Mr. "Grampa" TheCat, briefly known as Crud or as his "superhero" alter-ego Sprinkles, is the overarching antagonist of the Dog Man franchise.
He is Petey the Cat's abusive and selfish father who abandoned Petey and his mother, Grace, when the former was very young. Because of this, Grampa is considered the main reason into Petey's path of villainy. Ever since his reunion with Petey, Grampa has been considered the current World's Evilest Cat. He is one of the two current arch-nemeses of Petey, along with his former childhood friend Piggy, as well as the best friend of Big Jim and grandfather to Li'l Petey.
He is voiced by Stephen Root in the 2025 film, who also portrayed Unity and Reverend Amos Howell in Superman: The Animated Series, Frank in Ice Age, Mr. Fyde/Avacadwoe in The Epic Tales of Captain Underpants, Mildew in Dragons: Riders of Berk, Jim Hudson in Get Out, Professor Anders in The Legend of Vox Machina, Junjie in Kung Fu Panda: Legends of Awesomeness, Mayor Toadstool in Amphibia, and Martin Mertens in Adventure Time.

Appearance[]
He resembles a tall, tabby cat with a beard drawn with dots and hair coming out of his chin. He is usually seen wearing black transparent glasses with light-yellow specs. He has wrinkles below his eyes and five whiskers: two on his right side and three on his left. He is also usually seen with a limp when walking. In the movie, he is more aged, as his beard is gray and his glasses are also green.
Personality[]
Even as a young adult, Grampa is seen as a vindictive jerk and not a good person. As an old cat, he can be seen as grumpy and reluctant to do anything heroic.
History[]
Books[]
Before Dog Man[]
He had met and married a calico cat named Grace at an unknown date. Together, they had a baby named Petey the Cat. However, Petey's father was abusive to the other people in his family. One day, he had (presumably) somehow hurt Petey's tail. While Petey and his mom were at the hospital, Petey's father betrayed them and left, selling their house on top of that.
Dog Man: For Whom the Ball Rolls[]
On the night Petey was pardoned from Cat Jail, he had mentioned his dad to his son Li’l Petey. Then, while Petey was asleep, Li’l Petey went to Dog Man's house and asks his robot best friend 80-HD to go find his grandpa.
The next morning, 80-HD returns with Grampa, where he trespasses inside Petey's lab and starts destroying plates, where he said that it was Petey's fault because he put them up to high.
Later, Grampa measures the items in Petey's lab, and yells at Li’l Petey for making a mess with crayons while he was making a book for Flippy. As he sits down in a recliner, Petey comes with some seafood crackers. Grampa eats them up, and spits them out in disgust. As Petey walks away in anger, Li'l Petey tells Grampa that that was not nice, but Grampa says he doesn't care.
Later, Grampa walks in on his son and grandson working on a new invention called the Robo-Rat 2,000. Then, Grampa teases on Petey, until a news report comes on a television behind him, showing the Burgle Balls wrecking havoc and stealing from the stores inside the city. Petey and his son then leave to save the day, while Grampa leaves with a mischevious grin.
Afterward, Petey and Li’l Petey come back to the lab on the Robo-Rat 2,000, which had changed into the Ratterfly. On the way, they see Grampa in a moving truck. When they get back inside the lab, they notice that Grampa had stolen all of their possessions.
In Sarah Hatoff's News Blog at the end of the book, it says that Grampa was caught and was arrested and sent to Cat Jail.
Dog Man: Fetch-22[]
While in jail, Grampa had created sleep gas and put it in a balloon when Petey and Li’l Petey come to visit him.
In the visiting room, Grampa puts on a gas mask and pops the balloon, causing sleep gas to go everywhere, making Petey and Li’l Petey fall asleep.
When the gas cleared up, he had shaved his beard and drew his beard on Petey’s face. Then, he took off one of his whiskers and glued it on Petey. Then, he got a can of orange juice and took the lid off and glued it on the tip of Petey's tail. Then, he took off his glasses and gave them to Petey, making Petey look like him. He then took the wrapper of the orange juice can and sticked it on top of his tail, making him look like Petey, and he took Li’l Petey. He then told the warden that his 'dad' had fallen asleep, and soon he left Cat Jail, and put Li’l Petey in a garbage can.
Later, when Li'l Petey wakes up, he goes to Petey's lab, where Grampa is watching TV. There, the two have an argument about how Grampa is Petey, not him. Then, Grampa cooks Li’l Petey lunch, gives him much popcorn when Li'l Petey watches a movie, and more, which causes him to lose it.
