Succession Characters Guide: Main Characters, Alliances, Rivalries, and Best Arcs

A good Succession characters guide has to begin with one hard truth: this is not a show about likable people learning simple lessons. It is a show about damaged, intelligent, often hilarious people whose need for love has been bent into a need for proximity to power. That is why the cast works so well. Every major character is chasing something emotional through the language of business, inheritance, strategy, and image management. Readers looking for the main characters, alliances, rivalries, and best arcs are really asking a deeper question: who in this family and its orbit actually matters, and why does every conversation feel like a knife fight disguised as a meeting?

Logan Roy: the gravitational center everyone orbits

Even when he is off screen, Logan Roy dominates Succession. He is not simply the patriarch or the CEO. He is the show’s force of emotional weather. Every alliance, betrayal, apology, and power play is structured around him because he trained everyone near him to experience affection as conditional and power as the only reliable language.

What makes Logan such a strong character is that the show does not reduce him to one note. He is cruel, manipulative, and often monstrous, but he is also perceptive enough to understand weakness instantly and charismatic enough to keep people returning to him anyway. Brian Cox plays him like a man who cannot imagine a world in which his own appetite is not the center of gravity.

Logan’s real narrative function is to make everyone around him unfinished. Kendall, Shiv, Roman, and Connor are not only competing for a company. They are competing for a form of paternal recognition that never arrives in stable form. That is why even minor gestures from Logan can rearrange the emotional logic of entire episodes.

Kendall Roy: the tragedy at the heart of the show

If Succession has a central tragic figure, it is Kendall. He is the child most openly engineered to inherit and therefore the child most completely broken by that engineering. Kendall wants to be a visionary, a killer, a serious businessman, a modernizer, a moral reformer, and his father all at once. The conflict between those selves is what makes him so compelling.

Kendall’s best scenes are often built around oscillation. He can move from icy corporate performance to desperate emotional collapse in a matter of minutes. Jeremy Strong’s performance makes that volatility feel lived rather than theatrical. Kendall does not only want power. He wants power to prove he deserves love, and he wants love to prove he deserves power. Because neither need is ever securely met, he keeps imploding.

His alliances are also revealing. He reaches for Shiv and Roman when he wants family solidarity, but he also betrays or uses them whenever he sees a path to the throne. He cycles through sincerity, manipulation, grandiosity, and self-loathing so quickly that even his genuine moments feel unstable. That instability is why his arc remains the show’s deepest source of pain.

Shiv Roy: the sharpest political mind and the most disciplined self-protector

Shiv is often the best pure strategist in the family, not because she always wins, but because she sees through performance faster than most of the others. She has political instincts, rhetorical control, and a stronger awareness of optics than Kendall or Roman. She also has the clearest sense of how much contempt she is expected to absorb in rooms still organized by male entitlement.

What makes Shiv great is that the show never lets her remain a symbol of competence. She is brilliant, but she is also proud, insecure, cruel when cornered, and often blind to the limits of her leverage. She assumes she can move between politics, family, and corporate power more smoothly than reality allows. That miscalculation becomes one of the defining tensions of her arc.

Her marriage to Tom is one of the most revealing relationships in the series because it exposes her emotional contradictions. Shiv wants intimacy without vulnerability, loyalty without equivalence, and control without consequence. Yet she is also capable of flashes of real tenderness and pain. Sarah Snook plays her with a hard outer polish that makes every crack feel consequential.

Among the siblings, Shiv often understands Logan best but trusts him too much at exactly the wrong moments. Her alliance with Roman can be cuttingly funny because they understand each other’s barbs, while her relationship with Kendall swings between tactical partnership and mutual disgust. She is often the smartest person in the room and still not free.

Roman Roy: the jester who understands too much

Roman begins as the family’s unserious son, but that is partly camouflage. He is unserious in style, not in perception. Roman often reads rooms quickly, senses weakness instantly, and cuts through euphemism with almost frightening accuracy. The problem is that he has been so emotionally damaged by the Roy family system that his insight rarely matures into stable authority.

Roman is one of the funniest characters on television, yet the humor is inseparable from self-protection. He uses obscenity, mockery, and shock to stay ahead of shame. Kieran Culkin’s performance makes this dynamic extraordinarily layered. Roman can be childish, cruel, and ridiculous, but he can also become the most emotionally transparent sibling in a scene without intending to.

His relationships define him. Logan alternates between belittling him and treating him as a possible successor, which feeds Roman’s deepest confusion about his own worth. Gerri becomes the closest thing he has to a mentor, surrogate authority figure, and impossible emotional fixation. Kendall and Shiv both love and dismiss him. Roman’s tragedy is that he sometimes sees the family system most clearly while remaining one of the least capable of escaping it.

Tom Wambsgans: the outsider who learns the rules best

Tom is one of Succession’s smartest creations because he enters the story as an almost comic climber and ends it as proof that the family’s bloodline was never enough by itself. He looks, at first, like the soft intruder: overpolite, status-anxious, eager to belong. But over time the show reveals that Tom’s hunger is more disciplined than many of the Roys’ own.

He understands subordination better than they do because he has actually lived it. He can flatter, endure humiliation, pivot, and wait. That makes him uniquely dangerous in a world where the Roy siblings often confuse entitlement with destiny. Tom’s survival skills are not glamorous, but they are real.

