Introduced in 1993 as Lucas Roberts, the military-cadet son of business-woman, Kate Roberts, he later discovers he is the son of Bill Horton. Lucas is known for his many romantic liaisons, particularly with Sami Brady, a relationship his mother strongly disapproves of and repeatedly tries to derail. In 2007, fed up with his mother's interfering, Lucas changes his and his son's surname to his father's. With Sami Brady, Lucas is the father of Will Horton and Allie Horton. He has recently been romancing his latest ex-wife, Chloe Lane. An important storyline for the character is a recurring battle with alcoholism.


Lucas comes to Salem with his mother, Kate Roberts after returning from military school. He quickly befriends Sami Brady and the two start scheming to break up her sister, Carrie Brady and her boyfriend Austin Reed, because Sami wants to be with Austin and Lucas wants to be with Carrie. Lucas tells Sami that losing weight may get Austin's attention leading to her going on a crash diet. Lucas also convinces Carrie to get plastic surgery to help her get a modeling gig as Bella's Face of the 1990s. Lucas is shocked to learn that he is the illegitimate son of Dr. Bill Horton and that Austin and his sister Billie Reed are his maternal half-siblings.

When Lucas' friend from school Alan comes to town, he rapes Sami and takes Carrie and Sami hostage. Alan is sent to jail, but Sami fears that nobody will ever love her. Lucas is feeling rejected by Carrie. Lucas and Sami find comfort in each other and have sex. Soon after, Sami drugs Austin and tricks him into sleeping with her too by pretending to be Carrie. Carrie learns that Austin has slept with someone else, but she doesn't know it was her own sister. Austin and Carrie were apart because they both suspected the other of being unfaithful.

After Lucas' mother Kate is apparently killed in a plane crash, he learns that Vivian Alamain has something to do with it and he blackmails her into finding Sami and bringing her home in time to stop Austin and Carrie's wedding. Sami returns, claiming she is pregnant with Austin's child. What Lucas doesn't yet realize is that he is baby Will's true father.

Sami's plots continue and eventually bring Carrie and Lucas together, freeing up Austin for Sami. Eventually, Lucas's mom Kate (who survived the crash, and is back in town) learns the truth and exposes both Lucas and Sami. Carrie and Austin are reunited. However, an accident leaves Sami with amnesia, which Lucas uses to his advantage. He pushes Sami towards Austin, to keep him away from Carrie. Even as Sami's memories starts to return, Lucas convinces Sami to help him with a new plot to convince Austin that Carrie is falling in love with Mike Horton. Lucas thought that once Austin gave up on Carrie, he could easily steal her from Mike. Once Austin is free, Sami plans to steal him from Carrie.

As usual, the truth eventually comes out, and Austin and Carrie marry. Lucas learns that Sami has been blackmailing his mother, but Kate refuses to tell him what Sami has on her. After Sami becomes engaged to Franco Kelly, Lucas refuses to let Franco become Will's stepfather. Kate leans on Franco, but he attacks her. Lucas walks in as Franco is about to smash a poker over Kate's head, and he shoots Franco to save Kate's life. Kate frames Sami with the killing, so Lucas can get custody of Will. Sami is almost executed. At the last possible moment Lucas confesses, but the execution is actually stopped because Kate has gotten a dying man to sign a false confession, and Sami is saved.

Lucas later falls in love with Nicole Walker, but she is in love with Eric Brady, Sami's twin brother. Unbeknownst to Lucas, Kate pays Nicole five million dollars in 1999 to marry Lucas so that he can win custody of Will. The plan works, but after Sami is released from prison, she works with Nicole to get Will back. Nicole gets Lucas drunk and seduces him and makes him think he has beaten her and he confesses to killing Franco. They are divorced less than a year after being married.

After being injured in a fire purposely lit by his mother in the Kiriakis Mansion, Lucas is sent away to a rehab center due to his alcohol addiction.

Lucas comes out of his coma a year later and returns to town, but he is still partially paralyzed. Lucas seems to really want to make amends, but shows his true colors at Austin and Sami's wedding when he exposes the truth and ruins the wedding. Eventually, with Victor's help, Lucas gets joint custody of Will. Lucas takes Will for a summer holiday in Africa.

Upon their return, Lucas goes from being strongly on Victor Kiriakis 's side to working for his nemesis, Tony DiMera. He enjoys his new power, but the stress drives him back to drinking. His AA sponsor and aunt, Maggie Horton, tells Lucas he will feel compelled to drink until he is truthful about his feelings. Lucas manages to control the drinking, especially after Sami is injured at the DiMera Mansion and nearly dies. While she is in the hospital recovering, Lucas keeps fantasizing about her. He continues to help Sami adjust after she gets out of the hospital.

Lucas, as well as his mother, is one of the main suspects when the Salem Stalker starts a murder spree. When the Stalker's identity is revealed to be Sami's mother, Marlena Evans, Lucas comforts Sami. She and Lucas grow closer as he helps her through this difficult time, and they finally made love again. Lucas even proposes to Sami, but with a caveat: she has to promise to redeem herself and never lie to him again.

