Which Pokémon co-developer is known as Omega Force in Pokémon Pokopia?

Koei Tecmo is the company behind Omega Force, which co-developed Pokémon Pokopia.

Pokopia was co-developed by Game Freak and Omega Force, the Koei Tecmo development team. The partnership combined Game Freak’s Pokémon expertise with Omega Force’s experience creating large-scale sandbox and building-oriented games.

Game Freak’s Shigeru Ohmori conceived Pokopia as a spin-off after considering how players might create habitats for Pokémon. Because Game Freak had less experience with the sandbox genre, Omega Force was brought in to help develop that side of the project.

The answer is sometimes given as Omega Force, but the question asks for the company associated with that studio. Koei Tecmo is the parent company, while Omega Force is the specific internal development group credited alongside Game Freak.
