- As Yahiko prepares to face off against Kenshin in the final chapter of Rurouni Kenshin, he is instructed to "think back to all the battles he's fought" before striking; this of course is an excuse for a two-page spread with portraits of nearly every villain and supporting character to have appeared in the series (even ones Yahiko never met).

Chapter 190 goes a step further and shows each one of them left individualized well wishes for Medaka.

- The cover of JLA/Avengers #3 shows everyone who had ever been an Avenger or JLAer to that point, even if they're not otherwise involved in that particular Intercontinuity Crossover. Although the plot was as such that every one of them was technically involved in the conflicts of issues 3 and 4. Especially 4, which is filled with these - it's George Perez drawing a battle that involves every Avenger, every Leaguer, and possibly every supervillain ever culled from the timestream.

- The tenth-anniversary Garfield Sunday Strip (running on June 19, 1988, exactly ten years to the day) opened with Garfield's tenth birthday party being attended by just about every primary and secondary character who'd ever appeared in the strip - including Jon Arbuckle's old roommate Lyman, who had not been seen in years. "If you brought me any presents," Garfield tells the crowd, "you may stay."
- "The Stockbridge Showdown" in #500 of Doctor Who Magazine has the Doctor reunite almost all the DWM strip's original companions (the exception being Fey Truscott-Sade) to finally take down the strip's best known recurring villain, whose inital arc was aborted in 1984.
- Calvin and Hobbes: The Series: The scene where the MTM uses the Mind Probe to search Calvin's mind is filled with one-off characters from previous episodes.
Suddenly a rush hit Calvin like a thunderbolt. In an instant he relived every single moment over from the point he and Hobbes flew into the pond on that winter day to the present moment. Retro Griffin reaching for him and Hobbes in the wagon with the claw car. Rupert firing his ray gun at him, Hobbes, Stupendous Man, Tracer Bullet and Spaceman Spiff.

As with Deathly Hallows, everyone that comes back does something, except for Glew, who comes back and does nothing.

- A very early example: The end of "The Massacre of St Bartholomew's Eve". Steven, after a very severe What the Hell, Hero? moment, announces that he's leaving for good. In the TARDIS, the Doctor, now without companions, has a little Soliloquy in which he talks about his first three companions, all of whom had left.

In addition to the new characters Madame Vastra, Jenny and Strax, his army included the pirates Henry and Toby Avery, a squadron of Dalek-enhanced Spitfire planes, and the black marketeer Dorium Maldovar. For bonus points, Rory went into battle in full costume as "The Last Centurion", and was introduced as such by Amy in the opening (the latter was lampshaded, as Rory wonders aloud why the Doctor had him do so and never gets an answer).
- "Asylum of the Daleks" boasts every Dalek model ever built, and recreations of some missing ones, while the later episode "A Town Called Mercy" has the Doctor naming the last few major villains of the revived series.
- Series 7's finale, "The Name of the Doctor", has appearances by all eleven Doctors up to that point — the Eleventh obviously still played by Matt Smith, and the other ten using a mixture of body doubles and archive footage.

- "The Day of the Doctor" manages to top the Series 7 finale with all thirteen Doctors — including a first official appearance by Peter Capaldi's Twelfth Doctor — charging into the fray during the climactic battle (again, via archive footage).

- The Legend War is one of the Gokaiger concepts brought over to Power Rangers Megaforce, which starts as an adaptation of Tensou Sentai Goseiger. At first, it's seen only as Troy's dream, but it's yet to be seen (although very likely) if it wasn't exactly a dream. Also, the small Power Ranger figures lining the walls of the team's base (which are modified Ranger Keys from the teams that were adapted for Western audiences) counts as this too, at least while the show is going about adapting Goseiger.
- In GoGo Sentai Boukenger, there's a fight in the Precious bank, where every Artifact of Doom from the whole season is kept. Satoru and Ryuuwon do battle with many a MacGuffin of the Week that hadn't been mentioned since its original appearance.

- The entire series finale of Chuck is one big parade of Continuity Nods, bringing back: Fulcrum, the Ring, the Wienerlicious, Jeffster!, Casey's Desert Eagle, and Mama B, and heavily focuses on the entire history of the Intersect mythology including references to Bryce, Stephen, Ted Roark (virtually unmentioned since Season 2) and Hartley/ Volkoff. In fact, much of the entire final season itself serves the purpose including appearances by Daniel Shaw, Director Graham and Sarah's adopted little sister who was mentioned once in the series's fourth episode, and was never brought up again prior to that point!.
- Likewise, the final episode of Farscape served up a Continuity Cavalcade during it's "previously on" segment, by showing clips of almost every one of the previous episodes in about five seconds.

