In "The Curse of the Ramsbottom" comic strip from the book Wallace and Gromit and the Lost Slipper, he is now a cyber-butler under the employ of Wendolene and her evil fiance, the cheese magnate Rhett Leicester with his army of gnomes.
Preston was built to be a friendly and helpful aid, but unfortunately, the end product was anything but. He is instead a pitiless thug and criminal, obsessed with wealth. He was willing to sink to the lowest depths to complete his agenda, willing to dispose of anyone or anything that interfered. He'd also be willing to brutally mince up sheep or humans to make more valuable dog food.
A portrait of him with his inventor indicates that perhaps at one time, Preston was the faithful companion he was designed as before his more sinister programming came to be.
He feels no loyalty towards Wendolene, whom he had forced into his sheep rustling scheme and had take part in his slaughter of the innocent animals. When she tried to stop him from attacking Shaun, he locked her up with the rest of them and did not hesitate to add her to the herd that was to be minced next.
After his destruction at the hands of Shaun however, he has been rendered totally harmless by Wallace and now acts as the more faithful pet he was originally programmed to be.
- Preston is named after the Lancashire town of Preston, which Nick Park comes from.
- Preston might be a parody of The Terminator due to being covered in skin and is an robot. Also both Preston's and first Terminator's fates were similar: Preston was crushed by a machine and the terminator was crushed by a hydraulic press.
- He resembles several different breeds of dog, but he mostly looks like an anthromoporthic presa canario.
- The Preston also shares similarities with the robots from the Simpsons episode, Itchy and Scratchy Land, as well as the animatronics from the indie survival horror game, Five Nights at Freddy's (though this can be considered merely coincidental as the game was released more than a decade after A Close Shave).
- Apart from growling and roaring, Preston is silent.
- Unlike Feathers McGraw, who threatened to kill Wallace, Preston has killed many sheep very inhumanely, and because of this, he is probably the darkest character Aardman has created, alongside Mr. Arnold Hugh from Stage Fright, Mrs Melisha Tweedy from Chicken Run and Piella Bakewell from A Matter Of Loaf and Death.
- In fact, Preston shares quite a few notable traits with Melisha Tweedy from Chicken Run: Both are paired up with fearful, subordinates, one an equally intelligent but benign female wool farmer called Wendolene Ramsbottom, the other, an equally cruel but less intelligent male egg farmer called Mr. Willard Tweedy. Both Preston and Melisha are disappointed with the current business they work in, For Preston's case is wool-making, and For Melisha Tweedy's case is egg-counting, and aspire to become rich by butchering up their livestock using vast machines to mass-produce food, and crafting their public image as sweet and friendly, For Preston's case is mutton-flavored dog food, and For Melisha Tweedy's case is chicken pot pies. Melisha and Preston both had their former subordinate rise against them, but their species are different, For Preston's case is a cyber canine and is very silent, and For Melisha Tweedy's case is a human and is very capable at communicating in English language.
