The first-born son of legendary supercouple Luke and Laura Spencer, Lucky is a reflection of his parents, with his mother's practicality and his father's sense of adventure. His similarities to his parents have sometimes led to some friction, mostly between his him and his father whom he both admires and abhors. His relationship with his mother has usually been loving and stable. However, his relationship with both his parents hit a major roadblock when he found out that he had a half-brother, Nikolas Cassadine.

In the beginning, Lucky and Nikolas' relationship could best be described as rocky. The brothers were caught in the midst of the bitter Spencer and Cassadine feud. But the brothers soon learned that they didn't hate each other at all. With the battle between their families seemingly neverending, Lucky and Nikolas made a pact to stay out of the feud.

Lucky's compassionate nature led him to become a pillar of support for troubled Elizabeth Webber after she was raped after their high school's Valentine's Day dance. Around the same time, Lucky learned that Laura had been raped by Luke before they fell in love. Horrified, Lucky didn't want to have anything to do with his father. Lucky could only confide in Elizabeth about his family problems, and the bond between them became stronger. Eventually Lucky left home and prior to getting his own place, stayed with Elizabeth. After some time, Lucky reconciled with his parents.

As their high school days were coming to an end, Lucky and Elizabeth prepared for a future together, planning to move to New York City where Elizabeth could go to art school. Lucky surprised Elizabeth with a dress and another surprise, as he took Elizabeth too a romantic chapel where they vowed to love each other forever.

However, fate, in the form of Helena Cassadine and Cesar Faison, would interfere. Staging a fire in Lucky's apartment, Helena whisked the young man off to a remote cabin where she kept him captive. Those in Port Charles believed Lucky had died, leaving behind a devastated family and his young love Elizabeth. For the next year, Lucky was held captive in elaborate locations while becoming adept at chess.

When Luke found evidence that Lucky was alive, he set out to find him. Around this time, Helena took Lucky to the Triple L Diner and let him go, where Luke and Laura found him. However, their son had changed. Lucky didn't want anything to do with his parents and blamed them for what he went through. Lucky eventually returned to Port Charles and his attitude and behavior puzzled Elizabeth, Emily and Nikolas. Things became even odder when Lucky began trying to push Elizabeth and Nikolas together.

Attempting to get through to Lucky, Elizabeth surprised Lucky at the boxcar and they shared a kiss, but Lucky pulled away and claimed that everything they shared in the past was gone. Elizabeth and Emily decided to recreate the last Four Musketeers dinner they had the night of the fire. The quartet met at Kelly's and the night seemed successful at first, but then suddenly, Lucky began pushing Elizabeth, Nikolas and Emily away and stormed out.

Another blackmailing attempt on Emily reunited the Four Musketeers, both physically and mentally, as Lucky and Elizabeth were able to reconnect more. However, Lucky still kept pushing Elizabeth away. Soon, Lucky began to realize something was wrong with him. Elizabeth stumbled upon Helena using a trigger phrase to control Lucky and realized that Helena had brainwashed Lucky. Elizabeth used Helena's trigger phrase on Lucky, who realized that he had been brainwashed. Soon, Lucky began to seek treatment under Dr. Kevin Collins, to help him get out from Helena's control.

Helena, though, was still controlling Lucky. She used the Ice Princess Diamond to brainwash Lucky into killing Jason Morgan, Emily's brother.  Lucky attacked Jason, but couldn't remember doing it or why. To make matters worse, Helena gave Lucky a diamond ring to give to Elizabeth to propose to her.

Lucky continued to get into trouble due to Helena's mind control. He attacked Nikolas in the hospital when his brother told him he needed to get more help from Kevin Collins. Stefan intercepted to protect Nikolas and had Lucky arrested. Luke and Laura realized Lucky needed help asked Dr. Collins to go to jail and try to deprogram Lucky. Unfortunately it was unsuccessful when Helena showed up and convinced him to escape. When Elizabeth found him, she told Lucky he needed to get help again. But he continued to follow Helena's orders and even poisoned Lucas' drink.

Lucky and Elizabeth moved into Nikolas and Gia's house so they all could keep an eye on Lucky. He learned he had a passion for photography and Carly hired him to take pictures of Gia who had become a model.

Helena told Lucky about a lab underneath General Hospital where Lucky found Luke and Stavros fighting. Helena told Lucky to stab his father with a syringe full of a virus that would make Luke go crazy. Afterwards Lucky broke off his engagement with Elizabeth because he realized he could not control himself. He told her she should be with Nikolas.

