It all depends on the set-up. If it was a flat field and it was just the Spartan with his weapons and a Ninja on it's own, I am thinking that the Spartan would win. Spartans were the best warriors of all time.
Sorry, but Ninjas are trained to walk without weaponsbecause they collect them from their targets as they go!
The Controversy Rages On...
Spartan In a fair fight, yes Spartan would win, but Ninjas don't fight fair.
it is completely circumstantial you can't say that a ninja would kill a samurai every time and vice versa ninja and samurai fought all the time but the ninja wouldn't always win or lose same goes for the samurai
A spartan
A spartan because of his shild and he starts training when he is one
A spartan of course because they went trough trainging of age 7 to 20.
space marine
The ninja turtles would win
In ninjas vs spartan I say ninjas are sift and light in weight were as the spartan is not swift and has lots of weight. So the ninja can win the spartan by hitting running and hiding and hitting again but the spartan by chance can catch the ninja and killing it. Now the spartan 's weapons are not much try about the ninja so many weapons and many deadly moves. At the end think who is the winner. BUT I tell you that THE NINJA is the winner.
Spartan, due to superior weaponry, armor, training, and physical fitness.
The ninja would win. He has the advantage of weapons (swords, shurikens, poisons, ect). He also had an opposable thumb, and human inginuity.
spartan, obviously
It would depend on whether or not the ninja tigers were Siberian or Bengal....but I would have to go with Chuck Norris.
