Well, I bought the salon from my mom, and Emma's...a teenager now, and believe it or not, she's actually going to Degrassi just like we all did. It's like some kind of weird deja vu.When, rather than using Spinoff Babies (the main characters of an older series being made younger) you instead make a show about the descendants of people from the original premise. Sometimes evolve out of a Kid from the Future. May overlap with both Generation Xerox and Legacy Character, but can also exist independently of both tropes. Sub-Trope of Changing of the Guard. The current heroes may become Kid Hero All Grown Up. Popular Fan Fic device, especially if there are canonical descendants.

Anime & Manga
- The Japanese have done a few anime series about the fictional descendants of The Shinsengumi, including Tobe! Isami (Soar High! Isami) and Kidou Shinsengumi Moeyo Ken.
- Japan does this a lot, actually. For example, JoJo's Bizarre Adventure has a different "JoJo" for each arc, but most/all are blood relatives one way or another (to exemplify: Jonathan is grandpa to Joseph, who is grandpa to Jotaro, who in a subversion, is nephew to Josuke!).
- Giorno gets the most distant relations to any other, infact his father side of his family is downright screwed up (his dad is Dio, no less!), but regardless he bears the birthmark since Dio had stolen Johnathan's body.
- Lupin III mixes this trope with Cross Over, featuring the titular character; the grandson of Arsčne Lupin, Goemon XIII, and Inspector Zenigata of Zenigata Heiji Covers all of Edo.
- And Ganimard III. And Lawrence III of Arabia. And Sherlock Holmes III. And...
- Lesser known is Lupin VIII, a 1982 series centering on Lupin III's descendant five generations down the line. Only a pilot was made, due to the estate of Maurice LeBlanc (creator of the original Arsčne Lupin) wanting more money than the producers were willing to pay.
- Most obscure is Lupin III Jr., a short-lived manga about Lupin's illegitimate son.
- While Chibiusa is always a main character on Sailor Moon, a later one-shot manga story, deliberately set in an alternate universe and timeline, starred the children of the Guardian Senshi, plus a brand new younger sibling to Chibiusa by the name of Kousagi. Almost all of the kids had the same names and appearances as their parents except for Kousagi, who actually looked like her own character, but Chibiusa is the sibling with her mother's name.
- The manga had numerous one-shot Chibiusa stories that ran in a separate magazine.
- The anime Final Fantasy: Legend of the Crystals was based on the world of Final Fantasy V and starred one of Bartz' descendants. Presumably the "Queen Lenna of Tycoon" is also a descendant of the original Lenna, though she's just a supporting character.
- Magical Girl Lyrical Nanoha Vi Vid. A Spin-Off of Lyrical Nanoha (yes, a Spin-Off of a Spin-Off) starring Nanoha's adopted daughter, Vivio.
- Dragon Ball Z was supposed to be this, but popular demand just didn't allow Toriyama to keep Goku out of it.
- Inverted in that Bardock, the father of Goku both got an anime special and a little manga spinoff.
- Kinnikuman Nisei is about Kinniku Mantaro, the son of the original Kinnikuman.
- Mobile Suit Gundam Wing sequel novel Frozen Teardrop takes the cast from the anime and puts them in the mentor roles while Generation Xerox versions of Duo (his son), Trowa (his student) and Quatre (his younger sister) do all the heavy lifting. As does Heero Yuy, who was in cryogenic stasis the whole time.
- The main character of The Kindaichi Case Files, Hajime Kindaichi is the grandson of famous detective character Kosuke Kindaichi, created by Seishi Yokomizo.
- Shaman King Flowers follows Yoh's son, Hana, as well as the next generation Shamans.
- Ao Fukai in Eureka Seven AO is the son of the main heroes of the first series, Renton and Eureka.
- For the most part averted in Saint Seiya Omega. Out of the six (later seven) main characters, only one is actually biologically related to a main character from the classic series (Ryuhou, Shiryu's son).
- UQ Holder is set in the 2080's some 80 years after Negima and the main character, Touta Konoe, is the grandson of Negi Springfield.
