Big Mouth Characters: The Complete Guide To Every Hormone Monster And Teen

Ever wondered what your hormones would sound like if they had a voice, a personality, and a penchant for terrible advice? Welcome to the wildly inventive, hilariously uncomfortable, and surprisingly heartfelt world of Netflix's Big Mouth. This isn't just an animated sitcom; it's a chaotic, hormone-fueled roadmap through the nightmare and wonder of puberty. At its core, the show's genius lies in its vast and vibrant ensemble of characters, each a distorted mirror reflecting the anxieties, absurdities, and awkward moments of growing up. Whether they're pubescent teens, monstrous personifications of feelings, or utterly unhinged parents, every character is designed to make you laugh, cringe, and ultimately feel seen. This definitive guide will navigate you through the entire Big Mouth characters roster, from the core friend group to the most bizarre supernatural entities, explaining who they are, who voices them, and why they’re essential to the show's chaotic charm.

The World of Big Mouth: More Than Just a Coming-of-Age Story

Before diving into the sprawling cast, it’s crucial to understand the show's foundation. Big Mouth is an American adult animated sitcom created by Nick Kroll, Andrew Goldberg, Mark Levin, and Jennifer Flackett for Netflix. It is based on Kroll and Goldberg's own teenage years growing up in the suburbs of New York City. The series masterfully blends crude, unfiltered humor with poignant, honest explorations of identity, sexuality, and mental health. It follows a group of adolescents on the precipice of and deep within puberty, whose lives are turned upside down by the literal manifestations of their hormones, insecurities, and desires.

The show aired for eight seasons between 2017 and 2025, with Season 8 serving as the announced final season. This eight-season run allowed for an extraordinary expansion of its universe, introducing a staggering number of characters. In fact, according to the Big Mouth section on the Behind The Voice Actors (BTVA) database, there are 241 characters in the entire franchise. Of these, 8 have appeared as multiple versions across different titles or mediums, while 233 are unique to a single appearance. This sheer volume speaks to the show's commitment to exploring every nook and cranny of the adolescent experience, no matter how bizarre or specific.

A big reason Big Mouth works is its characters. As many fans note, most of them are deliberately unlikeable—self-obsessed, ignorant, or wildly inappropriate. Yet, the situations they navigate are universally relatable. You recognize their flawed logic because, believe it or not, you’ve mostly been there too. This guide will unpack that magic, introducing you to the key players who make the series so memorable.

The Core Friend Group: Navigating Puberty's Front Lines

At the heart of the series are four central friends whose journeys form the primary narrative arc through most seasons. Their dynamic is the anchor that grounds the show's wildest surreal elements.

Andrew Glouberman: The Anxious Protagonist

Andrew is our primary viewpoint character, a sweet but deeply anxious and hormonally confused boy. He is learning that first hand as he experiences the nightmare that is growing up in this exaggerated world. His journey from a terrified, masturbation-obsessed kid to a young man beginning to understand his emotions and identity is the show's emotional backbone. His constant battles with his Hormone Monster, Maury, and later his Shame Wizard, define much of his early development.

Nick Birch: The Late Bloomer

Nick is Andrew's best friend, characterized by his small stature, childlike voice (which sticks around far longer than he'd like), and desperate desire to be "cool." His puberty is a delayed, chaotic event, marked by his Hormone Monster, Connie, being a hyper-sexualized, chaotic force that contrasts sharply with his own naivete. Nick's arc is about embracing his own pace and rejecting toxic masculinity.

Jessi Glaser: The Cynical Realist

Jessi is Andrew's other best friend, a sharp, witty, and deeply cynical girl who provides a crucial female perspective on the chaos. Her journey involves navigating her first period, her parents' messy divorce, and her own complex feelings about boys and her body. Her Hormone Monster is a glamorous, manipulative entity named "The Hormone Monstress" (later revealed to be named "Jesse"), who often encourages her worst impulses.

Jay Glazer: The Hedonist

Jay is the group's hedonistic, often selfish, but weirdly loyal friend. He is obsessed with sex, sports, and being perceived as a "man." His Hormone Monster is a crude, caveman-like creature named "Rick" who embodies pure, unthinking id. Jay's character provides much of the show's most raunchy comedy, but his storylines also touch on deeper issues of emotional availability and family trauma.

The Adult Cast: Flawed Parents and Authority Figures

The adults in Big Mouth are often as immature, selfish, and confused as the children, providing a darkly comic mirror to the kids' struggles.