Sami and Lucas become engaged, but Kate does everything in her power to make sure they never walk down the aisle. She brings Sami's ex, Brandon Walker, back to town. Kate has Sami and Brandon drugged and put into bed with each other, where Lucas finds them together on the morning of the wedding, and he is devastated. As much as he loves Sami, he can't forgive her for this. He ripped up the marriage license and swears he never wants anything else to do with her. Sami tries to convince him that Kate is responsible, but his mother smooth-talks him and he only further blames his ex-fiancé.

Lucas joins the team to rescue his half-brother Philip Kiriakis, unaware that Sami (disguised as Stan) has infiltrated the group with a plan of her own. Back in Salem, with Philip's rescue successful, Lucas and Sami grow close again and became engaged. On their wedding day, Lucas's mother arrives at the chapel dressed in Sami's Stan costume. She exposes Sami's escapades, and Lucas dumps Sami at the altar. Austin, arriving for his half-brother's wedding, shows up just in time to comfort Sami.

Later, Lucas accepts a job with his former stepfather, Victor Kiriakis, and travels to California to investigate a possible takeover of High Style. To his surprise, his old flame Carrie Brady has left Mike Horton in India and is the head of the company. Lucas convinces her to return to Salem. In Salem, Carrie and Austin seem to reconnect; but then Carrie admits she has feelings for Lucas, too.

Carrie agrees to marry Lucas, although she loves Austin, because she thinks (because of a plot of Sami's) that she can not have healthy children with Austin. She also believes that she is pregnant with Lucas's child. She and Lucas move into an apartment across from Austin and Sami, who have seemingly reconciled. Shortly after Carrie's wedding to Lucas, she realizes that she was never pregnant at all. That, along with the sexual tension between the two mismatched couples, results in a quick annulment for Carrie and Lucas.

Meanwhile, Austin and Sami became engaged, but on her wedding day Sami calls off her wedding to Austin because of a blackmail note delivered by a mysterious gloved hand.

Sami begins a short relationship with her neighbor EJ Wells (EJ DiMera, who she later discovers to be a son of Stefano DiMera. Lucas becomes jealous of the relationship and with the help of their son Will, Lucas and Sami are reunited. While away on a ski trip, snow causes the roof of their cabin to fall on Lucas, and he is knocked unconscious. Sami leaves to find help and flags down a car driving by. In the car is EJ, presumably fleeing after shooting John Black. EJ tells Sami that he will help her save Lucas if she lets him have sex with her. She is disgusted, immediately referring to his proposal as rape, but unwillingly submits to save Lucas' life.

Sami becomes pregnant, and she and Lucas become closer than ever. Lucas proposes to her, and they become engaged again. Unlike the many other times, this time they get married successfully. On their wedding night, Sami confesses everything to Lucas about EJ and the questionable paternity of the baby. Lucas is distraught, wanting to kill EJ for raping her. He expresses shame over the man he has been – not standing by Sami in the past – and tearfully apologizes, stating it is his fault Sami felt she couldn't come to him after being raped and tormented by EJ. He vows to be a better man for her, the kind she can depend on.

After taking an amino test, they find found out that Sami isn't having one baby, but two babies. Kate blackmails Nick Fallon, to create a fake report that says EJ is the father of the babies. However, Nick actually runs the test, and the results say that Lucas is the father. Sami gives birth to the twins, a boy and a girl. EJ claims that the twins do not look alike even for fraternal twins, and a second DNA test is done. This time the test reveals that the girl, Allie Horton, is the daughter of Lucas, and the boy Johnny DiMera is the son of EJ.

EJ's crime lord father, Stefano DiMera blackmails Sami to end her marriage with Lucas, and marry EJ instead. EJ is shot at their wedding, by a hidden assailant. There are several shots, and one hits and nearly kills EJ. Lucas tells Kate that he hired a nurse to watch Johnny and Allie and went to the church and shot EJ. Lucas then confesses to the police, and he is sent to Statesville prison. Mickey Horton arranges for Lucas to finish his sentence with house arrest, so he can be at home with his family. He will have to wear an ankle monitor at all times, and follow the release terms to a "T.". Mickey tells Lucas that Sami has taken the twins and moved into the DiMera mansion with John and Marlena. Lucas goes there, and walks in on EJ and Sami having sex. Sami had promised Lucas she would not sleep with EJ, and Lucas can't believe that Sami has betrayed him. Sami apologizes to Lucas and vows to be true to him, but Lucas can't forgive her. Lucas soon discovers a way to remove his ankle monitor without the alarms sounding. Lucas develops a friendship with Chloe Lane, and goes to meet her at the Salem Inn. While in the elevator there, the power goes out, and Lucas and Chloe end up making love.

Lucas is soon discovered and sent back to Statesville prison, but EJ drops the charges and Lucas is once again released. He moves into the Horton cabin and invites his new girlfriend, Chloe Lane to move in with him.

