Enevhar Aldarion
Hero
Ventress isn’t human, and it’s easy to tell by her physical appearance.
On appearance, Omega’s skin looked darker in this episode.
And, as I mentioned before, Omega clearly ages. Compare her appearance in this episode with season 1.
And yet she is older that all those fully grown clones around her, while still looking like a child. She may not even be a clone in the true sense of the word and was rather made using the DNA/genetics of more than one being. And we already know that there are several species in Star Wars that can procreate with humans, so mashing up stuff from a few different samples to make Omega, does not seem too far fetched.
