll face Molayne, Olivia, Acerola and Kahili. Here's how their teams shape up:

Elite Four Molayne

TrainerPokémon 1Pokémon 2Pokémon 3Pokémon 4Pokémon 5Pokémon 6
MolayneKlefki (L.56)Bisharp (L.56)Magnezone (L.56)Metagross (L.56)Alolan Dugtrio (L.57)None

All of Molayne's Pokémon are weak to Fire and Ground, with some even 4x weak to Ground, and many others weak to Fighting, too. He shouldn't prove too much of an issue!

Elite Four Olivia

OliviaArmaldo (L.56)Cradily (L.56)Gigalith (L.56)Probopass (L.56)Lycanroc Midnight Form (L.57)None

Olivia's Pokémon don't have any singular weakness across the board, but you'll do well with Fighting, Steel, Water and Ground-type attacks, and a combination of those should steer you clear.

Elite four Acerola

AcerolaBanette (L.56)Drifblim (L.56)Dhelmise (L.56)Froslass (L.56)Palossand (L.57)None

Acerola's Pokémon are all weak to Dark and Ghost-type attacks, whilst Fire and Rock are a couple common weaknesses too.

Elite four Kahili

KahiliBraviary (L.56)Hawlucha (L.56)Oricorio Red (L.56)Mandibuzz (L.56)Toucannon L.57)None

Kahili is a former trial-goer herself, but she doesn't seem to have learned many lessons along the way. All of her Pokémon are weak to Electric attacks, with four also weak to Rock and Ice, too.

Challenger Hau

TrainerPokémon 1Pokémon 2Pokémon 3Pokémon 4Pokémon 5Pokémon 6
Hau (Rowlet)Primarina (L.60)Flareon (L.58)Alolan Raichu (L.59)Crabominable (L.59)Noivern (L.58)Tauros (L.58)
Hau (Litten)Decidueye (L.60)Vaporeon (L.58)Alolan Raichu (L.59)Crabominable (L.59)Noivern (L.58)Tauros (L.58)
Hau (Popplio)Incineroar (L.60)Leafeon(L.58)Alolan Raichu (L.59)Crabominable (L.59)Noivern (L.58)Tauros (L.58)

Hau has a solid team of varied Pokémon, tailored to counter your starter with his respective Eevee evolution. Ground and Rock are weaknesses shared by a couple of his team, but otherwise this one's all about good rotation and type knowledge. Good luck!

For more on Pokémon Ultra Sun and Moon, head to our main Pokémon Ultra Sun and Ultra Moon walkthrough and guide hub, which includes guides to new Ultra Sun and Ultra Moon Pokémon and Pokédex changes, the Festival Plaza, a list of Global Missions and rewards, an explainer on Pokémon Bank, a dedicated page on Pokémon Competitive Training, including IV Training, EVs and hidden stats, Breeding 6IV Pokémon explained and how to farm Bottle Caps fast for Hyper Training. What's more, we have pages on the Rockruff event for getting Dusk Form Lycanroc and, last but not least, a full Ultra Sun and Ultra Moon QR codes list for adding all Pokémon to your Pokédex.

When Hau's defeated, that's your work here done - congratulations, because it means you're the first ever Alolan Champion!

There's plenty more to see and do as the postgame opens up to you. Explore the rest of Poni Island via Ancient Poni Path's route to the north-west, or dive back into the Ultra Wormhole to catch loads of legendary Pokémon from generations gone by.

For much more, head back to our main Pokémon Ultra Sun and Ultra Moon guide!

There's also trouble with none other than Team Rainbow Rocket, your version's Legendary (Solgaleo or Lunala) to be caught back on Mahalo Trail where you met Lillie, which can now be combined with Necrozma to form Dawn Wings or Dusk Mane and Ultra Necrozma, and then there's your version's Ultra Beast - Blacephalon in Ultra Sun and Stakataka in Ultra Moon - to hunt down in Poni Grove, too!
