Pokémon world locations

Waterfall Colosseum is located at the Pokétopia Ancient Falls, surrounded by mountains, trees, the sea, and waterfalls. The gutter's circling the floor are also filled.

The battle theme, Team Battle makes the player pick five out of six party members (all six for Double Battle), and faces them off in one-on-one elimination rounds (two-on-two for Double Battle). This requires one of the highest strategy levels, as the player does not know what Pokémon they face in a round.

The player wins a round if they knock out their opponent's Pokémon first. They must win three out of five rounds to win the battle (two out of three for Double Battle). The round is considered a draw if all the Pokémon on the field are taken out due to moves like Explosion or Self Destruct. If there is a draw between the number of wins, the Trainer who won the last match wins the battle.

Similarly, Level 50 All is available for this Colosseum after the Pokétopia Championship is cleared. Completing Waterfall Colosseum for the first time in Level 30 Open mode unlocks a Pikachu facepaint, a custom Battle Pass with Waterfall Colosseum in the background, and 350 Poké Coupons. It also unlocks 10 items of gear in the shop, two new Rental Passes at Gateway Colosseum, and the next two Colosseums, Neon Colosseum and Crystal Colosseum and in Level 50 All mode, unlocks 23 pieces of gear in the shop and Marina as a Custom Pass Trainer. There is a small chance of Marina wearing a Shiny outfit when battling her in Level 50 All mode.

The default mode of battle here is Single Battle. An option to change this to Double Battle is made available after beating Rank 1 for the first time. The Pokémon and Trainers are not set, except during the first time the player battles there, at Rank 1 Level 30 Open, and the first time the player battles using the Level 50 All Mode, Rank 1 Level 50 All.
