Changing of the Guard

Story's over. The Hero and the Love Interest have married, settled down, have no further interest in adventures - and, besides, who would look after the kids while they saved the world? Or perhaps - gasp - he died and stayed dead.

And they want a sequel.

What's a writer to do?

Why, promote the Sidekick of course. Or an ally. Or a brother or child. They haven't married and settled down yet. The Hero and his Love Interest can serve as supporting characters (and prove that they are Happily Married as a sidenote). Or the Heroic Bystander, or the Heroic Wannabe - any character that wasn't the lead can fit, if only they are promoted to lead. A Sequel Hook about their story helps, but is not required. Even new characters who have plausible relationships to the old story, such as the children The Hero and Love Interest could have - or the child the Love Interest is about to have, even if she wants to make sure he doesn't Turn Out Like His Father.

Any story is possible; the Changing of the Guard may be invisible to the characters, behind the fourth wall. However, Changing of the Guard often has the new main character move in the old character's role, and this can be noticed - from as subtle as a character twitting someone in love, because earlier in the series, when heart-whole and fancy-free, he had mocked lovers, to as formal and overt as a character handing on the responsibility - which may be a Happy Ending if he is glad to leave, a Bittersweet Ending if the character has at least some longing to go on, or a Downer Ending if The Hero died, and another character must Take Up My Sword.

Compare with Legacy Characters. When done for the right reasons, an excellent way to avoid Plot Leveling. Then, it may be dictated by real life, if an actor refuses to return, or even to increase merchandizing opportunities. These are generally less fortunate. Can lead to Generation Xerox, which is usually not done for the right reasons. Contrast Old Hero, New Pals. If done repeatedly within one storyline, it's The Rashomon.

Anime and Manga

 * Digimon Adventure 02 picked up where the first left off by having the two youngest kids team up with a whole new group, while the older heroes served as mentors.
 * Mobile Suit Gundam SEED primarily focuses on Kira. In the sequel, Gundam Seed Destiny, Kira and his love Lacus are happily living together with a score of orphans, and the focus shifts instead to Kira's friend Athrun and a younger Gundam pilot, Shinn. About halfway through the series, Kira and Lacus came back as the primary protagonists alongside Athrun.
 * Jo Jos Bizarre Adventure passes the torch to a different Joestar every new series, although they usually wind up in conflict with Dio (even indirectly) at some point. It's also common for supporting characters in one series to show up in another, like Polnareff's involvement in Part 5.
 * Magical Girl Lyrical Nanoha ViVid has Nanoha actually listening to her doctors' advice for once and temporarily resting her wings, letting her daughter Vivio, whose training she's personally overseeing and who she had proclaimed to be skilled enough to have her own Intelligent Device, take over as main character. The Guard changes back in Force, however.
 * Mai-Otome changes the main character from Mai to Arika in both versions, but the nature of Mai's eventual reappearance is very different between the two adaptations.
 * Tishe Record of Lodoss War OVA switches halfway through from Parn to Spark as the main character. Of course,
 * Similarly, the second season of Superbook had Gizmo team up with a young friend of the main characters of the first season, Joy and Chris. They kept in contact with them through a communication screen in Gizmo's stomach (he's a robot).
 * The first few episodes of Transformers Headmasters moved the main characters out of the spotlight to focus on the Headmasters. Something similar happened between Masterforce and Victory.
 * Akira Toriyama wanted to do this in Dragon Ball, switching the focus from Goku to his son Gohan, but the audience and the publisher kept demanding more Goku.
 * It has been said that he originally did want to change from Goku to Gohan, but switched the main focus back to Goku because he decided that Gohan wasn't fit for the role.
 * With every new arc and region of Pokémon Special comes new protagonists, with the old ones occasionally providing backup. The best thing about this is that since the focus isn't on one character all the time, nobody suffers from Badass Decay.

Comic Books

 * In a controversial decision, the folds in charge Ultimate Spider Man allowed Peter to be killed off. A successor named Miles Morales took up the mantle, despite being younger, smaller, and afraid of his powers.
 * Astro City had a two-issue story arc on this trope. Spider Man Expy Jack-In-The-Box is confronted by nightmarish futuristic versions of his son, who blame Jack for their fate (in their Alternate History, Jack died before they were born, and was therefore unable to be a father figure in his life). When Jack later discovers his wife is pregnant with the as-yet-unborn son, he has to decide between giving up his super-hero identity or risk leaving behind a twisted offspring. The problem is resolved when

