On the Pulp Hero idea. Nazi's might imagine themselves as a master race, do you suppose they would take kindly to a Drakon ? Suppose the Nazi wished to capture Gwen and milk her for genetics knowledge and perform a few experiments on her. A hero team that didn't know her true nature might attempt to protect her or even rescue her. That could lead to some nasty plot twist. A four color game would be great fun, four color heros would be appalled at the Drakon , some might even reconsider their CvK.
I'd need to reread the books to put together a Drakon NPC.
