- In the Back to the Future fanfic Homecoming, the reason Doc is acting so strangely is leftover guilt and angst from thinking Marty had been hit by a train because he gave the incorrect time to set. When he saw that Marty was all right, he "wanted to forget the whole thing."
- In Hunting The Unicorn
Blaine: I'm not a virgin.
- In the eleventh chapter, the readers are subject to a reveal that does triple time as a "Funny Aneurysm" Moment and a Wham Line:
- There are several huge ones in With Strings Attached:
- The first comes when Jeft reveals to Shag and Varx that he, not the Dalns gods, was the force behind the Vasyn quest. He set the whole thing up just to see the four in action and ultimately to have them go up against his favorite gaming character, Jim Hunter.
- The second comes when everyone learns there is no curse on Ketafa—even Jeft believed it—and the gods could see the continent all along, but told everyone there was a curse on it so they didn't have to spend money “godding” it. The actual effect of the Vasyn is to end the reign of the Dalns gods and turn the planet over to the Pyar gods. Whether this is a Good Thing will be explored in the sequel.

Then, it's revealed she grew up on the streets, earning keep in Mad Moxxi's bar by slinging drinks, only later finding out that she was really the heiress to a massive family fortune. To her, this is a huge improvement. Needless to say, such a backstory screwed her up, badly.
- Pink Personal Hell And Altering Fate It becomes rather obvious later on that Nickel Steel is Dominic.
- The Writing On The Wall features this when the eponymous writing is finally deciphered at the end of the story, revealing the true nature of the Ancient Tomb that Daring Do and the other archaeologists had been excavating. It isn't a tomb at all; it is a nuclear waste storage facility built by humans. Daring Do isn't suffering from a disease - she is suffering from radiation sickness. The reveal changes the story from one about an Adventurer Archaeologist to a Science Fiction Horror story
This is not a place of honor. No great deed is commemorated here. Nothing of value is here.
- Pony POV Series has a few major ones in the Dark World Arc. For starters Fluttercruel was born Discorded and remained such until Sparkler's memories (when she Body Surfed into her) undid it, explaining why, unlike the rest of the mane six, she's essentially not matured in the last thousand years. Another is that Discord has spent the last several hundred million years trapped in a "Groundhog Day" Loop, always ending with his and Fluttercruel's demise.

The first few chapters give him a Sympathetic Pov behind him persecuting Vanellope, painting his actions as a Necessary Evil that he regrets having to do. Chapters one and two set up The Reveal as if it's going to be about King Candy's motivations for being so empathetic. Instead, there's an unexpected revelation about Vanellope as she crosses the finish line...
Because, standing where Vanellope used to be, is a grey-skinned, yellow-toothed maniac in a white and red racing uniform.
- Anthropology: Lyra spends much of the story trying to prove humanity's existance in Equestria.

- The Next Frontier makes the reader wait until nearly half-way through the story bewfore they find out what it's a crossover with, and there's absolutely no foreshadowing whatsoever. Intentionally so; it was intended to be a Shocking Swerve, but in a good way. Oh, and the crossover? Firefly.
- The Havoc Side of the Force has Harry Potter learn from Anakin that he wasn't accidentally sent into the distant future, but the very distant past. "A long long time ago" indeed.

Film — Animation
- Hans never really did love Anna and only wanted to marry her so he can marry into Arendelle, stage a "little accident" for Elsa, make himself look like a hero for bringing back summer and seize the throne.
- It never had to be a True Love's Kiss that would rescue Anna. It was just any act of true love, such as sacrificing yourself for your sister.
- Wreck-It Ralph:
- King Candy is Turbo in disguise.
- Vanellope is on her game's arcade machine, showing that while she is glitched, she is part of the official roster of her game and not just The Missingno.. This somewhat subtle distinction is important, and affects the plot greatly.
- The LEGO Movie: The entire movie has taken place in the mind of an imaginative boy named Finn, who snuck down into his basement to play with his father's LEGO collection. Lord Business is actually based on Finn's image of his overly strict father (aka "The Man Upstairs"), who insists on building a perfectly ordered LEGO world with no room for playing or experimentation.
- Big Hero 6: Robert Callaghan is Yokai, and Abigail was his daughter.
- Disney/Zootopia: Assistant Mayor Dawn Bellwether is the true mastermind behind a massive conspiracy to kidnap several predators, turn them feral using Night Howler pellets and ultimately, instigate a race war between predators and prey.
