Early life Kendall Logan Roy was born in England in 1978 to media mogul Logan Roy and English aristocrat Lady Caroline Collingwood. The first son of the marriage, he has two younger siblings Roman and Siobhan "Shiv" Roy, and an older half-brother, Connor, from Logan's first marriage. As his parents divorced, he moved to New York City with his father and siblings. At age seven, while at a candy kitchen in
Long Island, Logan promised Kendall that Kendall would take the reins of the company after Logan's retirement. Kendall attended the
all-male Buckley School, where he met best friend Stewy Hosseini. They subsequently went to
Harvard University, where Kendall was part of
The Harvard Lampoon's staff. During that time they often attended parties and did
cocaine together. After graduating, he spent time in
Shanghai learning the fundamentals of the family business; there, he spent time with Nate Soffrelli, who later became involved with Shiv. With his wife, Rava, Kendall has an adopted daughter, Sophie, and a son, Iverson, who is implied to have been conceived via
artificial insemination. His substance abuse issues led to the breakdown of his marriage to Rava and a months-long stint in
rehab.
Appearances Season 1 Kendall is Logan's presumed heir upon the latter's retirement, but Logan announces during his 80th birthday that he will remain CEO indefinitely. During this time, Kendall narrowly negotiates Waystar's acquisition of media startup Vaulter, whose founder Lawrence Yee holds Kendall and Waystar in contempt. After Logan suffers a stroke and is admitted to the hospital, it is agreed that Kendall become acting CEO with Roman as COO. Kendall consults Stewy's financial aid to prevent having to repay Waystar's $3 billion debt from its expansion into parks, unaware that Stewy is allied with Logan's longtime rival Sandy Furness. Logan eventually recovers from his stroke and announces that he will return as CEO, but continues displaying erratic behavior. Kendall plots a vote of no confidence against his father, but it fails and Logan fires him for his disloyalty. A bitter Kendall relapses on drugs during a family therapy retreat, and spends the following weeks aggressively investing in startups while on a binge. During Tom's bachelor party, Kendall is approached by Stewy and Sandy, who offer to buy out his share of Waystar for half a billion; a vengeful Kendall instead proposes a hostile takeover that will grant them a controlling interest in the company and name him CEO. Kendall serves Logan with the bid during Shiv's wedding. However, he later gets into a car accident while under the influence of drugs, resulting in the death of a caterer from the wedding. Logan promises to make the case go away if Kendall backs out of the takeover; Kendall obliges and breaks down crying in his father's arms.
Season 2 Over the following months, Kendall, still reeling from the trauma of the accident, becomes staunchly loyal to Logan, who names him his co-COO alongside Roman in order to help fight the takeover bid. Logan forces him to shut down Vaulter, as its poor performance is proving a financial sink for Waystar. Logan decides to buy rival news giant Pierce Global Media (PGM); during a weekend retreat between the Roys and Pierces, Kendall begins a sexual relationship with Naomi Pierce, a fellow addict and influential board member whom he convinces to back the acquisition. However, the deal ultimately fails after Waystar's decades-long cover-up of sexual exploitation on the company's cruise lines becomes public. The Roys are called to testify before the Senate, and Kendall delivers a combative performance that wins them the case but sets the company back against the shareholders, who demand accountability. Despite being privately advised by investors to accept responsibility himself, Logan chooses Kendall to take the fall for the scandal, as he was across the cover-up during his tenure as CEO. Kendall obliges, and asks his father whether he ever saw him fit to run the company, but Logan tells him he is not the "killer" he must be in order to succeed. The following morning, Kendall gives a press conference where he is set to accept the blame for the scandal, but he suddenly deviates from his prepared remarks and names Logan personally responsible for overseeing the cover-up of the crimes.
Season 3 Kendall takes on a manic, self-aggrandizing zeal following his announcement, frequently ignoring the advice of his lawyers and PR consultants in favor of chasing publicity. He also unsuccessfully attempts to convince his siblings to join him against their father. Kendall's legal battle with Waystar dissipates after his poor performance in a testimony to the Department of Justice, who deem the documents Kendall has recovered on the cruises scandal to be insufficient legal ammunition against Waystar and instead reach a settlement with the company. On his 40th birthday, Kendall receives an offer from Logan to buy out his shares in the company for $2 billion. Kendall gives up on trying to defeat his father and decides to take the buyout to permanently uncouple himself from the family, but Logan ultimately refuses his request and rebuffs him, prompting a despondent Kendall to attempt suicide by drowning while in Tuscany for his mother's wedding. During the wedding, Kendall suffers an emotional breakdown and confesses his role in the fatal car accident at Shiv's wedding to Shiv and Roman, who support him. The three learn Logan is selling Waystar to tech giant GoJo without their input, jeopardizing their control of the company, and decide to form a supermajority to veto Logan's decision. However, Tom tips off Logan on the children's revolt, allowing him to renegotiate his divorce settlement with Caroline prior to the children's arrival and deprive them of their voting power in the holding company. The siblings are effectively left powerless within Waystar.
Season 4 Six months later, Kendall, Roman and Shiv are estranged from Logan and planning an independent media venture they call "The Hundred". However, on Logan's birthday, they learn their father is attempting to buy PGM again, and successfully outbid him. They then partner with Stewy and Sandi, who want to negotiate a price increase for the GoJo sale, to spitefully pressure Logan into renegotiating the deal with GoJo founder Lukas Matsson. However, Logan dies en route to his meeting with Matsson in Sweden; the siblings learn of his death while at Connor's wedding. At Logan's wake, Frank finds an undated document in Logan's safe naming Kendall his successor. Kendall is profoundly affected by this news, but agrees to run the company alongside Roman to honor the stipulation that COO take over. Drawn to the power of being CEO and skeptical of Matsson's vision for the company, Kendall enlists Roman's aid in sabotaging the GoJo deal. He delivers a bombastic product launch at Waystar's Investor Day in hopes of driving up the company's valuation and rendering GoJo's acquisition untenable, and later attempts to block the sale on regulatory grounds. Upon learning that GoJo has inflated its subscriber count in India, Kendall proposes to Frank that Waystar buy GoJo with Kendall as the sole CEO. On election night, Kendall is uncomfortable with Mencken due to blowback from his extreme politics affecting his daughter Sophie. Kendall ponders backing Jiménez for his family's sake, but learns from Greg that Shiv is working with Matsson; hurt by his sister's betrayal, he throws in his support for Mencken. The Roys arrive at Logan's funeral amidst street protests that have broken out following the announcement of Mencken's win. Upon learning that Shiv has brokered a deal to allow the GoJo deal to go through in exchange for naming an American CEO, Kendall enlists Roman and Hugo to join him against Shiv at the final board vote on the acquisition. The next day Kendall scrambles to secure board votes to block the GoJo deal. He and Shiv visit Caroline's estate in Barbados, where Roman is recovering from his wounds. Upon learning that Matsson plans to betray her, Shiv joins forces with Kendall. The siblings then agree to let Kendall take over, forming a voting bloc. The board comes to a 6–6 tie over selling to GoJo. Shiv, however, has second thoughts about Kendall's competence, and votes in favor of the deal despite Kendall's protests. Tom is appointed CEO with Shiv by his side; Kendall, followed by Colin, takes a stroll down
Battery Park and contemplates his future. ==Reception==
