Charlotte Moore is a friend of BoJack's and former girlfriend to Herb Kazzaz. She currently resides in Tesuque, just outside Santa Fe, New Mexico, where she owns a store called "Your Deer Friend." She has a husband, Kyle, and two children, Penny and Trip.
Charlotte first appears in a series of flashbacks to BoJack's life in the 80s, when she was still dating Herb and best friends with both Herb and BoJack. At the onset of Herb's success, however, she decides to move to Maine. In "Downer Ending," BoJack has a drug-induced dream where he chose to move to Maine with Charlotte, and lived out a peaceful life while having a daughter together named Harper.
Charlotte later reunites with BoJack at Herb's funeral, after 30 years have passed since they last saw each other. BoJack finds that she had only lived in Maine in the 80s for a month before moving and settling in New Mexico. She hands BoJack her business card and invites him to visit her if he is ever in the area.
BoJack eventually visits Charlotte in the town of Tesuque, New Mexico when he runs away from Los Angeles in "Escape from L.A." She reveals to BoJack for the first time that she has a family, and invites him to stay. BoJack bonds well with her family, and extends his stay upon Charlotte's suggestion. When he returns from playing Charlotte's daughter Penny's surrogate date for her prom, he confides to Charlotte about his struggles and worries, to which she responds that he cannot run away from his problems, and especially himself. In a moment of tenderness, BoJack kisses Charlotte, and asks her to run away with him, confessing that he has loved her all this time. She rejects him, however, reminding him she built a good life with her family and that BoJack painfully brings her sadness.
After BoJack returns to his boat, Charlotte's attention is drawn by one solitary balloon with a glowstick attached floating down; a balloon made earlier in the evening by BoJack and Penny's prom group after ditching the prom. She follows it toward BoJack's boat, where she hears noises coming from within. She then opens the cabin door to catch BoJack and Penny in a compromising position. She angrily orders Penny to go to her room, and demands BoJack leave within half an hour or else she would call the police. Charlotte ends by threatening BoJack that if she catches him trying to contact her or her family again, she would kill him.
She and Penny are indirectly mentioned by BoJack in the Season 3 episode, "Start Spreading The News" after BoJack's libido is ruined. Though Penny receives further mention as well as an appearance, Charlotte has no further ties to the season.
Charlotte is shown to be an easy going, fun loving person, and has always been a good friend to BoJack, Charlotte is sad to see BoJack's self-destructive tendencies and tries her best to steer him in the right direction while avoiding being caught up in his life.
