SPOILER WARNING!! 3

This is what Naruto looks like in the second story arc.
I have to say that I'm really dissapointed with the up-coming episode (175) it's going to be another filler episode.

This picture of Naruto is taken from the manga. Naruto in the second arc seems to be smarter in terms of his decisions and a bit more mature than he was before. He now has the Oodama Rasengan or Supper Rasengan, which looks to be VERY powerful.
