DJ Rotom is the special Pokémon in Pokémon Pokopia that possesses a stereo system.
DJ Rotom appears among the distinctive Pokémon that Ditto encounters while rebuilding the world. The character's identity is based on Rotom's established ability to possess electrical appliances, but Pokopia gives that idea a musical form by placing Rotom inside a stereo system.
The name can be confused with generic Rotom forms or with other music-themed Pokémon concepts. In Pokopia, DJ Rotom is a named character, just as Chef Dente is a named Greedent and Smearguru is a named Smeargle. The character helps connect the game's restoration story with collectible and decorative objects, showing how Pokémon abilities can shape the rebuilt environment.
