Which Pokémon serves as the player’s guide and environmental researcher in Pokémon Pokopia?

Professor Tangrowth serves as the player’s guide and environmental researcher in Pokémon Pokopia.

The character is a Tangrowth who has taken on the title “Professor Tangrowth.” After Ditto enters the abandoned world, it meets this character, who is studying the environment and investigating why humans and Pokémon disappeared.

Professor Tangrowth helps establish the game’s central mystery. The world is presented as a post-apocalyptic version of Kanto, with habitats damaged or unsuitable for Pokémon. Ditto is therefore asked to restore different environments so that Pokémon populations can return and thrive.

Professor Tangrowth is not one of the human professors from the main Pokémon games. Professor Oak, Kukui, and Rowan belong to other regions and stories. The name also reflects Pokopia’s unusual setting: unlike the conventional laboratory-based professors, this researcher is itself a Pokémon living among the habitats it studies.
