[quote=@Stern Algorithm][@Dead Cruiser], so if the Star Vampire is infused in an individual's DNA, does that DNA get passed on to the host's children?  Or are do the children only get it after the Star Vampire chooses one to become its next host?  And how long has the Star Vampire been on Earth?  On the one hand, I'm reluctant to have an entire expanding bloodline of metahumans, on the other hand, evil long-lost cousins or brothers or parents make good villains.

The latter option; there is only one Star Vampire, that passes from human to human through natural reproduction.

I would say that the Star Vampire has been on Earth since about 1200 BC, first arriving in ancient Phoenicia.
