George White, known as Papa, is the anthropomorphic white cat father of Hello Kitty (Kitty White) and her twin sister Mimmy White, and the husband of Mary White (Mama). He typically appears in brown pants, a blue collared shirt with a red tie, and black eyeglasses. Older portrayals sometimes feature him holding a smoking pipe. He stands roughly twice as tall as his daughters. For casual occasions, he wears a dark green jumper and blue jeans with brown shoes, while formal events call for a navy blue shirt and brown pants. Like his family, he is usually drawn without a visible mouth, though some depictions include one.

Papa possesses a dry sense of humor and generally maintains a calm, easygoing manner. He is a hard-working and serious professional employed at a trading company where he uses a computer, yet he also displays a slightly clumsy and occasionally silly side. When sad, he becomes quiet. His personality is less overtly friendly but more fatherly and childish compared to Grandpa.

He balances his responsibilities with prioritizing family time, demonstrating warmth and attentiveness as a parent. He drives the family car and engages in activities with his daughters, such as presenting Hello Kitty with her pet Persian cat, Charmmy Kitty, on her birthday and gifting her a goldfish on another occasion. He also welcomes his daughter Mimmy's friend Robert to the family property.

His birthday is June 3, making him a Gemini. In extended media like games, he often appears in family-oriented or domestic scenarios, visiting locations where Hello Kitty and Mimmy reside, and interacts with home-related objects such as antique furniture, books, and comics.
