Son Goku (Japanese: 孫 悟空（そん ごくう） Hepburn: Son Gokū) is a fictional character and main protagonist of the Dragon Ball manga series created by Akira Toriyama. He is based on Sun Wukong, a main character in the classic Chinese novel Journey to the West. Goku first made his debut in Dragon Ball chapter #1 Bulma and Son Goku (ブルマと孫悟空 Buruma to Son Gokū), originally published in Japan's Weekly Shōnen Jump magazine on December 3, 1984,[1] as an eccentric, monkey-tailed boy who practices martial arts and possesses superhuman strength. He meets Bulma and joins her on a journey to find the wish-granting Dragon *.

Initially believed to have been born on Earth, Goku later learns that he is a member of an extraterrestrial warrior race called the Saiyans, which is also the reason for his superhuman strength, and his birth name is Kakarot (カカロット Kakarotto). As Goku grows up, he becomes the Earth′s mightiest warrior and protects his adopted home planet from those who seek to harm it. Goku is depicted as carefree and cheerful when at ease, but quickly serious and strategic-minded when in battle and also enthusiastic to fight. He is able to concentrate his Ki and use it for devastatingly powerful energy-based attacks; the most prominent being his signature Kamehameha (かめはめ波), in which Goku launches a blue energy blast from his palms. Also pure of heart, Goku has frequently granted mercy to his enemies, which has often earned him additional allies in the process (though has also resulted in others taking advantage of his kindness), and he is one of the few who can ride the magic cloud called Kinto'un (筋斗雲, lit. "Somersault Cloud", renamed "Flying Nimbus" in Funimation's dub); which was another element adapted from Journey to the West.

Most of the Dragon Ball fans are so dumb and even before starting a conversation they try to praise goku's *. I don't know why, but I think, may be that was their first anime. According to my opinion, obviously, a ninja like Naruto can't beat Goku. Why, almost all of his attacks are physical and dragon Ball anime is all about physical attacks and destroying planets. But you can't compare the narutoverse by comparing Naruto with goku as he's the main protagonist. But there are people with mental, spiritual and time space powers. Take obito for an example, Goku may destroy a whole galaxy but he won't be able to touch obito, why? Kamui lol ( 5k madara swag XD)

Obito can put him under a gen justu. But it'll take sometime for obito to finish off Goku.

Let's make it quick by considering Madara ,the god of badassness, Goku comes, kamahamehaaa, then madara uses gakido and absord all the energy. Put him under a gen justu and ningendo ! Boom! Saiyan's soul has ripped apart XD

may be he's invulnerable to physical attacks, but how does a creature live without a soul? XD

But the topic's about Naruto vs Goku so yea even Naruto unleashes six path ashura mode he won't make a chance.

Forget about Naruto, hail madara: )

So anyway don't just judge a book by its cover.
