George White, affectionately called Papa, is the husband of Mary (Mama) and father of Kitty White (Hello Kitty) and her twin sister Mimmy. The family resides in a London suburb. Papa typically wears brown pants, a blue collared shirt with a red tie, and black eyeglasses; older media sometimes depicted him with a smoking pipe. For casual occasions, he chooses a dark green jumper, blue jeans, and brown shoes, while formal events call for a navy blue shirt and brown pants. Like his family, he is often drawn without a mouth, though some portrayals include one. He stands approximately twice as tall as his daughters.

Papa possesses a calm, easygoing nature marked by dry humor. When sad, he grows quiet. He balances hard work and seriousness with occasional clumsiness and a capacity for laughter. Despite his job, he prioritizes family time. His personality is characterized as slightly less friendly but more childish and fatherly than Grandpa.

Daily life finds Papa engaging in routine activities with his children, such as taking them downtown for errands. During these outings, he teaches them about household appliances, explaining their role in creating a warm, cozy home. He emphasizes respect for workers like postal carriers, noting the challenges they face delivering mail in all weathers. He responds supportively to his daughters' aspirations—Kitty's desire for a bookstore and Mimmy's for a flower shop. These interactions reveal his role in guiding their understanding of the world.

His birthday is June 3rd, making him a Gemini. Specific episodes highlight family celebrations for this occasion, reinforcing his centrality within the family. Papa features consistently in the animated segments of the Japanese television series "Kitty’s Paradise" (1999–2011), interacting with extended characters like Moley the mole and Birdie/Sally.
