Prince Pompadore, also known by his nickname Pompa, is the crown prince of the little kingdom of Pumperdink in the Gillikin Country of Oz, being the son of King Pompus and Queen Pozy. After adventuring with Kabumpo the Elegant Elephant, Pompa married Princess Peg Amy of Sun Top Mountain. (Kabumpo in Oz)
Pompa and Peg had a daughter named Pajonia. The royal family and some of their retainers were kidnapped by the wicked princess Faleero, but were rescued by Kabumpo and his new friends Randy and Jinnicky. (The Purple Prince of Oz)
Pompadore was one of many Ozian intellectuals who were mesmerized by the Wishing Horse Chalk into thinking that Skamperoo was the rightful Emperor of Oz. (The Wishing Horse of Oz)
Later, when Kabumpo goes missing from the court of Pumperdink, Pompa goes in search of him, resulting in further adventures. (Prince Pompadore in Oz)
