Cathy Taymor is a character introduced in the second season of the anime, known as Kaleido Star New Wings. She is a professional performer and creative mind working on Broadway in New York City. Cathy is a tall woman with a striking appearance, characterized by her red or burgundy hair cut into an asymmetrical bob and her green or blue eyes. She often wears a necklace and presents herself with a confident, adult demeanor.

In terms of personality, Cathy initially comes across as a hot-headed and somewhat brash individual. She has little patience for what she perceives as pretension or arrogance, and she is notably annoyed by individuals she labels as rich girls, a category in which she initially places the talented but privileged Layla Hamilton. Despite this prickly exterior, Cathy is ultimately a great person who cares deeply about the art of performance. She is highly motivated and always tries to push those around her to be better, acting as a catalyst for growth and emotion in her fellow performers. She is blunt and honest in her assessments, unafraid to voice her dissatisfaction when she feels a performance lacks genuine feeling or connection.

Cathy's role in the story becomes significant when Layla Hamilton, now a star on Broadway, invites the protagonist Sora Naegino to perform with her. Cathy meets Sora during the production Salome in Vegas and is immediately impressed, finding Sora to be a wonderful and entertaining performer. In contrast, she holds a lesser opinion of May Wong, feeling the young acrobat is unable to truly entertain her. Cathy herself becomes a new partner for Layla on Broadway, a professional relationship that seems to cause some initial hurt feelings for Sora. Later, after a poorly received partnership with the skilled but emotionally closed-off Leon Oswald, Cathy joins Layla in returning to the Kaleido Stage, the central setting of the series. At this point, her role shifts to that of a mentor and supporter, as she becomes a partner and an encouraging force for Mia Guillem. She consistently works to motivate and inspire Mia's creative mind, helping the younger woman grow into her role as a stage director.

Her key relationships are primarily professional but have a significant impact on the story. Her partnership with Layla Hamilton evolves from one of initial annoyance to a strong and effective working relationship, with Cathy becoming a trusted collaborator. Her brief partnership with Leon Oswald is marked by frustration, as Cathy criticizes their comeback show for having no emotional connection between them. She develops a strong positive relationship with Sora Naegino, whom she instantly respects as a performer. Most notably, her relationship with Mia Guillem is one of a teacher and guide, as she tries to draw out Mia's potential. It is through Cathy's direct aid and advice that Mia is able to plan and execute the complex Angel's Maneuver for their production of Swan Lake.

Throughout her appearance, Cathy demonstrates notable development. While she remains a straightforward and demanding professional, she reveals her true nature as a caring and supportive figure, particularly in her role as a mentor to Mia. Her character shows that her initial abrasiveness is a defense against superficiality and a passion for authenticity in performance, not a personal flaw.

Regarding her abilities, Cathy is a highly accomplished performer and director on Broadway, which immediately establishes her as being at the top of her field. Her most notable ability, however, lies in her keen critical eye and her talent for creative direction and problem-solving. She can instantly identify a lack of emotion or chemistry in a performance, as she did with Leon. More importantly, she possesses the practical creative skill to solve major staging challenges, as demonstrated when she helps Mia figure out how to incorporate a legendary and dangerous maneuver into a classical ballet like Swan Lake.
