Pokémon Ultra Sun and Ultra Moon - Altar of the Sunne or Moone, Ultra Megalopolis, Ultra Necrozma

Alter of the Sunne, or Altar of the Moone , and Ultra Megalopolis are your next destinations, as we reach the true climax of Ultra Sun and Ultra Moon's story.

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.

For more general guides and other walkthrough pages like this meanwhile, head back to our main Pokémon Ultra Sun and Ultra Moon walkthrough and guide hub.

Pokémon Ultra Sun and Ultra Moon Altar of the Sunne of Moone

There's little to actively do here, with much of the action you'll face being cutscene-led.

Still, you have your part to play - head up to the Atlar (it'll be Sunne or Moone depending on your version) and stand on the podium on the right.

Soon, the legendary Pokémon you've been hearing so much about will appear - Necrozma! At the same time, your version's Legendary Pokémon - Solgaleo for Sun and Lunala for Moon - will also turn up in the hope of defending you. After a dramatic battle between them however, it's Necrozma that wins out, and fuses with the legendary Pokémon!

You'll now have a battle against a Level 50 version of either Dusk Mane Necrozma in Ultra Sun or Dawn Wings Necrozma in Ultra Moon. It's not too challenging, and you can't catch it here so there's no need to worry about whittling it down slowly. Hit Dawn Wings with Ghost or Dark for 4x damage, or Dusk Mane with Fire, Dark, Ground or Ghost-type attacks.

When you've defeated it, Necrozma flees back into the Ultra Wormhole. Talking to the Ultra Recon Squad, it looks like you're going to have to go after it - by riding their Pokémon into Ultra Space! The controls are a little awkward, requiring motion control (unless you change it, by talking to the Aether Foundation employee in the Game Freak offices back in Heahea City).

Aim for the big white wormwhole when you're in there - you'll know it when you see it - and avoid the others. It takes a bit of time to appear, and you'll need to start again when you go into another wormhole by jumping back the way you came. Before you do that though, try and catch whatever Pokémon appears in the area, as they're often rare (and after the main story this is where Legendaries will appear)!

Pokémon Ultra Sun and Ultra Moon Ultra Megalopolis and Ultra Necrozma

Alright, now you've finally made it into the big white wormhole, you'll arrive in Megalopolis, meeting two more members of the Ultra Recon Squad there, too. They'll point you in the direction of Megalo Tower, which is the only place you can go for now.

Press on, and climb the tower - but be sure to save when you reach the top. When you get there, you're going to face by far the toughest battle of the game.

Waiting for you at the top is Ultra Necrozma, now at level 60, and appearing in a special form that works similarly to Mega Evolution. Every single one of Necrozma's stats are boosted, and it's base stats are already ridiculously high, especially in Special Attack and Speed.

We found it quite literally one-hit every single member of our team, even those with higher levels, and always attacked first thanks to its ridiculous Speed. You may need to 'cheese' it, using a slightly cheeky strategy: ours was to give our Raichu a Focus Sash (you get one from the 'route Kahuna' on Poni Wilds for beating all other trainers there), which allows your Pokémon to endure a hit that would normally knock it out, instead leaving it with 1HP.

With a knockout blow endured, we then Paralyzed Ultra Necrozma with Thunder Wave to halve its speed, letting each of our other Pokémon get off a hit or two before being knocked out. Thankfully, that was enough to do it! The alternative, of course, is popping back to Vast Poni Canyon and fighting some more Pokémon to grind those extra levels. It's joint Psychic and Dragon-type, so Ice, Fairy, Dragon and Ghost and Dark all do double damage, but beware its diverse moovepool which can counter anything!

After you've eventually beaten Necrozma, the Ultra Recon Squad you know will appear, and offer up their Poipole as a gift, seeing as you'll be able to make more use of it as a trainer than them. As it turns out, Poipole actually evolves into the very strong Naganadel when it's levelled up whilst knowing the move Dragon Pulse - handy!

When you arrive back on your planet at the Altar, Lusamine will be back in a little better health, and she gives you three Beast Balls, which are used for catching Ultra Beasts more effectively than regular ones - there are some roaming Alola now!

Next up: Ultra Sun and Ultra Moon - Captain Mina's Trial for Fairium Z, Poni Grand Trial with Kahuna Hapu for Groundium Z

With the main antagonist defeated, that phase of the story is now finally over - but you still have a trial to complete, and the Elite Four to beat! The final trial is from Mina, who casually appears up at the Altar during all of this to challenge you. Next stop is Seafolk Village, to get that underway!
