Nikki was introduced with her sister
Casey in 1978. The following year, she killed her abusive father Nick Reed (
Quinn Redeker) in self-defense after he drunkenly tried to
rape her. During the murder trial,
Jill Foster (
Brenda Dickson) hired a Nick look-alike named Joseph Thomas to scare Nikki and Casey. Following the trial, she dated
Paul Williams (
Doug Davidson), but it ended after he gave her a
venereal disease. Nikki would go on to romance
Greg Foster (
Wings Hauser). While Paul opposed the relationship, she ultimately married Greg.
Rose DeVille (
Darlene Conley) signed Nikki to a "modelling agency" which was later revealed to be a
prostitution ring. Nikki resisted a customer, who later had a
heart attack. A man named Tony was charged for the murder, with Greg representing him. Nikki was threatened not to testify in the case or Greg would be killed. She decided to leave town, but returned a little while later. Nikki would later join the New World Commune and Paul would join her. However, they discovered that it was actually a cult, and Nikki would become pregnant after being raped by a cult leader, Ian Ward. Steven Williams and Peggy Brooks worked to expose the cult, and Nikki ended up escaping to Chicago. She gave birth to the child, later to be known as Dylan McAvoy, in a church, but passed out during labor and the nuns took the baby away. Greg, thinking Nikki and Paul had reunited, divorced Nikki. Once Nikki returned to Genoa City, she became a
stripper while romancing Kevin Bancroft (Christopher Holder). Kevin's mother Allison Bancroft (Lynn Wood) hated Nikki, and bought a
pornographic film titled
Hot Hips, purportedly starring Nikki, hoping Kevin would leave her, which he did. A criminal named Tony DiSalvo distributed the film. Nikki married him in hopes of getting her hands on the film rights, and later found out she wasn't even in the film. Paul and his partner
Andy Richards investigated Tony and killed him. While still a stripper, she had a fling with rich business tycoon
Victor Newman (
Eric Braeden), and became pregnant with his child. Initially, however, Nikki believed that the child was Kevin's, but it turned out to be Victor's. She gave birth to
Victoria in 1982 while still married to Kevin. After Tony's death, Victor moved on with
Lorie Brooks (
Jamie Lyn Bauer), while Nikki hooked up with Rick Daros. Unknown to Nikki, Rick killed his first wife and intended on doing the same to Nikki. Once Victor learned of Rick and Victoria's true paternity, he, Paul, and Andy rushed to St. Croix to save Nikki. In a gunfight, Rick escaped while a shot Victor professed his love for Nikki and proposed. Once Victor recovered, he and Nikki married in 1984 despite interference from his ex
Eve Howard. Eve had previously tried to kill Nikki before the wedding ceremony, later running off with Rick Daros. Victor and Nikki's marriage was strong until he had an affair with
Ashley Abbott (
Eileen Davidson), the sister of rival businessman
Jack Abbott (
Terry Lester). At the same time, Jack was attracted to Nikki, and they began an affair. Victor left Nikki for Ashley who ended up pregnant, but secretly had an abortion. Nikki schemed to break up Victor and Ashley by using Matt Miller (Victor's brother) to seduce Ashley, but failed. Nikki was soon diagnosed with a terminal illness bringing Victor back. Once she recovered and lied to Victor about it, Victor returned to Ashley until he learned of her abortion. Nikki ended up giving birth to a son,
Nicholas Newman (
Joshua Morrow), but shortly thereafter Victor divorced Nikki thinking she was involved in Jack's role in a tell-all biography about Victor. Unknown to Victor, the book was actually written by
Leanna Love (
Barbara Crampton). Once Victor learned the truth of Leanna's book, he tried to win back Nikki through a business deal with Jack (now
Peter Bergman). Yet the deal fell through and, out of spite, Jack and Nikki married in 1990 as Victor ended up marrying Ashley. Her marriage to Jack was unsuccessful; his business with