- In the sci-fi shop They Walk Among Us, Rimmer finds a piece of artificial snake skin, "like the one the polymorph turned into", a reference to the Series 3 episode "Polymorph".

- Noddy, the clerk at They Walk Among Us, has a number of suggestions on how the crew can find propmaker Swallow's business establishment, Nose World:

- "Frank Falls Out the Window" features a range of references to previous episodes. Frank and Charlie make Grilled Charlies and Rum Ham before Frank falls out the window and thinks that the year is 2006.

It features references to the movie that inspired it in the form of Astro the Dog, other MCU movies (an Ultron drone can be seen in the queue), and other Disney Theme Parks, as the Abominable Snowman from the Matterhorn, Figment, and a bellhop's hat are on display.
- The various versions of The Twilight Zone Tower of Terror had numerous references to the show, which can be found on the ride's main page. This is apparently due to the fact that the imagineers who designed the ride, in preparation, watched every episode of The Twilight Zone (1959) twice, and couldn't resist sticking in references.
- The pawn shop in King's Quest VI contains loads of items that reference puzzles from the previous games—and would have easily solved them had you come here first.
- The final battle of Dragon Age: Origins includes this; several of the characters you met earlier in the game will show up to help you kick the Archdemon's ass, in addition to the many unnamed Red Shirt members of your army.
- Roger's quarters on the SCS DeepShip 86 in Space Quest VI: Roger Wilco in The Spinal Frontier features mementos from all his past adventures, including the Xenon Army Knife from SQ1, the Labion Terror Beast Mating Whistle from SQ2, and the SQ4 Hintbook.
- Persona 4 has the characters go on a trip to Tatsumi Port Island, including a jaunt to Gekkoukan High School.
- Mass Effect dove head-first in this direction, judging by all the effects of importing your Old Save Bonus from the first game into the second, which then pass into the third.
- From major decisions affecting the overall plot, to receiving emails from one-off characters who were previously Quest Givers, you have a very good reason to continue a given version of Commander Shepard in his/her quest to save the galaxy. Unfortunately, bugs or designer oversight do tend to show up in these situations. In Mass Effect 2, regardless of how you handled him in Mass Effect, Conrad Verner will claim that you shoved a gun in his face. Other than that and a few other examples the writers have been very diligent about transferring your decisions from the first game to the second and third. Some bugs in the first two games have since been addressed in Mass Effect 3. If in the original Mass Effect you did not threaten him with said gun, he will apologize about making the claim that you did.
- There's the instance just before the final battle sequence in Mass Effect 3, where you can call up all of your former party members and chat with them about their role in the upcoming fight.
- The final DLC, Citadel (set before the finale), climaxes with Shepard and every surviving party member from the series getting together and throwing a party. The rest consists almost entirely of Call-Back jokes and Lampshade Hanging.
- Pokémon Black 2 and White 2, surprisingly enough, brings back almost every Gym Leader and Champion from the series in one massive bonus Boss Rush. Including Red.
- In Max Payne 3, one of the Nostalgia Levels takes Max through a cemetery where four dead characters from previous games are buried. In addition, the title of every achievement is a quote from the first two games.
- In Castlevania: Portrait of Ruin, the "Greatest Five" Dual Crush attack summons the five Belmonts: Richter, Leon, Trevor, Juste, and Simon to attack all enemies. Occasionally, Trevor and Simon would appear in their original NES sprites.
- The museum in Ultima IX is a repository for artifacts that had fallen from the Avatar's Bag of Spilling over the Ultima series.
- MOTHER 3 features a boat ride through a museum of sorts filled with items from the previous game (EarthBound).
- In Tomb Raider III, in Lara's mansion, there's a trophy room with several artifacts from the previous Tomb Raider games.
- Ratchet & Clank: Into the Nexus: In the last world, there's a museum that features not just some of the worlds visited and weapons used, but all the villains and even some animals from all the series.
- In Grand Theft Auto V, you can visit a recreation of the Hollywood Walk of Fame, which lists almost every in-universe entertainment personality from the entire series.
- The GCPD evidence room in Batman: Arkham Knight holds most of the gadgets/weapons/other personal items of the various villains of the previous games.