After Sami witnesses a murder, she goes into witness protection, and Allie moves in with Lucas and Chloe, who later get engaged. However, Chloe calls off the engagement, leaving Lucas deeply upset and returning to alcohol. Eventually Chloe reconsiders and she and Lucas elope. Later, when Kate poisons Chloe and frames Daniel Jonas, Lucas learns that Daniel and Chloe had an affair. Furious about Chloe's betrayal, Lucas files for an annulment before leaving town.

Lucas returns to Salem in early 2012 at Sami Brady's request and announces that he is engaged to a woman named Autumn. He also reconnects with Will Horton who is now working for EJ DiMera. He later loses his job at Harth and Home when Stefano DiMera seeks revenge on Kate Roberts for having an affair. In turn, Autumn breaks off the engagement. After his failed engagement, Lucas and Sami are forced to work together when she becomes the CEO of Countess Wilhelmina Cosmetics. During an argument, Sami and Lucas are shocked when Will admits to being gay. Though Lucas initially believes he can deal with it, he has trouble adjusting and discourages Will from dating Sonny Kiriakis. Lucas eventually works through his issues and often gives Will advice on his relationship. Lucas is furious when Sami tries to help EJ prove his innocence in Stefano's apparent murder and breaks up with her. Lucas also supports his sister, Jennifer Horton after the supposedly death of her husband, Jack Deveraux but doesn't approve when she reunites with Daniel Jonas.

In January 2015, Lucas begins to bond with Adrienne Johnson. Their friendship eventually blossoms into an affair while Justin Kiriakis is overseas (apparently also engaged in an affair). They continue their relationship until Kate exposes it to Victor Kiriakis. Victor immediately fires Lucas from Titan and evicts Adrienne from the mansion. Adrienne subsequently distances herself from Lucas, but resumes their relationship after Justin returns to Salem. Lucas is eventually hired by Chad DiMera to head rival Dimera Enterprises sub company "Countess W" as revenge for his mother's meddling. At the end of 2015, Adrienne breaks things off with Lucas to repair her marriage with Justin, although that doesn't work out. Lucas' son Will is supposedly murdered by the serial strangler Ben Weston, and Adrienne supports Lucas through his grief and they become close again. In mid 2016, the couple become engaged. When Chad's marriage to Abigail Deveraux falls apart, Lucas and Adrienne move into the Dimera mansion to assist Chad in raising his newborn son. Adrienne, unknowingly ill with breast cancer, collapses during her wedding ceremony. Lucas, Justin, Kate and Sonny rush her to the hospital, and the wedding is ultimately put off due to her diagnosis. Upon being forced to choose between her ex and her fiancée, the trio decide to put her health and treatment first. After undergoing a double mastectomy, Adrienne chooses Lucas.

When Bonnie Lockhart (a doppelganger of Adrienne) breaks out of prison and switches lives with Adrienne (who is imprisoned, believed to be Bonnie), Bonnie (acting as Adrienne) abruptly "breaks up" with Lucas, who reverts to drinking to quell his loss of both "Adrienne" and Will. The real Adrienne manages to phone Lucas from prison, but because he thinks she dumped him, he gives her short shrift and she doesn't manage to explain her situation and get his help. Eventually Adrienne's brother Steve Johnson realizes who Bonnie is, and her ruse is exposed – in front of Justin – who goes with Steve to get Adrienne out of prison; and Adrienne's heart swings back towards Justin; and the experience of prison has made her want to restore her relationship with Justin, so Adrienne herself then breaks up with Lucas. Lucas nose-dives into alcoholism, and he ignores the appeals of his mom Kate, sister Jennifer, and his Aunt Maggie Horton to get help and enter rehabilitation. Inebriated, he begins having hallucinations of Will. Then Ben Weston breaks out of incarceration and announces that Will is alive. A police investigate ensues, and Sami returns to town, finding Lucas drunk at Will's grave. Sami and Lucas pursue a lead to Memphis. Lucas is actually the first to sees Will alive, but he does not realize it, thinking he is hallucinating. Eventually Sonny and Sami find Will, and despite having lost all memory of his life before being strangled, Will decides to return with them to Salem, where Lucas and Will are finally re-united. However the return of Will is no magic bullet for curing Lucas's alcoholism, and he crashes his car whilst driving under the influence and ends up in hospital. Sami both berates and encourages him to take the first step back to health and enter rehab, and with Sami gunning for him, Lucas finally enters rehab and returns to sobriety. On completing rehab and returning to Salem, he and Will build a new father-son friendship, despite Will not remembering him from before. And Lucas rekindles romance with his ex-wife Chloe Lane, including inviting her to a date at the ice-rink.

Bonnie shows up with a baby girl and says Lucas is the father, However this is later proven false.

In 2021, after learning that there daughter Allie Horton had been raped by Charlie Dale, Sami and Lucas sleep together.