Jabot Cosmetics got in the way of their "friendly" marriage. Following a riding accident where she miscarried a child of hers and Jack's, she sunk into a state of depression, developing addictions to painkillers and being an alcoholic to help her recovery. Victor would eventually return to Nikki's side in her addictions, but Nikki ended up pregnant with Jack's son. After an argument with Victor, Nikki gave birth to a stillborn, John Abbott III, and Jack divorced Nikki, but they remained friends. Nikki was devastated soon after when Victor "died" after finding a burned body inside his car in Kansas, although it turned out he was alive. Victor had been living in Kansas with
Hope Adams (
Signy Coleman). Nikki during this time began a relationship with
Brad Carlton (
Don Diamont) and later got engaged. Victor and Hope came back to Genoa City, much to everyone's amazement. On the night of Nikki and Brad's wedding, Victor was shot by
Mari Jo Mason. She left Brad at the altar and rushed to Victor's side. Victor ended up choosing to return to Hope. While Victor returned to Kansas, Nikki married her doctor
Dr. Joshua Landers (Heath Kizzier). Victor's relationship with Hope ended, and he returned to Genoa City to stop Nikki and Joshua from marrying. However, Victor would go on to get involved with Jack's former lover
Diane Jenkins (Alex Donelley). Jealous of Diane, Nikki convinced Victor to have a vasectomy before she secretly stored his sperm in a bank. Joshua was shot and killed by his presumed dead mentally ill ex-wife,
Veronica (
Candice Daly), who had disguised herself and had been posing as Nikki and Joshua's maid, Sarah Lindsey. Hours later, having been the victim of emotional abuse from Nikki for many months, Veronica shot and severely wounded her employer, leading Victor to
divorce Diane and remarry Nikki on her deathbed. Victor promised Diane that he would remarry her after Nikki died. When Nikki miraculously recovered, Victor decided to be with her instead of Diane. Yet, Victor was still legally married to Diane and their divorce continued into 2000. Diane remained in love with Victor and
stole his sperm to impregnate herself with his child. However, Ashley and Nikki too stole the sperm and a mix-up was created. Ashley became pregnant with Victor's child and Diane with Jack's. Ashley gave birth to
Abby Carlton (Brad was thought to be the father) and Nikki was engaged to Victor by 2002. Their engagement was hindered by Victor's old fiancée
Lorie Brooks and her soon to be ex-husband
Max Hollister schemed to break them up. Max was involved in a bad business deal with Victor regarding
Julia Newman Martin's design firm. In the end, Lorie couldn't follow through, and Victor and Nikki remarried in September. Shortly into Victor and Nikki's remarriage, Nikki was
kidnapped resulting in
post-traumatic stress disorder and was shot by a carjacker. Nikki began having more memories about her childhood and ended up having an affair with
Bobby Marsino, who was the brother of one of Nikki's childhood friends whom she accidentally killed. In 2005, their granddaughter
Cassie (
Camryn Grimes) was killed in a car accident. Then, Nikki developed more of an interest in business. Several years earlier, with Jabot in dire straits, Nikki gave them $35 million to help get the company out of debt. Nikki then became a stockholder at the company and had a seat on the board; much to everyone's dismay. Nikki later sold her stock to start her own company, NVP Retreats (a wellness spa company). In 2007, she ran against ex-husband Jack in the race for
Wisconsin state senate, but after a few mistakes and being caught on tape kissing
her campaign manager, David Chow (
Vincent Irizarry), she lost the election. Victor and Nikki eventually divorced, fueled by her involvement with David Chow. She walked away with a $100-million divorce settlement. After
Katherine Chancellor stepped down as CEO of Jabot, Nikki took over; this caused tension between Nikki and Katherine's "daughter" Jill. Nikki stepped down as CEO of Jabot after hearing that David had killed
Ji Min Kim, Jill's current lover. Regardless, Nikki married
David Chow in June 2008 in Mexico. It was revealed that he was addicted to gambling.
