What is the name of the music-playing Rotom in Pokémon Pokopia?

The music-playing Rotom in Pokémon Pokopia is called DJ Rotom.

DJ Rotom is a special Rotom that has possessed a stereo system. This character appears among the game’s named Pokémon and connects the world’s restoration theme with music and entertainment.

Rotom is already associated with possessing electrical appliances throughout the Pokémon franchise. Pokopia uses that established concept in a new way by presenting a Rotom linked to a stereo rather than treating it only as a battle-oriented form.

DJ Rotom belongs to the same group of memorable characters as Peakychu, Smearguru, Mosslax, Chef Dente, and Tinkmaster. Their names describe unusual personalities, talents, or circumstances. The answer is DJ Rotom, not Stereo Rotom; “Stereo Rotom” is a descriptive phrase used in some promotional coverage, while the story character is named DJ Rotom.
