The Kurgan

His tribe, part of the Kurgan culture, were infamous for their cruelty, known to "toss children into pits full of starved dogs, and watch them fight for [the] meat" for amusement.

During this time, the Kurgan uses his status as a New York City criminal skinhead gang leader as a fake background and goes by the alias "Victor Kruger."

The last six Immortals are Victor, MacLeod, Sunda Kastagir, Iman Fasil, Osta Vasilek, and Yung Dol Kim.

Vasilek is beheaded by the Kurgan in New Jersey before he learns of Fasil's death in Madison Square Garden at the hands of MacLeod.

In order to throw Connor's concentration off, the Kurgan kidnaps his then-girlfriend, Brenda Wyatt, and takes her to the Silvercup Studios building.

Upon returning to life, the Kurgan forced his father to swallow a searing hot stone, killing him.

From the fifth to thirteenth centuries, the Kurgan would spread terror with the Tatars of the Gobi and Turks/Turkish People, as well as with Viking raiders and the Mongol horde of Genghis Khan.

[3] In the final shooting draft of the Highlander II: The Quickening screenplay, it was revealed that the Kurgan was in fact originally sent from the planet Zeist to Earth by General Katana in order to hunt down Connor MacLeod and Ramirez before either of them could win "The Prize" and therefore return to Zeist.

To exemplify the Watchers' knowledge, Dawson showed Duncan his fellow Clansman Connor's, the Kurgan's, and his own personal databases.

In the Watcher Chronicles DVD supplements, it's also mentioned that from 1981 to 1985, the Kurgan was watched by future leader of the Hunters, James Horton.

Highlander: Way of the Sword, published by Dynamite Entertainment, further expands on Kurgan's life and gives him more encounters with Connor.

During the battle, he faced off with a Spartan warrior who wielded a katana made by the master swordsmith Masamune, strong enough to shatter Kurgan's blade.

The ship sank, taking Kurgan to the sea's bottom, where he revived and claimed the Masamune katana as his own.

[7] After these events, Kurgan would return to his native Russia, pillaging alongside the Cossacks near the end of the nineteenth century.

[8] During the First World War, in 1918 Galluzo, Italy, Kurgan hired two gypsy women, Natasha and Stasya, to lure Francesco, an Immortal monk, from holy ground with the promise of sexual favors.

[9] During the 1960s during the Cold War, Kurgan entered into an unholy partnership with the government of the Soviet Union to create a genetically engineered army of mortal super-soldiers purportedly loyal to the U.S.S.R., but in fact created to aid Kurgan in his quest for "The Prize" – men possessing greatly slowed metabolism and aging, as well as superior fighting and swordsmanship abilities.

Kurgan's influence would continue to be felt in the world for some time to come – Connor MacLeod received a "Dark Quickening" from his enemy, resulting in the deaths of several innocent Immortals at Connor's hands in early 1987, until Duncan MacLeod aided in purging Kurgan's last influences from his cousin's tortured psyche.
