Patch

Patch is the most prominent of the Dalmatian puppies in 101 Dalmatians. He is a small puppy with a large black patch over one of his eyes, hence his name. He feels lonely and left-out oftentimes with his family, thinking that he's just one of the famous 101 dalmatians, and longs for a chance to become separate and leave the shadow of his brothers and sisters. He is a good pup, very adventurous, bold, and strong-minded.

Today, Patch is commonly used alongside Cruella De Vil as an icon to represent their respected films in merchandise and crossover material.

Personality
Patch may be the most mischievous of the 99 puppies. Like his siblings, he is playful and cute, but he can get rather wild, often fantasizing about mauling the villain Dirty Dawson from the Thunderbolt television series. He looks up to his father as his role model especially after he was rescued by them. When attacked by Jasper and Horace, Patch was the only one of the puppies to attempt to fight back. He also holds a small rivalry with Lucky. He and Lucky are very similar in personality, however there are a few differences. Lucky is confident and arrogant as apposed to Patch who is insecure and humble. Lucky is apparently considered the favorite of the pups, this could be part of their rivalry.

One Hundred and One Dalmatians
Patch is first seen in the film watching television with his brother and sisters. Patch seems to be addicted to the TV show Thunderbolt and interacts with it. After Patch and the puppies are put to sleep they are kidnapped by Jasper and Horace, henchmen to Cruella De Vil who seeks their skin to create coats. Patch's parents journey to save their puppies and Patch escapes with the rests. When needing to get past Cruella, Patch and his brother Lucky get into an argument and push each other in a fireplace and are covered in sot. This gives his father the idea to disguise themselves. Eventually they returned and Patch is safe at home with his family.

101 Dalmatians
Patch is not an official character in the movie (though he appeared on some tie-in merchandise). However, a puppy resembling him can be seen at times, and he was included on the original VHS cover to the film.

101 Dalmatians: The Series
Patch also appeared as a secondary character in the TV series, where he was designed to match his appearance in the original book. For the series his personality was given to Lucky. In the series, Patch was loyal to his family and friendly with all the puppies. For unknown reasons, he wears a rope tied around his neck as opposed to a collar. In early production, he was going to be a main character, as well as his sister, Penny, however, Disney didn't want too many main characters, and so Patch became an extra character while Penny was dropped. Patch was also going to be more mischievous and protective over Cadpig; however, that was dropped as well.

Episodes in which Patch has speaking roles include "Our Own Digs," "Prima Doggy," "Citizen Canine," "Close But no Cigar," and "Shrewzle Watch."

Contradictions
As seen in the original One Hundred and One Dalmatians, he is one of the normal shaped and average looking pups, he wears a red color and one of his ears are completed dyed in pitch black. However, in the series, this concept was changed, his appearance resembled that of Rolly's, larger and fatter. And replacing his red collar, a rope tied around his neck. But again, his original appearance was again featured in the sequel, 101 Dalmatians II: Patch's London Adventure.

House of Mouse
Being the most iconic puppy, it is no surprise that Patch made dozens of seemingly obvious cameos in House of Mouse. In "Pluto Saves the Day", he and Rolly were part of an all dog band and performed "Everybody Wants to Be a Woof" and defeated Pete with the band and Pluto at the end. In the episode "Ask Von Drake", Patch can be seen with his siblings and father during The Ludwig Von Drake Song.

Kingdom Hearts
If one were to look carefully for details in the game and strategy guide, Patch is Puppy #5.

101 Dalmatians ll: Patch's London Adventure
Patch is also the main character in the 2003 sequel 101 Dalmatians II: Patch's London Adventure. Patch feels unimportant being that he is said to be just another one of the 99 puppies. Patch runs away and meets his hero Thunderbolt. They spend time acting like heroes around London but when Cruella De Vil returns and captures his siblings, Thunderbolt and himself, he learns Thunderbolt is just a television star and all the powers and villains on TV were fake. Patch uses his wits and boldness to save his family and defeat Cruella De Vil with the help of Thunderbolt. Patch reunites with his family and given the attention he awaited.

Electric Holiday
In the animated short, Patch makes a brief cameo during the end credits, gnawing on Cruella's design sketch.
