it'll only be pointless when every1 has the same outlook on it which will not happen because every1 has different views on how things will play out, like i personally believe if and i say IF THE NARUTO CHARACTERS STRIKE FIRST WITH THEIR FULL POWER THE CAN POSSIBLEY AND I SAID POSSIBLEY COME OUT WITH A VICTORY ( all though it'll come with alot and alot of casualties but thats what war is about isnt it)
Any DBZ character would have to be asleep or better yet, completely comatose, for a Naruto character to attack first.
They can sense power levels from planets away. King Kai sensed the saiyans moving towards Earth while on a different planet in outerspace.
Hell, Trunks had hand symbols too. Guess what happened when the androids attacked him.
Goku moved so fast in the fight against Jaycer of the Ginyu force that it looked like he was standing still.
Goku and Vegeta could single (or quadruple, lol) handedly end duality with a stardust cannon destroying God, Satan and maybe even Buddah, just in spite of reincarnation.
Akira Toriyama was off his gourd when creating DBZ and since then, that's why almost all action anime have been either blatantly or subtly based off of it. Even Naruto chakra power-ups look the same when they get srsbusiness.
Look at Rock Lee opening his gates or Naruto using Kyuubi power, look familiar? Yeah, just on a lesser scale. Much lesser. Like comparing a millimeter to a mile.