Lucky was kidnapped again by Helena's goons, or so he thought. But it was actually Elizabeth who was responsible. Lucky then realized how much she loved him and they agreed to be together. While Elizabeth hid out on a closet and watched, Helena used the Ice Princess again to erase all of Lucky's memories of his love for Elizabeth. But Helena soon learned that her plan did not work when she tried to show everyone her secret weapon in her plan to take over the world, Lucky. Instead of complying with her wishes, Lucky rejected her and she realized his programming was not working because he had been focusing on his love for Elizabeth. Helena was then arrested.

Thinking he was free from Helena's mind-control, Lucky and Elizabeth reunited. However, the damage Helena had done proved to be too much for the young couple to overcome. Helena had managed to brainwash Lucky into forgetting his love for Elizabeth. The pair tried, but could not recapture their love. Elizabeth's newly returned sister Sarah caught Lucky's eye and they began an affair. In the midst of this, Elizabeth and Gia were involved in a car accident. Nikolas tried to hide the fact that Gia was at fault, but Lucky found out. But instead of telling Elizabeth, he kept it from her. However, Elizabeth found out and she severed her friendship with Nikolas and Gia and broke up with Lucky.

Meanwhile, Maxie Jones had developed a crush on Lucky. He tried to let her down gently, but she was devastated. To back at Lucky for hurting her, Maxie told Elizabeth she had seen Lucky and Sarah go to his room. Elizabeth found them and felt shocked and betrayed, splintering further her relationship with Lucky. Sarah and Lucky's relationship did not last and Sarah left town.

When Luke and Laura didn't show up to their own wedding, a worried Lucky and Nikolas went to look for them and found Laura's stepfather Rick Webber dead in the attic. To protect Luke, the brothers staged a drunk-driving accident, putting Rick's body into their car and pushing it over a cliff. Meanwhile, Laura suffered a mental breakdown and was sent to a mental institution in London.

Luke was arrested for Rick's murder and disappeared. Elizabeth and Lucky went in search of him and found him working on a chain gang. The pair brought a distraught Luke back to Port Charles. Luke felt responsible for driving Laura over the edge and tried to punish himself. Lucky tried to get through to his father and was able to help him realize that the secret Laura had been harboring was what drove her mad.

Lucky soon enrolled in college where he met a woman named Summer, who was going by the name Laura in school. They soon became good friends as Laura confided that she was a former call girl and had been abused by one of her clients. Lucky and Summer's friendship soon developed into romance, however, Lucky was shocked to learn that Summer was also the new woman in Luke's life. Luke liked her because she reminded him of his "angel" Laura and their friendship was helping him deal with Laura's condition. Lucky and Summer decided to keep their relationship a secret from Luke, but he found out and fully wanted his son and Summer to be together. Neither Luke nor Lucky knew that Nikolas had actually hired Summer to distract Luke from Laura.

Luke and Lucky's relationship suffered another crack when Luke blamed Lucky for the fact that Nikolas had control over Laura's treatment. At Nikolas and Gia's engagement party, tragedy struck. Summer was pushed over the bluffs and died. In his grief, Lucky initially blamed Luke for Summer's death. Eventually Lucky began to suspect that someone else was responsible for Summer's death. Lucky badgered Mac to look into it. Mac responded by challenging Lucky to become a cop himself and investigate. Lucky took Mac up on his challenge and enrolled in the police academy. All the while, Lucky and Nikolas were working to prove their theory that Nikolas' uncle Stefan had actually orchestrated Summer's death, mistaking her for Emily who had been wearing similar clothing.

Luke returned to town and when he found out Lucky had become a cop, he panicked. His thirst for revenge unquenchable, Luke kidnapped Stefan and conducted a mock trial for Stefan and broadcast it to across town. Lucky was forced to arrest his father after Stefan was murdered. However, Stefan had not really died, but had framed Luke for his murder. When the truth came out, Luke was exonerated.

Lucky continued his work with the Port Charles Police Department. However, his life changed when his brother Nikolas was presumed dead after a car accident. Lucky supported Nikolas' girlfriend and fellow Musketeer Emily cope with the loss of Nikolas, but soon found himself developing feelings for his friend. Discovering Nikolas was alive, Emily attempted to make him fall in love with her again. Complicating matters, however, was the fact that Nikolas believed himself to be a happily married Connor Bishop. Nikolas eventually regained his memory and returned to Emily and the Four Musketeers were again reunited. However, Connor's widow Mary, who had fallen for Nikolas, went crazy and attempted to kill Emily. She ended up killing Lorenzo Alcazar's niece Sage. Nikolas eventually was forced to shoot her to save Emily and she later died at General Hospital.

