Who is the Tangrowth character called in Pokémon Pokopia?

The Tangrowth character in Pokémon Pokopia is called Professor Tangrowth. He is a researcher who studies the damaged environment and investigates why humans and Pokémon disappeared.

Professor Tangrowth meets Ditto early in the story and helps establish the game's central rebuilding mission. Rather than sending the player through a conventional sequence of gym battles, he directs attention toward restoring habitats and helping the remaining Pokémon population recover.

The title is a character name, not a reference to Professor Oak. Professor Oak is the well-known researcher from the original Kanto games, while Professor Tangrowth is a Pokémon character created for Pokopia's story. The distinction matters because both characters are associated with Pokémon research and Kanto-like settings.

Tangrowth's role also reflects Pokopia's ecological themes. His research focuses on the environment, while Ditto's practical work changes it. Together, the pair frame the game as an investigation and restoration project within a world altered by the departure of humanity.
