The Freak-A-Zoid core is symmetrical, whereas, Del took the Morepheus core and revolved it 360 degrees. In simplier terms, if you were looking at a downward view of the core, draw a line through the center of the core. Then from the center, to the farthest vector point, connect those two point with a circle. From a side view the core would look the same no matter how you viewed it. I don't believe there is any other core that resembles the Morerpheus in its revolved state. However, it is still the Morepheus core in one of its many configurements.