His marriage to Shiv is essential to both characters. He genuinely wants her, but he also wants what being with her gives him. She wants him close, but not equal. This imbalance produces some of the sharpest writing in the series because every exchange between them can swing from marital intimacy to class contempt to strategic negotiation.

Tom’s relationship with Greg provides the show’s most acidic comic partnership. Their dynamic ranges from mentorship to bullying to dependency to bizarre affection. It is funny because Tom sees in Greg both a servant and a mirror of his own earlier neediness.

Greg Hirsch: the clown who keeps surviving

Greg could have been a one-season novelty. Instead he becomes one of Succession’s most revealing recurring forces. He is awkward, opportunistic, morally flimsy, and frequently ridiculous, yet he keeps finding ways to survive because the show understands that elite systems often reward shameless adaptability.

Greg is important not because he is powerful on his own, but because he is always available to power. He can be used, but he can also gather information, carry messages, leak strategically, and reposition himself. Nicholas Braun plays him as both pathetic and faintly predatory, which keeps the character funny without making him harmless.

His alliance with Tom is the obvious highlight, but Greg also matters as a measuring device. How characters treat Greg often tells the audience something about their current emotional temperature. He is low enough in status to invite abuse and useful enough to remain in circulation. In a show obsessed with hierarchy, that makes him indispensable.

Gerri, Connor, and the wider inner circle

The supporting cast of Succession is unusually strong because the show understands that power is never held only by family. Gerri Kellman is perhaps the most formidable non-family operator in the series. She is controlled, precise, legally minded, and almost always several steps ahead in understanding institutional risk. Her importance lies in her professionalism. She knows how unstable the Roy family is, but she also knows how to use that instability without being swallowed by it too quickly.

Connor Roy, by contrast, seems detached from the main succession struggle, yet he is vital to the show’s emotional and comic balance. He represents what happens when the eldest child exits the main battlefield but never exits the family wound. Connor is absurd, entitled, touching, and strangely self-aware. His presidential run is one of the show’s best examples of how wealth can transform delusion into a lifestyle.

Other figures such as Marcia, Frank, Karl, Hugo, Matsson, Willa, and Rava matter because they reveal different interfaces with Roy power: spousal management, corporate memory, transactional loyalty, outsider disruption, or the cost of proximity.

The alliances that matter most

Succession alliances are rarely pure. They are tactical, temporary, emotionally contaminated, and often self-canceling. Still, some patterns matter.

The most important recurring alliance is among the siblings when they briefly decide to act as a bloc against Logan or outside threats. These moments always feel electrifying because they contain the show’s greatest unrealized possibility: that the Roy children could become stronger together than apart. But they almost never hold. Old resentment, insecurity, and competition always find a way back in.

Tom and Greg form the show’s most durable alliance, even though it is built on humiliation as much as loyalty. Their bond survives because each gives the other something the Roy family does not: usefulness without blood entitlement. Shiv and Tom also operate as an alliance until intimacy and ambition turn them into mutual threats.

Gerri and Roman create one of the strangest alliances in the show, part corporate mentorship and part emotional taboo. It works because both characters need something the other appears to offer: Roman wants steadiness and recognition, while Gerri can use Roman’s status without fully trusting his judgment.

The rivalries that define the drama

The obvious rivalry is Kendall against Logan, but the deeper rivalry is each Roy child against the fantasy of becoming the chosen one. Kendall wants the crown because he was told, implicitly and sometimes explicitly, that it was his. Shiv wants it because she knows she can read power and resents being underestimated. Roman wants it because Logan’s intermittent approval makes him believe he might finally be enough.

Shiv and Kendall have one of the most fascinating sibling rivalries because they are most alike in ambition while despising each other’s methods. Kendall and Roman, meanwhile, fluctuate between fraternity and contempt depending on who seems weakest in the moment. Roman and Shiv often weaponize intimacy: they know exactly where to hit because they know each other too well.

Tom versus Shiv becomes the show’s sharpest marital rivalry once their emotional asymmetry hardens into strategic conflict. Tom versus Kendall matters too, because Tom eventually proves more institutionally survivable than the son who assumed destiny was enough.

Who has the best character arcs?

Kendall has the richest tragic arc because the show keeps asking whether self-knowledge can save someone who still cannot stop wanting the thing that destroys him. Shiv has one of the most intellectually satisfying arcs because every gain exposes a new form of vulnerability. Roman has one of the most psychologically revealing arcs because his apparent unseriousness turns out to be a map of damage.

Tom may have the cleanest long-form arc in structural terms. He enters as a peripheral climber and exits as someone who has learned how to make himself indispensable to power. That does not make him morally superior. It makes him narratively precise. He is the outsider who studies the game better than the heirs.

Gerri deserves special credit for being one of the few characters who consistently feels like an adult in a room full of giant children. Connor, surprisingly, has one of the saddest arcs because his absurdity never fully hides his emotional abandonment.

Why the cast makes the show

Succession works because its characters talk like people who know that language itself is a battlefield. Every insult is a test, every joke hides a status move, every moment of vulnerability risks immediate exploitation. The cast can handle that writing because each performer understands the strange mix of emotional starvation and verbal aggression at the center of the show.

More importantly, the ensemble makes power feel intimate. Corporate takeovers matter because they are family scenes in disguise. Board votes matter because they are twisted love tests. Marriages, friendships, mentorships, and sibling bonds all become forms of negotiation. That is why the characters stay with viewers. They are not just memorable personalities. They are instruments through which the show turns money and inheritance into something painfully human.
