Description
Catherine, commonly known as Nurse Catherine, is a character in the Gregory Horror Show universe. She is a pink anthropomorphic lizard who works as a nurse, and her appearance is defined by a white nursing gown, a nurse's cap with a red plus at the center, and a medical badge on her left arm. She is counted among the earliest residents of Gregory House, and a later story arc centers on her work in a mysterious hospital.

In terms of personality, Catherine is best known for a deep and unsettling fascination with drawing blood. She carries an oversized syringe and has a particular interest in human blood, and she frequently turns her attention to the other guests around her. This obsession, along with a quick temper, makes those around her uncomfortable and keeps most people at a distance. Beneath this threatening exterior, she is a lonely figure who genuinely desires love and companionship. Her core motivation is the wish to feel loved and appreciated, while her deepest fear is being unwanted or unloved. That tension shapes her behavior: her attempts to connect with others are repeatedly undermined by the very actions, especially her bloodletting habits, that frighten people away.

Her role in the story is primarily that of a menacing presence among the residents of Gregory House. She is an antagonist figure who poses a danger to those she encounters, and in the video game adaptation she is one of the guests whose bottled soul must be taken; when she catches the player, she menaces them with her syringe. Her key relationships are with the other residents, whom she views as potential sources of blood, and with the proprietor of Gregory House. Because her medical fixation disturbs everyone around her, she struggles to form the close bonds she craves, and other characters tend to avoid her company.

Development-wise, Catherine begins as an unsettling side figure defined by her blood obsession and loneliness, and later expands into a leading character in her own dedicated story, which places her in a strange hospital and explores her nursing role in greater depth. Her notable abilities come from her medical profession: she is a nurse who wields a large syringe, but she uses her medical tools and training in a twisted way, treating blood collection as both a duty and a delight rather than a routine procedure.
