Have you ever thought about The bodies of the ninjas? I've done it many times and some times i get pissed off because lets take an example.. Like Naruto and Sasuke! We all agree that they are strong right? but look at their small and skinny bodies! They doesnt look strong at all if they doesnt go inte their power modes ofcourse! Well Almost every ninja is very skinny but still strong i know that im complaining a bit to much but still dont you think that for example Naruto and Sasuke would be a bit larger? Not like A or so but to look Strong and so you can see their muscles!