- The reason masked wrestlers used to be popular in 1930s USA wrestling and why mask vs mask remained a staple of Mexican lucha libre is that a good deal of the masked wrestlers never reveal their public identity until they are unmasked. El Santo never revealed his face until a week before his death. When a luchador is forced to unmask per stipulation, he/she also tends reveal much about their personal and professional history to the audience (as Konnan, turning him into a giant sympathetic baby face in CMLL.)
- The shocking revelation of the identity of the Outsiders' Third Man in WCW's 1996 Bash at the Beach: Hulk Hogan.
- The very long awaited reveal of the identity of The Undertaker's "higher power". It was revealed to be Vince McMahon himself all along.
- Or the true horrific reveal about Pro-Wrestling itself? It's scripted. Dun Dun Dun. GASP!
- In WWE, the man who drove a car and ran over Stone Cold Steve Austin at 1999 Survivor Series was revealed to be Rikishi, as well as the mastermind HHH.
- Can't wait to find out who the mystery RAW GM is in the WWE. Unfortunately, the Mystery GM was Put on a Bus and never mentioned again when Triple H took over as COO. Turns out it was Hornswoggle.
- Leading up to the 1990 Survivor Series, a giant egg was displayed at WWF shows and it was implied that the egg would hatch around the time of the card. During the show, Mean Gene Okerlund listened to the egg, said it was about to hatch and out came ... The Gobbledy Gooker, credited as one of Vince McMahon's stupidest ideas. He and Mean Gene danced for a little bit while fans booed. That same night, Ted DiBiase's team had a mystery member. After the rest of his team was introduced, DiBiase brought out his fourth man, a new WWF wrestler managed by Brother Love named ... The Undertaker.
- Back in the 1980's, Paul Orndorff was slated to face Don Muraco and Mr. Fuji in a tag team match at Madison Square Garden with a mystery partner. For a few weeks, Orndorff would do promos with a large cardboard box jostling around, saying his partner was inside. The week before the match, Orndorff used a power saw to cut the box open and reveal the Junkyard Dog.
- At the end of the Black Scorpion storyline in WCW, Sting defeated him at Starrcade 1990 and removed his mask to reveal Ric Flair.
- In Sophocles' Oedipus the King, Oedipus searches for the man who assassinated King Laius, only to find that he himself killed the king. As the seer Tiresias tells him, "You are the murderer you seek." This is one of Aristotle's examples of anagnorisis in the Poetics.
- A trope-worthy twist on the source novel turns up at the very end of the 2013 stage adaptation of Charlie and the Chocolate Factory: Remember the tramp at the junkyard, who met and conversed with Charlie at the start of the show and later encouraged the boy to buy that Wonka Bar that turned out to have the last Golden Ticket? He was Willy Wonka in disguise.
- The Ace Attorney series, being all about very dramatic trials, has some major reveals. Perhaps the most epic is in the second game's final case, where your client, Matt Engarde, turns out to be not the killer, but the man who ordered the killing. The reveal is so awesome because he smoothes back his hair to reveal some nasty scars on his eye, changing his appearance and expression extensively, and then he pulls a glass of brandy out of Hammerspace. In a holding cell.
- The homepage says "a buttload more informal than Wikipedia", so let's go with some more. The ending to the third game: even after Big Bad Dahlia Hawthorne has been defeated for good, there still isn't an actual suspect for the murder. After some further testimony and debate, Phoenix accuses Prosecutor Godot. What makes this a surprise is that so far there's been absolutely nothing to even suggest that person was anywhere NEAR the murder as it happened. But it's not out of nowhere; because the player has to prove they've actually been paying attention by answering "Who do you think the witness saw?" just before the Reveal.
- The first game's final case has two of them, in sequence. Lana Skye has already admitted guilt as your defendant, leading to a lot of suspicion as to: Why would you do that? When investigating a very obviously related incident referred to as SL-9, you must go through the testimony of her younger sister, Ema Skye, to find out what happened. Many players here expect this murder gives the proof and motive to put the real culprit behind bars. The result? You accidentally find proof positive to the real killer in that incident: Ema. This sets up for a bigger reveal later on.
- Throughout Ace Attorney Investigations the question we've been building up to is whether the Yatagarasu is Kay's father Byrne Faraday, as Kay claims, or Calisto Yew, as Yew claims. In the penultimate challenge of the game, it's told that the answer is neither option. The Yatagarasu was actually three people—Faraday, Yew, and Faraday's partner Detective Badd, putting their respective skills together to commit the thefts. Compared to that the reveal of the Big Bad is almost minor.
