I'd disagree with the One Piece example. It's justified that Luffy & Co would out-do the Pacifista robots after the timeskip because the Pacifistas were just artificial automatons i.e. they weren't doing any training to become stronger whilst the Strawhat Pirates were all training intensely. As for Hody Jones, was he ever a real threat power-wise ?

Natsu is just Power(-ups) As The Plot Demands in a can. He's a funny character that makes me laugh but Raven is right, Mashima throws logic out of the window whenever he puts Natsu in a fight.