- Naruto Gaiden to Naruto.
- Slight variation in the Galaxy Angel Series Franchise: because the original Angels were the stars of a dating sim and Bishoujo Series, it would be a little offputting if they were all shown married with kids. Instead, in Galaxy Angel II and Galaxy Angel Rune, they have spinoff counterparts with other connections, ranging from Milfeulle's kid sister to Forte's combat protege. Vanilla actually does have a kid, but she's adopted.
- Ami Kuzuki from Hana No Miyako has the... interesting honor of being in a Tsukihime spinoff while also being the (biologically impossible) daughter of two Fate/stay night characters.
- Spider-Girl and the majority of the teen hero characters from Marvel Comics' MC-2 lineup.
- In another example from Marvel Comics, three of the Young Avengers (Stature, Wiccan, and Speed) are children of former Avengers members. A fourth (Patriot) is the grandson of the first Captain America.
- Older Than They Think: The Green Hornet was, believe it or not, originally introduced as The Lone Ranger's great-nephew.
- Not all that unbelievable; the Hornet and the Ranger were both created by George W. Trendle and Fran Striker as broadcast content for Trendle's Detroit radio station, WXYZ. The relationship isn't that well known, though, since it wasn't referred to that often in the Hornet's series, and in the 1950s Trendle sold the rights to The Lone Ranger to another company, which prevented the relationship from being explicitly mentioned in any subsequent The Green Hornet shows or other adaptations.
- Similar example, although it's more of an All There in the Manual than something explicitly stated: Billy Blaze is the grandson of B.J. Blazkowicz, with a more Anglicized last name.
- The original Infinity, Inc. was a DC Comics series about the children (and wards, etc.) of the Justice Society of America. Effectively the Teen Titans of their universe, though they lost this status when all of DC's Earths were merged into one. They faded into obscurity soon after. Though the JSA itself was eventually reintroduced.
- Marvel Comics wanted to do a spinoff of The Avengers for a DVD. Instead of using the popular Young Avengers franchise because characters were linked to controversial topics like drug-abuse, rape, and homosexuality, they made Next Avengers: Heroes of Tomorrow, which is essentially "Avengers Babies" with 12-year old children of the Avengers having adventures. No, really.
- The short lived incarnation of the Seven Soldiers of Victory in Grant Morrison's Seven Soldiers #0 included the Whip III, granddaughter of the Whip II (a New Old West Zorro wannabe) and great-great-granddaughter of the Whip I (an Old West Zorro wannabe); I, Spyder, son of the original 7SoV member (and traitor) Alias the Spider; and Gimmix, daughter of Merry the Gimmick Girl and, therefore, neice of the first Star-Spangled Kid, who was also an original 7SoV member. In Seven Soldiers #1, the Bulleteer turns out to be directly descended from Aurakles, the world's first superhero.
- Mention must be made of Plastic Man's son, who appeared in the Kingdom Come semi-sequel The Kingdom (DC Comics) and a one-shot special, who is actually called "Offspring". Other Spin-Offspring characters in 'Kingdom Come'' who got their own one-shots are Nightfire (Starfire and Nightwing), Kid Flash (the Wally West Flash) and Ibn al Xu'ffasch (Batman and Talia; i.e. this world's counterpart to Damian Wayne).
- The sequel to The Intercontinental Union of Disgusting Characters is called The Sick Kids. Guess who gets the spotlight!
- Whispers in the Dark, a popular Percy Jackson and the Olympians fanfiction, is about the daughter of Thalia and Luke.
- Undocumented Features: The high school students introduced in the Symphony of the Sword series include the children of some members of the Wedge Defense Force, many of whom are around the same age due to Ragnarok triggering a baby boom.
- The fanfic Courage the Cowardly Dog Jr. is this, taking place 8 years after the original series ended and taking place in a big city called Somewhere rather than a small town called Nowhere. Courage Jr. takes after his father and protects the city from supernatural fiends even worse than the ones from Nowhere while dealing with his father's original enemies and befriending the daughter of one of his dad's worst enemies.
