What is Professor Tangrowth studying in Pokémon Pokopia?

Professor Tangrowth is studying the environment in Pokémon Pokopia.

Professor Tangrowth is a Tangrowth who has taken on the role of an investigator and researcher in the abandoned Kanto setting. The character studies the damaged environment and works to understand why humans and Pokémon left the region.

Tangrowth’s research gives the player a narrative reason to restore habitats. As Ditto helps Pokémon and rebuilds the landscape, the pair gradually uncover information about the world’s collapse and the fate of humanity. The story therefore links practical building tasks with a larger mystery.

The name can cause confusion because Professor Tangrowth is not a human professor such as Professor Oak. Tangrowth is the Pokémon species and the character’s title-like name. The research is also broader than Pokémon biology or evolution: it concerns the condition of the world and the events that made it difficult for life to remain there.