- At the end of the tutorial in Hitman (2016), we're treated to a montage of various targets from Hitman: Codename 47, Hitman 2: Silent Assassin, and Hitman: Blood Money being assassinated in the most popular ways you could do so in those games while narration talks about 47's past success.
- Final Remixes in the Rhythm Heaven series are usually a Final-Exam Boss in that they're made entirely of short moments in every stage in the game (excluding other remixes). The Final Remix of Rhythm Heaven Megamix, taking it Up to 11, becomes this trope in its latter half, with the music turning into a medley of the main themes of each Rhythm Heaven game in order of their release (including Megamix), with stages from those games as the main themes play.
- The Grim Adventures of Billy & Mandy features several references and callbacks to characters and events from the series, such as Billy's dad Harold being playable as his Mogar persona from "Battle of the Bands" and the tree from "The Taking Tree" appearing as a background hazard in the level taking place at Billy's house. In addition, Boogey's Mojo Meltdown, his alternate costumes, the Boogey Bay level, and the alternate costumes Billy and Mandy get from completing two of the missions in mission mode allude to the TV Movie Billy and Mandy's Big Boogey Adventure in spite of the movie not being released until less than a year after the game.
- In Adventurers!, most of the summons seen in the comic return when Ardam summons Pantheon.
- Panel two of this Bad Machinery strip features no less than four characters from Scary Go Round, the comic which Bad Machinery is a Spin-Off of.
- In Homestuck, one of the author's goals is to build a heavily self-referential narrative. He pulls it off so well that to list the individual examples of this trope would take its own page, but the introduction of new characters in Act 6 is probably the most outstanding example of this thanks to said characters originating from the use of a Reset Button.
- Burnie Burns describes the finale of Red vs. Blue: Revelation as a scene where the protagonists "win by saying Red vs. Blue quotes to each other."
- Happens again in the penultimate episode of season 10, with the references (ranging from the first to the current season) taken up a notch or two. It's quite effective.
- Near the end of the "Bob Ross vs. Pablo Picasso" episode of Epic Rap Battles of History, Pablo Picasso flips through the channels on his TV to bring up PBS, where Bob Ross is rapping from the TV screen. Along the way, we see him flip past Billy Mays (from "Billy Mays vs. Benjamin Franklin"), Mr. Rogers (from "Mr. T vs. Mr. Rogers"), and the Fourth Doctor (from "Doc Brown vs. Doctor Who").
- In the "Lewis and Clark vs. Bill & Ted" episode, most of the historical figures that Bill and Ted encountered on their adventure (Abraham Lincoln, Ludwig Van Beethoven, Napoleon Bonaparte, Genghis Kahn and Joan of Arc) had already been in at least one previous rap battle, so for the end of Bill and Ted's first verse, all five of them appear to support B&T.
- In the "Darkwing Duck for the TurboGrafx16" review of The Angry Video Game Nerd, the Nerd reveals his "Shit Scale", which messures how horrible a game is. All the examples represent his previous reviews. On the lowest end are debatably bad games (Metal Gear for Nintendo Entertainment System, Teenage Mutant Ninja Turtles for NES, and Castlevania II: Simon's Quest), followed by games that are horrible yet still playable (Dick Tracy for NES, Super Pitfall, and Top Gun for NES), then the more traumatizingly horrible ones (most of the LJN Toys lineup, the Virtual Boy, and Link: The Faces of Evil, then games that he claims could kill a person (Action 52, Dark Castle for Sega Genesis, The Wizard of Oz for Super Nintendo Entertainment System, and the many handheld LCD games from Tiger Electronics), then a section dedicated solely to Dr. Jekyll and Mr. Hyde for the NES, and finally, games that don't even qualify as games (Desert Bus from Penn and Teller's Smoke and Mirrors, CrazyBus, Hong Kong '97, and Plumbers Don't Wear Ties).
- Taco-Man Plays a Video Game:
- Taco-Man Plays Atari 2600 begins with Taco-Man drinking at a bar populated by characters from previous episodes of Taco-Man Plays a Video Game, as well as the girls from his Night Trap parody.
- Taco-Man's 2015 Halloween special has characters who appeared in some of his other cartoons and reviews stop by while he waits for part two of the game (the aforementioned Night Trap parody) to load, and after he completes the game. He naturally Lampshades this, with Flat Joy, after Blobert from A Boy and His Blob pops up to request some jellybeans:
Taco-Man: Oh, look. It's a character from a previous episode. How original.