- Aki-chan's Life follows the daughter of Shinji and Asuka that also acts as the sequel to The Second Try.
- The Discworld fanfic The Brain Thief is about Corporal Sam Ramkin (Young Sam) and Meg Garlick (Princess Esmeralda Margaret Note Spelling of Lancre) some 15 years after the events of the books.
- Fallout: Equestria - Empty Quiver picks up about twenty years following the events of Fallout: Equestria - Occupational Hazards, with the daughter and son of the leading couples. Don't think too hard about how two pairs of stallions had foals.
- The fanfic Time Fixers Nicktoons Of The Future takes place twenty years after Nicktoons Unite and centers around the children of Jimmy Neutron, SpongeBob SquarePants, Danny Phantom, Tak, and Timmy Turner teaming up as they protect their worlds from the threats of evil just as their parents did.
Films — Animation
- Several Disney sequels:
- The Little Mermaid II: Return to the Sea follows the adventure of Ariel and Eric's daughter, Melody.
- The Lion King II: Simba's Pride follows Simba and Nala's daughter, Kiara.
- Lady and the Tramp 2 follows Tramp and Lady's son, Scamp, but mostly ignores his sisters. This is what the comics made before the movie did, too.
- Return to Neverland follows Wendy's daughter, Jane (she also has a younger brother).
- The 1980 animated movie A Snow White Christmas stars the daughter of King Charming and Queen Snow, also named Snow White, who's on the run from the wicked queen (who has returned and turned her parents to ice) and is rescued by seven giants.
Films — Live-Action
- Shaft (2000) stars Samuel L. Jackson as the nephew of the original Shaft, played by Richard Roundtree who makes a cameo appearance.
- The Air Bud movies transitioned into this with Air Buddies which focuses on the sports-playing Golden Retriever's puppies. Later movies however moved away from sports and more into common adventure.
- Ace Ventura Jr., concerning the adventures of a fat kid with the classic Ace's hairstyle. A horrible idea, further plagued by the fact it is a sequel to a Jim Carrey movie(s) that doesn't have Jim Carrey in it and is a sequel to a franchise that was fifteen years old at its release.
- The Fly II focuses on Brundle's son.
- The Eddie Murphy films Dr. Dolittle and Dr. Dolittle 2 were followed by three direct-to-video sequels starring the daughter of the title character.
- TRON: Legacy: Sam Flynn proves to take after his dad.
- Indiana Jones and the Kingdom of the Crystal Skull subverts this at the end: the theme music begins to swell as Mutt picks up Indy's hat, but Indy grabs it back from him.
- Ultraman Zero, the main character of a series of films, is the son of Ultra Seven.
- There is an upcoming Disney Channel Original Movie called Descendants, which has many of the main characters being the children of heroes and villains from the Disney Animated Canon, including Prince Ben (son of Belle and Adam) and Carlos De Vil (son of Cruella De Vil).
- The 1987 Dragnet film features Dan Aykroyd as the nephew of Jack Webb's Joe Friday from the radio and TV series (with the same name). Interestingly, Harry Morgan reprises his original role as Bill Gannon in the film, now as a captain.
- Famous 5: On the Case (The Famous Five's kids)
- A go-to trope for many of Anne McCaffrey's 21st century books. (Particularly the Petaybee and Talents series.)
- Once the staple of the Xanth series: The original central character, Bink, was supplanted by his son, Dor, who was supplanted by his kids, daughter Ivy and son Dolph.
- Unfortunately, due to the abundance of anti-aging magic in the Xanthverse, all these characters are still alive — as well as their kids, grandkids, and great, great grandkids. Meaning, well, you know...
- Sons of the Oak, a continuation of David Farland's The Runelords
TrilogySaga that focuses upon the son of the Earth King battling an even bigger Bad.
- The second and third books in the Old Kingdom series mostly concern the children of Sabriel and Touchstone, the protagonists of the first book.
