Uncle "Larry" Grandpa is the main Protagonist of the series Uncle Grandpa. He is everyone in the world's uncle and grandpa at the same time. He goes around helping children who have usually never heard of him. The children do not appreciate his help at first, but then realize the great adventures they have with him. He is voiced by Peter Browngardt.

Physical Appearance

He is a short, older adult who wears black overalls with rainbow shoulder straps, a white collar shirt, and a blue propeller hat that sits on top of his head (which has a prominent lump). He also has a brown mustache, with a tooth sticking out of it, and a large chin. He also wears a talking red fanny pack, known as Belly Bag.


Uncle Grandpa is very cheery, and is for the majority of the time happy. He likes to help others, especially his friends, and mainly helps kids around the world. Uncle Grandpa seems to have a different array of magical powers, that range from time travelling to making clones of himself. Uncle Grandpa is always using these magical powers, with the assistance of his Belly Bag of course. At first Uncle Grandpa's plans seem dumb, but in the end his plans work out in his favor and he (not) always gets the job done. 

Uncle Grandpa's Room

Uncle Grandpa and Belly Bag's Room is a real zany room filled with lots of neat toys and accessories that Uncle Grandpa periodically collects over time. The two sleep in Uncle Grandpa's race car bed (Belly Bag is usually strapped to a pillow, as seen in Bottom Bag). There's usually a gumball machine a hot dog poster and a sword seen in any episode that features their room. His bedroom is the most zaniest bedroom in the entire RV.


Mr. Gus

Mr. Gus is Uncle Grandpa's bodyguard. He is always there to look out for him and is supposed to do whatever he wants him to do. Mr. Gus doesn't always agree with what Uncle Grandpa says and does, but he is always there for his Uncle Grandpa when he needs his support the most.

Pizza Steve

Uncle Grandpa and Pizza Steve are best friends. Uncle Grandpa always believes the lies that Pizza Steve tells him, no matter how ridiculous they may be. Even when it has already been proven to Uncle Grandpa that Pizza Steve is wrong, he still tends to believe everything he says. Pizza Steve has on occasion gone out of his way to help Uncle Grandpa, but he can also exhibit selfishness and lack of care for his Uncle and Grandpa. Regardless of how Pizza Steve may act, Uncle Grandpa will always love him and hold him in high regard.

Belly Bag

If Uncle Grandpa ever needs anything, Belly Bag is sure to have it. All Uncle Grandpa needs to do is just reach into Belly Bag and take it out. Uncle Grandpa and Belly Bag have been together ever since they were babies. The two of them are great friends. They may not always see eye to eye, but unlike Mr. Gus who will tell Uncle Grandpa straight up, Belly Bag takes a passive approach to his constructive criticism of Uncle Grandpa's actions.

Giant Realistic Flying Tiger

Giant Realistic Flying Tiger is one of Uncle Grandpa's best friends and also acts as a form of transportation for him when he is not using the RV. Whenever him and the others get into some serious trouble, she is usually the one to come and clean up their mess.

Tiny Miracle

Tiny Miracle is Uncle Grandpa's robotic assistant and is always happy to help him. He was first seen helping Uncle Grandpa in the episode "Tiny Miracle the Robot Boy". Uncle Grandpa needed help opening a jar of burgers and Tiny Miracle helped him. After that, he needed his help again with cleaning up the mess he made. He helped him again in the episode "Big in Japan" by playing the organ at Mr. Gus's funeral. Tiny Miracle also helped Uncle Grandpa when he wanted to watch TV while on the new couch in Big Trouble for Tiny Miracle, along with other backbreaking tasks the gang made him do.


Uncle Grandpa and Frankenstein both have a good connection with each other. In Tiger Trails, Uncle Grandpa needed some Frankenstein Juice to pour on the ground to revive several dead pets and Frankenstein was happy to oblige. In Body Trouble, Frankenstein gave his body to Uncle Grandpa when he needed a new one to show off to Belly Bag.