- The brief animated segment at the beginning of episode 6 of Don't Hug Me I'm Scared is covered with items and characters from the previous episodes. The episode also features Red Guy reprising the "creative song" from episode 1. Additionally, all of the previous teachers make short cameos near the end, as Red Guy is messing with a machine that controls them.
- The Robot Devil's wheel with the name of every robot ever seen on the show in the episode "The Devil's Hands Are Idle Playthings".
- During Fry's funeral in "The Sting", every character who had ever been romantically involved with him during the show appeared in one shot.note Including an inanimate radiator.
- The scene◊ from "Into the Wild Green Yonder"—it was planned to have literally every previously shown character in it, but to keep continuity with a line in script it's instead every adult character.
- In "The Late Phillip J. Fry", when Fry, the Professor and Bender jump through to the birth of a new universe, they quickly go through several Futurama events, including the two destructions of New York seen in "Space Pilot 3000".
- The Simpsons:
- Maude Flanders' funeral in "Alone Again, Natura-Diddily" opens with a panning shot of the Springfield Cemetery with the gravestones of several characters who died in previous episodes (including Beatrice Simmons, whose name is followed with "(GRANDPA'S GIRLFRIEND)").
- In The Simpsons Movie there's a shot of the townsfolk coming after the Simpsons with torches, which includes every character that has ever appeared on the show. This also applies for all crowd shots in the movie. In the show, nameless, random people fill the crowds with random recurring characters sprinkled here and there. In the movie, as a bit of Pandering to the Base, there are no nameless, random people in the crowds. They all consist of characters who have appeared on the show at least once.
- "Homer's Enemy" - Frank Grimes marvels at Homer's wall covered with pictures of Homer being in space ("Deep Space Homer"), touring with The Smashing Pumpkins ("Homerpalooza") and having a beer with Gerald Ford (the ending of "Two Bad Neighbors"). Homer also mentions that he won a Grammy ("Homer's Barbershop Quartet").
- "You Kent Always Get What You Want" - The Wall of Casual Acquaintances Who Came To Stay For a While ("Apu sang a song, what're you gonna do?")
- "Poppa's Got a Brand New Badge" - Homer lists all the jobs he's ever had up to that point. Marge, meanwhile, has a Long Speech Tea Time.
- Any time the attic or the closet is shown, various items from past episodes are seen stored there. You might see a Pin Pals jacket from "Team Homer", or a painting of Ringo Starr from "Brush with Greatness". The Olmec head from "Blood Feud" can be consistently seen in the basement.
- "Team Homer" had a bowling team called "The Homewreckers," comprised of four people from past episodes who had caused trouble in Homer and Marge's marriage.
- Similarly, "The Ziff Who Came to Dinner" had every character voiced by Jon Lovitz sitting at Moe's for a drink, including one-episode characters such as Llewellyn Sinclair and Aristotle Amadopoulos.
- In "Eternal Moonshine of the Simpson Mind", in a sequence that pays homage to the YouTube video "Noah takes a photo of himself every day for 6 years", there are scenes that reference episodes that deal with Homer's past in some way (such as "Mother Simpson" and "The Way We Was"), and towards the end we get a montage of Homer wearing various costumes he had worn throughout the show's history.
- The Couch Gag at the beginning of the 500th episode was a rapid-fire montage of every other Couch Gag in the history of the series.
- Avatar: The Last Airbender:
- During the Invasion in "Day of Black Sun", several characters whom Team Avatar has worked with over the course of the show are there.
- The episode "The Ember Island Players" is one huge continuity nod, with a good dash of parody thrown in for good measure. As the last episode before the four-part finale, it served to recap the entire series up to that point.
- The end of "Sozin's Comet Part 4: Avatar Aang" shows shots of the crowds cheering at Zuko's coronation, where fans see a smorgasboard of minor characters from throughout the show in attendance.
- The Legend of Korra:
- "Beginnings" references almost every single thing known about the lore from the previous series surrounding the nature of the avatar, and it also references important scenes from the series finale of The Last Airbender.
- In "The Stakeout", Zaheer references Korra's separate encounters with President Raiko and the Earth Queen, the air nomad genocide done by the Fire Nation, the characters of Wan and Vaatu, the spirit portals, and Unalaq all in one sitting.