- Susan Sto Helit, star of several Discworld novels, is the daughter of Mort, star of the book of the same name. Quite how old that makes Rincewind and Granny Weatherwax is unclear. Blame the History Monks.
- Cohen the Barbarian's daughter (well, one of them) is a minor character in a couple of books. When Cohen is introduced, he's already very old so it's not terribly surprising that he's got a few full-grown children running around (what with all the ravishing).
- Savage Sam: Son of Old Yeller follows the journey of Travis and Savage Sam, the son of Old Yeller to rescue Little Arliss and Elizabeth Circe from Indians.
- This is the premise of the Redwall series. There's a strong continuity spanning centuries of family lines that seem to have a propensity toward getting wrapped up in epic conflicts every couple decades or so.
- A fair number of the later-set Star Wars Expanded Universe novels, although for the most part their parents are there with them. Star Wars: Legacy is almost entirely populated by new characters and the descendants of the old heroes.
- The second trilogy in Kushiels Legacy follows Phedre's adopted son, Imriel.
- Second-Stage Lensmen ends with Kim Kinnison and Clarissa MacDougal getting married. In the next novel, their children go on to become the most powerful beings in the universe.
- Kim Kinnison is himself the scion of the Kinnison line, with ancestors Ralph, Rod, and Jack (all of whom were at least semi-major characters in earlier books in the series), while Clarissa is definitely descended from Virgil Samms (the eponymous First Lensman of that book), probably through his daughter Virgilia.
- The last two books in the Anne of Green Gables series revolve around the adventures of Anne and Gilbert's children.
- In Warrior Cats: The New Prophecy, the second arc of Warrior Cats, the action focuses on Leafpool and Squirrelflight, kittens of The Hero and his Love Interest from the first arc, as well as Brambleclaw, son of the Big Bad Tigerstar. The third arc Power of Three, is about the kittens of Brambleclaw and Squirrelflight. ( Not really. They're the children of two other second arc characters, Leafpool and Crowfeather). Then the fourth arc Omen of the Stars focuses on the kittens of minor characters Birchfall and Whitewing in addition to continuing the points of view of the third arc.
- The Lord of the Rings is a particularly subtle example. Gimli and Legolas are descendants of secondary characters from The Hobbit (Gimli's father Glóin was one of the meaner dwarf protagonists, and Legolas's father was actually an antagonist). The protagonist, Frodo, is a nephew of hero of the The Hobbit. However, Bilbo raised and treated Frodo as a son.
- Nearly everybody in the Lord of the Rings is the descendant of someone important in The Silmarillion (since some characters are nigh-immortal elves or descended from them, in a few cases their ancestors are still around at the end of the Third Age when LotR is set). Elrond is descended from Eärendil, as is Aragorn (his umpty-great-grandfather was Elrond's brother). They're also both descended from Beren and Lúthien Tinúviel.
- Peter Pan is just begging for this, since every female descendant of Wendy is eventually going to get picked up by Peter and taken to Neverland to be his new "mother". While J.M. Barrie never wrote any sequels, plenty of other writers have. Notably, there's Return to Neverland (a Disney sequel about Wendy's daughter Jane), the film Hook (in which Peter grew up and married Wendy's granddaughter Moira), the book Lost Girls (which deconstructs the whole concept) and Gail Carson Levine's Fairies and the Quest for Never Land (in which modern-day Wendy descendant Gwendolyn gets her turn).
- Most of the Vorkosigan Saga is about the son of the first two books' protagonists.
- The A-to-Z Mysteries has the Calendar Mysteries, following the adventures of Bradley and Brian Pinto (Josh's younger brothers), Nate Hathaway (Bradley's friend), and Lucy Armstrong (Dink's cousin).
- This was the original plan for the Honor Harrington series, with Honor being killed and the series picking up roughly 20 years later following her son as he started his naval career, but plot developments in the Crown of Slaves branch series led to major events slated for the later books to occur sooner than intended. As a result, dealing with those major developments fell to Honor, since there was no way things could conceivably stay the same for the necessary 20 years, and she was spared.
