The game takes place on an island called Pokétopia. There are 10 different Colosseums to battle in. The objective is to win all the Colosseum battles and become the Pokétopia Master.

• Players use Pokémon from their Pokémon® Diamond and Pokémon® Pearl games (sold separately) and battle them on the big screen. Pokémon Battle Revolution is the first title where players can link Wii with Nintendo DS. Players can connect Nintendo DS to Wii (compatible wireless router or Nintendo Wi-Fi USB Connector and broadband access required for online play).
• DS Battle Mode (requires DS systems for all players, sold separately): Four players can gather together and battle while using Pokémon from their Pokémon Diamond and Pokémon Pearl video games. All players use the DS as their controller in this mode, and it uses the same battle interface found in Pokémon Diamond and Pokémon Pearl.
• Players can customize their Trainers in the game.

Colosseum Battle Mode: There are 10 Colosseums (Battle Fields) altogether throughout Pokétopia. Many will need to be unlocked by playing through the others.

Nintendo DS Battle Mode: This multiplayer mode is for those who also own Pokémon Diamond or Pokémon Pearl as well as Nintendo DS systems. Four players can get together and battle while using their very own Pokémon from their Pokémon Diamond and Pokémon Pearl games. All players use the DS as a controller in this mode. The same battle interface that is used in Pokémon Diamond and Pokémon Pearl is used while battling with friends.

Battle Passes and Trainer Customization: Players can create and customize their own Battle Pass by transferring their favorite Pokémon onto the Pass. They can then save the Battle Pass to their Wii Remote™ and take it to a friend’s house to battle with them.
