The Crow'd Fusion Nucleus is a special version of the Cold Fusion Nucleus comprised of an anodized red half and and an anodized blue half. It is named in honor of Scarecrow. Only fifteen pieces were manufactured, making the Crow'd Fusion Nucleus one of the most collectible ProYo yo-yos ever produced. Of course, it comes packaged with the same exact set of goodies as the standard Nucleus.