- The sequel to Investigations has, in its final case, the victim being the president of Zheng Fa from the very first case. The reveal is that he's actually a body double who formed a conspiracy with the killers of cases 2 and 4 in which he assassinated the real president and took his place. However, unlike the first game, the Reveal of the game's actual Big Bad - the one who masterminded the death of the body double, the first case's killer, and the capture of the body double's co-conspirators - is just as huge as the preceding reveal. It's Souta Sarushiro/Simon Keyes, the seemingly harmless clown you helped out in the second case and the supposed best friend of the first case's killer. Up until you have to deduce he's the mastermind, he never comes under suspicion, and the game needs to give you huge hints to his identity.
- In the final case of Phoenix Wright: Ace Attorney - Dual Destinies , it is revealed that the spy known only as 'The Phantom', who sabotaged the HAT-1 rocket, blew up the HAT-2 rocket and courtroom 4, and killed Clay Terran and Metis Cykes, has spent the entire game masquerading as Detective Bobby Fulbright, followed by the reveal that the actual Bobby Fulbright was killed before the game began.
- Dangan Ronpa: The corpse found in Chapter 5 is Mukuro Ikusaba's... except she's been dead for weeks now. She and Junko switched places for reasons unknown, and it was Mukuro who attacked Monobear in Chapter 1 and was killed for it. Her corpse was re-used to make it seem as though she has been recently murdered. And the person behind Monobear? The real Junko. Making this even funnier is the fact that the followers of the Something Awful Let's Play had been joking about Junko being the mastermind since the end of Chapter 3.
- Fate/stay night. In the Fate route Saber is revealed to be King Arthur (or Arturia), the Holy Grail is actually an Artifact of Doom Jackass Genie and that random priest at the very start is the Big Bad. In Unlimited Blade Works route Archer is actually a Future Badass version of Shirou. In Heaven's Feel route Sakura is Rin's younger sister who was given to the evil Matou family and was subjected to horrendous domestic abuse and Training from Hell for eleven years in order to become a vessel of the Holy Grail.
- Higurashi: When They Cry has Miyo Takano being the Big Bad, and the reason why there are so many arcs. There are other reveals though, but most are in the sound novels.
- The reason everyone goes crazy.
- Also for the viewer/reader (and Keiichi during Atonement chapter), the big reveal of unreliable narration during the question arcs. Go watch Onikakushi-hen knowing Keiichi is delusional and the girls really are just trying to help. So many little things suddenly make sense. Plus, Rika's dimension-jumping and Hanyuu's existence.
- Nine Hours, Nine Persons, Nine Doors has its first major reveal during the Safe Ending, where you find out that Ace is Gentarou Hongou, the CEO of Cradle Pharmaceuticals and the perpetrator of the first Nonary Game. Except he isn't Zero. Zero, as revealed by the True Ending, is June, and that you've actually been playing as her, not Junpei, the whole time. It Makes Sense in Context.
- And there are plenty of reveals in the endings of Virtue's Last Reward, but also a dramatic one that occurs when triggered as a result of player action. The first time you restore your game and switch route to change your answer in the Nonary Game, but your opponent also changes their answer, you might feel cheated; the second time, Sigma yells at them for cheating in-character, revealing that he's aware of everything you are, including restoring and restarting the game..
- Sekien No Inganock: Your name is 《Kikai》Porshion, one of forty-one unborn lives.
- EP7 of Umineko: When They Cry has the series' most important reveal. Basically, Lion is an alternate universe counterpart of Beatrice, who is also Shannon and Kanon. The person who all three of these personalities belong to is in fact known as Yasu, and their gender is unknown, which unlike most examples of that trope is actually a plot point brought up in the series itself. The game facts don't seem to apply, until you consider the fact that 17 people isn't clarified by multiple identities, allowing for a murderer to exist among a population of 17 fully recognized people.
- War: 13th Day builds up to these beautifully. First, with a healthy dose of Foreshadowing, it leads you to think that it's All Just a Dream. Then, you discover that it's not. Just wait until you reach the ending...
- There are several big ones related to the backstory in Avalon.
