Kathy, also known as "Katiana" and "Kat". She is a supernatural that appears in the short story Kat and Hunting Kat. She is the only vampire subject of the Genesis II Project.

In Kat, Kathy mentions that her skills come from the training she did. She is a competition-level gymnast, a brown belt in karate, and a second-degree black belt in aikido. She can see in the dark, sense other living beings, and knock out people, when feeding, with her saliva.

When she was little, Kathy lived with her mother and father. She hadn't known what was missing, only that she wasn't a happy child.

Once a month, she was woken up in the middle of the night and taken to a "hospital" where Dr. Davidoff would run several tests on her. These tests would leave her weak and sore for days.

When she was in kindergarten, Kathy met Marguerite for the first time. Marguerite came over and talked to her whenever she was alone and stayed with her when she waited to be picked up.

One day, Marguerite said that she had to leave and asked Kathy to come with her. Kathy agreed. They went to live in Montreal where Kathy became Katiana, Kat for short, and Marguerite became her aunt. After a few years, Marguerite told her the truth about the situation.

In the short story, Kat, Kathy is woken up by Marguerite before she is informed that Vampire Hunters have found them. They then escape their current house/hideout and get onto the streets.

Kathy notices that Marguerite need to feed before they go down an alley. There, she spots a homeless man and tells Marguerite to feed. After Marguerite ate, she slipped the homeless guy $25 before they went to the nearby bus station.

While at the bus station, she saw a woman approach her, calling out her real name. Marguerite then tells her that they will call a taxi before two men approach them. They run until they were trapped in an alley.

After a short battle, they saw a city bus and flagged it down. She learns that the men chasing them were not Vampire Hunters, they were from the Edison Group.
