alt title(s): Inverse Ninja Law

"Anyway, fighting off a dozen ninjas is easy. It's when you run into one ninja that you know you're in trouble."
Diana Peacock, Star Harbor Nights

"Wow! Do we really suck, or is this guy really THAT DAMN GOOD!?"
Hertz, Shoot Em Up, right after Smith outperforms his entire army of mooks.

There's strength in numbers, right? WRONG! It's the opposite in fiction, i.e. superior numbers weaken an army immensely, since it makes the other side even more the underdog.

In any martial arts fight, there is only a finite amount of ninjutsu available to each side in a given encounter. As a result, one Ninja is a deadly threat, but an army of them are cannon fodder.

This is also known as The Law of Inverse Ninja Strength: Threat = 1/N, where N = number of Ninjas or other "Elite Adversaries".

The reason for this is simple: Twenty-plus Ninjas are ultimately Mooks and, narratively speaking, will be treated as such. A single Ninja is probably a main character or The Dragon, and as such is more important to the story and more likely to be someone the audience identifies with.

Put another way, there's no Dramatic Tension in seeing a lot of guys beat up one hero or a small group of heroes; if there are many antagonists, then they have to be weak. But a "fair" fight against equal numbers of opponents can seriously test the characters. It's the same reason boxing matches are one-on-one; saying you punched out Mike Tyson wouldn't be impressive if you were one of eight boxers beating on him.

Likewise, there's also anonymity in numbers— particularly if they're wearing masks and/or identical uniforms; and so the audience will consider them expendible, against all logic In contrast, the audience knows the hero, and can identify and sympathize— and wants the hero(es) to win. Therefore, enemies will be handwaved regardless of number.

This can apply to Elite Mooks other than ninjas. Vampires, for example, are particularly susceptible to Conservation Of Ninjutsu, as are werewolves, alien monsters, Special Forces commandos, and Super Powered Robot Meter Maids.

The effects of this trope are more severe on less individualized groups of ninjas; three of essentially the same guy has an adjusted ninjutsu of about 4:1.

Extra points if, when presented with their multiple adversaries, one character notes that, "We barely were able to handle one, how on earth are we going to handle this many?" right before successfully doing just that.

After ninjas, zombies seem most susceptible to this effect. Invariably, at the beginning of a Zombie Apocalypse, when the living still overwhelmingly outnumber the dead, zombiism spreads like wildfire; it is usually depicted as taking only days for 99% of the population to be killed or converted. But after the first wave, zombies become markedly less dangerous. Stories try to play this down or contradict it, but the fact remains: in the first scene, a small number of zombies will wipe out most of humanity. Once the dust has settled, the half-dozen human survivors around whom the story focuses will each personally kill dozens, sometimes hundreds, of zombies, and be picked off only one-by-one. In this case, given the comparative weakness of individual zombies, it may be that normal humans are benefiting from conservation of Ninja.

Examples

NOTE:

Many of these examples seem to confuse this issue, citing "elite forces" which, while fewer in number, are capable of winning by being simply better than the average 1000-mook division. That's not what this trope is about— i.e. NUMBERS = SUCK. In this trope, nothing changes except the numbers;, increased numbers simply cause an enemy to become mooks, because it ratchets up the tenstion... and the increased danger lowers the suspension of disbelief. PERIOD.
