SpongeBob's relatives

This article is a list of the members of SpongeBob SquarePants' family tree, listed in the order of their first (or only) appearance or mention.
Image	Name 	Voice actor 	Description
 	Harold and Margaret SquarePants 	Tom Kenny and Sirena Irwin	SpongeBob's parents, first seen in the episode "Home Sweet Pineapple". Oddly enough, they bare more resemblance to actual ocean sponges than SpongeBob himself.
 	Grandpa SquarePants 	Tom Kenny 	SpongeBob's paternal grandfather is first mentioned in "Rock Bottom" and appears in SpongeBob's mind in "The Sponge Who Could Fly". He is known for his wise sayings, which include "If we were meant to fly, we'd have propellers on our backs," and "Never run for a bus, especially one that's going up at a 90 degree angle."
 	SpongeTron 	Tom Kenny 	SpongeTron is a robot descendant of SpongeBob who lives during the 41st century, seen in the episode "SB-129". When Squidward Tentacles arrived in the future, he shortly met SpongeTron and some of his clones in the kitchen area of the Krusty Krab. SpongeTron is visually identical to SpongeBob, but his legs are rockets, which allow him to hover over the floor. He is also able to pull his ties to make an robotic arm come out of his hat, holding a brick to drop. SpongeTron's best friend is Patron (a two-headed descendant of Patrick).
 	SpongeTrons X, Y & Z 	Tom Kenny 	Pictured here are three clones of the above-mentioned SpongeTron. According to SpongeTron himself, he has 486 clones, 1 for each letter of the future alphabet.
 	Primitive sponge 	Tom Kenny 	This unnamed primitive sponge is SpongeBob's earliest-known ancestor, seen in the episode "SB-129" when Squidward travels back to prehistoric time.
 	Grandma SquarePants 	Marion Ross 	SpongeBob's paternal grandmother, first seen in the episode "Grandma's Kisses".
 	Larry 	N/A 	One of SpongeBob's cousins, mentioned in the video game SpongeBob SquarePants: Operation Krabby Patty. When SpongeBob wakes up and tries to find Gary, Plankton uses a tape recorder to tell SpongeBob he has stolen his pet. He mistakenly calls the snail "Larry" at first, causing SpongeBob to think that Plankton has kidnapped his cousin Larry.
 	Sherman "Sherm" SquarePants 	N/A 	Sherman SquarePants is a sometimes-mentioned uncle of SpongeBob's, though he has never made a physical appearance, instead only being seen in photos. He is first mentioned in "Krab Borg" and is seen in a photo in "Pest of the West".
 	SpongeGar 	Tom Kenny 	SpongeBob's caveman ancestor is more curious and smarter than his primitive ancestor. He is also more advanced than the Primitive Sponge because he has developed clothes, a language system, domestication, and a curiosity for new discoveries, such as cooking food.
 	BlackJack SquarePants 	John DiMaggio 	BlackJack is SpongeBob's muscular cousin who is the main antagonist of the episode "BlackJack". In the episode, SpongeBob receives a note from his cousin BlackJack, saying that he is going to pay him a visit. SpongeBob is shown to greatly fear BlackJack, because BlackJack always picked on them when he was little, and was even arrested for littering. Fortunately, when SpongeBob does confront BlackJack at the end of the episode, it is revealed that BlackJack is no bigger than Plankton and thus cannot actually harm SpongeBob.
 	Captain Blue SquarePants 	Garnett Sailor 	Uncle Captain Blue is a retired police captain who is SpongeBob's uncle, seen only in the episode "BlackJack". He is quite lazy, and enjoys drinking Clam Tomato Chowder Juice, listening to country music on his old record player, and talking on a CB radio.
 	Stanley S. SquarePants 	Christopher Guest 	Stanley, who appears only in a self-titled episode, is SpongeBob's accident-prone cousin who destroys everything he touches. Uncle Sherm sends Stanley to SpongeBob's house to see if he can take care of him. Stanley then goes to the Krusty Krab because he is jealous of SpongeBob having a job.
 	SpongeBuck SquarePants 	Tom Kenny 	SpongeBuck is SpongeBob's ancestor who appears in the episode "Pest of the West". He was an old Western hero who lived in Dead Eye Gulch and sometimes hung out at the Krusty Kantina. He rescued Dead Eye Gulch from being taken over by Dead Eye Plankton (Plankton's ancestor) in 1870, the "Wild West" period. He was best friends with Pecos Patrick, the cowboy ancestor of Patrick.
 	SpongeBrian, SpongeKevin, and SpongeCarl	N/A 	These three nephews of SpongeBob appear in the comic "My Nephews Are Coming to Visit". In the story, they come to Bikini Bottom to visit their uncle SpongeBob. However, they find everything boring in the city and begin to irritate the inhabitants. Ironically, though, they enjoy Squidward's hobbies. They are parodies of 's nephews, . These are the only SquarePants family members who are confirmed to be non-canon.https://twitter.com/VincentWaller72/status/745816538754617344
 	Todd SquarePants 	N/A 	Todd is SpongeBob's long-lost, very slobby cousin, who appears only in the read-along book Story Reader: The Never-Ending Stay.
