In Pokémon Pokopia, what kind of device has DJ Rotom possessed?

DJ Rotom has possessed a stereo system in Pokémon Pokopia.

DJ Rotom is a named Rotom character associated with a stereo system. This follows Rotom’s established identity as a Pokémon capable of possessing electrical appliances and changing form when it inhabits different devices.

The DJ nickname reflects the connection between the Pokémon and sound equipment. Rather than being a generic Rotom encounter, DJ Rotom is one of Pokopia’s individually characterized Pokémon, with a role and presentation that fit the device it inhabits.

Rotom has possessed several appliances across the Pokémon series, including devices associated with washing, heating, cooling, cutting, and ventilation. That broader history can make the exact Pokopia detail easy to mix up, but DJ Rotom’s specific object is a stereo system.