- At the beginning of the second year, Ceilidh finds out from Ryan that Joe, Alan and Phoebe were all friends until Helène arrived and took Alan away from Joe, then Phoebe started dating an abusive douche named Todd, who eventually dumped her and started spreading rumours that she was a lesbian, pushing her to the breaking point and causing her to beat him up. In the end, Joe never spoke to Phoebe again and while Alan came back to him after having had enough of Helène, their friendship was already damaged.
- Later in the same year, Joe eventually reveals that it was actually Alan who took Helène away from him, as Joe immediately fell in love with her but was too timid to ask her out, and Alan took advantage of that to make a conquest of her, reeling back when she wanted an actual relationship. He also reveals that it was him who caused Todd's injuries, pushing him down a set of stairs out of frustration and anger at hurting Phoebe, who he was also originally in love with. Afterwards, he simply never had the courage to go up to Phoebe and start their friendship up again.
- Even later, Phoebe tells Ryan that Joe actually asked her out, but she got scared and broke his heart, then got together with Todd because Joe going after Helène made her feel like he was lying to her before. She knew what he was like all along, he even physically abused her, but she couldn't bear to admit that she was wrong, and the whole experience just convinced her that nobody could care about her. This eventually lead to her lashing out at Ryan at the start of the actual comic, when he tried to help her.
- Bittersweet Candy Bowl revealed why Jessica and Rachel held so much animosity towards Tess. Lucy's confession to Mike is an in-universe example.

- Parodied in this strip from Dominic Deegan.
- At the climax of an earlier plotline of The Adventures of Dr. McNinja, it's revealed that every detail of the plotline was all part of an elaborate publicity stunt orchestrated by FOX News, or an attempt by a disgruntled weatherman attempting to keep his own report from being upstaged.
- YU+ME: dream - when the reader finds out that everything in Part 1 has been a dream.
- Mortifer, being more or less a Wham Series in later chapters, has plenty of these. The most notable, however, is chapter 18. William Aussek, Sam's Ensemble Dark Horse new CO, is actually Joey Von Krause in disguise. And Joey is actually a demon, with flame powers. And his eyepatch hides a gaping wound with a small light deep inside instead of an eye. And then he kills Sam, who's a viewpoint character. There are several other examples, such as the reveal that Vlademyre Hynner, Joey's old boss who was introduced in the first chapter, then forgotten, is the new leader of the southern black market, or the reveal that Badass Preacher Zebidiah is actually a demon under Vlad's control, or the reveal that Joey's hallucinations are actually Rashnu trying to get him to redeem himself, or the reveal that Joey's plan thee whole time has been to use his William Aussek identity to eliminate Sintec and the black market for good — more or less the opposite of what the audience thought he was planning, etc. etc. And what's better, all of them manage to make perfect sense in retrospect — well, except for the whole Zebidiah = demon bit.
- The Phoenix Requiem: The spirits are the bad guys.
- Homestuck: The most important character in Homestuck is... Gamzee Makara. Though, Lil' Cal may be more likely at this point.
- Also, Sburb's purpose is creating universes. And the trolls created ours.
- " YOU MADE AN UNBEATABLE BOSS IS WHAT YOU DID."
- The Tumor is what created the Green Sun. And Doc Scratch planned it all.
- The reveal of Lord English.
- The 06/17/12 update. UU's real name is Calliope. She will fall asleep and her brother will wake up if she hears her brother's name, and vice-versa. She is a Cherub, a species of sociopathic loners by nature, to the point that UU pretends to be a troll because she finds them preferable to her own species in every way possible. And finally, her face is shown. She looks like a young female version of Lord English.
- Reveals happen pretty often in Homestuck (see the Wham Episode page for more details), to the point where Hussie has a tendency to do it pretty anticlimactically whenever the twist was guessed by too many in advance. For example, in relation to part of the above-spoilered reveal:
But the fact that he's a slob was never exactly breaking news to anyone.Neither is the fact that you both share a body.
- In Impure Blood, Dara drops her knowledge on Caspian.
- Why is Yehuda Moon hated so much by Sister Sprocket? How did he get involved in the Kickstand in the first place? It's because he's a Soapbox Sadie, right? Actually, his work on a housing development inadvertently destroyed the forest, taking with it the Shakers' way of life with it. Selling their bikes is his way of paying penance.
