The Golden Demise model seems to push its alien aspect, since throughout most incarnations with a few exceptions he IS the Alien Dragon. the exception was GMK where he's a 3 headed version of a reformed Orochi.



The Devil Model seems to push its Dragon aspect on the Western Hemisphere, looking more like the medieval and Norse dragons. because of this it looks quite generic as this design has also saturated across many fictional genre's and mediums.



an interesting design that has not been taken forth was the Eastern dragon model or the original snake designs from Japanese Myths. a good model would be the yet again the Yamato/ta no Orochi.
