Pokémon world locations

Mt. Moon (Japanese: お月見山 Mt. Otsukimi), formatted as Mount Moon in Pokémon Brilliant Diamond and Shining Pearl, is a mountain located in northern Kanto, between Pewter City in the west and Cerulean City in the east. It also provides access to Mt. Moon Square in Generations II and IV. Climbing does not seem to be possible; to get past it, travelers always need to travel through the caves.

Mt. Moon is known for being one of the few places where wild Clefairy can be found and for its frequent meteor falls. The shards of meteorites that fall here become Moon Stones, which explains the mountain's name. The mountain is also known for being home to Pokémon Fossils. Brock digs for Fossils here in his spare time.

Geography

Generation I

In the Generation I games, Mt. Moon's interior is a large cave spanning three floors. Being the first cave that the player will come across with, Mt. Moon has a very long and complex structure. The first floor contains several ordinary Trainers, while the basement floor contains members of Team Rocket who are trying to steal Fossils from Mt. Moon to market them for money. On the player's way out to Cerulean City, the player will find two Fossils, the Dome Fossil and the Helix Fossil that a Super Nerd claims to have found first. After being defeated in battle, the Super Nerd lets the player choose one of the Fossils while he will take the other one. In Pokémon Yellow, after the player obtains one of the Fossils, Jessie and James will appear for the first time and battle the player. However, they are not referred to as such in-game, sharing their Trainer class with that of ordinary Team Rocket Grunts.

Players will first encounter wild Clefairy here at Mt. Moon.

Generation II

In Pokémon Gold, Silver, and Crystal, Mt. Moon has dramatically decreased in size from Pokémon Red, Green, Blue, and Yellow. It now has only one base floor with a couple of connectors. It is also a spot where the player's rival is training near the entrance and he will battle the player for the sixth time during the game.

When entering through the Pewter City entrance, there are two possible paths: one in the eastern direction and another one in the southern direction. By traveling south and then east, the Cerulean City entrance can be found. However, by traveling east from the Pewter City entrance, the player will end up at the northern side of Mt. Moon, where Mt. Moon Square, its summit, is located. By traveling south in Mt. Moon Square, and entering the southern cavern, there will be a ledge which can be jumped to instantly access the Cerulean City entrance.

Mt. Moon Square is an area in the heights of Mt. Moon. On Monday nights, two Clefairy will dance and pray to a large Moon Stone in the square. By interrupting the dance and breaking the stone using Rock Smash, Trainers can always find a Moon Stone below the rock. There is also a small shop here that sells a variety of goods.

Generation III

Mt. Moon's incarnation in Pokémon FireRed and LeafGreen is very similar to the original from the Generation I games. The only major change done for the remakes is the items found within the cave. Another addition is a man who is excavating for Fossils in the north-eastern corner of the first floor. He is a friend of Brock and is a source of one of Brock's Fame Checker entries.

Generation IV

Mt. Moon's incarnation in Pokémon HeartGold and SoulSilver is essentially intact from the Generation II games, but with updated graphics enhancing the scenery and depicting its mountainous nature more accurately. The only significant changes are in Mt. Moon Square, where four Clefairy will appear instead of the only two that appear in the Generation II games, and the background music being changed to つながりのどうくつ Union Cave, a Johto theme, from イワヤマトンネル Rock Tunnel, a Kanto theme, which is the background music that plays here in the Generation II games (the latter being itself a remix of おつきみ山のどうくつ Caves of Mt. Moon from the Generation I games).

In the side games

Pokémon Pinball

Mt. Moon appears on the Blue Field as Area 1. Catchable Pokémon include Rattata, Ekans, Clefairy, Zubat, Paras, and Geodude.

In the anime

Main series

Mt. Moon is depicted as being bigger in the anime than it is in the games. It can be clearly seen from as far away as Pallet Town.

Mt. Moon first appeared in Clefairy and the Moon Stone, when Ash, Misty, and Brock encountered a scientist named Seymour and stopped Team Rocket from stealing a giant Moon Stone. Brock also caught himself a Zubat here.

Mt. Moon was briefly mentioned in The School of Hard Knocks, when Brock pulled out a bottle of Mt. Moon spring water from his backpack.

In A Real Cleffa-Hanger, Ash, Brock, Misty, May, and Max passed by Mt. Moon on the road to the Battle Factory. They helped a lost Cleffa reunite with the other Fairy Pokémon before Misty headed to the Cerulean Gym and the rest of the group resumed their journey to the Battle Factory.

Pokémon

Caught Pokémon

Pokémon Origins

Mt. Moon was briefly seen in File 2: Cubone, as Red recalled battling a Fossil-crazy Super Nerd there.

In the manga

The Electric Tale of Pikachu

Mt. Moon appeared in Clefairy Tale, where Ash traveled there in the hopes of catching a Clefairy. After three agonizing weeks in the wilderness, Ash and Pikachu accidentally followed a Clefairy into an occupied Onix nest. After escaping from Onix, they encountered Professor Oak and Bill, who had come to research the local Clefairy. Together, they witnessed a Clefairy evolution ritual before parting ways, with Professor Oak giving Ash a Pokédex upgrade to commemorate their encounter.

Pokémon Adventures

Red, Green & Blue arc

Mt. Moon was first mentioned by Professor Oak in Gyarados Splashes In!, telling Red and Misty that Team Rocket was trying to find a Moon Stone from there. In Raging Rhydon, Red and Misty entered the mountain, and encountered a group of Team Rocket Grunts led by Koga. During the battle that ensued, Koga forcibly evolved his Rhyhorn into Rhydon to fight them, but the two Trainers were able to escape when Red collapsed part of the cave. Once he and Misty had exited Mt. Moon, Red revealed that he had found a Moon Stone from the rubble created when he had collapsed the cave.

Yellow arc

In Ponyta Tale, Red received a challenge from Bruno to come battle him on Mt. Moon. However, when he didn't return in a month, Brock went to investigate the mountain in The Primeape Directive. In Putting It on the Line...Against Arcanine, Brock contacted Blaine, informing him that he had discovered an empty ice mold in the shape of Red, with its backside broken open.

In a series of flashbacks spread out across the arc, it was revealed that Red had battled against Bruno, feeling truly challenged and excited for the first time since becoming a Pokémon League Champion two years earlier. However, the battle was interrupted by Lorelei and Agatha, who placed Bruno under mind control and wanted to know if Red had the Earth Badge, which they needed for their plans. When Red refused to help them, the three Elite Four members attacked Red together, defeating all of his Pokémon and encasing him in ice. Only Red's Pikachu, Pika, was able to escape. Red was later freed from his icy prison by Giovanni, who also gave him a set of special unexpiring Evolution stones to be used on his Eevee.

In Take a Chance on Chansey, Super Nerd Miles revealed that he and his friends had found Red frozen in ice a month earlier, as well as a fragment of Red's glove. He had afterwards been approached by Agatha, who had tasked him with capturing Pika, but he had failed.

In the TCG

Mt. Moon as depicted in the TCG

In addition to its presence as a card, Mt. Moon has been featured in Area 3 of Expansion Sheet 1 of the Vending Machine cards. The Pokémon shown in this area are Geodude, Paras, Clefairy, and Zubat.
