Jasper enjoys drinking alcohol, playing darts, and watching What's My Crime? with Horace. He is the taller of the two. Horace is shorter, fatter, and loves sandwiches and cakes. They are hired to dognap Pongo and Perdita's 15 Dalmatian Puppies to be used in making Cruella's fur coat. Neither one seems to be very smart, but Horace appears to have more insight, and is often shown to correctly guess what the Dalmatians' plans are. Jasper, however, quickly rejects these ideas in favor of his own believing that the dogs are not smart enough to evade them. Although Jasper and Horace carry out Cruella's deeds, they do not enjoy it and do it only for money. In the second film, the duo finally stand up for themselves, reform, are pardoned for their part in stealing the puppies and open up a clothes corporation.
One Hundred and One Dalmatians
In 101 Dalmatians, the two sneak into Roger and Anita's house, by attempting to pass themselves as repairmen from the Electric Company (Kanine Krunchies deliverymen in the sequel and the musical version.) Nanny refuses to let them in since Roger and Anita are gone but the vile men force themselves in, and Jaspar toys with Nanny up in the attic, while Horace steals the puppies, and the two transport them to Cruella's former home, Hell Hall. Soon after, the dognapping is covered by the newspapers, causing the two to attempt to back out. They call Cruella and ask for their payment, but she refuses to pay until the job is done.
At Hell Hall, the henchmen laze about watching TV and eating, along with the stolen puppies and 84 bought puppies. This is where their potential kindness comes into play, as they allow them to watch TV but tell Lucky to move so they can see "What's My Crime?". Eventually, an incensed Cruella arrives and tells Horace and Jasper that she "wants the job done tonight", or she'll report them to the police. Though Jasper notes that the puppies were not big enough for the amount of coats Cruella apparently desires, she decides to settle for what they can get and leaves. While they are watching the television show What's my Crime?, the puppies are rescued by Sergeant Tibbs. After the show has ended, Jasper and Horace argue over whether or not Jasper skins and Horace kills them and vice-versa but are taken off track of arguing when they over-hear a sound from the door.
Jasper and Horace then notice that the puppies have escaped, and begin a search of the house. Eventually, they are able to corner the puppies in a room. Before they can kill the puppies, Pongo and Perdita arrive and fight Jasper and Horace. While the puppies escape, Horace is knocked into the fireplace by Perdita and Jasper gets his pants pulled down by Pongo. Both are buried underneath the ceiling when it collapses.
After escaping the debris, they track the dalmatians to a farm building via their footprints. After being attacked by Captain, they realize that the dogs have already left the building. They attempt to head off the dogs, but the Dalmatians elude them by traveling up a frozen river.
A few days later, Jasper and Horace meet with Cruella on the road. Though they attempt to quit, Cruella forces them to continue. She points out that the Dalmatians tracks lead to a nearby village called Dinsford. In Dinsford, Jasper and Horace search for the puppies. Horace points out some "Labradors", suggesting the possibility that the dogs disguised themselves. Jasper blows off the idea and calls Horace an idiot before smacking him in the head.
When the Dalmatians are discovered to be hiding in a van heading for London, the two pursue the van in their truck. Jasper makes a plan to ram the van into a ravine, but Horace gets scared and pulls out the steering wheel causing the truck to slide down the mountain off aim and ends up hitting Cruella's car. Cruella suffers a breakdown, cursing their incompetence, but Jasper simply tells her to shut up finally getting the courage to stand up for themselves. Based on the events of the sequel, it can be presumed that they and Cruella are imprisoned, although this film does not show what happens to them.
The live-action remakeIn the live-action remake produced by John Hughes, Jasper and Horace were portrayed by Hugh Laurie and Mark Williams. They were inspired from Harry and Marv from the first two films of Home Alone (which were incidentally produced by the same producer). Here they are both skinny and aren't implied to be related. They are still very similar to their animated counterparts, though they are depicted as much more ruthless characters, and never reform. Jasper is also shown to be a little bit smarter in this version. They actually seem to enjoy animal cruelty, even deciding to take over taxidermist Mr. Skinner's job of killing and skinning the puppies. At the end, tired of all the misfortunes they had endured after kidnapping the puppies and accidentally letting them escape, they allow themselves to get arrested and end up being sprayed by a skunk.
Unlike their counterparts in the animated version, Jasper and Horace aren't seen in the sequel, 102 Dalmatians, which assumes that they may be still locked up.
101 Dalmatians: The Series
In 101 Dalmatians: The Series, they are the "H. and J. Concepts" company and are employed by Cruella to do her dirty work. This involves delivering ransom notes and going through Anita's trash. Unlike the movies, they have American accents and dressed differently than they did before (due to the series being set in America).
101 Dalmatians II: Patch's London Adventure
In 101 Dalmatians II: Patch's London Adventure, Jasper and Horace are the teritary antagonists. Cruella pays their bail money so that they can round up the puppies for her artist friend Lars to use as canvases. They passed themselves as Kanine Krunchies deliverymen, and have succeeded into luring the puppies into the truck. They also had Nanny tied up in a well. However, when Lars, Cruella's artist friend, refuses to kill the puppies, Cruella decides to finally get her spotted fur coat. After Cruella, Jasper, Horace, and Lil' Lightning (Thunderbolt's envious sidekick) are thrown into a river, all four are arrested; however, Horace and Jasper are turned loose after they, finally having had enough of Cruella, confessed to Nanny, Roger and Anita that it was their boss who told them to get the puppies and is behind the dognapping. After they are both pardoned, they apparently go straight and obtain their own line of sundresses.
Jasper and Horace make a cameo in the Bonkers episode "The 29th Page" at a prison line-up.
The two brothers make a cameo appearance in the House of Mouse episode "Suddenly Hades", during the Hades Heating advertisement at the end of the show. The duo also appeared in the film Mickey's House of Villains.
Jasper and Horace make a small amount of appearances in merchandise for the park and a few live appearances. Most of the merchandise including them have to do with Disney Villains although they have been in some Disney Cruise Line material.
Sorcerers of the Magic Kingdom
On Main Street USA, Horace and Jasper are forced to work for Cruella in an attempt to find the legendary Crystal of the Magic Kingdom as she threatened to murder them if they refuse to follow her every demands. Upon learning that Pongo has contacted the local dogs to guard the crystal, Cruella sends Jasper and Horace to capture and eliminate them. Jasper creates several traps to capture the dogs, and Horace takes them to Cruella's lair. When the park guests arrive, they defeat Jasper by trapping him in one of the dog traps. The guests then heads to Cruella's lair, where the villain ordered Horace to eliminate the captured dogs. Before he can, the guests arrives and unleashes the dogs. The dogs then attack Horace, giving the guests a chance to go after Cruella.
