- “You idiots! You... You fools! Oh, you imbeciles!”
- ―Cruella to Jasper and Horace
Jasper and Horace are Cruella De Vil's bumbling henchmen and the secondary antagonists of the first 101 Dalmatians film.
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 intelligent, 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 dogs couldn't possibly be that intelligent despite already showing that they indeed are. Although Jasper and Horace carry out Cruella's deeds, they do not enjoy it and only do it only for money.
Before the Isle of the Lost
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 Jasper 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 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 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 first thing in the morning," or she'll report them to the police. Though Jasper notes that the puppies were not big enough for the number of coats Cruella apparently desires, she decides to settle for what they can get and leaves. While they are watching the 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 overhear 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 tripped 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 while the two just sit there sulking, but Jasper simply tells her to shut up finally getting the courage to stand up for themselves and they are then later imprisoned with cruella obviously taking a plea bargain and instead having her sentence reduced to probation for her crimes.