- Son of Spellsinger is, as the name suggests, about Tom-Jon and Talea's son going on an adventure with Mudge's pups.
Live Action TV
- Page quote example: Degrassi: The Next Generation originally featured Emma Nelson, daughter of Spike Nelson from Degrassi Junior High.
- The Adventures Of Shirley Holmes (Sherlock Holmes' great-grandniece).
- The 2008 Knight Rider TV movie and subsequent show was about the son of David Hasselhoff's character.
- In a way, the Sci-Fi limited series Tin Man does this: It's revealed that DG and Azkadelia are descended from the Gray Gale - Dorothy Gale.
- The entire premise of each new season of Blackadder, with some extra generations thrown in.
- While there's a notable lack of family ties between them, three generations of Star Trek share this trope's characteristics.
- The short-lived revival of Minder starred Archie Daley, the nephew of the star character Arthur Daley from the original series back in the 70s/80s.
- In The New Tomorrow, a spinoff-slash-sequel show to The Tribe, the children worship their god Bray, who was a character in The Tribe. They also fear Zoot (who is Bray's brother, and acknowledged in the new series as the devil), showing that quite some time must have passed for a religion to have begun to form around them.
- Kamen Rider Den-O begat a couple of movies that starred Ryotaro's Grand-Kid from the Future, The Taros', plus several characters that weren't even in Den-O originally.
- Girl Meets World is a spin-off from Boy Meets World with Cory and Topanga's daughter Riley as the main character, as well as Riley's little brother, Auggie.
- The TV series Young Maverick dealt with the adventures of Ben Maverick, the son of Beau Maverick (and cousin of Bret and Bart Maverick) from the original Maverick series.
- Kung Fu: The Legend Continues featured Kwai Chang Caine, the Identical Grandson of the protagonist of the original Kung Fu... so identical that he was also played by David Carradine. The series also features the younger Caine's estranged son Peter.
- The new Dallas TV series on TNT, a reboot of the original, focuses on the rivalry between John Ross Ewing III, the son of J.R. and Sue Ellen Ewing, and Christopher Ewing, the adopted son of Bobby and Pam Ewing.
- Son of Svengoolie
- Power Rangers Samurai has Spike Skullovitch, son of Eugene "Skull" Skullovitch of Mighty Morphin' Power Rangers.
- The 1988 Mission: Impossible combined this with an Actor Allusion by having Grant Collier (Phil Morris) be the son of Barnard Collier (Grant Morris).
- In the 1990s The BBC did a comedy follow up to their popular 1940s drama serial Dick Barton: Special Agent entitled Richard Barton: General Practitioner. The focus was on Dr Barton trying to curtail his increasingly senile father's attempts to thwart entirely imaginary enemies of democracy in a small village, with flashbacks to the elder Barton's glory days. Interestingly, written by the son of Dick Barton's creator, Edward J. Mason.
- Tales of Destiny 2 is about Kyle, the son of the two main characters from the first game, but aside from him, that's it.
- Fire Emblem played around with this on occasion. The fourth game, Genealogy of the Holy War, had the main characters at the start of the game die off halfway through and be replaced with their children. Many (though not all) of the characters in The Sealed Sword were the children of characters in The Blazing Blade, which would be a straight example if not for the fact that Sealed Sword was made first. (A couple of characters from Sealed Sword were the parents of characters in Blazing Blade, and grandparents of other characters in Sealed Sword. Still doesn't work because the game that came out first takes place later.)
- Final Fantasy IV The After Years, starring the son of Cecil and Rosa, the main characters of Final Fantasy IV. There's also the daughter of Yang and Sheila joining in.
- The Mr. Driller series stars Susumu Hori, who is the son of Dig Dugs Taizo Hori and of Kissy from the little-known Baraduke. Both father and son have made appearances in each other's games since the first Mr. Driller game.
- The player character of Fallout 2 is a direct descendant of the player character in the original game.
- At least some of the player characters in Golden Sun: Dark Dawn are apparently the descendants of the player characters from the original GBA games (example: Matthew, The Hero, is Isaac's son, and looks and plays a lot like him). Due to the series' extensively developed Shipping community, along with the equally awe-inspiring Ship-to-Ship Combat, this may have some interesting results in the fandom.
