12 Years ago, a gigantic demon Ape (Oozaru) attacked the Leaf Village of Konoha !! Now a young boy Named Goku, struggels to fufil his dream, of becoming Hokage !! However Goku has a secret, one not even he knows, that HE is the Oozaru, resposible for the slaughter of many of the villages Ninja, and untold destruction !!
10 Years ago, a young bot names Uzumak Naruto, lost his grandfather to a 9 tailed demon fox (Kyuubi) his grandfather left him one thing, the 4 star Dragonball, which naruto hold dear ! Now a young girl named Bulma, is searching for the Dragonballs to fufil her wish of a boyfriend, she Takes Naruto with her in exchange for his Dragonball. Now Naruto is in for the adventure of his life !!
This is a what if scenario, what if two of the biggest Anime/ Manga character sof all time...switched places !! Naruto, training with Matser Roshi, Battaling Tenshinhan in the 22nd Tenakichi Budokai, Climbing Korin Tower and Locking horns with the red ribbon army !! Goku, traning with Kakashi sensei alongside Sasuke and Sakua, Fighting for his life againt Haku, enduring the chunin exams !!
Now the two are also very simlar, both hardheaded, dumb, and very powerful, and both have a terrible secret !! The two will play out each others life until the end of there series ( end of Dragonball, End of Naruto) Things would be simialr, but how would the two cope? What would happen ?? What major differences would there be ?you decide !!
well if the rules from both universes stay with their respected character then naruto would die when vageta comes to fight him and goku would become hokage in a year. but if they swap rules, then the kyuubi would be insane, and naruto would become increadibly powerful way faster than goku did because he has such a huge amount of energy inside him and would learn to controle it so when buu comes out he would simply vaporize it, and goku would become an insanely powerful ninja but not the strongest...until he finds out that he is oozaru and learns to bring it out and condence it (similar to ssj4) that combined with the sage mode he will learn later (thats assuming that they are following the same story) then he will be about the same as naruto.
so the short version, if the rules swap with the characters then naruto would become way more powerful than anything in the dragon ball universe, and goku would become about as strong as naruto is atm. thats also assuming that naruto would be a sayan if not then he wouldnt become as strong but still insane
in my opinion naruto would die at the start, he would try to pick up the car bulma is in find out he cant, get out from underneath it and get shot in the head, end of naruto lol. Goku as naruto erm he'd kill everyone with one hit :L, so not a good story and the story would end in one episode for both because naruto would be dead and goku would have killed all the villains. END
Unless you mean naruto had gokus powers and goku had narutos thn basically its the same shows with different faces as the main character