Nikolas and Emily got engaged, infuriating his psycho grandmother Helena. She placed a curse on them and tried to stop the wedding with the help of Tracy Quartermaine. In a struggle, Nikolas killed Helena. But there was a witness - the real Connor Bishop. Connor had returned to PortCharles to reunite with his wife, but found she had died because of Nikolas and Emily. Connor began to stalk Emily and attempted to blackmail Nikolas with his knowledge of Helena's murder, but Nikolas turned himself in and was sent to prison. Lucky and Elizabeth attempted to help Nikolas and Emily survive this ordeal. While helping with Nikolas and Emily's wedding, Elizabeth admitted to Emily that she still had feelings for Lucky, who had meanwhile, been falling back in love with Elizabeth. The pair began to reconnect at Nikolas and Emily's wedding where they were Best Man and Maid of Honor, respectively. But both decided to take it slow.

Lucky and Elizabeth continued to help Emily with trying to get Nikolas out of prison. The trio tried to swap a newly returned, and seemingly contrite Connor for Nikolas. However, the plan didn't work. Having happened upon information that Helena might actually be alive, Luke came up with a plan to flush Helena out, using Connor and Emily as bait, with Connor pretending to be Nikolas. A wary Nikolas reluctantly agreed to the plan so long as Lucky and Elizabeth were there to help out.

When the plan went wrong, Emily was rushed off to a safe house with Connor. One night, after Lucky and Elizabeth had left, Connor got drunk and raped Emily. Emily stabbed him with garden shears and when he tried to attack her again, she shot him. Lucky and Elizabeth arrived to find Connor dead. Lucky buried Connor while Elizabeth dealt with a very distraught Emily. Elizabeth suspected Connor raped Emily, but Emily was in complete denial. Helena managed to kidnap Emily, locking her in the Cassadine crypt. Lucky was able to find her, but was shot by Helena when he attempted to rescue Emily. Lucky was rushed to the hospital in a coma. Elizabeth stayed at Lucky's bedside as he slipped further and further into a coma. Luke had a difficult time seeing his son in a coma and took it upon himself to pull the plug. Fortunately, Skye showed up in time to turn the machines back on. A legal battle ensued and Luke was forced to stay away from Lucky. Luke snuck back in and pulled the plug again. This time when Skye showed up, Lucky was breathing on his own.

After a near-death experience in which Elizabeth was the only one to keep him front "walking to the light," Lucky woke up from his coma and started his recovery. Lucky told Elizabeth that he figured out Emily was raped. Lucky agreed to stay at Wyndemere with Emily during his recovery. Both he and Elizabeth thought it would be good for him to be there so he could help Emily deal with her traumas. Lucky and Elizabeth were worried about Emily and continued to rally her to not give up on Nikolas. They were shocked to discover Emily's divorce papers. When they confronted her with them, Emily told them her marriage was over.

Confused by Emily's recent behavior, Nikolas asked to see Elizabeth. A jittery Elizabeth went to see Nikolas in prison. Putting two and two together, Nikolas deduced from Emily's behavior and Elizabeth's demeanor that Connor had raped Emily, Nikolas was devastated but vowed to himself to help his wife. When Emily told Nikolas she wanted a divorce, he revealed he knew what had happened. Emily assumed Elizabeth had betrayed her trust and lashed out at her. Elizabeth assured her she didn't reveal her secret and that Nikolas probably figured it out on his own.

Helena was eventually captured and Nikolas was released from prison. Lucky and Elizabeth tried to help them as much as they could, but Nikolas and Emily were at an impasse. Elizabeth really felt therapy would help Emily deal with the rape. Elizabeth explained that when she confronted her rapist, she really started healing. She suggested Emily do the same thing. Since Connor was dead, Nikolas volunteered. Nikolas didn't feel the session went well, but Emily felt she was really making progress.

As Nikolas and Emily continued to work through their problems, good things were starting to happen for Lucky and Elizabeth. Lucky was officially reinstated to PCPD, and asked Elizabeth and Baby Cam to move in with him. Things were going well for them until the reality of bills started to hit them. Lucky had a lot of medical bills from the shooting and they were in dire need of money. While working her shift at General Hospital, Elizabeth heard from Dr. Meadows about Jax and Courtney's need for a gestational host. Elizabeth paid Jax a visit and offered herself as the host. But after to talking to Lucky, Elizabeth decided against it. However, Elizabeth was moved by Jax and Courtney's plight, and eventually agreed.