- In fact, almost all of the characters are descended from the heroes or minor characters. Matthew's mother is revealed to be Jenna, Tyrell's father is Garet, but he is apparently unrelated to Rief, Mia's son. Rief's sister apparently develops a crush on Piers, ruling him out as a possible father. Karis is Ivan's daughter, but no indication is given as to who her mother might be. The remaining characters are Eoleo, who is the son of Briggs and was actually seen in Golden Sun 2 as a baby, and Himi, daughter of minor characters Susa and Kushinada from the same game. The only character whose parentage is ambiguous is Amiti, although There's strong indications that Alex is his father in the ending. Interestingly, while Isaac and Garet show up, and Mia, Ivan, and Piers are frequently mentioned, there's barely any talk of Jenna, and Felix and Sheba are conspicuously absent.
- The fairly mental Amiga/Atari ST game Wizkid was a sequel to Wizball, and Wizkid was, unsurprisingly, Wizball's son.
- Providing the page image, Ōkamiden features Kuninushi, the son of Ōkami's Susano and Kushi, teaming up with Chibiterasu, son of Ōkami's protagonist Amaterasu (as well as one of the cutest things ever). Also worthy of mention are the brush gods' children.
- Leisure Suit Larry: Magna Cum Laude and Box Office Bust features Larry Laffer's nephew, Larry Lovage as the main character in both games.
- Harvest Moon DS and it's Distaff Counterpart take place 100 years after A Wonderful Life and Friends Of Mineral Town. Everyone is an Identical Grandchild and the valley folk fall in love with the same people. The only differences are their depth, some look changes, and their names in Japan.
- King's Quest: While Graham hasn't exactly retired from adventuring, the third, fourth, sixth, and seventh games followed his kids.
- Isa, the male protagonist of Sin and Punishment: Star Successor, is the son of the two protagonists of the first Sin and Punishment.
- Soul Calibur V has Sophitia's kids becoming the new main characters.
- Red Faction did this with its spinoff movie, Origins, and last game, Armageddon - the protagonists of each, Jake and Darius Mason respectively, are the son and grandson of Alec Mason, protagonist of Guerrilla.
- Lands of Lore 2 follows of the son of the villain of the first game.
- Star Ocean: The Second Story features Claude Kenny, son of two major characters from the original.
- Phantasy Star II has Rolf discovering that he's descended from Alis Landale, the heroine of the first game. Since Chaz of the series' next chronological installment was orphaned as a child, we have no idea whether or not he's related to them, but he looks almost exactly like Rolf except for his blond hair.
- The Fate games give you the option to play this trope straight, letting you retire a character who's completed the game's challenges and pass one possession of your choice down to a new-made "descendent".
- Herbert's Dummy Run was a Mission Pack Sequel to Pyjamarama starring the son of that game's protagonist.
- Rogue Legacy has an interesting twist - the player character in each play-through is the descendent of the previous run's character. Given the nature of the game, the family line becomes quite long.
- Chuck Rock II: Son of Chuck stars the infant son of the original game's protagonist.
- Donkey Kong Jr. is a rare case where the villain's son is the Spin-Offspring.
- Silent Hill 3 focuses on Heather Mason, the daughter of original game protagonist Harry Mason.
- Often done in The Sims, since most new generations of the game involve a nominal 25-year time shift in one direction or the other to open it up to new characters and scenarios. The most obvious example is The Sims 2, which includes the four pre-made playable children from the original games as adult protagonists, and adds a few more like Brandi Broke (daughter of Bob and Betty Newbie) and Tara Kat (implied to be the adopted daughter of Ginia Kat).
- The main characters of Umlaut House 2 are mostly the kids and students of the characters from the first comic. Two of whom, Volair and Saundra's son Pierce and Jake and Rick's daughter Rhonda, were actually introduced a year before "1" ended.
- Original Life follows the children of Fisk Black, main character of Better Days.
