Tangrowth serves as the scientist known as Professor Tangrowth in Pokémon Pokopia.
Professor Tangrowth is one of the first important characters Ditto encounters in the abandoned world. The character has taken responsibility for studying the environment and investigating why humans and Pokémon left. That research gives the game’s rebuilding activities a story purpose: restoring habitats helps Pokémon return while also revealing information about the past.
Tangrowth is a Grass-type Pokémon introduced in Generation IV as an evolution of Tangela. Its vine-covered design makes the professor’s connection to overgrown environments especially fitting, although Professor Tangrowth is a story character rather than a conventional human professor.
The name can cause confusion because Pokémon games traditionally use human researchers such as Professor Oak or Professor Rowan. Pokopia reverses that expectation by placing a Pokémon in the professor role. Tangrowth’s work also establishes the game’s unusual premise that Pokémon must manage a world left behind by humanity.
