Thia

Thia was a synthetic and the twin sister of Tessa. They were created as a new generation of research synths for the Weyland-Yutani Corporation colony on the planet Genna.

Company forces were sent to capture the Kalisk, but the creature attacked Thia's team, leaving her the sole survivor, and only with her upper torso intact. She later allied with Dek, a Yautja who was also hunting the creature. The pair formed a bond as they faced the threats of Genna together.
