More on the Ride Chemy Cards that Kudo uses, the Unicon Ride Chemy Card has a Fantastic attribute, and has purification abilities. The Sun Ride Chemy Card on the other hand, has a Cosmic attribute, and it has inexhaustible energy. That said, only a limited number of alchemists can control both Fantastic and Cosmic attributed Chemy at the same time.
