What title does Tangrowth use in Pokémon Pokopia’s story?

Tangrowth uses the title Professor Tangrowth in Pokémon Pokopia.

Professor Tangrowth is a story character who studies the damaged environment and tries to understand why humans and Pokémon disappeared. The character meets the Ditto protagonist and helps direct the effort to restore habitats.

The name combines the Pokémon’s species with the academic title “Professor.” This follows a familiar Pokémon storytelling tradition in which professors investigate the natural world, although Professor Tangrowth is himself a Pokémon rather than a human researcher.

Players may confuse the character with Professor Oak or with other Grass-type Pokémon. Professor Oak belongs to the original Kanto games, while Professor Tangrowth is unique to Pokopia’s story. Tangrowth’s role also fits the game’s environmental themes because the plot focuses on rebuilding habitats and helping Pokémon populations recover.
