Hormone Monster Nick Kroll
The Hormone Monster is the most iconic character Nick Kroll voices in Big Mouth. Presented as a foul-mouthed but oddly caring guide, this monster embodies sexual urges and impulsive decision-making in middle-school kids.
Kroll balances bluster with vulnerability, ensuring the monster is terrifying, funny, and, at times, painfully relatable. The performance turns an abstract biological process into a personality-packed mentor whose advice is frequently questionable but always entertaining.
Lizard Boy Role
Personality and Dynamics
Lizard Boy represents a quieter, more anxious side of adolescence. As one of the main kids’ friends, he often reacts with nervous caution, contrasting with the louder impulses of the Hormone Monster.
Function in the Group
Lizard Boy serves as the grounding presence, offering cautious logic that is sometimes ignored but often proves wise. His reptilian appearance underscores the show’s theme that everyone feels like a bit of an outsider during puberty.
Secondary Voices and Satirical Adults
Beyond the core monster and kid characters, Nick Kroll populates Big Mouth with a rotating gallery of satirical adult figures. These voices skewer parenting styles, school authority, and societal expectations around sexuality.
Through exaggerated accents, misplaced confidence, and absurd priorities, these brief but sharp appearances highlight how adults often misunderstand or mishandle teenage confusion. Kroll uses these roles to sharpen the show’s social commentary without overshadowing the central kids’ journey.
Coach Steve and Authority Figures
Coach Steve Development
Coach Steve begins as a clueless, easily offended gym teacher but evolves into a surprisingly sincere mentor. Kroll gives him a distinctive vocal wobble and earnestness that make his missteps painfully funny and his rare moments of insight genuinely touching.
Authority and Tone Balance
By playing Coach Steve and other authority figures, Kroll helps the show critique rigid systems while still rooting for the adults who try, awkwardly, to do right. This layered approach keeps the satire pointed but not entirely cynical.
