Bill Spencer, Jr. is the previously unknown son of publishing magnate Bill Spencer, Sr. They had never been close, but when the elder Spencer died, Bill came to Los Angeles to carry out his father's last wish: to avenge his one true love, Stephanie Forrester, by destroying Eric Forrester and Forrester Creations. Bill encouraged Stephanie, who had defected to rival fashion house Jackie M, to rant about the Logans in a damaging video blog. Eric refused to sell Forrester to Bill, who blackmailed Eric with the knowledge that Eric had hired an illegal immigrant years ago. But Stephanie recorded the conversation and threatened to go public unless Bill backed off.
A consummate womanizer, Bill put the moves on an unresponsive Donna Logan. Later, Bill met Donna's sister, Katie Logan. Fresh from a breakup with Nick Marone, Katie got drunk at the Cafe Russe, but Bill chose not to take advantage of her. Instead, Bill got to know Katie, who challenged Bill's tendency to be a shark. When Katie learned of Bill Sr.'s directive, she questioned Bill's feelings, but Bill insisted his devotion was genuine and proposed. Bill knew Katie wanted to do something special after a second chance at life via a heart transplant, so when Bill finally secured Forrester Creations, he made Katie its CEO.
Young Steffy Forrester was intrigued by Bill and kissed him. But Bill still married Katie in her old San Fernando Valley neighborhood. Bill laughed when the Forresters unsuccessfully tried to sabotage him by creating the ugly Dare fashion line. Bill nearly gave in to his attraction to Steffy until Steffy stole Katie's engagement ring and swore she'd take it to Katie if Bill didn't return Forrester to her family. Bill fumed and vowed revenge, but secretly admired Steffy's ruthless behavior.
Bill befriended Donna, whose marriage to Eric was in trouble, and encouraged her to ask for half of Eric's Forrester stock in a divorce. Now thinking of the Logans as family, Bill offered to join forces with patriarch Stephen Logan in a fight against Eric. Bill blasted his right-hand man Justin Barber for exposing Donna's sister, Brooke Logan, in a sex scandal, yet himself exposed Brooke's daughter, Bridget Forrester, in a paternity scandal, saying he'd already given the Logans a free pass. Bill bought the 12.5% of Forrester that Donna had been awarded and later tried to buy Steffy's 25% share.
Bill soon learned that Spencer Publications intern Liam Cooper was his son, the result of a long-ago affair with Kelly Cooper, who had died. Barracuda Bill clashed with the forthright Liam, disapproving of Liam dating the gentle Hope Logan; Bill put pressure on Hope's ex-boyfriend Oliver Jones to take Hope back and threw a party declaring Liam "the world's most eligible bachelor." But Bill went ballistic when social climbing Amber Moore named Liam as the father of her baby. When a $500,000 bribe didn't work, Bill moved Amber into a cliff house with a faulty balcony, hoping Amber would fall to her death. When Katie learned of Bill's plot, she walked out, only agreeing to return if Bill sought therapy.
Bill snarked his way through sessions with Dr. Taylor Hayes and seemingly made up with Katie off-screen. Then Steffy's brother, Thomas Forrester, went missing at sea, so Bill used his massive resources to rescue Thomas; Bill fell for Steffy and began a full-blown affair, but before they could consummate it, Taylor caught them in bed. Taylor exposed Bill at Katie's surprise vow renewal ceremony, causing Katie to have a heart attack. Though Bill had been ready to leave Katie for Steffy, he opted to stay with Katie.
After Steffy fell for Liam, Bill sent Steffy to seduce Liam away from Hope. When Hope saw Liam kissing Steffy, she left her engagement ring on Liam's mantel; Bill capitalized on Liam offering the ring to Steffy by sending them to Aspen to get married. Hope followed, so Bill had her trapped in a gondola where she was forced to watch the ceremony. Knowing Liam wanted to return to Hope, Bill took advantage when Steffy was injured in an ATV accident and faked an MRI to read that Steffy had a life-threatening blood clot so Liam would feel obligated to stay with Steffy. Katie found out and threatened to tell Liam, so Bill locked Katie in a tower, finding himself alone after Katie escaped and exposed him. Before long, Bill and Katie again resolved their problems off-screen, though Bill fantasized about Brooke one night at dinner.