- "Venom of the Red Lotus" has crystal caves similar to the ones found in the Book 2 finale of The Last Airbender, a battle setting reminiscent of the final battle also in the original series, the villains of the previous seasons making cameos, and there is an important Call-Back to an aspect of the Avatar State.
- The end episode of Foster's Home for Imaginary Friends has several of these:
- Throughout the episode, the background is full of occasionally seen objects like the secret door the Scribbles use to be in, the door to the room the imaginary fleas stay in, and the Extremosaur pen.
- Bloo tries to find something great to do with Mac, but all the things he lists are things they'd done already.
- The episode ends with goodbye card for Mac, which is signed by every imaginary friend to have appeared on the show (and Craig McCracken). The inside of the card is only visible for a few seconds, so it's something of a Freeze-Frame Bonus.
- South Park:
- The 200th episode, "200", which not only features a plot that was just a pastiche of a few previous episodes to feature the biggest continuity gag ever, it also features 200 celebrities the people of South Park have parodied (including some who had not previously been shown like Tim Burton), with an epic redux of Mecha-Streisand.
- The following episode, "201", does it again, continuing the story while connecting it to just as many previous episodes' plots, culminating in Scott Tenorman from "Scott Tenorman Must Die" as The Man Behind the Man led by his army of ginger-haired people from "Ginger Kids".
- Codename: Kids Next Door
- Much of the scavenger hunt sequence of the finale was loaded with references to previous episodes.
- In addition, this seems to be Mr. Boss's schtick. Any time he is the episode's antagonist, expect to see an entourage of at least a dozen previously-seen villains, if not more.
- The series 1 episode "Operation QUIET" had reappearances of Toilenator, Lola, Lizzie, Wally's Numbuh 1 disguise, Professor Tripleextralarge (who had finally developed the ultimate snowcone), Stickybeard, and the Common Cold, as well as Lizzie mentioning how she wants to take Nigel to The Point.
- "Operation IT" has appearances from every single KND operative, as well as every single treehouse seen to date.
- All the guests attending the wedding in the Duckman episode "Four Weddings Inconceivable".
- Phineas and Ferb's "Rollercoaster: The Musical" episode in its entirety, especially the last song, "Carpe Diem".
- Near the end of Phineas and Ferb The Movie: Across the 2nd Dimension, almost all of the inventions made by the boys throughout the show up to that point are used to fight off Doof-2's army.
- The Penguins of Madagascar: Several episodes were concluded with the Monster of the Week being sent to Hoboken, so when the penguins end up there in "The Hoboken Surprise", they run into all their previous enemies (and Lulu, who was shipped there for different reasons).
Skipper: What in the name of returning guest characters? It's villain-mageddon!
- Courage the Cowardly Dog episode "Ball of Revenge", when Eustace brings all of the Monsters of The Week together to gain revenge on Courage.
- "Til Nephews Do Us Part," the finale to the first season of DuckTales, featured appearances from just about every character that had appeared in the show to date at Scrooge's thankfully failed wedding to Millionara Vanderbucks, from supporting characters to one-shots.
- The Family Guy episode "Yug Ylimaf", in which Brian and Stewie reverse time and several past events are recalled.
- My Little Pony Friendship Is Magic:
- The episode "Apple Family Reunion", as you might guess from the title, has an appearance from nearly every single Apple Family member from the first three seasons. There are even a few ponies at the reunion that weren't previously connected with the Apple family, such as recurring background ponies Cherry Berry, Golden Harvest, and Cloudchaser, as well as Hayseed Turnip Truck from "Sweet and Elite".
- The episode "Magical Mystery Cure" features Princess Celestia showing Twilight how far she's come with floating clips from just about every previous episode. Also, when the members of the Mane Six are changed back to their true destinies, clips of them doing their jobs fly in rapid succession through their eyes.
- In "Pinkie Pride", Pinkie looks through photos of parties she's thrown in past episodes, including her very first party shown in "The Cutie Mark Chronicles", Twilight's welcoming celebration in the first episode, her pet alligator Gummy's birthday party in "Party of One", and the royal wedding ceremony in "A Canterlot Wedding".
- "Do Princesses Dream of Magic Sheep?" is an onslaught of callbacks to gags and plot points from previous episodes during the final dream sequence, from major ones like Flutterbat and the Power Ponies to incredibly minor ones like Beefcake Spike from his imagine spot from "A Dog and Pony Show" and even the classy lamp brought to life by Discord's sneeze in "Three's A Crowd".
