There are many interesting characters in 'Ghost in the Shell Stand Alone Complex Story'. For example, Togusa. He is one of the few characters who is still mostly human in a world full of cyborgs. His perspective, his struggle to keep up with his more technologically enhanced colleagues, and his determination to do his job well make him an engaging character. Also, the Puppet Master is quite a thought - provoking character as it challenges the concepts of life, intelligence, and control in the story.
