Lunar

Lunar is the first cosmeon to appear in a century. He is first introduced in Chapter 13 of Stun II and is described as having "white fur, black paws, yellow eyes, the tips of its ears were black, and it had a red, crescent moon-shaped mark on its forehead."

Being a cosmeon, Lunar is able to control time and space, as well as creating his own dimensions and stopping time altogether. Lunar is also able to free other pokémon from the grasp of Team Rockets' Dark Balls.