- Ctrl+Alt+Del had a Running Gag involving Ethan trying to get into Scott's bedroom to see what was such a big secret that he spent most of his time there & refused to explain what he was doing, yet failing every time. And then, when he finally got inside by tricking Scott into leaving, he was stunned to find... a perfectly normal room, and got bitched at by Scott for the inasion of privacy, before Ethan accidentally knocked a lamp which opened a hidden panel in the wall hiding several computer monitors, with Scott's pet penguin, Ted, sat at them. Scott then explains they're going to release a virus that destroys all Microsoft software, because they experimented on Ted & Scott rescued him from the lab. Oh, and that made Ted super smart, and he developed a way to give himself telepathic control over Scott, with Ted being the dominant one of the two.
- Even better though - Microsoft probably wasn't responsible for the experiments. The only reason Ted thinks they are is because he saw the Windows logo on a nearby computer screen - and HOW many people use Windows OS?
- In Sinfest,
- morphE starts with two people in a cavern escaping from a madwoman with a knife and a second person. 115 pages later the reader sees a dream sequence which shows the cavern and one of the two escapees. Dead. The camera pans up and reveals Tyler, holding a bloody knife.
- In TOME, Zetto is really Kirbopher. And the leader of the hackers (alongside Kizuna), which would make Kirb the Big Bad if not for the double reveal that the hackers are not evil.
- Broken Saints has quite a few, but the most memorable comes in at the end of the penultimate chapter. Palmer is found dead, and in a storm of Mind Rape the face of the real Big Bad is shown. The hobo Raimi encountered by the alley, AKA, Lear Dunham.
- Ruby Quest has several moments that would qualify, but the biggest is probably "Today is october 31st".
- In Red vs. Blue's Reconstruction series, the fact that Church is the Alpha AI would definitely qualify.
- Another reveal in Revelation: Tex is destined to fail at every single thing she tries - no matter what she does - because that's what she's based on.
- Season 10 reveals that the AI Sigma used to belong to Carolina, and it was her decision to give him to Maine that set off the entire Recollection trilogy.
- The very end of Season 10 ups the ante by revealing that several major characters are in fact family, which dramatically changes the events of the previous 40 or so episodes.
- Season 12 has two for the price of one! First, Locus is working for a third party to kill everyone on Chorus. Second, Felix is revealed to be Evil All Along and working with Locus.
- Happens again in season 12 with the reveal of Control's identity.
- The finale of RWBY Volume 1 had a pretty big one, with Blake Belladonna accidentally blurting out her Dark Secret that she's a Faunas and a former terrorist, and her team-mates, most notably Weiss, trying to cope with the startling new revelation. They're able to resolve things in the end, by vowing to keep her identity a secret and making Weiss bury the hatchet. Worth pointing out that it got a lot of Foreshadowing and the fans (correctly, as it turns out) speculated it for a while.
- The biggest reveal in the Global Guardians PBEM Universe was the fact that Stone's mother was a supervillain, and that his father abandoned him at an orphanage in order to hide him from her.
- In the Whateley Universe, "Christmas Elves" has Fey and Generator in a trap, and they then find out that Don Sebastiano did not make Cavalier and Skybolt into his mind-slaves with his psychic powers but instead, Hekate did it with black magic.
- In If the Emperor Had a Text-to-Speech Device, the first episode of second season reveals that Kitten is actually the Captain-General, leader of the entire Adeptus Custodes. Played with in that it doesn't affect his status in the second season.
- In Wormtooth Nation, it's revealed that wormtooth gas, an invisible, odorless gas that causes permanent Easy Amnesia and has caused numerous problems for the protagonists, actually causes people to live forever in small doses. The entire population of the City moved down to the subterranean world in order to gain immortality, but after an unknown but presumably very long period of time everyone had been "nixed" so often that no one remembers this fact, nor the way back to the surface.
- Andria was really Magnum of Encyclopedia Dramatica the whole time.
- In Doom House, Officer Cop, who was initially thought to be a kind civil servant who is regarding Reginald's safety and well being as a top priority, reveals himself to be a terrorist who was only pretending to be a cop to try to get Reginald to leave the house so he could take it back from him.
- Marble Hornets Entry #35 reveals that the Masked Man who has been stalking Jay is Tim, one of the actors from Alex's film Marble Hornets.
- In Worm, Chapter 19.7 reveals that for the first sixteen entire story arcs, the main motivation for Tattletale's actions was to save Taylor from committing suicide.

- A recent arc on Cerberus Daily News involved a strange quarian signing up on the boards, causing everyone to suspect that she is actually one of the many psychopaths that used to frequent the website before the Reaper Invasion. But it's actually a volus trying to lure that quarian out.