Bill's half-sister, Karen Spencer, relocated from New York with Danielle. When Bill found out Danielle was Karen's spouse, Karen confessed she'd been secretive about her because she feared Bill's reaction, but Bill accepted the couple. Bill wouldn't accept Hope, however, and persecuted her by siccing paparazzi on her and bribing a warden to break Hope's father, Deacon Sharpe, out of jail, hoping Deacon would prevent Hope from marrying Liam in Italy. Later, Katie told Bill she was pregnant; Bill ordered her to abort, admitting he was afraid heart patient Katie might die carrying a baby. Bill warmed to the idea of becoming a father, but when Katie found Deacon in Bill's office and learned of Bill's illegal activities, Katie went into premature labor and flatlined on the operating table. Katie recovered, but Bill only escaped prosecution because the Logans wanted to protect baby Will. Deacon tried to blackmail Bill, who threatened to have Deacon killed.
Katie slid into postpartum depression and disappeared; Bill and Brooke followed clues to Aspen, finding a note from Katie asking for a divorce. Bill and Brooke kissed, but when they returned home, Katie, who had been terrified of orphaning Will and saw Brooke as a motherly replacement, announced she wanted her life back. Bill continued to think of Brooke and encouraged her to reboot her once-successful lingerie line, which annoyed Katie. Meanwhile, Karen's daughter, Caroline Spencer, got wind of Bill's association with Deacon and fell over a balcony while confronting Bill; Bill briefly stood accused of pushing Caroline. Hope eventually found out about Deacon and bashed her way into Bill's house with a golf club, but when Liam shunned Bill, Dollar Bill lived up to his name by stabbing himself with his sword necklace to get Liam's sympathy, secretly placing his money pouch under his shirt to cushion the blow.
Bill began drinking excessively and balked at the intervention Katie arranged, so Bill asked Brooke to keep it a secret when he crashed his car driving drunk. When Katie found Bill convalescing in Brooke's bed, Katie took off her wedding ring and demanded a divorce; Bill now felt free to make love to Brooke, but their afterglow was interrupted by the news that Katie had been hospitalized with heart failure. Katie wanted Bill back so Bill tried to make it work, though Bill was thrown when Brooke reported miscarrying his baby. Taylor found out about Bill's affair with Brooke and exposed them during Brooke's birthday party; Bill agreed to give Katie 1% of Spencer Publications in their divorce, but found himself out of a job when Katie sold her share to majority stockholder Karen, who fired Bill and made Katie CEO.
When Caroline lamented that her beau, Rick Forrester, had eyes for Maya Avant, Bill learned that Maya had been wrongly convicted of a crime and was not to go near her ex-boyfriend, Jesse Graves. Bill arranged for Maya to run into Jesse and be photographed with him; Maya resisted Bill's blackmail, and Rick locked Bill in a mock jail cell to teach him a lesson. Later, Bill discovered he had another long-lost son in Wyatt Fuller as a result of a short fling with jewelry designer Quinn Fuller. Wyatt and Bill clashed over Bill's current affair with Brooke until Brooke played peacemaker for them.
It made Bill happy being able to babysit Will, but Bill didn't know that Katie was only allowing it so she could spy on Bill and Brooke with hidden cameras. When Bill found out, he followed Brooke to Monte Carlo and convinced her to give their relationship a chance. While mountain climbing in Aspen, Bill nearly fell to his death, then suddenly reconciled with Katie, asking her to sign documents that would return control of Spencer Publications to him and give him join custody of Will. Bill ran to Brooke bragging how he'd tricked Katie, but Brooke replaced his papers with leaves and threw him out.
Bill sparred with Quinn, who felt Bill favored Liam over Wyatt; Quinn jabbed Bill with his sword necklace and licked it from her finger. Later, unhappy that Brooke had agreed to remarry longtime paramour Ridge Forrester, Bill got drunk and had raucous S&M sex with Quinn. After Katie stopped the wedding because she had fallen for Ridge herself, Bill and Brooke slowly found their way back together again. Bill was pleased when Brooke produced the papers Katie had signed and used them to reinstate Bill as CEO of Spencer.
