MacNicol. First appearance: "X, the Exterminator." Peter Potamus Peter Potamus (voiced by Joe Alaskey in the first appearance, Chris Edgerly in later appearances) is an employee at Sebben & Sebben. It usually is not clear on what Potamus actually does at Sebben & Sebben; however, in the episode Harvey's Civvy he did defend Harvey Birdman as his lawyer. Peter Potamus is known for always asking everyone "Did you get that thing that I sent ya?" The thing that he sent is usually never explained, unless it is served as a plot device (Ex: Harvey's Civvy, if Shado received the documents for request for discovery). His character started out small, only known for asking if people received "that thing" he sent them, and for being with a woman, only to have another character somehow spot him, by which he always responds "What the?" But soon he became a regular full-time character, usually in meetings with other staff members or as someone witnessing a trial. According to Phil, Potamus is considered to be "An earner" (Ex: In episode Gone Efficien...t, Phil states that chairs are for earners, and we see that Potamus possesses all the chairs). It is implied that he is Jewish. First appearance: "Deadomutt". Judy Ken Sebben / Birdgirl Judy Ken Sebben (voiced by Paget Brewster) is Phil's daughter. Upon meeting Harvey, she professes an immediate interest in his work, dressing up as "Birdgirl" and attempting to secure a position as his sidekick. When she is in costume, she is constantly hit on by Phil, who does not realize that they are related. She is prone to making monologues about her secret identity when she undergoes an internal crisis, often failing to realize that others are within earshot. The monologues, however, are never noticed. Near the end of the series, after Phil is seemingly killed by a bus, she takes control of the law firm. The character has her own sequel series of the same name which aired on April 4, 2021. with a 2nd season debuting in 2022. First appearance: "Bird Girl of Guantanamole", after previously appearing as having been hypnotised during her aerialist career by Mentaur in Birdman and the Galaxy Trio episode "Birdman Meets Birdgirl". Brian O'Brien Brian O'Brien (voiced by Rob Delaney) is the head of human waste at Sebben & Sebben Worldwide. Evie / The Big Ten Evie "The Big Ten" (voiced by Sonia Denis)
