Ditto meets Tangrowth while investigating the abandoned world in Pokémon Pokopia.
The Tangrowth is known as Professor Tangrowth and has taken on the task of studying the damaged environment. This meeting gives Ditto a companion and establishes the game’s central work of understanding and repairing the world.
Professor Tangrowth is not simply a background character. The character helps connect Pokopia’s story to its environmental mystery, including the question of why humans and Pokémon left the region.
Ditto later helps restore habitats so Pokémon can return and survive. The partnership between the transformed Ditto and Professor Tangrowth provides the narrative framework for exploration, restoration, and the gradual discovery of humanity’s fate.
