Which Pokémon acts as a professor and studies Pokopia’s environment?

Tangrowth acts as Professor Tangrowth and studies Pokémon Pokopia’s environment.

In the story, Ditto meets Professor Tangrowth after entering a world that humans have abandoned. The professor has taken responsibility for investigating the damaged surroundings and understanding why the land became unsuitable for Pokémon.

This character is unusual because Tangrowth is not simply a wild Pokémon encountered during exploration. It has adopted a scholarly role and helps frame the game’s environmental mystery. Together, Tangrowth and Ditto investigate the abandoned world while working to restore habitats.

Tangrowth is a Grass-type Pokémon introduced in Generation IV, but Pokopia gives it a distinctive narrative identity through the “Professor” title. That title is not held by a conventional human Pokémon professor such as Oak, Elm, or Rowan.
