Season 1

An Apache - the greatest stealth fighter in American History, versus a Gladiator - crowd-thrilling killer of ancient Rome. It's stone versus steel, devious against direct, surprise versus slaughter, as these two go toe to toe in a no-holds barred battle to the death.

The speed and fighting style of a Samurai warrior faced off with the strength and determination of a Nordic Viking.

Spartan vs Ninja - the ultimate bronze age warrior meets the silent assassin from Japan.

A Pirate - the merciless high seas marauder; versus a Knight - the armored battle tank that crushed infidels underfoot. It's an explosive, bloody battle between two fighters who hate everything the other stands for - pistols versus crossbow, gunpowder against armor, and cutlass versus a spiked ball of death.

Mafia - the deadly crime family that rule New York's 1920's underworld, versus Yakuza - feared gang lords that dominate the mean streets of 1940's Tokyo. Their bloody turf war to decide who is deadliest will be settled with machine guns, sawed off shotguns, pistols, bats, nunchukus and icepicks.

Green Beret - America's elite special force, versus Spetsnaz - Russia's top-secret, top-notch commandos. Trained to kill anyone, any when, anywhere - these super soldiers use a devastating array of weapons and tactics. It's the best of the west against the beast from the east in a post cold war showdown.

One fights for perfection; the other to honor his ancestors. A Shaolin Monk - the ultimate pacifist killing machine from China versus a Maori - fierce, bone-crushing warrior from New Zealand. Steel whips, metal spikes and wickedly versatile hooks versus wood, shark teeth, stingray spines and stone. The hardest weapon on the battlefield is not made of steel.

Both fight for revenge. Both built an army to spill the blood of their enemies. Deadliest Warrior gets personal with a battle between two of the greatest warrior-generals that ever lived. William Wallace - claymore wielding wild man from Scotland versus Shaka Zulu whose ferocity, speed and toughness became legend.

Two groups whose disregard for civilian casualties in the pursuit of their own agendas have made them infamous. IRA - the urban guerrilla from Ireland versus the Taliban mountain fighters from Afghanistan.