The decision brought Jax into Lucky and Elizabeth's life as a prominent figure. Lucky became very jealous as Jax continued to insinuate himself into their lives by fawning over Elizabeth and buying extravagant gifts for Cameron. Lucky became very angry and him and Elizabeth tried to deal with the issues they were having as a result of the surrogacy, but things were about to boil over. Lucky and Elizabeth attended Carly's fundraiser with Nikolas and Emily. Lucky saw Jax's monetary donation to GH as his way of flaunting his money and power. Lucky didn't want to be there and left. He quickly returned to the party and told everyone the roads were closed due to the coming hurricane.

As the hurricane approached, the house had to be secured. Nikolas and Lucky were taping up the windows when Jax and Lucky got into another fight about the surrogacy. Lucky punched Jax. Jax refused to fight back and even offered to cancel the arrangement. Elizabeth considered the offer but wondered if she was already pregnant. She made it clear that if she was pregnant, she would not abort the child. Lucky admitted to Elizabeth that his pride got in the way again and he was sorry. Lucky proposed to Elizabeth who happily accepted.

Soon after Courtney arrived, Lucky and Elizabeth announced their engagement. Courtney sensed immediately that Jax wasn't happy. Jax admitted that the impending marriage would cause problems with the legality of the surrogacy. Jax approached Elizabeth and suggested they postpone the wedding till after the baby was born. When Elizabeth suggested postponing the wedding due to Jax's worries, Lucky got upset and rescinded his proposal. Elizabeth turned around and proposed to Lucky. Lucky saved Elizabeth from a tree that crashed through the window. After Lucky accepted Elizabeth's proposal, Elizabeth was hit with a dizzy spell.

Elizabeth found out she was pregnant. Elizabeth and Lucky decided they should get married immediately. They were at the courthouse when Jax interrupted the ceremony. Lucky agreed to postpone the wedding, but later, he and Elizabeth exchanged vows in the park. He believed they were married in their hearts.

Meanwhile on the workfront, Maxie had convinced her father Mac to let Lucky investigated a suspected dirty cop named Byron Murphy. Both Jesse and Lucky were surprised when Murphy showed up at the docks, ready to kill them both. Maxie showed up as a fight ensued. Lucky ended up shooting Murphy. Murphy tried to shoot Lucky but Jesse saved him. Mac wasn't happy with this so he made Lucky and Jesse partners. He wanted Lucky to help Jesse take down the drug operation in town and to keep Jesse away from Maxie.

Courtney and Jax were planning the nursery set up when Elizabeth stopped by. Elizabeth started giving her opinion so Courtney split. Elizabeth received a call about Lucky's shooting and fainted. When Lucky arrived to pick Elizabeth up, Jax and Lucky got into a fight over his job and how it would affect Elizabeth. Elizabeth defended Lucky but later admitted to Lucky that she worried about his job.

In the meantime, Emily's brother AJ was murdered at General Hospital. Evidence originally pointed to AJ's biological son (and Emily's god-son) Michael, but soon other evidence soon came to light that challenged Michael's guilt. FBI Agent Reese Marshall, working to exonerate Michael, found out from Dr. Rachel Adair that Michael, in fact, had not killed AJ. It was actually Dr. Asher Thomas who smothered AJ. However, when they went to question Rachel about the claim, Lucky and Jesse found Rachel dead in her apartment, an apparent suicide. Although suspicious, there was no evidence of foul play.

Lucky and Jesse went to question Dr. Thomas. Afterwards, they had to deal with DA John Durant's demand for them to fabricate evidence. Lucky attacked Durant when he claimed that maybe Lucky was a dirty cop on Sonny's payroll. Jesse pulled Lucky off Durant. Irritated, Lucky headed home.

Arriving home, Lucky was surprised to see Jax with Elizabeth in what appeared to be a compromising situation. Jax made his exit as Lucky announced that he thought it would be best if he moved out until the baby was born because he was causing Elizabeth too much stress. Elizabeth was beside herself and fell asleep upset. She had forgotten to extinguish the candles she had set for her romantic dinner with Lucky. She woke up to an apartment full of smoke. The smoke overwhelmed her but she was able to grab Cameron and got out safely. Jax took her to General Hospital to make sure she was okay.

When Lucky, Nikolas, and Courtney heard about the fire, they rushed over to the hospital where Jax and Lucky continued to butt heads.

Jax and Courtney opened their home to Elizabeth and Cameron. Elizabeth and Courtney had a very honest discussion about the baby. Elizabeth told Lucky that she was living with Jax and Courtney until the baby was born. Elizabeth had a nightmare about giving up the baby but covered with Jax and Courtney. She decided she needed some ice cream and went over to Kelly's. She ran into Lucky and decided to hang out in his apartment upstairs. They talked about their future together as they fell asleep.

