Nikolai (xXx)

"Looks like little white mouse. (laughs evilly) Bye bye, little mouse!"

- Yorgi betraying Nikolai and his men.

Nikolai is a minor antagonist of the 2002 action-thriller film xXx. He is a rogue Russian scientist who was in league with Yorgi of Anarchy 99 until the events of the film.

He was portrayed by Vitezslav Bouchner.

Allying with Anarchy 99
Being a well-known chemist of Mother Russia, Nikolai was known for stealing a biochemical weapon called Silent Night and was brought over by Yorgi, who plans to use it on creating worldwide anarchy. To that end, Yorgi gave Nikolai and his team of scientists and technicians their own laboratory under Yorgi's mansion to oversee their experiments on Silent Night.

As part of the assignment given by Yorgi, Nikolai gets his men to create missiles that will deploy Silent Night throughout the vicinity on any city that it hits, which will result the deaths of millions of citizens. Nikolai also arranged the creation of a giant water drone (which they dubbed Ahab) that will deploy the missiles around the world.

Betrayal and Death
Upon the completion of Ahab and the missiles, Nikolai reports of his success to Yorgi, who happily thanks him and his team for a job well done while showing Yelena, Kirill, Kolya and Viktor of the progress. As Nikolai and his team drink a toast, little did they know that Yorgi and his men have sealed off the lab before setting one of the missile to launch, believing that Nikolai and his men have outlived their purpose. Upon seeing this and realizing that he has been used, Nikolai and his men begged for mercy while banging on the lab door just as Yorgi sadistically launches the missile into the lab's ceiling, spreading the gas and killing Nikolai and his men.

This event is what brought Yelena (who turns out to be a undercover Russian agent) in tears, even the arriving Xander Cage is horrified by this turn of events after realizing Yorgi's true plans.
