The Ultimate Cyclone is the fusion of the white, red, black, angel, cosmic, super cosmic, metal, relic, Aku, zombie and perfect cyclone. This makes the cyclone have the properties of most of them (excluding some like metal properties), while also gaining the power scale of (aproximately) omniversal, and the ability to stop time. It doesn't appears in the original Battle Cats, instead it appears in a modded version, knowed as Battle Cats Ultimate (BCU)
