Proud Heart's original design in 1985 showed an orange-tan body with peach muzzle and inner ears; merchandise such as a UK-only stuffed animal had a very light yellowish-orange body with a white muzzle, inner ears, paw-hearts & palms.
In 1991, the first relaunch of the Care Bears temporarily changed Proud Heart into a white bear with an American flag as a tummy symbol.
In the 2002 revamp, Proud Heart returned to being a cat, but had a turquoise body, white on all four paws, muzzle, tail-tip and inner ears, plus a pink nose.
During the original DiC animated series, Proud Heart would usually end her sentences with a typical cat sound such as a purr or screech, while in the follow-up Care Bears Family series, she tended to to enunciate her "er" sounds. A staunch "purrfectionist" by nature, she is characterized as being single-minded and practically obsessed with order and cleanliness, especially in her garden, which often puts her at odds with Playful Heart Monkey. Her credo is to remind everyone to do their best in everything.
The Care Bears Movie
Along with the rest of the Care Bear Cousins, Proud Heart Cat first appeared in The Care Bears Movie as a male, where he is called upon by Brave Heart Lion to help their new friends defeat The Spirit, and stop it from removing all caring from the world. He is among the characters present at the end of the movie that helps seal the villain away once and for all, and is made an honorary member of the Care Bear Family.
Care Bears TV series
Proud Heart's first real appearance in the series involves him planning a party for the Care Bears, only to have the cake stolen by Playful Heart Monkey. The two must learn to put aside their differences to help a girl named Millie who believes she has bad luck. Later, he was among the Care Cousins who helped stop Professor Coldheart from covering a city park in cement. .
When a drought threatened a town on Earth, Proud Heart and Swift Heart Rabbit joined the Care Bears in investigating, and were able to break their friends out of a cave using a combined Care Cousin Call. . Later, when a group of children became lost at sea during a storm, he, along with Cozy Heart Penguin, Loyal Heart Dog, and Gentle Heart Lamb, board the Cloud Clipper to save them, with Proud Heart at one point taking the wheel.
Care Bears Movie II
Proud Heart has a minor appearance in the second Care Bears feature film, where the origin of the Care Bear Family is explained for the first time, and tells of how he and his fellow Cousins arrived in the Forest of Feelings.
Care Bears Family TV series
Proud Heart is a main character in the episode "Home Sweet Homeless", where his prize garden is ruined by Playful Heart Monkey's antics, and a fountain sent to him by a secret admirer turns out to be a trick by Mr. Beastly to flood to entire Forest of Feelings.
When this incident causes the Care Bear Cousins to move in with the Care Bears at Care-a-Lot, tempers begin to flair between the two groups, which forces Proud Heart and Playful Heart to work together to convince Mr. Beastly to fix the problem.
Proud Heart is one of nine Care Bear Cousins who received a redesign for their 2003 re-launch toyline. Her appearance is more substantial than some of the others, with her fur color changed from orange to turquoise with white "mittens" on her hands and feet, white inner ears, a white spot at the end of her tail, and a pink nose. This version has not appeared in any form of 2000's Care Bears media aside from merchandise.
Proud Heart makes only one appearance in Star Comics' Care Bears series in issue 3, "Blue Who". When a group of aliens called The Gloomies turn the Forest of Feelings and everyone in it blue, Proud Heart is among the affected and loses his cheerfulness but later gets it back.
- Proud Heart Cat is the only character to be mentioned by name in two songs from the original series: "When You Care, You're Not Afraid to Try" from the first movie ("We're calling on the proud hearts to come and follow me"), and Flying My Colours from the second film ("Proud Heart Cat doesn't have a lot to say...").
- Despite the stereotype of dogs and cats not getting along, Proud Heart and Loyal Heart Dog are actually quite good friends, with the latter even giving him a flower as a pup in Care Bears Movie II: A New Generation.
- While Proud Heart was initially introduced as an orange male in 1985, a marketing decision was made to depict the cat as a turquoise female when the series was revamped in 2000; no indication was given within the films or either series that Proud Heart has any gender identity beyond what is depicted. (Some fans do like to envision the character as genderqueer, transgender, or gender-fluid, however.)