Film

 * Short Circuit 2, sure it's still Johnny Five but now Guttenberg has been replaced with his quirky not-really-Indian sidekick.
 * The Tremors series passes the "hero torch" from Val (gets married) to Earl (opens a theme park) to Burt (when last heard from, still at it..)
 * Smokey and The Bandit Part 3 with Snowman dressed as The Bandit.
 * The often rumoured but not yet in production Ghostbusters 3 is supposed to be about the old team training a new set of recruits.
 * Indiana Jones and The Kingdom of The Crystal Skull introduces Indy's son Mutt, who may get a film of his own if Spielberg wants to make another film. Even so, the film ends with a pointed subversion of passing the torch as Indy's trademark hat is blown off its rack and Mutt picks it up. He's about to try it on when Indy snatches it back.
 * Like the Indiana Jones above, Rocky Balboa had a perfectly good opportunity to pass off his Best Boxer EVAR mantle to a young man named Steps (who did not have any other purpose to the story). He doesn't, though.
 * A meta-version of this occurs in the beginning of The Rundown when The Rock enters a club and passes Arnold Schwarzenegger, who wishes him a good time as he's leaving the club.
 * An odd example occurs with the Van Wilder series. The first movie focuses around it's titular character. The second movie then shifts focus to the sidekick,Taj. The Third movie then returns to Van, the main character from the first movie.
 * Bruce Almighty starred Jim Carrey as Bruce... and as a supporting character, Steve Carell as newscaster Evan. Steve's character would then get promoted to the lead role in the sequel, Evan Almighty.

Literature

 * Raymond E. Feist's Riftwar Series. While most of the powerful magicians are long-lived, supporting characters in the later books are typically descendants of the original protagonists. Famous examples are the descendants of Duke Borric and Jimmy the Hand.
 * JRR Tolkien wrestled with the idea of having Bilbo have more adventures after The Hobbit, but quickly decided on having a son or other relative have them instead, although it took him a while to write about Frodo.
 * Edgar Rice Burroughs played with this in his Mars books. After the third book, he began writing about a larger stable of viewpoint characters, as John Carter's own romance arc had been completed and he needed new princesses to rescue and heroes to rescue them. John Carter remained a central figure and The Hero throughout the series, however
 * Andre Norton's Witch World started with two books about Simon Tregarth. Then she wrote them about his children, or about other characters in the same world.
 * Lois McMaster Bujold went from Shards of Honor to a book about the child of its main characters.
 * Half of the "Mirror Dance" has Mark as the main character and the audience point of view. So, McMaster actually changed of the guard twice during the book.
 * Ethan of Athos qualify also for this trope, as the book is focus on Elli Quinn and Ethan.
 * Lois McMaster Bujold has done this again with the first two Chalion books. Amusingly, the heroine of the second one is the mother of a supporting character in the first.
 * Done constantly in Xanth. What generation of Bink's family are we on now?
 * Averted in the same author's Incarnations of Immortality, because most of the important protagonists are immortal, so characters from the 1200s mingle with space-age teenagers without missing a beat.
 * In the Apprentice Adept series, this is played with. The main characters in Book 4 and 5 are from the second generation, but in Book 6, the first-, second- and third-generation heroes all get equal screen time and are equally relevant to the plot.
 * Older Than Steam: Done repeatedly in the sequels to the Chivalric Romance of Amadis of Gaul.
 * Heralds of Valdemar does this, but just as often in reverse, recounting the experience of past generations rather than future ones. And then the children of past generations take the torch, but still in the past. And then their great-great-great-grandchildren show up in the present novels.
 * Terry Brooks' Shannara series does it regularly. The grandchildren of the characters of previous book typically become the protagonists of the next. Suffers from Generation Xerox somewhat.
 * Redwall: There's a new set of characters is almost every book. The only constant is the the abbey itself.
 * And there are a few novels that predate the construction of the Abbey, so not even that is entirely constant.
 * Dragonlance Chronicles has Tanis as its lead character but its sequel Legends set shortly after has the twins Caramon and Raistlin take the spotlight. The next book set years later has the children of the heroes from Chronicles as the main cast.
 * The last few Anne of Green Gables books are mostly about her kids.
 * The Sacketts series by Louis L'amour has this built-in and happening over and over. As the title suggest, the series is meant to be about the Sackett family, not one particular hero.
 * Every new one of The Chronicles of Narnia has a new changing of the guard: First, there were the 4 Pevensie siblings. Then there were two and a cousin. Then the cousin and a friend... The Prequel even established a minor character from the first published book as the major character in a previous adventure.
 * In Jacqueline Carey's Kushiel books, the first trilogy is narrated by Phedre. The second is by her adopted son, as Phedre is semi-retired from adventuring by the time he's an adult.
 * The Edge Chronicles features a new set of characters across almost everybook
 * The sequel series to Percy Jackson and The Olympians focuses on a new group of kids.
 * Rick Riordan's The Lost Hero centers about three entirely new demi-gods, not Percy Jackson and his friends.
 * The first four books of the X Wing Series had Wedge Antilles and Rogue Squadron, but the primary focus was unmistakeably Corran Horn. Those four books ended with the Rogues, including Wedge and Corran, deciding to help a planet's defenses build up after "killing" the Big Bad. The next three books were to be written by another author, who wanted to write from the POV of some of Wedge's friends creating a new squadron. Executive Meddling nixed this, so Aaron Allston had Wedge leave the Rogues for a while and create a new squadron himself. Some other characters are in common, but in different or reduced roles.
 * The first series of the Warrior Cats books started off with Firestar as the main character. He was then replaced by Brambleclaw in the Warrior Cats the New Prophecy. In Power of Three, he turns into a background character like Firestar, and is replaced by Jayfeather, Lionblaze, and Hollyleaf. Omen of the Stars has Ivypool and Dovewing as its main focus, with the Power of Three characters still in tow.
 * Most of the main good guys from the first three Emberverse books have a lot of authority in the new nation-states by the time the second series rolls around. This would put a crimp in their ability to go haring off to find the Sword of Plot Advancement when such a trip would take several years - a fact the resident Tolkien geek deeply laments - and so the task falls to the previously established Chosen One, his childhood friend, and seven more characters who either could be missed by blinking in the first three books or are completely new. While they're away, we do get the occasional glimpse of the old guard struggling to stave off the new Big Bad.
 * Discworld
 * Mort and Ysabell's story ended with them Happily Married. So for the next novel that needed a young clueless human to take on Death's role and mess things up, their daughter Susan was introduced.
 * Lords and Ladies also ends with Magrat, the Maiden of the Lancre coven, getting married. Luckily, the same novel introduces a coven of young girls messing about, one of whom -- Agnes Nitt -- actually has some talent and becomes Third Witch (eventually) in the next coven novel. Arguably, the Tiffany Aching novels mark a Changing of the Guard for the entire witches series, with Tiff becoming the main character while Nanny and Granny fade into support roles.
 * After a while, the Thoroughbred series stopped focussing on Ashley and her friends and timeskipped a few years to focus on their kids instead.

