Yes, but she's named for the metal group Pantera, which consisted of just guys. But Cenx saying so is enough for me.The developers confirmed her as a, "she," and call her a, "she." Also, the, "era," part of her name gives off some sort of female vibe.
Angie? Female then.I go for it being hermaphrodite, as that is what most angiosperm plants are.
