Maya Rudolph, Fred Armisen and Jordan Peele
Rudolph voices Connie, Diane Birch and Bonnie. Armisen voices Elliot Birch, Bob and the ghost of Antonin Scalia. Peele voices the Ghost of Duke Ellington, Missy’s father Cyrus and other ghosts. These examples come from Netflix Tudum’s Season 7 guide and are not a full inventory of every role in the series.
John Mulaney and other performers
Mulaney voices Andrew, as well as Mint, Future Andrew and Babe the Blue Ox. The guide also credits Mantzoukas with Jay and Jay’s father, and Wengert with Caleb, Lump Humpman and Joe the Hormone Monster.
Rank #2
Who voices Missy?
Ayo Edebiri is identified as Missy in Netflix Tudum’s later cast guide. Netflix’s Media Center links to its announcement dated August 31, 2020, that Edebiri joined the cast as Missy. These sources establish her casting but do not specify episode-by-episode transition details. The Television Academy’s 2024 Creative Arts Emmy Awards document also identifies Maya Rudolph as Connie the Hormone Monstress in its Big Mouth voice-performance entry; it is an awards record, not a claim here about a win.

No. Netflix’s official title page lists eight seasons, and Netflix Media Center calls Season 8 the final season. Its final-season description follows the Bridgeton teens into high school, with challenges including driving, drugs, sexual inexperience, enthusiastic consent, changing bodies and anxiety about the future. Netflix also identifies Compassion, voiced by Holly Hunter, as a new creature in that season. The principal cast map above is not a complete Season 8 guest-cast roll call.
