Artificial intelligence in charge of New Mobotropolis. Later creates her own Mobian form as a Lynx. NICOLE possesses many of the traits of a living being, and is fully regarded as such by her friends. She is able to express concern for others, and is not without the ability to mock or express defiance. However, she is at times out of touch with this part of herself, reverting to the more logical thought processes of a machine. Originally this sort of behavior was all NICOLE was capable of, with logic being the only motivation behind any decision. Despite this, she is capable of appreciating beauty and of helping others in times of difficulty.
