In the field of Computer Graphics(CG), it's necessary to plastic various character fellow a lots process by shapes, colors, pattern etc. This paper proposes an evolutionary model for automatically generating artificial creatures of various strip pattens. This model offers a novel way to naturally evolve the strip patten of artificial creatures. The evolutionary model use in this research is based on Genetic Algorithms (GA). In this paper, artificial creatures develop into various strip patterns according to the evolutionary model. Later, they can be used as CG animated characters. This model also solves the problem of reducing the time and labor cost for mass production of various characters. It could be used in such areas as the cavalry battle scene in Disney's animation "The bug's Life". In this paper, our approach has two steps. At first, artificial creatures move according to information gathered from the five sense . Then, second based on the GA, evolutionary model, we choose two protprype creatures, which evolve into various strip patterns in alternating generations. Finally, this evolutionary model successfully generates various characters with strip patterns automatically.
