Ultraman Cosmos

Originally said to be the race who sent Mienin and their bio-controllers to Earth. Months later, they sent one of them, Mitoru to Earth with a bio-control crown to kidnap a Mienin to become Gamoran. Once at Kaburaya Island, Lidorias saw her floating orb, but was put to sleep and moved forward. Musashi and a researcher found the orb taking one of the monster and Mushashi to a different location. Once there she explained her plan as a "Final Test" for humans and put the controller on the Mienin and became Gamoran II. After being freed from the alien's power, Musashi became Ultraman Cosmos and battled the monster. After freeing it, Mitoru left earth, knowing that humans had passed this "test".
