Superman is the ultimate hero because of the following reasons:
1) More range, he can travel planet to planet. 2) More power, he can carry a mountain. He-man too can do that but he needs power from somewhere ;) 3) has built in features for many things :)). he need not have a place to stick his web like spiderman. batman can only jump from up to down and that too with his wings. He-man does not fly.
Lastly contradicting to what i said, if you think of hanu-man, he is better than the best(Superman). Its just that he does not have enough publicity. :) Hanu-man can do anything he wants :).
