The second form from CV1 was basically the basis to the forms we'd see in X68000/Chronicles, RoB, SotN and DoS. The only difference is that the others basically are graphically superior versions, but you can tell how they were built upon each other. How the one from X68000 looks, it resembles the CV one(giant demonic creature with bat wings between it's arms), and acts exactly the same(the whole jumping animation). Then with RoB(which is basically the same oen seen in SotN and DoS), it acts similar as well as keeping some of the X68000's features, like the small curved horns. Those seem to be the only consistent forms that Dracula's used more than once. His Bloodlines form doesn't look like his CV3 form, nor does his CoD form look like his SCV4 form. Different looking Draculas, different looking demons, be them just "Skull-faced"(SCV4), a Charun-looking demon(CV3), a prickly crotch-mouth demon(Bloodlines), a giant demon with four angel wings(CoD), A white haired purple demon with Alien-like tendrills(CotM), and so on(so on...).
