Not all fusions work, for example, you can't fuse Zuzumin and Turbomin together. Though some fusions might have components that don't work together if just as regular fusions but work for a tri fusion, example, Turbomin + Zuzumin + Pragmin = Tazugumin! Tho an example of a typical fusion that does work is Ga-kamin, a fusion of Gauzemin and Tonkamin!