Live Action TV

 * Inspector Morse's sidekick, now the star of Lewis.
 * Power Rangers did a lot of this in its early seasons: when old actors left or started getting too old for their roles, they transferred their powers to new ones and went off to do stuff.
 * The War of the Worlds series did this when it switched into a Darker and Edgier season, throwing out decayed villains and immediately establishing the threat of the new ones with the death of two of the ensemble. Their mourning was short-lifed due to the addition of Adrian Paul as an Anti-Hero.
 * In Mash this happens to several major cast members: Henry's tour of duty ends and gets killed on his way home, and is replaced by Potter. Trapper goes home as well, in comes BJ. Frank breaks down, and is replaced by Charles. When Radar leaves, Klinger takes over his role as the company clerk.
 * Agent John Doggett replaced Fox Mulder as the male lead after the latter was abducted by the aliens in the eighth season of The X-Files. In the ninth season, Monica Reyes replaced Dana Scully as the female lead, completing the guard change.

Video Games

 * Star Ocean the Second Story, has two selectable protagonists, one of which is the son of one of the protagonists in Star Ocean The First Departure. (e.g. Star Ocean 1)
 * The ending of Neverwinter Nights was set up for another adventure, but they move on to entirely new groups of heroes in the expansions and the sequel.
 * Most games in the Castlevania series focus on a different Belmont, although sometimes they're not available due to plot purposes, like in Bloodlines, Symphony Of The Night, and Portrait Of Ruin.
 * Later installments of the King's Quest series focus on the adventures of Graham's (the original protagonist) descendants.
 * Eternal Darkness levels end (which often involves the death, or worse of said character) although it still has a protagonist who's played in the intervals between chapters.
 * Fire Emblem 4 skips 17 years after its halfway point, so pretty much your entire army will be replaced by the children of your units.
 * This trope works backwards in the 6th and 7th Fire Emblem games. FE 7 was a prequel to FE 6, so it naturally starred the parents of several of the 6th game's characters.
 * Chrono Trigger and Chrono Cross. The main characters from the former are all out of the picture somehow (dead, in another time, or busy elsewhere), but before they left they set up an unimaginably complex Gambit Roulette to produce the main characters of the latter and get them to be in the right places at the right times.
 * Apollo Justice takes over from Phoenix Wright in the Ace Attorney games. Well, he technically does - the fact that the entire Apollo Justice game centres on what happened to Phoenix left some fans unconvinced. Still, Phoenix's pals were absent, to allow for a new cast.
 * It actually was suppose to be a whole new set of characters but Executive Meddling caused it to include Phoenix and the writers had to make it so that Phoenix couldn't just swoop in and save the day.
 * The son of the main characters from the previous game is implied to the new hero in Final Fantasy IV the After Years and the game also focuses a good deal on the other children of the previous heroes as well, but the old heroes are quite active in the story themselves as well.
 * Dragon Age II continues the history of Thedas post-Fifth Blight (which was depicted in Origins) but with a new lead character and a mostly brand-new supporting cast.
 * Valis IV introduces a new heroine named Lena Brande, since Yuko, heroine of the previous games, Ascended to A Higher Plane of Existence at the end of Valis III. Cham and Valna return as supporting characters.
 * All the games in The Tale of Alltynex trilogy does this.
 * At the end of Final Fantasy X, Tidus . Obviously, Square Enix couldn't make him the protagonist of the sequel, so the story centers around Yuna instead and her quest to bring him back.
 * Pokémon series has had by far 6/12/13 heroes (depending on how you count) (Red/Leaf, Ethan/Kris/Lyra, Brendan/May, Lucas/Dawn, Hilbert/Hilda and the new, unnamed heroes) in the main series. In Orre games, there's Wes in Pokémon Colosseum and Michael in Pokémon XD. Ranger games have 3/6 heroes (Lunick/Solana, Kellyn/Kate and Ben/Summer). Then there's Mark/Mint from TCG games, an unnamed hero from Pokémon Conquest, Todd Snap from Pokémon Snap and Lucy Fleetfloot from Pokémon Troizei/Link. It's probably used to justify Bag of Spilling.

