What is the name of the Tangrowth who studies the ruined world in Pokémon Pokopia?

The Tangrowth who studies the ruined world in Pokémon Pokopia is called Professor Tangrowth.

Professor Tangrowth has taken responsibility for studying the damaged environment and investigating why humans and Pokémon disappeared. The character meets Ditto early in the story and gives the player a reason to help restore habitats across the devastated landscape.

The title “Professor” connects the character to the research-focused mentors common throughout the Pokémon franchise, but Professor Tangrowth is not Professor Oak or another human Pokémon professor. Tangrowth’s appearance also makes the role distinctive: the researcher is a Pokémon who has adapted to the abandoned world. As Ditto and Professor Tangrowth work together, they discover records left by humanity and encounter unusual Pokémon with their own stories. The character’s full in-game name is “Professor Tangrowth,” so shortening the answer to merely “Tangrowth” loses the title used by the game’s story.
