Its true in a sense that these type of characters keep a story alive and full of opportunity for growth. Who doesnt think the Chuunin exam arc was one of the best arcs in Naruto? Thats because they were fragile and still learning how to b a ninja. This can b applied to all serieses in the anime universe. I bet if DBZ power ranges were restricted to being what they were in the beginning then i believe there would be more room for different arcs. However at this point of DBZs story has actually come to the point that Goku cant fight without destroyin planets around him. DBGT is just one big fail. What do you all think? Do you prefer OP characters or do you prefer non OP?