Charlie Burgers

Uncle Grandpa helped out Charlie just like he would do with any kid he helps out. At first Charlie was confused to see someone like Uncle Grandpa, but he grew to like him just like the rest of the gang. Uncle Grandpa and the others decided to help Charlie in his time of need and later on in Charlie Burgers, he sacrificed his ball to save everyone from going into the black hole. Charlie helped Uncle Grandpa when his nose was puffed up like a beach ball in Uncle Grandpa Retires and Uncle Grandpa thanked him.

Beary Nice

Uncle Grandpa and Beary never really interacted in any episodes. In Haunted RV, Uncle Grandpa was trying to get Beary's attention when they met him as if they knew each other for a while. Beary may live in the RV as he was found throughout the episode.

Hot Dog Person

Uncle Grandpa and Hot Dog Person never really interacted in any episodes. Along with Beary, Hot Dog Person may live inside the RV as he was found with Beary at the end of Haunted RV. They also interacted in Exquisite Grandpa


Samantha is Uncle Grandpa's laser hammer which he uses in various episodes such as Locked Out and Sick Bag. Samantha is usually stored inside Belly Bag so he can use it any time he wants.

Aunt Grandma

Uncle Grandpa's nemesis who tries her best to make Uncle Grandpa obsolete at helping children. She has taken the role of "Aunt Grandma" and the way she usually helps kids is to solve their problems at the source instead of going on an adventure. Uncle Grandpa and Priscilla hold a negative relation towards each other since Uncle Grandpa failed to help her in the 90's, Uncle Grandpa was trying to teach her that all work and no fun was no way to live a life. The two even had a huge fight after Priscilla snapped at Uncle Grandpa.

Evil Wizard

In Uncle Grandpa Retires, Evil Wizard was trying to sabotage the RV by trying to pop Uncle Grandpa with spiked wheels when he was still a wheel, Uncle Grandpa used a nail file on his wheels, much to the wizard's dismay. Uncle Grandpa also gave him the file for his nails. Evil Wizard later on teased Uncle Grandpa during the race, while Uncle Grandpa was trying to help Evil Wizard by telling him to look out for the ducks in front of him.


Uncle Grandpa helped Xarna when he got the gas for her motorcycle and saved her from being forced to marry Wallace T. Germbug. He gave Xarna a tricycle when she was unable to get gas for her motorcycle and she thanked him for it.

Crazy Baby

Uncle Grandpa is the main cause to Crazy Baby's existence. In Driver's Test, When Mary couldn't shift into reverse while parallel parking, so Uncle Grandpa tried to help and accidentally unleashed Crazy Baby. into the world. Crazy Baby is easily angered and doesn't seem to like Uncle Grandpa very much.

Abilities and Traits

Uncle Grandpa has the ability to make clones of himself. His clones only appear without showing how he made them. So it is unknown how he does it. Uncle Grandpa has shown to had the ability to remove parts of his body and make them move on their own. He has removed his head from his body and seems to have a large variety of other heads and bodies of himself in his room. He has also been seen removing his nose in the episode "Belly Bros" and has been seen with a drawer full of noses in his room too. Uncle Grandpa has also been shown to have wizard powers in the episodes "Belly Bros" and "Tiger Trails". Uncle Grandpa will put on a wizard hat and cloak, and can make lightning come out of his hands.

Bubble Grandpa

Bubble Grandpa

Bubble Grandpa is Uncle Grandpa's evil ocean doppelganger as seen in The Little Mer-Tiger. Bubble Grandpa is one who'll bash on anyone if they deny his demands, he's one to believe that all sea creatures should live in the sea and without legs. He has an evil companion similar to Belly Bag and is quite resourceful to Bubble Grandpa. Bubble Grandpa lives in an underwater cave that looks like the RV in the Pacific Ocean, he's formally the ruler of the sea after being turned into a sea snail. As well as Uncle Grandpa, he yields a magical lightning hammer to shape-shift someone into a different creature just like how Uncle Grandpa yields a magical laser hammer. Bubble Grandpa looks like Ursula from The Little Mermaid.
