well you see, thats not exactly what i was talking about. dbz has one story line, and follows that all the way. there are 20 different superman shows, and each of them are different, and have nothing to do with each other. you cant really say the peak of superman, because which one is his peak? which one is the latest and strongest superman? they dont go in order, and when they made one superman show, they didnt really think, hey, lets make it match the other ones. its more like they just stole the superhero from one story, and put it in a different one.
