What nickname is given to Tangrowth in Pokémon Pokopia?

Tangrowth is called Professor Tangrowth in Pokémon Pokopia.

Professor Tangrowth is a character who studies the abandoned environment and investigates why humans and Pokémon left the region. After Ditto begins its journey, Professor Tangrowth helps frame the restoration effort as both an ecological mission and a mystery.

The character is a playful example of Pokopia giving Pokémon distinctive roles and identities. Instead of appearing only as battle creatures, Pokémon can act as researchers, chefs, artists, builders, or community members. Professor Tangrowth's name combines the familiar academic title “Professor” with the species name Tangrowth.

Players may confuse this character with Professor Oak, the famous human Pokémon researcher from Kanto. Professor Oak belongs to the traditional Kanto games, while Professor Tangrowth is a Pokémon character created for Pokopia's post-apocalyptic story.
