Mt. Battle

Mt. Battle (Japanese: バトル山 Mt. Battle) is a large mountain in northern Orre that was renovated to become the ultimate challenge for Pokémon Trainers in the games Pokémon Colosseum and Pokémon XD: Gale of Darkness. Challengers must battle through ten areas, each containing ten Trainers (Zones), to pass the challenge—a total of one hundred battles.

The mountain itself is exceedingly large and has a variety of terrain, ranging from basic rocky crags, to the volcanic inside of the mountain, to the lofty peaks. The pathway up Mt. Battle is made with metallic platforms suspended in mid-air with propellers.

Environment
The mountain itself is basically a large, hollowed out, active volcano. There are 99 yellow-outlined circular platforms (each numbered in giant red numbers, ranging from 1 to 99) that serve as the battlefields. Each is connected to the platforms before and after it by either stairs or bridges. These platforms are seen inside and outside of the volcano. There are large fans placed below the platforms, which cool the battlefields and/or keep them suspended in the air. The 100th battlefield is suspended over the mouth of the seemingly active volcano. It is surrounded by metal towers and is much larger than the last 99 battlefields.

Pokémon Colosseum
After purifying all 48 Shadow Pokémon and clearing Mt. Battle in Battle Mode (either Single or Double Battle) with the Story Mode party, the player will obtain a Ho-Oh.

Pokémon XD: Gale of Darkness
If the player clears Mt. Battle without altering their party or taking breaks from their challenge midway through, they will receive one of the three Johto starter Pokémon, all of which know an Egg Move and the -related move of their respective type.

Lobby
The lobby of Mt. Battle consists of a healing machine operated by an attendant along with a PC (essentially a Pokémon Center), a Poké Coupon exchange, a Move Deleter, and the 100-battle challenge reception counter. In, it also contains a Move Reminder.

The prizes available at the coupon exchange, as well as the number of coupons necessary to acquire them, vary slightly by game:

Mew Move Tutor
A Move Tutor in the lobby can teach moves for the cost of 5,000 Poké Coupons. This can only be done after beating the game, but it can be done multiple times. Unlike other Move Tutors, this one does not give the player a direct choice in what Mew learns. Instead, he asks a few questions and then offers a full set of moves for Mew.

This Move Tutor can teach Mew any move it can otherwise learn by TM, HM, or from any other Generation III Move Tutor, plus the moves below:

100-battle challenge
Between each battle, all Pokémon have their HP, PP, and status conditions healed. In the non-Battle modes, however, consumable hold items (such as Berries) are not restored to a Pokémon if they are used in a battle.

Pokémon Colosseum
In Pokémon Colosseum, the 100-battle challenge can be attempted in either Story Mode or Battle Mode. In Story Mode, the opposing Trainers use Pokémon whose levels range from level 15 in Zone 1 to level 60, the highest found in the challenge, in Zone 90 and beyond. The levels of the opposing Pokémon generally increase as the challenge progresses up the mountain, with the exception of one Zone in Area 4. After each of the first nine Areas is a break room containing a PC and an enlisted as part of the Mt. Battle staff. Here, the challenger can change their party, save the game, or be ed by Abra to the foot of the mountain if they wish to quit or rest. They can then resume their challenge later from the start of any completed Area.

Two Time Flutes can be obtained from Mt. Battle. The first is obtained as part of the storyline after defeating Dakim in Zone 10. The second is found in an item chest on the summit of Mt. Battle, just before reaching Zone 100.

The Battle Mode version of the challenge differs significantly from the Story Mode version. In Battle Mode, the challenger can choose to fight Single Battles or Double Battles. Either way, the levels of all opposing Pokémon are set at either level 50 or 100 at the challenger's discretion. However, if the challenger chose to fight at level 50 and they have a Pokémon with a level higher than 50 in their party, all opposing Pokémon will be set at that level. Unlike in Story Mode, the party cannot be changed once the challenge has begun nor can a challenger quit after completing an Area and resume from that position later. The challenger can save their progress, however.

In both modes, the challenger is given Poké Coupons upon completing an area by a staff member in the break room following that area, with the exact amount varying by area and mode:

Note that the reward in Battle Mode is reduced by approximately 13% for every Legendary Pokémon that is included in the party. For example, the use of would cut the reward in Area 1 to 44 Poké Coupons. By using and, the reward drops to 37 Poké Coupons, and so forth.

Ho-Oh
can be acquired at Mt. Battle by defeating all 100 Trainers in Battle Mode (either Single or Double Battle) with their Story Mode party after purifying all 48 Shadow Pokémon in Story Mode. Ho-Oh will then be placed in an open spot in the PC's Pokémon Storage.

Pokémon XD: Gale of Darkness
In Pokémon XD: Gale of Darkness, the general format for the challenge is the same as that of Colosseum's Story Mode. The only significant change is in the levels of the Pokémon used, as they now range from level 9 in Zone 1 to level 70, the highest found in the challenge, in Zone 99. There are also significant jumps in levels between Areas 2 and 3, Areas 4 and 5, and Areas 6 and 7. The rewards for completing each Area in Pokémon XD are as follows:

As in Pokémon Colosseum, the use of Legendary Pokémon will reduce the Poké Coupon reward. However, in Pokémon XD, use of Legendary Pokémon cuts the reward by 15%, leaving the player with 85% of the original coupons. Using two would leave him/her with 72¼% of the original (85% of 85%).

Earth Ribbon and the Johto starters
If all 100 Trainers are defeated over the course of multiple trips to Mt. Battle, there is no additional reward other than the 2,000 Poké Coupons for clearing Area 10. Similarly, there is no bonus for defeating all 100 Trainers with different parties during a single, continuous challenge. However, if all 100 Trainers are defeated with the same party during a single, continuous challenge&mdash;essentially, if Mt. Battle is cleared under the restrictions from Colosseum's Battle Mode&mdash;each of the Pokémon in the player's party will receive an Earth Ribbon commemorating the 100-win streak. Additionally, the player is offered one of the three Johto starters:, , or. They are unique in that they each have one Egg Move and one -related move. The other two moves are standard. All three of the following Pokémon can be acquired by successfully completing the Mt. Battle challenge three times, but each one can only be obtained once. It is not necessary to use different teams of Pokémon for each challenge.