Paul Williams investigated David and found that "David" was not even his real name. Upon learning David was going to drug her, Nikki was going to ask for a divorce. However, David died in a car accident, which also killed Victor's wife
Sabrina Newman. Victor and Nikki's relationship as friends broke down around this time, too, after she tried to console him. After Victor disappeared again, Nikki became determined to find him, however, she ended up getting involved with her early love, private investigator and long time friend Paul, while Victor and Ashley reconnected. By May 2009, Nikki accepted Paul's marriage proposal, but the night before their wedding, she broke things off and left town. She once again returned, and after Victor was shot by
Patty Williams, Nikki left with him after a heart transplant to undergo rehabilitation in a center in Europe. When Victor and Nikki returned in 2010, they were engaged. Meggie McClaine, a friend of Victor, had moved in for her own protection. Meggie sabotaged Nikki, getting her drunk so that she could marry Victor instead of Nikki. Meggie recruited
Deacon Sharpe to help get Nikki off the wagon. Nikki went to rehab. When she learned of Victor and Meggie's marriage (which was just a scam to have Meggie caught) she had an affair with Deacon, ending her relationship with Victor. Nikki continued her romance with Deacon, without knowing the truth. Nikki and Victor slept together after he lost a lawsuit against his children; however, he was involved with
Diane Jenkins at the time. Upon learning the truth about Deacon's role in her drinking, Nikki left him but it was too late for her to return to Victor, who had married Diane. Alone, she began drinking once again. After several attempts at trying to get back together, Victor and Nikki parted ways, and she returned to rehab. Diane was killed months after, and Victor was jailed for her murder. After being missing from rehab for several months, Nikki returned home. She confesses that she escaped rehab to help her family in the aftermath of the Diane Jenkin's murder investigation. Deacon threatened to confess that he saw Victor, Victoria and Nicholas in the park the night of Diane's murder unless Nikki would marry him; she agreed. Nikki began having memory lapses of her night in the park with Diane; realizing that she had killed her, not Victor. She confessed to this at Victor's trial. Detective
Ronan Malloy arrested Nikki for the murder; however, footage from the night, shot by Deacon, revealed that while Nikki did kill Diane at the park, it was in self-defense. Additional footage showed that Deacon finished her off, serving the last fatal blow to Diane's head. Deacon was jailed and his marriage to Nikki ended. Nikki's brief relationship with Victor failed; she began to reconnect with Jack who was suffering from a gunshot wound from
Patty Williams that had left him paralyzed. Their relationship heated up, much to the dismay of Kyle, yet he came to accept the relationship, and Nikki and Jack remarried. Yet, the day of her marriage, Victor remarried
Sharon Newman, but then went suddenly missing. Nikki ended up leaving Genoa City to try to find Victor, but to no avail. When she returned, Jack decided they should divorce. Victor later returned, having lived in Los Angeles with amnesia. He reunited with Nikki and set out to destroy Sharon and
Tucker McCall who took control of Newman during his absence. After Victor lost control of Newman to Jack through a hostile takeover, Victor suffered a heart attack, and later Sharon burned down the Newman Ranch during a mental breakdown. Once Victor escaped the hospital to visit the ruins, he and Nikki finally got engaged. However, their wedding was delayed because Nikki was diagnosed with
multiple sclerosis. Victor and Nikki finally remarried on March 20, 2013, in a ceremony that ended with
Adam Newman (
Michael Muhney) taking an assassin's bullet meant for Victor. Adam survived, and he and Victor began to rebuild their relationship. Nikki continued with her MS treatments, and held fundraisers for research. Katherine Chancellor died in August after a three-month vacation around the world. Katherine left Nikki and Jill in charge of her memorial service, and left Nikki a letter encouraging her to look into the child she had following her stay at the New World Commune. The child is later revealed to be
Dylan McAvoy (
Steve Burton), the son of Nikki and Paul. ==Reception==
