Prior to the events of Kingdom Hearts, Pongo's world was destroyed. With his wife Perdita, he somehow found his way to Traverse Town. In addition, the ninety-nine puppies which Pongo and Perdita looked after had been thrown about to other worlds in the chaos.
The story of the dalmatians' plight managed to spread very quickly amongst the residents of Traverse Town. Leon was especially concerned about the matter, and brought it to Sora's attention. Throughout his journey, Sora found the dalmatian puppies and sent them back to Pongo and Perdita in Traverse Town. Pongo and Perdita were very grateful, and offered Sora gifts for his journey as more and more dalmatians were returned to them.
Pongo is a typical dalmatian with white fur that is speckled with black spots. He wears a red collar, as do all of his sons, while his wife and daughters wear blue collars.
Pongo is the ideal father. He is very caring of his wife and pups, and in Kingdom Hearts, his anguish at losing the latter is very pronounced.
Pongo's appearance in Kingdom Hearts is based on his look in Walt Disney's 101 Dalmatians. That film was in turn inspired by the book The Hundred and One Dalmatians by Dodie Smith, which was published in 1956. Although Pongo was essentially characterized the same in both the film and the book, he was married to another dalmatian (named Missis) in the original book, and by the end of the story found himself the father of ninety-seven puppies, as two of the total one hundred and one were adult dogs who lived with Pongo's family, away for Cruella De Vil.
