Rules: Juggernaut is having a nice day and can use Captain Universe, Trion, 8th Day, and Worthy powers combined. Naruto can use Sage Mode, 9 Tail, 10 Tail, or a combination. Keep in mind that if the universes are very parallel, then the amount of power used to destroy a planet in Marvel is just as hard to do in Naruto's universe. If they are not however, then you can go by Shueisha characters are much stronger than Marvel characters, since a good argument is well very weak DBZ characters can destroyu planets. So far, the greatest feat in Naruto is destroying a city in one hit, or beating taht guy, which Naruto did. Juggernaut's greatest feat is punching through dimensional barriers and going toe to toe with Worldbreaker Hulk. Madara, from Naruto, creates and teleports to new dimensions at will. Now that we have a ground base for measuring them up, the rules are, they can do anything they want to win except beg Goku or the Beyonder to win the fight for them. Since Juggy uses other people's power, Naruto can summon toads, etc, but not things like Krillin's Destructo disc, but maybe he finds a way to summon ninja hounds. BATTLE!
