Sarah is a Benoi lifeform of the xenopoid variety and one of their scientists. Sarah is also the strongest of all the Benoi, and the most powerful, making her a target of the less savory members of the Benoi who wish to bond with her and use her powers to take over the multiverse. Her biggest rival, and perpetual thorn in the side, is a fellow Benoi by the name of Zoahn. She initially comes to Earth to study and learn about the human race. She eventually meets Mike Clayton and becomes interested in him. So, in order to stay close to him, and observe all that he does, she replaces the Sergenious AI with herself. Later on she grows to like Mike so much that she falls in love with him.
Sarah's apprentice tends to be simple, and somewhat youthful, despite her age. In Benoi years, she is nearly half a century old. In human years, she would be the equivalent of about 18, and even looks the part, having the same general appearance for well over a century, of a young woman between the ages of 18 and 21. Sarah also tends to dress very modestly, choosing to always dress in simple, humble, modest dresses, and other similar outfits, with a simple, grayish white dress, that stretches from her shoulders, to just above her ankles, and is neither tightly fitting, nor does it show any cleavage. Her hair is worn long and straight, and is a beautiful golden brown that glistens like gold, and hangs down nearly to her waistline. It is sometimes worn lose, and sometimes held together with a simple red or blue bow.
