Naruto getting powerup is to be expected. Its just a question of how. Hardwork like Goku? well, it turned out Goku is a sayan, a super human race! But the important similarity between Goku and Naruto is their tough childhood. The difference is that you wouldnt guess Goku is Sayan until the writer say so. Kishi on the other hand dropping all kind of hint so we play a guessing game, yet Naruto himself dont care about his origin at all (Goku did, he just accepted a simple lie).
Killing time while waiting for the next chapter. OnePiece, that is.
