No one who is half human and half alien exists, in part because the human race has never encountered an alien, intelligent species, let alone try making hybrids.
No such hybrid is every likely to exist. Even if we met a non-human alien intelligent species, their genetic coding is likely to be completely different from ours, probably using different chemicals, and thus completely incompatible with ours, making a viable mix impossible.
Not at the moment
ghosts are not real !

No. He is human.

Venom is pure alien while carnage is half alien half human.Carnage is somehow related to Venom.
A human. Aliens are people from other countries. A human/space alien mix is just this side of impossible... you'd have better luck crossing a human with a jellyfish than any possible space alien. But they would be called "hybrids" if they did exist.
Ben Tennyson is an human/alien hybrid. His grandmother Verdona is an Anodite alien, making him 1/4 alien and 3/4 human. As of now he hasn't shown of possessing any Anodite powers, though.
It's alien!
