This Bilguss is the First Lieutenant onboard the Vernax Horizon, an alien ship that crashed in Area 27. She was sent out to scout for local lifeforms, but has particular skill in repairing engines. Her dream is to one day command her own ship. Later, when search parties were sent out to locate Trilluna, Zarza was given command of the mission - along with the rank of Captain. It is unknown if she also got her own ship along with the promotion.
Ugh, that was a pretty bad and unexpected crash.
One second, our flight computer was saying everything was fine.
Oh, the repairs are going to take forever.