- In Strange Aeons, Nick and Arron have been friends for at least a decade.
- In the second part of the last episode of Web Animation/Eddsworld , fittingly titled "The end", Tord is revealed to have had a secret bunker in his room where he kept a giant robot, which he proceeds to use in an attempt to kill his friends and take over the world. Not only that, but he's indirectly responsible for the events of both "The Snogre" and "Fun Dead". Kudos to the creators for putting in clues to both.
- American Dad! loves spoofing this. One example, from "The Phantom of the Telethon":
Stan: Give it up, Roger!
Roger: I'm not Roger, I'm the Phantom!
(Stan pulls off his mask and gasps.)
Roger: Well, yeah, I... what?
- My Little Pony: Friendship Is Magic: The 2-part second season finale, specifically the point where Cadence, who at this point has seemed to grow from a sweet, kindly foalsitter to a grade-A Alpha Bitch, is an evil fake in disguise.
- The Gargoyles episode "Future Tense" ends with the revelation that the Bad Future seen in the episode was an illusion created by Puck to trick Goliath into giving him the Phoenix Gate. He knew that Oberon was about to call the Children back to Avalon, so he wanted to get his hands on something valuable that he could use to trade for his continued freedom on Earth. To get it, he tried to convince Goliath that the worst possible future had come to pass, hoping that he would be scared into using the Phoenix Gate to travel back in time to reverse it.

- In the Futurama movie Bender's Big Score, the reveal is that Lars is Fry's time paradox duplicate.
- Three in Avatar: The Last Airbender.
- First one: Zuko and Azula's maternal great-grandfather is Avatar Roku.
- Second one: Azula for once, wasn't lying about something important. Ozai was going to kill Zuko to get the throne. However, their mother intervened and killed her father-in-law, somehow making the death look natural, and was banished because of it.
- Third one: the reason why Katara and Sokka's mother was killed was she claimed she was the last Waterbender of the South Pole, thus protecting her daughter.
- The comics are no slouch in this department. In The Search, at the end of the first novel, it is revealed that Zuko is not Ozai's son, but in fact Ikem's. But then Ursa reveals in the third that everything in that letter was a lie meant to mislead Ozai. Zuko really is his son.
- Scooby-Doo! Mystery Incorporated has a ton, relating to the show's overarching story arc about "The Curse of Crystal Cove".
- The biggest one, set up in the very first episode, is Mr. E's true identity. As revealed late in Season 1, he's really Ricky Owens.

- The Wacky Adventures Of Ronald Mcdonald, despite being a whimsical, lighthearted series of romps through McDonaldland, has a pretty big one for its' first video (which was somewhat Darker and Edgier than the other videos). The scary mansion is just smoke, mirrors, and holograms coordinated by a kid named Franklin, who's more or less lured Ronald's group into a big puzzle video game.
- Operation: Z.E.R.O.. has several, all within the same period of time; Numbuh 1's Bumbling Dad Monty Uno is in fact the fabled Numbuh 0, who founded the current Kids Next Door organization. Father, the series' Big Bad, is Monty's brother, Benedict Uno, Numbuh 1's uncle (Also making Grandfather, the special's Big Bad, Numbuh 1's grandfather).

- The biggest mystery was who wrote the strange journal that Dipper found in the woods (and the other two journals preceding it). In the season two midseason finale "Not What He Seems", we find out it's Grunkle Stan's twin brother, who had only been vaguely hinted about through background clues.

- The Justice League episode "Epilogue" contains a belated one for Batman Beyond, revealing that Terry McGinnis is Bruce Wayne's biological son, thanks to Amanda Waller subjecting his father to an experiment that secretly overwrote his reproductive DNA. Apparently, this was all part of a plan to create a successor to Batman by duplicating the circumstances that led to his birth; they even hired Andrea Beaumont to kill Terry's parents in front of him, though she got cold feet, and Warren McGinnis' later death was a coincidence.
- Steven Universe:
- The mid-season finale of season 1 has several reveals about the Gems: The Crystal Gems are not the last of their kind. All the monsters the Gems have been fighting are corrupted Gems themselves. And the biggest one: Gems are from space.
- On the Run explains why the Crystal Gems are so scared of Gems coming back to Earth: Gemkind as a whole are parasitic invaders, and attempted to suck the life out of the Earth. Amethyst is revealed to have been made in this manner.
