given the fact that a ninja has stealth as well as a killer katana and shuriken the ninja would win hands down the Apache would turn around to find a sword through his gut and then his head on the ground end of story
An Apache is also a helicopter, I don't think a ninja could kill one.
The ninja turtles would win
The ninja were very fast,having strong weapons,also having some supernatural powers like shapeshifting,invisiblity and flying so it is easy to conclude that ninja would win
Spartan In a fair fight, yes Spartan would win, but Ninjas don't fight fair.
The ninja would win. He has the advantage of weapons (swords, shurikens, poisons, ect). He also had an opposable thumb, and human inginuity.
Apache
It would depend on whether or not the ninja tigers were Siberian or Bengal....but I would have to go with Chuck Norris.
The Avengers. And it wouldn't be close.
The ninja could sneak up on the samurai. But if they both knew the each other was there, it would depend who trained better. But I would bet on the ninja since it has throwing stars.
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
ninja assasin would slit his throat and sh1t down his throat to stop it instantally regenerating
Batman without a doubt. Batman knows how to do everything.
Nami
