Tangrowth serves as the character Professor Tangrowth in Pokémon Pokopia.
Professor Tangrowth is a Tangrowth who studies the post-apocalyptic environment and tries to solve the mystery of why humans and Pokémon disappeared. The character meets Ditto early in the story and becomes an important guide during the restoration of Pokémon habitats.
Tangrowth is a Grass-type Pokémon introduced in Generation IV. Its vine-covered design makes the professor's name and role thematically fitting, but Professor Tangrowth is a specific story character rather than a separate species or evolution.
Players may confuse this character with other plant-associated Pokémon such as Torterra or Victreebel. Those Pokémon are not the professor in Pokopia. Tangrowth's role is also distinct from the game’s other named special Pokémon, including Peakychu, Smearguru, Mosslax, Chef Dente, DJ Rotom, and Tinkmaster.
