Melissa O'Neil as Two, the Captain of the Raza. Formerly known as Portia Lin (on the Galactic Authority's Most Wanted list), Two was revealed to be an illegally-created synthetic human prone to violence. More than any other member of the crew, Two has embraced the opportunity to reinvent herself following their induced amnesia -- though she is still trying to understand her origins and what she is capable of. Two is an extremely capable and deadly fighter, and she'll do anything to protect her crew.
