I think that these stories are pretty screwed up from the beginning, it's not because of the narration but because of the power system it has. There is a reason why the shonen avoid listing the power that the characters have so much, it is because it limits the imagination and the variety to only the one with the greatest combat power wins. In one piece something similar happened in Water 7 with CP9, the creator of the manga realized his mistake and never again put a number on the power of people. And for the last example Dragon Ball did that and had to implement divine ki in order to fix a tremendous mess with the power system, but there are still gaps.
