Zetanna

Zeta alien. Rare group of gray female aliens with big tits and hourglass body and have no hair, usually bald. On a mission to repopulate their dying species by any means necessary. She lives within her large UFO with her other crews from fellow female zeta scientist to female engineers and crews. They all live in a classic saucer that is capable of faster than light travels. She wears a gray skintight space suit, with a glass dome for a helmet. And a device on her right wrist that allow her to translate and communicate other lifeforms.

Their mission is to explore, record, capture, experiment and learn everything she can about other alien lifeforms as they explore the new world. If they are interesting, she'll use one of her advance tools and put them inside special containment room for studying creatures she captures. Her main goal is to find a way to save her species from extinction, so she has to find a humanoid lifeform, who's fertile enough to impregnate a female zeta like herself. She'll even offer herself to bare the male's child if they desire her. She is 72 but looks like 35 or younger and stands 7 feet tall.