- "The Cutie Remark" features all the previous major villains (and the Flim Flam Brothers) as rulers of increasingly worse Bad Futures caused by Starlight Shimmer changing the past so that the Mane Six never became friends.
- The Mega Babies episode "Balemtine's Day" brings back every surviving villain seen in the show to that point.
- Gravity Falls:
- "The Time Traveler's Pig," we see numerous previous episode events both during the episode proper (when Dipper and Mabel are fighting over the time-travel device) and again during the credits (when the time traveler is assigned to clean up the messes Dipper and Mabel left!). Said montage was set up by minor details in the episodes themselves.
- The episode "Dreamscaperers" takes place in Stan's mind so moments from previous episodes are scattered throughout. Plus, the episode makes references to some Noodle Incidents as well as some of the symbols seen in the book.
- In "Into the Bunker", The Shapeshifter takes forms of previous antagonists of Season 1.
- In "Sock Opera", Bill Cipher tries to persuade Dipper into making a deal with him that will effect Mabel's efforts, stating "What has she ever done to return the favor?" whilst showing flashbacks of his sacrifices in Season 1.
- The three-part "Weirdmageddon" Grand Finale has almost every character and mythical creature/oddity encountered in the previous thirty-seven episodes appear to some degree.
- In the Littlest Pet Shop (2012) episode "Blythe's Big Idea," most of the 42 passengers in the imaginary jet are animals previously seen in the series up to that point. Not including main characters, they include: Madame Pom, the storefront tortoise, and the storefront snake from "Eve of Destruction"; the snarky bluebird from "Summertime Blues"; Olive Shellstein from "Helicopter Dad"; Esteban from "Blythe's Crush"; the pug at Minka's art show, Oscar, and Genghis from "Bad Hair Day"; Mary Frances from "Russell Up Some Fun"; Scout from "Books & Covers"; Ollie from "Eight Arms to Hold You"; Tiger from "Gailbreak!"; two of Zoe's competitors from "Terriers & Tiaras"; the mother white tiger and her three cubs from "Lights, Camera, Mongoose!"; Digby from "Trading Places"; Wiggles McSunbask from "Alligators and Handbags"; Sugar Sprinkles from "Sweet (Truck) Ride"; and two of Pete's friends (but not Pete himself, oddly) from "What Did You Say?"
- In the Archer Season 5 premiere "White Elephant", after the characters in the main cast are all arrested for treason by the FBI, all of them—with the exception of Lana and Archer—immediately start blabbing to their interrogators in hopes of escaping prison time. Cue a long montage of everyone recounting past missions from about twenty previous episodes, to a gaggle of increasingly perplexed FBI agents.
- Inverted in Batman: The Animated Series; the Batcave is full of nods to trophies that appear in its counterpart in the comics, and some episodes of this and other DCAU shows (such as the Two-Face segment on "Almost Got Him" and Superman fighting a robotic T-Rex in the pilot to Superman: The Animated Series) retroactively explain how they got there. Played straighter in Batman Beyond, where the Batcave will often display trophies from B:TAS such as Mr. Freeze' freeze gun or the uniforms of Bats' various sidekicks.
- Scooby-Doo! Mystery Incorporated does this in the Season 2 episode "Wrath of the Krampus", where the ending reveals that the entire episode's Monster of the Week plot was actually a Massive Multiplayer Scam that the gang pulled off with the help of several of their previous adversaries to steal the three pieces of the Planespheric Disc from Mr. E's vault. The Krampus turns out to be Charlie the Robot (from the original series episode "Foul Play in Funland") remotely controlled by Jason Wyatt (from "Howl of the Fright-Hound"), who pretends to pursue Mary Anne Gleardan (from "The Song of Mystery") to distract Mr. E and his allies while Marcy "Hot Dog Water" Fleach (a recurring character who was the Monster of the Week in "Menace of the Manticore" and "Night on Haunted Mountain") burgles the vault (using the knowledge of Mr. E's headquarters that she obtained while serving as his operative in "House of the Nightmare Witch"), with the now-incarcerated Mayor Jones (not seen since "All Fear the Freak") safe-guarding the gang's Planespheric Disc pieces while they switch them out with a set of fake pieces. For bonus points: Grady and Greta Gator (from "The Creeping Creatures"), Alice May (from "The Legend of Alice May" and "Pawn of Shadows"), Grandma Moonbeam (from "When the Cicada Calls"), Dan Fluunk (from "Night Terrors") and Ernesto (from "The Shrieking Madness" and "The Siren's Song") can all be seen in the prison cafeteria, and the Green Ghosts (from the original series episode "A Night of Fright is No Delight") show up as enemies in an arcade game.
