Ruined Kingdom Power Moons are what you'll find on this page, where we detail each Ruined Kingdom Power Moon and its location in the region with accompanying screens for extra clarity.
This is where to find Ruined Kingdom Moons then, but for other regions you can cycle back to our Power Moon locations guide hub, or our main Super Mario Odyssey guide and walkthrough hub for much more.
There are 4 Power Moons to find until you reach the end-game, with one involving Peach and then some more.
1. Battle with the Lord of Lightning! (3 Moons)
To obtain this Multi Moon, you will need to defeat the giant dragon known as the Lord of Lightning. Use the Spark pylon to reach his tower, avoid his electrical rings, and the shockwaves. Pull the rings off his head then Ground Pound his head. Repeat three times to gain your prize.
2. In the Ancient Treasure Chest
From the Odyssey, approach the first flight of stairs. Look to the left of the stairs and you'll see a line in the bricks that can be used as a ledge to shimmy to the other side. In the chest you'll find a Moon.
3. Roulette Tower: Climbed
Use the P Switches to stop the moving blocks in the right positions to cross each 2D section. There's a red switch to Ground Pound if you get it wrong. Ascend to the top of the tower to claim this Moon for your own.
Need more help? Our Super Mario Odyssey guide and walkthrough goes through every objective in each Kingdom, while our Power Moon locations can help you track down the likes of Cascade Kingdom Power Moons, Sand Kingdom Power Moons, Metro Kingdom and New Donk City Power Moons and more collectables. We also have Purple Coin locations for each Kingdom, and if you want to know what to spend it on, we have a hats list, outfits list, stickers list, a souvenirs list as well as a music list to kit out the appearance of both Mario and the Odyssey. Once you've finished the game, check out the free Balloon World update, too.
4. Roulette Tower: Stopped
Halfway through the tower, you'll encounter a section with some red and green Koopas patrolling. Jump up onto the far right set of ? Blocks, then jump on the Red Koopa on the top left platform. Send its shell flying to the left. It will then move around to the other side, destroying a brick wall.
5. Peach in the Ruined Kingdom
Head to the platform with the now sleeping Lord of Lightning. Talk to Peach to collect this Moon. This Moon can only be collected after the story is complete.
Other Ruined Kingdom Power Moons you can unlock
As well as the above Moons that appear when you clear a Kingdom for the first time, there is yet another set that you can collect later in the game. Be warned the following contains some light spoilers.
When exploring each Kingdom previously, you may have noticed a giant, grey block that seemingly has no purpose. It's this object you must find once you have completed the game that'll give you even more things to do.
The above video by Nintendo Life explains this in more detail, but in short - complete the game, find the block in any given Kingdom, and more Moons will be available for you to find.
We won't detail these extra Moons here, but the number of these extra challenges available in each Kingdom varies - just like the amount of Moons you could find to begin with. Good luck!
