Tangrowth serves as the professor studying the environment in Pokémon Pokopia. The character is known as Professor Tangrowth and investigates why humans and Pokémon left the region.
Professor Tangrowth gives the game a Pokémon-centered version of a familiar series role. Mainline Pokémon games usually present human professors such as Professor Oak or Professor Juniper, but Pokopia makes the researcher itself a Pokémon.
In the story, Professor Tangrowth meets Ditto after Ditto begins exploring the abandoned world. The professor has taken responsibility for studying the environment and solving the mystery behind the disappearance of humanity and Pokémon.
Tangrowth is a Grass-type Pokémon introduced in Generation IV. The species’ vine-covered appearance suits the game’s ecological themes, although Professor Tangrowth is a specific character rather than every Tangrowth in the Pokémon universe.
