Homeless rabbit, 34 years old, serial killer that has killed over 20 people, secretly an anomaly, likes to come to the hospital to drink coffee (only accepts coffee made by Intern or Secretary). Barney is Intern's best friend and has a crush on Secretary.
Barney jokes about everything, including serious stuff and can be cruel, specially to characters that are certain animal species (Ratthew, Liloana, Head Nurse). Barney can be very rude and sarcastic, but extremely loyal and caring of his friends (Intern, Toby, Secretary) he sometimes flirts with Secretary. he is wanted by the police and Officer Duckman is constantly looking for him, but Intern always hides and defends him.
Jokes mid-seriousness; sharp sarcasm with sudden, protective warmth toward friends.
