When looking for a memorable TV character whose name starts with B, you often come across the same recycled lists. The problem is that these rankings overlook recent figures or secondary roles that change the dynamics of an entire series. We have selected ten characters starting with B that deserve attention, prioritizing those who bring narrative tension, a tonal shift, or representation that is not found elsewhere.
1. Barney Stinson (How I Met Your Mother)
Barney acts as a revealer of the group. Without him, Ted Mosby’s crew remains a fairly typical circle of New York friends. Barney imposes a comedic rhythm that structures each episode, with his ritualistic lines and absurd plans.
What sets him apart from a simple comic relief is the arc over several seasons that takes him from a caricatured womanizer to a character capable of vulnerability. Reactions vary on the quality of his conclusion in the final season, but his impact on the tone of the series remains hard to contest.
2. Ben Linus (Lost)
Ben Linus enters Lost as an apparently harmless prisoner and ends up redefining the stakes of the series. Michael Emerson transforms a secondary role into a narrative pivot over several seasons.
What stands out is his ability to credibly lie to both other characters and the audience at the same time. Every scene with Ben forces a recalibration of what we thought we knew about the island and its inhabitants. He is a textbook case of a character that elevates the writing around him.
To explore other B characters in series to discover, one can see that the letter B concentrates a surprising number of cult figures.
3. Brienne of Tarth (Game of Thrones)
Brienne arrives in a universe where violence is male by default, and she asks for no permission to impose herself. Her journey does not rely on a spectacular revelation but on a consistency that contrasts with the series’ constant twists.
Her fight against the Hound remains one of the most physical scenes in the entire series. What makes Brienne memorable is the absence of cynicism in a world overflowing with it. She keeps her word, protects those she has sworn to protect, and this simplicity becomes almost subversive in the context of Westeros.
4. Bobby Singer (Supernatural)
Bobby starts as a recurring phone contact for the Winchester brothers before becoming their surrogate father figure. His shabby garage, cap, and straightforward vocabulary provide a concrete anchor in a series that often flirts with pure supernatural.
He remains in this ranking because he fulfills a narrative function that no one else does: he gives the protagonists a place to return to. Without Bobby, Supernatural loses its emotional fixed point.
5. Belly (The Summer I Turned Pretty)
Isabel “Belly” Conklin carries an entire series on a summer love triangle, and what makes her interesting is that she is not written as a passive character waiting to be chosen. She makes decisions, sometimes wrong ones, and the series embraces these mistakes without turning them into moral lessons.
Belly embodies a teenage heroine who has the right to make mistakes without losing the audience’s sympathy. This is less common than one might think in young adult adaptations.
6. Boyd Holbrook in Narcos (agent Steve Murphy being the lead, Boyd plays Crowder) – Boyd Crowder (Justified)
Correction: Boyd Crowder in Justified. Walton Goggins builds an antagonist who refuses to stay in his box. Former miner, reformed supremacist, self-proclaimed preacher, then self-acknowledged criminal, Boyd changes skins every season without it sounding false.
His relationship with Raylan Givens provides the engine for the entire series. Two men from the same county, same origins, opposite trajectories. Justified without Boyd would be a decent procedural. With him, it’s a duel over six seasons.
7. Bunny (The White Lotus)
Bunny is one of those secondary characters who reveal the true subject of a series. In The White Lotus, she exposes class relations and toxic family dynamics with a remarkable economy of dialogue.
Her role in the season highlights how maternal power is exercised through silent presence rather than open conflict. A character underestimated in the first scene who haunts the entire narrative.
8. Bojack (Bojack Horseman)
Bojack Horseman is the most complex animated character produced by a streaming platform. Behind the absurdity of an anthropomorphic horse who is a sitcom star lies an accurate portrait of depression, addiction, and self-sabotage.
The series refuses to redeem him. Each attempt at improvement is followed by a relapse, and the narration never presents this as a twist, but as a documented mechanism. We come out of the series without clear answers about Bojack, and that is precisely what makes him a lasting character.
9. Bella Baxter (The Buccaneers)
Bella Baxter brings a recent angle to the landscape of historical series heroines. While other productions confine their female characters within period conventions, The Buccaneers gives her a freedom of tone that reflects contemporary production choices.
Her emancipation does not come through discourse but through concrete actions in the narrative. She is a character worth discovering for those who think that historical series are a fixed genre.
10. Brick Heck (The Middle)
Brick is the quirky youngest child of the Heck family, the one who whispers his own lines at the end of a dialogue and reads books in all circumstances. He brings a comedic offset that relies on no special effects or forced punchlines.
In a family series often compared to Malcolm, Brick occupies a unique niche: the introverted child in a noisy household. His humor comes from the constant contrast between his calm and the chaos around him. A character that you might not notice right away, but eventually comes to be seen as the quiet heart of the series.
These ten characters starting with B cover very different registers, from family comedy to historical drama. The common thread remains their ability to change the series that hosts them. Remove one of them, and the narrative collapses or loses its flavor, which remains the best test to distinguish a memorable character from a simply well-written role.
