Alex Udinov

Alex is the daughter of the late Russian oligarch Nikolai Udinov and his wife who were murdered by Division, on orders of Sergei Semak, when Alex was a child. Udinov owned the billion-dollar company Zetrov, of which Alex was the sole heir. Alex was to inherit the Zetrov company, which flashbacks show her as never really wanting in the first place. She was saved by Nikita, after Nikita killed her father, as she watched the rest of her family perish in a fire. Nikita was powerless to save Alex from anything else as she had to return to Division, and she gave Alex to one of Udinov's associates for safe-keeping. Instead, Alex was sold into sex slavery by her father's associate since he needed money and thought no one would recognize her if he did.

To keep her from fighting against them, the slavers kept Alex high and eventually forced her to become a drug addict.[1][2] She escaped the slavers by herself, though she remained a user and was shown in flashbacks to be living as a junkie, living from hit to hit. Alex brings this part of her past up to Amanda, saying that the slavers "had the decency to keep [her] high" as they held her captive, comparing this to Division.

After Nikita escapes Division, she finds Alex again and rescues her before she is about to get raped and forces her to get clean, much to Alex's irritation. It is revealed in a flashback that it was Alex's idea to infiltrate Division, and that if Alex hadn't tried to kill herself in front of Nikita, Nikita would never have told Alex the truth about Division. After Nikita succeeds in helping Alex past the worst part of her withdrawal, she starts to train her both mentally and physically to stay one step ahead of Division once she is inserted there. Nikita makes it clear to Alex that once she gets in, she will be on her own and Nikita won't be able to be there if something goes wrong.

Alex also suffers panic attacks when certain things trigger somewhat suppressed memories of her past, such as being under a car (reminds her of being under a bed as she watched her family die). Alex was shown to also have nightmares about her deceased family, often speaking Russian and screaming for her father. Amanda and Nikita also don't allow Alex to drink alcohol, because if she were she would go back to doing drugs.

At the beginning of season one, Alex was arrested while robbing a drug store with her abusive boyfriend Ronnie; Ronnie shoots the store owner and runs away as the police arrive, leaving Alex, covered in blood, with the stolen drugs. Alex was blamed for the murder and sent to prison – soon after; Alex wakes up in Division, officially having committed suicide in prison, and meets with Michael, who brings her into Division as a new recruit.

This was revealed as a ploy set by Nikita who was actually portraying Ronnie in the robbery, so Alex could get into Division as a mole. Amanda originally thinks that Alex is Ukrainian, yet Alex is originally from Russia. As the season went on, more was revealed of Alex and her relationship with Nikita. Saving Alex was the first time Nikita defied her orders from Division, which were to kill her entire family. As a result, Nikita and Alex share a very close bond that is always being tested. Amanda and Percy both think Alex reminds them of Nikita.

Alex was working with Division to gather the intel and resources she needed to reclaim her birthright. She claimed that she was merely using Division (although Amanda would argue otherwise), she had gone on a number of missions for them, although only if they provided vital information on Semak. Percy only agreed to feed information to Amanda if Alex was the one sent to talk to him. In the first half of season two, Amanda and Alex's relationship took an interesting turn. Although they agreed to be "business partners", it ran a lot deeper than that. Since Alex was away from Nikita, given that she was in Division and Nikita wasn't, Alex turned to Amanda for council. Alex disobeyed Amanda by assassinating Anton Kochenko, they tried to make Alex abort the mission after Nikita messed up their plans. Alex said, "So, Nikita wins again," and then fired her sniper rifle, killing Kochenko. When Alex returned, Amanda was disappointed and angry that Alex disobeyed a direct order. However, unlike any other recruit who would have been punished severely, she went unpunished. Alex, through a series of events, was also being manipulated by Percy. At one point, through blackmail, Percy seemed to have his claws around Alex. Where Alex was once a mole for Nikita, she appeared to be becoming one for Percy instead, though unknowingly.

Eventually she managed to reconcile with Nikita and was able to betray Amanda and Ari. She inevitably retook her father's empire and rescued her mother. For the rest of season two she worked with Nikita in bringing down Division. She later assisted Nikita in her raid on Division, which ended successfully with the deaths of Percy and Roan, and with Ryan Fletcher placed by the US government to be Division's Director.

Alex reprises her alter ego, the spoiled Russian princess Alexandra Udinov, in a unique way for a couple episodes this season. Liza's abduction brings up painful old memories for Alex, who tries to get closer from Liza's mother. Nikita, Michael and Sean attempt to stop a terrorist attack but are one man down after Alex is shot. She saves Nikita by taking a bullet to the shoulder, Nikita goes to kill Mia for revenge. In season 3 episode 4, Alex starts to unravel. It appears Alex is starting to relapse into drugs; however, it is just taking pain pills. She takes them after a heated argument with Sean in the medical facility, and because her bullet wound was causing her so much pain, she gave in and took one pill. After Alex gets sick of waiting at Division and hurt after her and Sean's conversation, she tells Nikita she's going on the mission to Amanda's house with her. Nikita allows her reluctantly, which results in Alex taking a heavy beating from a man twice her size and leaving her in immense pain.

When she gets back to Division she secretly takes more pills, and it appears she is slowly starting to get addicted to them. However, her apparent addiction was not full blown, she would only take them when her arm was in pain. Michael eventually confronted her in season 3 episode 7, and she told Nikita the truth.

Nikita was disappointed and mad at Alex, however, later she told Alex that they would handle her addiction together. When Alex was addicted to drugs, Amanda told her that she becomes anger, and tells her she can use it to her advantage ( Alex usually vents by boxing a punching bag very intensely).

In episode 10, Ryan allows Alex to go back out into the field. Sean becomes jealous of Alex's relationship with Owen. She tells things about her past to Owen that she can't tell to Sean because Sean grew up in a regular American family, and she is afraid of him judging her or not understanding her. Amanda holds Alex hostage and tells Nikita she will release Alex in exchange for Ari. Amanda "brainwashes" Alex with "the chair" by forming bridges where they aren't supposed to. Such as Alex's sex slave past is linked with Division and their current predicament, Alex is still Alex and has good intentions, but she is irrational and mentally unstable.

However, as far as Alex knows she is still herself and everything she is doing is because she wants to. Alex recruits Birkoff to dig up secrets on Danforth to use as leverage in case things get messy with the government. They are shocked when they find out the president has made a kill house and was ready to wipe out all of Division with the marines that were trained. Alex and Sean are tasked with investigating who, inside Division, is behind a mutiny that ends in bloodshed. It is revealed Alex is, but only the mutineers and Ryan knows. Ryan is in a coma because Alex shot him, not with evil intentions though. Alex confesses her desire to leave Division to Birkhoff and almost gets him aboard until Sean interrupts them.
