Well, that used to be her origin. In recent years, Vampirella has reimagined/rebooted/reinvented as the white sheep daughter of one of hell's resident demons. Seems mommie dearest has had some second thoughts about all this evil stuff and sends Vampirella out to undo the whole mess. As before, Vampirella, like Barnabas, suffers enormous vampire angst when she feeds. Unless it's a real nasty s.o.b., of course. Draculon still sort of exists, except it's no longer a planet. It's more like one of hell's suburbs
