Dominant, Absent and Alterntative Representations

As we are doing childrens tv drama we decided the representations of particular social groups should be dominant as this is appropriate for the target audience. We have a young target audience so representations of characters shouldnt be alternative, as they may find this confusing. However the idea for our tv drama is about a boy who is a superhero, but he is not a typical superhero with great powers. He finds it difficult to use them, so this wouldnt be seen as a stereotypical superhero, however he is a sterotypical young boy, the same with our other characters they would all be sterotypical young kids.