Web Comics

 * Scary Go Round started with the characters Tessa and Rachel (let's call them the "New Guard") as protagonists, but they were soon complemented with and eventually usurped by characters from John Allison's previous webcomic Bobbins. For a while Shelley, Amy, Tim, and Ryan (the "Old Guard") reigned supreme, but then a batch of younger characters, in particular The Boy and Strange Girl / Perky Goth Esther (the "Young Guard" along with their friends) gradually took over. In the final chapters of SGR, the younger siblings of the "Young Guard", mainly Lottie and Shauna (the "Kid's Guard") starred (and transitioned into the successor webcomic Bad Machinery).
 * The "Old Guard" remained until the end too: the very last couple of comics show Shelley saying goodbye to Amy and Ryan and leaving town. As Lottie is the sister of Esther's best friend and both of them have met Shelley, it's almost my case of Take Up My Sword in the investigating-local-weirdness game. Ryan and Amy still appear in Bad Machinery as supporting characters - Ryan is now Shauna and Lottie's teacher.

Web Original

 * Red vs. Blue: After the end of the fifth season, the show was brought back with the miniseries Recovery One, which featured a new protagonist named Agent Washington in the starring role. None of the original main characters reappeared, and the only returning characters were Delta, featured in the first miniseries Out of Mind, and Wyoming, who appears briefly and without any lines. Washington continued as the protagonist into the next season, Reconstruction, where the original cast gradually joined him.

Western Animation
"Katara: "Aang's time has passed. My brother and many of my friends are gone. It's time for you and your generation to take on the responsibility of keeping peace and balance in the world. But I think you're going to be a great Avatar.""
 * Batman Beyond is about Batman's replacement. The original Batman acts as The Obi-Wan.
 * The entire purpose of Transformers the Movie was to kill off the old toys to make room for new ones.
 * Almost happened with the GI Joe Movie as well, which was in production around the same time. The negative reactions from the audiences prompted the executives to rework the plot, allowing Duke to live. Still happened to an extent with Cobra Commander however.
 * A common Disney tactic:
 * The Lion King 2 is about Simba's daughter, Kiara, rather than about Simba.
 * The Little Mermaid II: Return to the Sea is about Ariel's daughter more than Ariel herself.
 * Lady and The Tramp II: Scamp's Adventure is, as the title indicates, about Lady and Tramp's son Scamp, not them.
 * Extreme Ghostbusters does what the above-mentioned Ghostbusters 3 planned to do: focus on Egon training a new group. The Real Ghostbusters haven't quite quit, though, and return for one two-parter.
 * This was sort of the entire point of Tiny Toon Adventures -- the old school Looney Tunes ran an academy at which they could teach their skills to the next generation of Suspiciously Similar Substitutes.
 * In the The Legend of Korra, episode "Welcome to Republic City" Katara, aged survivor of the previous series Avatar: The Last Airbender, lampshades this in her Passing the Torch speech to young Avatar Korra:


 * It was played with a little bit previously, as the Avatar is a constantly reincarnated series of heroes, and Aang was frequently compared with his previous incarnations Roku and Kyoshi. Korra gets it a little worse though as there are plenty of people living who still remember Aang.
