Karen was originally a giant computer screen with a green heart monitor like line that would shake when she expressed audio. Later she was upgraded to a smaller portable monitor on a stick with automated wheels and robo arms and capable of expressing her emotions through green emoticons on her screen. Now in her newest form she is a beautiful robot woman with silver hair, green eyes, and a beautiful face. She wears a white and black button up lace silk shirt and a skirt. Super Computer smart.
