Liverpool born, Sergeant Kara Barnes was an expert marksman by the age of 18. She joined up with the Disaster Relief Force after flunking out of school. When Horzine's eminent biologist Dr. Kevin Clamely went rogue and released a horde of bloodthirsty genetically modified mutant Specimens - nicknamed "Zeds" - Barnes was sent in as part of the DRF's first responders after Horzine requested help containing them. She's the Vasquez of the group - grumpy, tough, quick-witted and sharp-tongued.
