Kara is on the shorter side, standing a few inches over 5 feet tall. Her auburn hair is kept long, though she often braids it to keep it from getting in her face at the worst possible time. Her skin is pale with many freckles - she burns easily if out in the sun. Kara's blue-gray eyes are always scanning the world around her, seemingly on constant lookout for trouble. Her body is slender, though she has demonstrated impressive athleticism and flexibility at various times while trying to survive, giving rise to speculation that she used to be a gymnast. She looks to be in her mid-twenties.

Kara has a knack for finding ways of avoiding trouble, which has caused the Enclave to give her the role of guide. She is typically utilized when people are looking to avoid trouble rather than make more. Her first instincts seem to be to calm things rather than escalate. That beings said, she does take serious chances being a gambler.