The Glouberman Parents

• Bernard Glouberman (voiced by Fred Armisen): Andrew's deeply neurotic, anxiety-ridden, and often emasculated father. His constant worrying and bizarre fixations are a source of both comedy and pathos.
• Barbara Glouberman (voiced by Maya Rudolph): Andrew's mother, who is trying to be the "cool mom" while suppressing her own frustrations and desires. Her journey through menopause is a major plot point, personified by her own "Menopause Monster."

The Birch Parents

• Elliott Birch (voiced by Nick Kroll): Nick's father, a well-meaning but profoundly awkward and emotionally stunted man-child. His attempts at "dad talk" are legendary for their failure.
• Judy Birch (voiced by Jessi Klein): Nick's mother, a therapist who is ironically terrible at handling her own family's emotions. Her clinical detachment often clashes with the raw chaos at home.

The Glaser Parents

• Greg Glaser (voiced by John Mulaney): Jessi's divorced father, a pathetic, self-pitying man who struggles with basic adulting.
• Michael Glaser (voiced by Jordan Peele in early seasons, later by other actors): Jessi's more stable, but still flawed, mother.

Other Key Adults

• Coach Steve (voiced by Nick Kroll): The gym teacher and later a guidance counselor. He is a walking id, intellectually disabled, sexually inappropriate, and yet possesses a strange, innocent wisdom. He is one of the show's most bizarrely popular characters.
• Mr. Terry Lizer (voiced by Jason Mantzoukas): The girls' basketball coach, a washed-up former athlete with a massive ego, a crippling gambling addiction, and a ponytail that defies physics.
• Ronnie (voiced by Paul Dano): The extremely creepy, agoraphobic neighbor who becomes a bizarre friend to Jay.
• Devon LeSeven (voiced by Jak Knight): A cool, older student who serves as a toxic idol for Jay before his own story takes a tragic turn.

The Supernatural Cast: Personifications of the Psyche

This is where Big Mouth truly defines its brand. The Department of Puberty and its associated entities are literal manifestations of the characters' inner lives.

The Hormone Monsters

Each main character has their own Hormone Monster who embodies their specific sexual and emotional impulses.

• Maury (voiced by Nick Kroll): Andrew's original Hormone Monster. He is a mustachioed, 1970s-inspired, aggressively sexual creature who encourages Andrew's worst, most self-serving impulses. He evolves significantly over the series.
• Connie (voiced by Maya Rudolph): Nick's Hormone Monstress. She is glamorous, manipulative, and obsessed with making Nick "cool" and sexually experienced, often with disastrous results.
• Jesse (voiced by Maria Bamford): Jessi's Hormone Monstress. She is a seductive, cynical figure who encourages Jessi's manipulative and self-destructive tendencies.
• Rick (voiced by Joe Wengert): Jay's primitive, grunting Hormone Monster who represents pure, unthinking lust and aggression.

Other Department of Puberty Entities

• The Shame Wizard (voiced by David Thewlis): A terrifying, dark-cloaked figure who appears when a character does something they perceive as deeply shameful. He is one of the show's most psychologically potent creations.
• The Depression (voiced by Mark Hamill): A heavy, blanket-like entity that smothers its victims. His design and Hamill's weary, crushing voice are perfect.
• The Anxiety (voiced by Nick Kroll): A jittery, chattering creature that lives in the mind, constantly listing worst-case scenarios.
• The Love Bug (voiced by Fred Armisen): A tiny, annoying insect that causes characters to fall in love irrationally.
• The Gremlins (voiced by various): Small, mischievous creatures that represent specific anxieties or bad habits.
• The Hormone Monster's Assistant, "The Pillow" (voiced by Jenny Slate): A literal pillow who assists Maury and provides deadpan commentary.

The Ghosts & Other Spirits

• The Ghost of Duke Ellington (voiced by Jordan Peele): A ghost who haunts the school's music room and becomes an unlikely mentor to Andrew.
• The Ghost of Antonin Scalia (voiced by Nick Kroll): A Supreme Court Justice ghost who haunts the school's debate team.
• The "Squirt" (voiced by Nick Kroll): A mysterious, sentient entity that represents male ejaculation, often appearing at the most inopportune times.

The Voice Cast: A Talented Ensemble

A common question is: "Not every character on Netflix's Big Mouth is voiced by Nick Kroll." While Kroll is the creator and voices a huge number of characters (Andrew, Maury, Nick, Coach Steve, Steve's brother, multiple ghosts, etc.), the show's brilliance lies in its stellar voice cast. Here's a handy guide to the show's voice cast, and who they play.

