This paper describes the creation of unique negative avatar/character from the children imaginations. These avatar/characters will eventually be used in computer games for healing purpose. For gathering children ideas about evil character, we used sketch/drawing strategy to collect data effectively. A survey was conducted from 100 children of age group 6-16, from different schools of Pakistan. In the survey children were asked to draw their imaginative enemies on a paper. Collected drawings were then categorized and grouped on the basis of similarities of concepts of enemy features and structures by observing each drawing. We are in the process of designing an algorithm that will extracts features from all sketches and generate feature books for each corresponding feature. In the next step another algorithm will be designed to create unique character from multiple feature books by using random selection. This process will create unique avatar/character for the healing game environment as well as ensure children participation in its creation.
