The Colosseum is an online feature that allows players to compete with other trainers locally or online in Pokemon Brilliant Diamond and Shining Pearl (BDSP). Read on to learn more about the Colosseum's link battles and battle formats, custom rulesets, and its location.

Colosseum Features

Link Battles and Formats

First introduced in the 2nd Generation of Pokemon Games, the Colosseum allows trainers to engage in Singles or Double Battles with one other trainer, or have a Multi Battle with three other trainers!

Similar to the Union Room, players can battle using Local and Online Communications, and add a Link Code to narrow down potential challengers.

Multiplayer and Online Features

Single Battles

Trainers can engage in Single Battles with one other trainer, with each player sending out one Pokemon into battle. This is the standard battle format for majority of the game's story.

Double Battles

Trainers can engage in Double Battles with one other trainer, with each player sending out two Pokemon into battle. This battle format is rare in the story and usually reserved for special trainer encounters.

Multi Battles

Multi Battles are a special battle format unique to the Colosseum and operate similar to the story Multi Battles with Cheryl and Riley.

These battles are done with 2 pairs of trainers for a total of 4 trainers, with each player sending one Pokemon into battle at a time.

Custom Rulesets

Unlike Union Rooms, players have the option to select battle rules for Single, Doubles, and Multi-Battles in the Colosseum.

Battle Rules Options

The host or the first person to step on the battle spot will set the custom battle rules, although the trainer can decline to allow the other player to set the rules instead.

Where is the Colosseum?

Available at the top floor of Pokemon Centers

The Colosseum is available on the top floor of every Pokemon Center in the game. Speak to the nurse at the far right counter to enter the Colosseum.

Added in Ver 1.20

The Colosseum was added in the game following the release of Ver 1.20 Patch on February 22, 2022, which also expanded some of the game's existing online features.
