BoJack Horseman,

BoJack Horseman
BoJack often avoids his problems with alcohol, drugs, partying, and impulsive relationships. He also throws himself into his work or convinces himself that "it's too late to change." Instead of facing his guilt or asking for help, he tends to run away or sabotage things when they start to go well.
Diane Nguyen
Diane tries to escape by focusing on her work or writing incessantly. She analyzes everything in such detail that she sometimes gets trapped in her own thoughts. At times, she isolates herself from others and finds it difficult to accept help.
Princess Carolyn
She avoids her problems by overworking. If she's sad or stressed, she fills her schedule with meetings and projects. She always tries to solve other people's problems before her own.
Mr. Peanutbutter
Her way of escaping is through constant optimism. She prefers to make jokes, throw parties, or start new projects rather than talk about difficult emotions. She often smiles even when something hurts.
Todd Chavez
Todd avoids conflict by using humor, witty remarks, and absurd adventures. Instead of confronting a problem directly, he usually distracts himself with a completely different idea.
Hollyhock
When something makes her feel uncomfortable or insecure, she calmly seeks answers, and if she feels that a relationship is harming her, she prefers to distance herself to protect her well-being.
Sarah Lynn
Sarah Lynn tries to fill her emotional void with fame, partying, and substance abuse. Behind her celebrity image, she feels very alone and lost.
Butterscotch Horseman
Butterscotch blames others for his failures and vents his frustration with anger and criticism. He rarely acknowledges his own mistakes.
Beatrice Horseman
Beatrice hides her pain by being cold, critical, and distant. Instead of expressing affection, she represses her emotions and treats others harshly.
Guy
Guy deals with conflicts by speaking calmly and seeking solutions. He is one of the characters with the healthiest coping mechanisms.