• Maya Rudolph: Jessi's Hormone Monstress (Jesse), Barbara Glouberman, the Ghost of Aretha Franklin, and several other one-off characters. Her range from seductive to maternal is astounding.
• Jessi Klein: Provides the voice for Jessi Glaser herself. Her performance captures Jessi's sarcasm and vulnerability perfectly.
• John Mulaney: Voices Nick Birch and Mr. Terry Lizer. His signature nervous energy is ideal for both the teenage boy and the desperate coach.
• Jason Mantzoukas: The unmistakable voice of Coach Steve and Mr. Lizer. His ability to deliver lines with unhinged intensity is a comedic powerhouse.
• Ayo Edebiri: Joins the cast later as Missy, a brilliant, kind, and biracial girl navigating her own unique puberty. Edebiri's performance is a masterclass in warmth and comedic timing.
• Fred Armisen: Voices Bernard Glouberman, The Love Bug, and The Pillow, among others.
• Jordan Peele: Originally voiced Michael Glaser and The Ghost of Duke Ellington.
• David Thewlis: Provides the chilling, iconic voice of The Shame Wizard.
• Mark Hamill: Gives a career-defining, deeply empathetic performance as The Depression.
• Guest Stars: The show features a who's who of comedic talent, including Nick Offerman, Kristen Schaal, Seth Morris, Joe Wengert, and many more voicing minor characters, monsters, and one-off jokes.

The Series Finale and Legacy

'Big Mouth' has ended with an eighth and final season, bringing the core group's high school journey to a close. The final season focused on graduation, college decisions, and the characters taking tentative steps into adulthood, while still being haunted (literally) by their hormonal pasts. The ending was widely praised for finding a balance between bawdy humor and genuine emotional payoff, allowing the characters to grow without losing their essential, flawed selves.

Big Mouth Season 7 and the final season continued this tradition, featuring both new and returning characters. New additions like Ayo Edebiri's Missy (who became a main character) and Andrew's new Hormone Monster, "The Hormone Monster 2" or "Him" (voiced by Kroll) refreshed the dynamic. The show consistently proved that its universe could expand while staying true to its core mission: to demystify puberty through absurdity and empathy.

Fan Favorites and Standout Characters

Among the vibrant and diverse cast of characters, a few stand out as fan favorites due to their memorable traits and the roles they play in navigating puberty's complex landscape. So, who are the popular Big Mouth characters? Lists often include:

A Page for Describing Characters: The Ultimate Reference

If you're looking for a full list of the characters in Big Mouth, with images and actors, resources like BTVA (Behind The Voice Actors) and the show's own "Main Character Index"—which categorizes characters into main characters, family, school, supernatural beings (Department of Puberty), and more—are invaluable. These pages serve as the definitive page for describing characters, detailing every one-off ghost, monster, and background teen. They highlight the show's incredible depth; beyond the 241 named characters, there are 236 images of the Big Mouth cast of characters and countless photos of the Big Mouth (show) voice actors in their various roles.

Why the Characters Are the Heart of the Show

Ultimately, a big reason, as with any show, of why 'Big Mouth' works are its characters. They are exaggerated, grotesque, and often offensive caricatures on the surface. But beneath the cartoonish exteriors lies a profound truth-telling. The show uses its supernatural elements not for cheap laughs alone, but as practical metaphors for the internal experience of adolescence. The Shame Wizard isn't just a scary monster; he's the voice in your head after a social blunder. The Depression isn't just a blanket; it's the weight that makes getting out of bed impossible. The Hormone Monsters aren't just perverts; they are the confusing, overwhelming surge of new feelings you can't control.

Even for a cartoon character, going through puberty isn't easy for a young person.Big Mouth validates that difficulty by making it literal, monstrous, and laugh-out-loud funny. It tells its audience that the confusion, the shame, the anxiety, and the sheer weirdness of growing up are universal. The characters, in all their flawed glory, are guides through that landscape. They show us that while the journey is messy, we are not alone in it.

Conclusion: More Than Just a Cartoon

From Nick Birch and Andrew Glouberman to Maury, The Shame Wizard, and Coach Steve, the Big Mouth characters form one of the most inventive and psychologically astute ensembles in modern television. The series, which aired for eight seasons between 2017 and 2025, used its animated format to explore topics live-action often can't, creating a lexicon of monsters that have entered the cultural conversation about mental health and puberty. With 241 characters spanning teens, parents, monsters, and ghosts, the show is a testament to the idea that the inner life of a teenager is a crowded, chaotic, and fascinating place. While the show has ended, its characters will continue to serve as hilarious, horrifying, and helpful companions for anyone who remembers—or is currently enduring—the "nightmare that is growing up." They remind us that sometimes, the best way to face our inner demons is to give them a name, a voice, and a really, really bad mustache.
