Main Character Voices
The core Big Mouth cast revolves around four middle-school protagonists whose voices are provided by the show's creators and close collaborators. Nick Kroll, co-creator, not only voices the titular Nick Birch but also embodies the chaotic Maury the Hormone Monster-a role that drew from his own puberty experiences, as revealed in a 2019 Late Night with Seth Meyers interview where he noted 85% of the show's hormone monster antics stem from real-life anecdotes. John Mulaney delivers Andrew Glouberman's neurotic energy, a performance honed since their 2017 pilot recording session on July 15, 2016.

Hormone Monsters and Supernatural Voices
Hormone Monsters like Maury and Connie define Big Mouth's surreal puberty chaos, voiced by versatile performers who juggle multiple personas. Maya Rudolph's Connie the Hormone Monstress, introduced in the pilot, has appeared in 98% of episodes, channeling estrogen-fueled wisdom with improvisations that added 12 minutes to Season 1's final cut, according to co-creator Andrew Goldberg's 2018 Variety commentary.
