When Duncan bought out Playmaxx, they inherited a large number of Cold Fusions. The inventory was part of the settlement Playmaxx received in Playmaxx vs. Custom Yo-Yo patent infringement lawsuit. The Cold Fusions were in various stages of completion. Some were still natural aluminum, some anodized, some complete with logo.
Duncan first sold out the completed Cold Fusions. When those ran out, they for the first time put the Duncan brand name on the Cold Fusion. Pictured here is a Cold Fusion from the second Duncan run. The red anodize varied a little bit on these, from middle to darker red. This one is very dark.
