Little is known about Percy Proud except that he was a tire man for the Tuskegee Airmen's planes and the reason for the rivalry between Suga Mama and Gertie Dinkins since both seemed to have a crush on him back in World War II.
During the war, Suga Mama and Gertie were once best friends who used to dance together as partners against the Darnelle sisters in a dance contest held by Chick Robinson at the nightclub as entertainers for the soldiers. It was around that point when the Tuskegee Airmen walked in where Suga Mama and Percy Proud first met. It was love at first sight until Gertie tried to flirt with Percy. Despite the rivalry, Percy decided to dance with both girls as their partner against the Darnelle sisters and their own partner, Rubber-Lace Louie in the contest.
After Percy and the girls won the contest, the only thing left to do was for the girls to decide which one was going to leave with Percy. In the end, Suga Mama won through a coin-flip (later revealed by Gertie that Suga Mama cheated using a two-headed coin when she came back to get her purse and found it on the floor) and Percy and Suga Mama finally got married. Thus, began a 50 year grudge and the reason why Gertie, now one of Penny Proud's (Percy and Suga Mama's granddaughter) school teachers, decided to fail Penny on her homework including her latest essay on her hero, Hilary Clinton.
- Percy Proud bore a striking resemblance to his youngest son, Oscar Proud.
