The Psycore plays a major role in the Protomon world. It was first introduced in Protomon Gen 1; Beta and Theta, but can be found in all the Protomon games.
"Planet Psycore was discovered when Blight Diro made the Protanium Magnet. Blight tested it out on the driveway to space he made, but it malfunctioned and pulled a local planet to the driveway, which has been called Planet Psycore. It is the core of the Psycore industry, being the building place of the lab."