Elizabeth woke up and realized she never called Jax & Courtney to let them know where she was. Lucky took her back to Jax and Courtney's place where Jax made it clear how upset he was with Liz. Lucky stood up for his woman. Courtney sided with Lucky and Elizabeth as well, causing a huge argument.

Meanwhile, the troubles in fellow Musketeers Emily and Nikolas' marriage were about to explode and Lucky and Elizabeth were about to get caught in the middle. Elizabeth stumbled upon Nikolas and Courtney sharing a kiss on the docks. Soon after, Nikolas told Lucky about the almost affair he had with Courtney. Lucky told Nikolas to stop this and go back to his wife.

Jax presented Lucky and Elizabeth their newly repaired apartment before heading down to join Courtney in the Bahamas. While at work, Elizabeth told Monica about the kiss she witnessed between Nikolas and Courtney. Monica told Emily which led Emily to find out what was really going on. Jax and Emily discovered Nikolas and Courtney in a compromising position. Both Jax and Emily left the Bahamas determined to end their marriages.

After the situation in the Bahamas between Courtney, Nikolas, Emily & Jax, Jax fought with Lucky and Elizabeth over his intentions to divorce Courtney and raise the child on his own. Lucky reminded Elizabeth that if they were to get married before the child was born, Lucky would be the baby's legal father. Jax attempted to bribe Elizabeth into giving him custody of the child in exchange for paying for all of Cameron's future educational costs. Annoyed, Elizabeth turned him down.

Lucky and Elizabeth set up an intervention of sorts for Nikolas, Emily, Courtney and Jax, but Elizabeth developed cramps. All rushed to the hospital where it appeared people were trying to make their respective relationships better. But things weren't going well at all. Lucky told Elizabeth what he believed Jax was up to (using Courtney to get to the unborn child). Elizabeth told Courtney Lucky's suspicions but Courtney believed Jax was being completely sincere.

However, Courtney soon discovered that Lucky's claim was true and Courtney ran off to be with Nikolas. Lucky and Elizabeth tried to be there for Emily as her marriage to Nikolas imploded. Meanwhile, Courtney and Jax bitterly fought and fought. Lucky and Elizabeth were caught in the middle, but became increasingly incensed with Jax's behavior and the situation.

Elizabeth and Jax eventually agreed to an acceptable custody agreement. All seemed well. However, one night while Jax was driving Elizabeth home, they were involved in a car accident when Jax swerved to avoid hitting an unstable Carly. Elizabeth and Jax were treated at the hospital and released. Not long after, Elizabeth developed cramps and was rushed back to the hospital where Dr. Meadows revealed that Elizabeth had miscarried the baby. Devastated, Elizabeth retreated into herself. Both Lucky and Jax worked to raise her spirits. Elizabeth began to heal and Lucky and Elizabeth began plans for their wedding.

Meanwhile, even though they were divorcing, Emily and Nikolas worked together to plan the wedding of Lucky and Elizabeth's dreams. The night before their wedding, Lucky had a fight with his father and uninvited him to the wedding. Elizabeth comforted Lucky and then went separately home - Lucky to Kelly's and Elizabeth to their apartment. On the day of the wedding, everything seemed to be going wrong. Lucky's suit ripped and Elizabeth's dress didn't fit. Then Nikolas and Emily surprised Lucky and Elizabeth with a fully-planned wedding fit for a prince and princess. Before the wedding, Luke, whom Nikolas had a paid a visit to earlier, and Lucky had a father-and-son moment. Luke joined the other guests and the wedding began as Lulu and Emily marched down the aisle ahead of Elizabeth. Lucky and Elizabeth said their vows in front of their friends at Wyndemere. Nikolas and Emily then surprised them with details of their honeymoon which would start with a night at the Metro Court and then a train ride to New York City where they would spend the rest of their honeymoon.

The next morning, Lucky and Elizabeth boarded the train to New York City. They were joined by Nikolas and Emily, along with Jax and a pregnant Courtney. Lucky and Elizabeth were easily the happiest people on the train. Also on the train were Sonny, Reese, Alexis and Ric. Unbeknownst to them, mobster Manny Ruiz had a devastating plan - he had rigged it so that the 6:00pm train from Port Charles would collide with another train coming in from New York, a train on which Robin, Sam, Max and Carly were on. The trains crashed in the Glencove tunnel, trapping the passengers inside. Elizabeth discovered that Lucky had been seriously injured. Lucky woke and said his goodbyes to Elizabeth. Devastated, Elizabeth willed him to live. As Lucky had a heart-stopping moment, the tunnel began to cave in, covering the passengers...