Later, Sarah's poodle Zuzu came to Petey's lab and told Li’l Petey about the Fair Fairy and her army, who had captured all of Li'l Petey's friends. Hearing this, Grampa comes to the army and tries to join the Fair Fairy.
Later, Li’l Petey, Zuzu, and one of the female tadpoles in the Fair Fairy's army named Molly went to Dog Man's house and created an antidote to Supa Brain Dots. There, Li’l Petey blew up a balloon, while Zuzu went to the pond with the antidote. Li'l Petey then goes up to Grampa and tells him that an antidote to Supa Brain Dots was in the balloon, and when it pops, the tadpoles would lose their powers. He then tells Molly that she should hide in the pond so she doesn't lose her powers, to which Grampa overhears and tells the Fair Fairy about it, where she tells the tadpoles to go to the pond. There, Zuzu pours the antidote inside the pond, causing the tadpoles to lose their powers.
Then, the Fair Fairy and Grampa escape, where they accidentally get crushed by a falling cupcake sign (which Big Jim had mistaken for a cupcake). Then, two police officers notice and see that Grampa and the Fair Fairy had been captured. Then, 80-HD goes to Petey and takes off his disguise of Grampa's, and soon Grampa and the Fair Fairy are arrested and sent to Cat Jail and Old Lady Jail respectively.
Dog Man: Grime and Punishment[]
In Cat Jail, he had been at hard work on creating a new invention called the Motor Brain, which is a personality amplifier, which means that the wearer of the Motor Brain would become a beast with a personality of theirs. He then gets Big Jim, and tests it on him. It turns Big Jim into Snug, a very strong cuddly monster. After getting cuddled insanely, he accidentally falls into Big Jim’s secret escape room. Then, he asks Snug for his hat, and he puts it on, turning him into Crud, a strong eight-armed monster.
As Crud, he destroys the escape room and escapes through the escape chute and wreaks havoc in the town.
Later, Sarah Hatoff has a news report on Crud, and then she asks him why he's acting so evil, and he responds by saying that he wants to have a friend. That's when the head of the police department, Chief, sends in Dog Man and disguises him as an evil cat headed man. Then, Dog Man (dressed up as Cat Man) acts as a friend for Crud. When Crud sees him, he tries to destroy a nearby bookshop with his new buddy, however gets his tail tied up to a fire hydrant and then gets handcuffed. Then, Crud gets angry and tries to get rid of Cat Man, and accidentally taking off his cat helmet, revealing Cat Man to be Dog Man. Then, Sarah helps in trying to defeat Crud, until the the mayor of the city comes and arrests Dog Man, Sarah, Zuzu, and Chief (due to Dog Man's terrible behavior at Chief's award ceremony), and Crud escapes.
Later, Crud comes into a gift shop next to the third largest lunch bag in the world. He sees a sign in front of the lunch bag, which says to not spray the bag with Living Spray, which was now available in the gift shop. Then, Crud steals a can of Living Spray from the gift shop and sprays it on the bag. This turns it into Munchy the Lunch Bag. Then, Munchy wreaks more havoc, like ripping off and eating parts of buildings. Then, he gets thirsty and takes a smokestack from a building and uses it as a straw to drink nuclear waste. Then, Munchy gets fire in his mouth, and goes to the pond to dry his mouth out. There, the tadpoles from the previous book, now baby frogs (besides Molly, who is still a tadpole), are taking a lesson from their newly adopted father, Flippy. Munchy then kidnaps Flippy, while the baby frogs hide away.
Later, Petey, Li’l Petey, and 80-HD come to Munchy, and then stop Munchy with love by drawing things on him that they and the baby frogs love. Then, Munchy runs away.
Then, Crud comes back and takes the police car with the arrested good guys inside it. He then throws it away, however Flippy and Molly catch it. Then, Petey comes to Crud and tells him that he's going to forgive him. Crud, in shock, takes off the Motor Brain and tells Petey that he doesn't have a reason to forgive him, however Petey and Li’l Petey just leave and go back to the lab. Then, Grampa walks away in anger.
As he's walking, he throws away the Motor Brain, which Big Jim, who had been out trying to look for Grampa, catches, and put on, turning him back into Snug. Then, Snug sees Grampa, and chases him back to Cat Jail.
Dog Man: Mothering Heights[]
In Cat Jail, Grampa had created an evil scheme that needed a can of Living Spray and Cannery Grow. In order to get the ingredients, he goes back into the secret escape room and tries to open the escape chute, but gets punched by a mechanical hand when he presses the button. Big Jim, who was inside the escape room, tells Grampa that only he and his new robot he made (which is just a cardboard robot) can escape. However, Big Jim sadly can't figure out how to turn the robot on, and Grampa suggests to put a battery in it. While Big Jim went to get a battery, Grampa dismantled the robot and went inside it.
