Ninja vs Zombie

Of all the scenarios that have given me cause one to ponder
In Games both intellectual and physical and entertainments both popular and refined we find ourselves coming particular again and again to confrontations fights that pit strength against speed or brute force against cunning.
for me the confrontation embodies that question perfectly is

Who would win in a fight of Ninja versus Zombie ?

It this fight the master of the stealth martial arts, the Midnight Black cloaked Ninja is pitted against a Classic of the Undead the Zombie.
Who will triumph ?
Its important that we get some of the details fixed before we start the fight to avoid any confusion later.

The Ninja

The Ninja will be a fully trained and equipped, they aren’t exactly a Ninja Master but they are no novice either.
As a veteran of veteran of a few missions this Ninja warrior is adept in the Martial Arts. Some of the more well known eastern martial arts such as Judo and Karate, allowing an unarmed Ninja powerful strikes and blocks.
They also have some experience in the lesser known skills of Ninjitsu, years of training in these skills have trained this Ninja in skills such as escape and evasion in both urban and rural settings and torture for information and revenge .
Lets us also say our Ninja champion is a male aged 25 years with good physical fitness. He comes from a Japanese rural village, he is above average for the population in intelligence and height, at about 175 cm. tall. His weight is a robust 70 kg. We can allow him another 10kg gear that could be 5kg clothes or food and another 10kg of Ninja equipment and he would still only be about 90kg.
Exactly which weapons he will choose for his mission will be critical

The Zombie


The opponent,
A category 1 human "Necro" Zombie ( Humanoid ) *
Either recently reanimated from fresh or recently released from a high quality storage facility.*
With similar height and weight about 173cm and 70kg.
Of course the non gender pronoun "It" more correctly describes the Zombie rather than "He" or "She" As the former sexual human organs are now necrotic, this creature now only "reproduces" through the Infection.
It carries no equipment or weapons and is capable of using only the most primitive tools. However Its filthy jagged Finger Nails and Teeth make potentially lethal weapons.

The Fight


Obviously difficulties arise should the Ninja not wish to engage the Zombie in combat. With greater speed and dexterity all other things being equal the Ninja should be able to choose the time and place of the fight. Unless his had is forced by circumstances or terrain the Ninja can easily evade the clumsy and staggering "Walking Dead".
No such problem exist for the motivation of the Zombie, hateful of all life it will relentless seek to spread the infection.
But that doesn’t make for much of a fight. For the sake of a scenario we will assume that by order of the Ninja’s master a certain door must be opened and all beyond it in a room a man waits, A guard perhaps, He must be killed. This man never eats never sleeps and never leaves.

The Ninja will soon find to his dismay that many of his traditional Ninja tricks are of little use. Being Undead the Zombie is immune to pain and fear, making any Ninja mind tricks will futile.
Many of the most devastating Martial Arts attacks would be also be useless, Pressure points attacks at vital meridians are only learnt and described for humans.
Even the Ninja’s fabled ability to seem to disappear would be threatened by the Undead innate sense of the living

Here the Ninja selection of their main weapon of attack will be crucial. Traditional favorites such as Shuriken Throwing Stars, Chains, Nun-chukkas flails and such forth would be useless against an enemy that neither needs air or has vital organs to puncture.
Only the Brain and the spinal cord are vital and both are heavily protected.
Because they can only be stopped by destroying the brain or severing the spinal cord a human male has little to no chance of inflicting the sort of damage needed to stop a Type 1 Zombie if he is relying on Kung Fu type attacks alone .
Even the horrific back breaking reversed crab attack is successful in breaking the spine at its base the Zombie will only lose the use of its Legs .
any striking or grappling with it increases the likelihood of contamination.
The obvious Ninja type weapon that might be up to the job is the Straight Sword or Ninja-to with a blade of about 24 inches its perfectly capable of decapitating this enemy.
But only if he find this weakness will the Ninja win
In conclusion

The Winner

Ninja wins 5 to 1
so to make it a fair fight the Ninja needs to face off against at least 5 Zombies