- Violet, of Coming Up Violet was in Fur Will Fly but she was about six (instead of in high school) and her mother and stepfather were more significant characters in the latter series/
- Act 6 of Homestuck has an inversion, introducing teenaged Alternate Universe versions of the main characters' biological parents. They also consider the alternate versions of the main characters as their parents/grandparents/older brother, since due to time shenanigans they were older in this universe.
- The title characters of Nicole And Derek are the children of the main couples from You Say It First and Namir Deiter, respectively.
- James Bond Jr. (claimed by the theme song to be James Bond's nephew, because although Bond did enough sleeping around that he probably could staff a spy agency with his juniors, you can't say that in the title sequence of a Saturday Morning Cartoon!)
- In a roundabout way, Batman Beyond; though Terry McGinnis is Bruce Wayne's protege rather than his son it eventually comes out in the Fully Absorbed Finale that thanks to Cadmus, Terry biologically is Bruce's son.
- The Pebbles and Bamm-Bamm Show
- The Oz Kids, which starred Dorothy's children Dot and Neddy, the Tin Boy, Scarecrow Jr., Jack Pumpkinhead Jr., the Cowardly Lion's cubs Boris and Bela, the Wizard's son Frank, and Glinda's daughter Andrea.
- The Legend of Korra, Sequel Series to Avatar: The Last Airbender, features a few descendents of the characters from the original show:
- Tenzin, the son of Aang and Katara, as the Airbending mentor to his father's latest incarnation. He has three, later four, children of his own, also Airbenders.
- Toph's daughter Lin Beifong as the local chief of police.
- The season 1 finale gives us Zuko's grandson General Iroh.
- Season 2 introduces Tenzin's older siblings Bumi and Kya, the former a non-bender and the latter a waterbender. It explores some of the interaction between them and the not-exactly-stellar job Aang did in raising them as a group.
- Season 3 gives us Toph's other daughter (and Lin's half-sister) Suyin, founder and leader of Zaofu and mother of five. It also explores Lin and Suyin's strained relationship, and the also not-exactly-stellar job Toph did in raising them.
- Season 4 gives us Izumi, Zuko's daughter and the current Fire Lord.
- It's never made clear the relationship between Inspector Gadget and Gadget Boy, particularly if it's the same character at different ages or two distinct ones such as father and son. Heather is not unlike an older Penny, but the two girls are clearly different.
- Robotech does this in the Masters Saga to tie it into the Macross Saga. The protagonist, Dana Sterling, is Max and Miria's daughter, and Bowie is (according to the non-canon novels, at least) the nephew of Claudia Grant, one of the Bridge Bunnies from Macross.
- 101 Dalmatians: The Series focuses on Pongo and Perdita's puppies...well, most of them. Lucky, Cadpig and Rolly are the leads, while Dipstick, Whizzer, Two-Tone, Patch, and Tripod (who's new to the series) are side characters. Jewel is The Ghost.
- Filmation's Ghostbusters: Two of the protagonists (Jake Kong Junior and Eddie Spencer Junior) are sons of protagonists (Jake Kong Senior and Eddie Spencer Senior) of the series it spun from.
- Popeye And Son: Popeye and Olive Oyl finally marry and have a son named Popeye Jr. (usually called Junior). Bluto marries a woman named Lizzie, has a son named Tank, and just like his father is with Popeye, he is a rival with Junior.
- Word of God is that Pac-Man's parents in Pac-Man and the Ghostly Adventures are the original Mrs. and Mr. Pac-Man, thus technically making the protagonist Pac Jr.
- Monster High is a series about the children of famous monsters such as Dracula and the Mummy who go to the same high school. Similarly, the spinoff Ever After High is about the children of famous fairy tale characters.
- Too many examples to mention (not that saying that will stop anyone from doing so). A reading of history books will show that influential people (kings, politicians, military officers, business tycoons, celebrities, etc.) tend to have influential children who often go into the same line of work and are able to work off of their family's connections. Expect to see the same families turning up generation after generation if you take a history class.
