Luz is a shy and nervous little cyan astronaut. He is knowledgeable on basic medical things and often spends his time in the Medbay. As a crewmate, he tries to get his tasks done quickly and stay around others he trusts. However, he can be a bit oblivious and too trusting towards many.

As the impostor, Luz is really nervous and feels bad about killing others. He spends most of his time sabotaging things around the ship. When he must kill, he usually makes it fast and tries not to cause his victims too much suffering.