- In Ed, Edd n Eddy's Big Picture Show, at the joke factory, Eddy pranks Ed by offering him a stick of electric gum. When Ed gets shocked, he flashes between several of the forms and outfits that he's had over the course of the series.
- The Rugrats spinoff All Grown Up! made several callbacks to the original series in the episode "Curse of Reptar". While reminiscing on their fondest memories with Reptar, the gang bring up that Reptar was the subject of their first movie (a callback to the original series episode "At the Movies"), they once went to an ice show about Reptar (referencing "Reptar on Ice"), and that Reptar was indirectly responsible for Chuckie getting a new mother and sister (a reference to Rugrats in Paris).
- Samurai Jack
- In the episode "The Aku Infection", the scene where Jack becomes motivated to fight Aku's influence when his parents remind him of his noble deeds features appearances by many of the allies Jack made and the people he helped out thus far, including the Scotsman, the Woolies, and the Triseraquins.
- The 2017 revival does this in the sixth episode, where Ashi searches for Jack and on her journey encounters a lot of people Jack encountered in the original show, including the Woolies, Da Samurai, the three archers that were cursed by a wishing well, and Olivia.
- The Adventures of Jimmy Neutron: Boy Genius had this happen in the episode "Who Framed Jimmy Neutron?", where Sheen asks if several villains Jimmy encountered in previous episodes are the ones who framed him for stealing a million dollars.
- Kaeloo: In Episode 105, Kaeloo, Quack Quack and Mr. Cat see multiple screens showing almost every time in the series so far where they made fun of or abused Stumpy.
- One of the last episodes of Regular Show, "Meet the Seer", has scenes from dozens of the show's previous episodes play on television monitors as the episode's titular seer describes the past adventures of the main characters to them in Leaning on the Fourth Wall terms.
- Later in the season, the characters outright record their memories of the past eight seasons in a Blu-Ray boxset (that includes two bonus discs).
- The final season of Transformers: Robots in Disguise is basically a "greatest hits" collection for both the previous seasons and the other shows in the same continuity. Not only do numerous characters make return appearances or get mentioned, but various notable locations and gadgets are revisited. This culminates in the series finale, in which all the guest Autobots return to help thwart the Greater-Scope Villain.
- In the Ready Jet Go! episode My Fair Jet, one of the tasks that Jet has to do in order to be a regular Earth kid is to sort a bunch of pictures that Sunspot took in previous episodes, such as the butt picture from "Satellite Selfie", and the Great Red Spot Club group picture from "Sunspot and the Great Red Spot".
- On historical anniversaries, civic groups sometimes organize gatherings of all surviving holders of a particular office, many of whom may have not been seen in a public forum for many many years. For example, see this 2009 photo-op◊ featuring all the surviving governors of Alaska. It became standard for the new President of the US to get a photo taken with all the living former presidents.
- Other times, people do big group photos of related individuals simply because it's cool. The most notable is probably A Great Day in Harlem, a 1958 image of 57 of the greatest Jazz musicians alive at the time.
- This picture from the 1927 Solvey conference◊ is a similarly gobsmacking collection of great physicists from Albert Einstein to Marie Curie.
- At some sports Halls of Fame, they will introduce all the living Hall of Famers who made the trip. The most notable of these is the Baseball Hall of Fame, since they usually get the most people to show up, including some in poor health and others who rarely make public appearances.
- At the Academy Awards ceremony in early 1998, the Academy celebrated the 70th anniversary of the Oscars by having all still-living Oscar-winning actors and actresses (including Best Supporting winners) stand on the stage together, with that year's winners taking their places last. Amusingly, Jack Nicholson won his third acting Oscar that year, so he essentially joined...himself.
- It is popular in the culture to portray Heaven this way, especially if it is a Fluffy Cloud Heaven (or Hell, for all of history's villains).
- Photo albums.
- The 50th Super Bowl, in 2016, began with a personal appearance of every previous Super Bowl MVP who was still alive and the NFL could get a hold of.
