Maria Graber was a Captain in the Resistance. She was the leader of a squad of human survivors who developed a friendship and, later, a romantic relationship with a fellow soldier named Serena Burns. Unknown to Maria at the time, Serena was actually a new model Infiltrator known as a I-950.
Maria was eager to introduce Serena to her commanding officer John Connor — an act which would have resulted in Connor's death. They were about to meet him when, mysteriously, Serena disappeared due to having been recalled by Skynet.
- Graber is one of the few openly gay/bisexual characters in the Terminator universe.