When Big Jim gets back, Grampa tells him that they need to go on a scavenger hunt for Living Spray and Cannery Grow. Them, they go out the escape chute.
When they go to a store, the store owner tells them that Living Spray was banned due to complaints and that the Cannery Grow factory was destroyed in Lord of the Fleas. After going to many stores, Big Jim tells Grampa he's ready to give up, but then, Sarah's news report on Petey comes up on a nearby television. It shows the inside of Petey's lab, where a bunch of cans of Living Spray and Cannery Grow are.
Once the two come to Petey's lab, Grampa accidentally slips on two sippy cups left on the floor by Li’l Petey and Molly, causing him to fall, which destroys the robot disguise. Then, Big Jim notices, and tries to stop Grampa after he took a can of Living Spray, but it ended up spraying the sippy cups. Then, they came to life, and Big Jim accidentally knocks down a can of Cannery Grow, and the newly sentient sippy cups spray themselves with it, causing them to grow in size and destroy Petey's lab. Then, the pink sippy cup swallows up Grampa and Big Jim.
Later, when Molly, inside a robot suit, destroyed the sippy cups, Grampa and Big Jim walk away, presumably back to Cat Jail.
Dog Man: The Scarlet Shedder[]
While Grampa doesn't physically appear in the book, he is mentioned by Petey and his mom in flashbacks.
Dog Man: Big Jim Begins[]
TBA
Movie[]
Past[]
Likewise in the books, Petey's father had betrayed Petey and Grace when the former was young by taking all their belongings in a truck and driving away, never to be seen again. This event caused Petey to become the villainous cat he is now.
Present[]
Decades after Petey's father's abandonment, Petey would tell his clone/son, Li'l Petey, how he had become the villainous cat he is now. Because of it, Li'l Petey sends a robot named 80-Hexotron Droidformigon, or 80-HD for short, to find Petey's father in hope that he had redeemed himself since then.
The next morning, just before Petey was about to go out and try to destroy Dog Man using a giant tank, 80-HD returns with Petey's father, who has now gone under the alias of "Grampa" in Li'l Petey's eyes. Grampa then makes himself at home by causing everything within the lab to be destroyed, such as plates or forks.
Later, when Petey tries to go out and destroy Dog Man again, Grampa comes out, saying he had spilled all their milk. Then, Grampa talks about how much of a "loser" Petey was when he was a child.
When a news report made by Sarah Hatoff comes on, saying that Dog Man and Petey were currently stuck on a statue of a gyro, Grampa wakes up from his nap to tell her through the TV that it was actually a statue of a cheesesteak.
Later, after Flippy the Psychokinetic Bionic Fish almost kills Petey and Dog Man using some Beasty Buildings, Li'l Petey comes in and asks Grampa, who was measuring all of the items in the lab, if he could help them. Grampa refuses to, leaving Li'l Petey to use 80-HD to stop Flippy.
After a climatic battle with Flippy, Petey and Li'l Petey come back to the lab to find that Grampa, once again, had stolen all of their possessions, put it in a truck, and drove away. However, Grampa leaves Li'l Petey's comics behind, showing he didn't care for Li'l Petey or his comics, depressing Li'l Petey even further.
Unlike in For Whom the Ball Rolls, where it is confirmed Grampa was arrested, nothing in the film confirms if he was imprisoned for his actions.

Trivia[]
- Him betraying his family could be a reference to Harold Hutchins' backstory, as his unnamed father and his mother divorced, and he moved to Nevada.
- Coincidentally, both Petey's and Harold's moms are named Grace.
- It was never shown what his evil plan was in Mothering Heights, just that it had something to do with Living Spray and Cannery Grow.
- It has been speculated and theorized that his true name is Peter, as his son's name, Petey, could be a nickname for Peter Jr. Another name that has been theorized is Ralph, due to what he calls his son and grandson, it could possibly mean that Ralph Jr. was originally Petey's name. However, the latest book has confirmed his real name is Roger.
- Him saying "Put me down, you nincompoopsicle!" in the movie is a reference to Toy Story 3, where Lotso says this when Big Baby was about to throw him in the garage except he says "idiot".
- He serves as a dark foil to Petey if he had never redeemed himself for many reasons:
- Both are extremely similar in appearance, with Dav even revealing that he draws Grampa in the same way as Petey and then simply adds some extra detail.
- Both of them betray their own children. Grampa's action was still worse, considering that brought Petey into villainy, but the action was still terrible.
- Both have many similar crimes, such as abuse, endangerment, murder, and many others.