Bill planned an elaborate wedding for Brooke in the United Arab Emirates. Ridge, who bristled at the idea of Bill becoming a stepfather to R.J., his son with Brooke, got hold of a selfie Quinn had taken in bed with Bill and ran to the Middle East, convinced Bill had been unfaithful to Brooke. After Ridge punched Bill and dragged Brooke away to a helicopter, Bill ordered Justin, the pilot, to "cool him off" -- Justin banked the chopper, and Ridge fell into the Persian Gulf. Having not intended to hurt Ridge, Bill organized a search team and was relieved when Ridge returned with an impaired memory. Bill pressured Brooke to marry him immediately, but soon Ridge traced the accident back to Bill and commandeered Bill's helicopter, threatening to throw Bill out of it unless he confessed. Bill lost Brooke when she was told how Bill had rendered Ridge unable to design.
After Ridge's ability was restored, Bill interrupted Deacon's proposal to Brooke with a proposal of his own; Bill hid his hurt when Brooke moved to Milan to find herself. Bill reconnected with Katie, outraged to hear that ladykiller Ridge had betrayed Katie by kissing Caroline. Bill had a knock-down-drag-out fight with Ridge, accidentally referring to Caroline as his daughter instead of his niece. Continuing to find himself in the role of referee between sons Liam and Wyatt, who were fighting over Hope, Bill tried to goad Quinn into jumping off a building for her inadvertent part in Hope miscarrying Wyatt's baby.
Bill wanted to reunite with Katie, who was gunshy after his affair with Brooke. After Bill made Katie vice president of Spencer and deemed himself a changed man, he convinced Katie to accept his proposal. During Bill and Katie's wedding, Brooke, who had come home, uncharacteristically made drunken asides; Bill assured the worried Katie that Brooke wasn't an alcoholic.
Later, Bill was enraged when Rick, who had married Caroline and become CEO of Forrester, retaliated against Caroline for her involvement with Ridge by shooting at them and taking Maya as his mistress. Bill threatened to make Maya's prison past stick, but found the perfect ammunition when Liam and Wyatt discovered that Maya was actually transgender, which Rick knew nothing about. Ignoring opposition from Katie and his sons, Bill exposed Maya in his magazines. Bill toyed with Rick and Ridge when they came to him separately asking Bill to transfer his 12.5% stake in Forrester and give them controlling interest in the company; when Bill told Rick that Maya would have to go because she was a disgrace, Bill found Rick's fist in his face. Ultimately, Bill signed his 12.5% to Liam, who combined shares with Ridge, Steffy, and Thomas and forced Rick out of the CEO chair.
At Katie's urging, Bill apologized to Maya for making a public spectacle of her, adding that he respected Maya for withstanding it. Bill continued counseling his embattled sons, refusing Wyatt's request to bankroll a new fashion house for his girlfriend, Ivy Forrester. Bill was pleased when Liam and Steffy reunited; Bill even played football with the Forrester men at Thanksgiving.
After Katie insisted they offer Brooke a job editing Eye on Fashion, Bill was speechless as Brooke admitted she still thought of him romantically. This prompted Bill to have fantasies about Brooke, which he kept in check, but Bill soon admitted to Brooke that he continued to think of her as well. Bill tried to calm Katie down after she overheard Brooke calling Bill the love of her life and turned her back on Brooke; Bill shared Eric's concern about Katie and Brooke's sisterly relationship, and watched as Katie rejected Brooke's olive branch upon discovering a photo album Brooke kept of Bill.
Bill confronted a hostile Katie about her increased alcohol consumption after little Will couldn't rouse her. Frustrated when Katie wouldn't accept his reassurances, Bill was unable to make love to her and met with Brooke to discuss Katie's descent into alcoholism. After Katie caught them and accused Brooke of trying a new tack to land him, Bill insisted that Katie go back on her antidepressants and wondered if her postpartum depression was resurfacing. During a dinner with Katie and Brooke, Katie flipped out over Bill and Brooke's nonexistent flirting, making Bill wonder if Katie had gone back on her word about giving up alcohol. Bill was furious when Brooke showed him Katie's hidden stash.
Bill was dismayed when Liam took off suddenly, texting he was away at a yoga retreat and suggesting that Bill give Wyatt his job. Bill complied and hired Wyatt on at Spencer, apologizing for the previous judgments he'd made because Quinn was Wyatt's mother. Bill supported Wyatt's deepening relationship with Steffy but left messages for Liam, later agreeing to be best man at Wyatt and Steffy's wedding. However, when a memory impaired Liam returned after having been held by Quinn, Bill went on the warpath and demanded justice, even grilling Quinn's ex-husband, Deacon, regarding Quinn's whereabouts.
