- Child of the Storm: In the sequel, Ghosts of the Past, Harry gets hit with this hard when he darkly remarks that he hopes the then unknown telepath who intervened to keep him at Privet Drive to study him comes around and has a go, doubtless planning to wreak horrors on his person. Then he does. Cue the Forever Red arc, in which Harry is kidnapped, tortured, his Blank Slate body is reprogrammed into the Red Son, the Winter Soldier's heir apparent, hundreds of deaths, countless cases of Mind Rape to varying degrees, the geopolitical map of the mortal and spirit worlds being turned upside down, and worst of all, the rise of the Dark Phoenix, an event which leads to more than a few mortals and gods concluding that Harry is an Apocalypse Maiden and too dangerous to live, while Harry is a slowly recovering traumatised wreck from the memories of 6 months of black ops horror. All in all, it's fair to say that that particular wish backfired.
- Thousand Shinji: Keel and the rest of Seele sought reaching Instrumentality to create a new god and become one with it. When Third Impact happened, it turned Shinji, Asuka, Rei and Misato -the four persons in the whole world who had suffered the most at the Seele's hands — into gods. And they were pissed off. Cue the Seele members receiving horrible, horrible punishments."You and the other members of SEELE wanted to shed your bodies and become one with a new god... well, no one ever said that God would be nice or particularly like you and your cronies for your involvement in its birth. I hope you prepared for the eventuality of an eternity being horrifically tortured by your worst nightmares."
- A Crown of Stars:
- When Shinji says he can not forgive his father and he can go to Hell, Daniel warns him about being careful about what he wishes for, since he can make it happen:"Be careful what you wish for around here, Shinji. If thats what you want, I can make it happen. I maintain and operate my own Hell, for those truly unworthy or unwilling to seek penance and redemption. And I know of even worse places than that."
- Kensuke wished he had a girlfriend, right like his friends. Then he met one girl was interested in him. Then another girl came along. Then both girls argued. Then they agreed to share him. And he has absolutely no idea of how handling the situation.
- When Shinji says he can not forgive his father and he can go to Hell, Daniel warns him about being careful about what he wishes for, since he can make it happen:
- In "A Simple Wish," Chi-Chi carelessly wishes herself out of existence. After seeing how the world has drastically changed without her, she comes to regret the wish.
- Children of an Elder God: Shinji wishes to be a god during a dream, thinking it was just a silly dream. Later on, he gets godly power, but he doesn't like it because it corrupts him and gradually turns him into a Humanoid Abomination.
- Constants and Variables: When she realizes that Elizabeth is much more complex and mysterious than she seems, Narcissa invites her to tea to talk politics. When Elizabeth finds out that she drugged her with veritaserum, she decides to tell her the whole truth, sending them into an alternate world where Voldemort wins. Narcissa seeing the calamity her familys loyalties will bring certainly puts things into perspective for her.
- In Miraculous Ladybug vs. the Forces of Evil, Marianette and Adrian wished they could have something new and exciting in their "routine" lives. Well they got it when Star Butterfly and her enemies came to town, and all the consequences that spring from this lead to some dark places for the two.
- Neither a Bird nor a Plane, it's Deku!:
- Overlapping with Gone Horribly Right. Bakugou constantly berates Izuku on his hypocrisy due to his refusal to be a hero, and wishes he'd apply for the U.A. so they can properly settle their score. A series of events eventually get Izuku to retake his dreams, and when he does, Bakugou demands that he trains for the entry exam because there's no way he's getting in after a whole decade of inaction. Izuku ends up taking that advice to the point he walks away with the highest entry score ever in the history of the UA, surpassing even All Might himself. Worse, he quickly becomes The Paragon and inspires other students to help each other, knocking Bakugou down to the bottom of the Top 10 ranking. As a result, on the first day Izuku quickly becomes the Big Man on Campus while everybody takes a dislike to Bakugou and some even make fun of him for his score, as well as the Sludge Villain incident.
- Izuku and the premise itself are an example of this. Izuku wanted nothing more than an amazing Quirk so he could be like All Might and was devastated when he was declared Quirkless. He got his wish when his Kryptonian Super Strength and Nigh-Invulnerability manifested not long after he got home. Unfortunately, he's a four-year-old with powers he doesn't understand. So when he gets into a fight with Bakugou, he accidentally throws Bakugou into a building across the street, which nearly kills Bakugou and leaves him grievously scarred for life. Then Izuku slowly starts developing more powers than he knows how to deal with, including Super-Hearing that's so intense that he passes out after listening to every bad thing happening around the world at once. Then he learns that the reason why he has his powers is because he's an alien. His Earth happens to be plagued with anti-alien hysteria. He certainly hit the Superpower Lottery, but it came with a boatload of angst he wasn't prepared for.
- Cycles Upon Cycles: After Joker's boast that he could make the Normandy dance, Shepard tells him to be careful about saying such things as he just may need to do that someday.
- Every chapter of Guardians, Wizards, and Kung-Fu Fighters closes with a narrative quote from a character, usually reflecting some theme from that chapter. In the case of Chapter 20, which is the one where Cedric finally tells Elyon the truth of her identity and takes her to Meridian, the quote is Elyon reflecting on how she used to dream of someone coming to tell her that she's a really a long lost princess, as that would mean she's special... and how the worst thing that ever happened to her was that dream coming true.
- The Halloween Unspectacular anthology series has a few examples:
- In "Wolf", from the fourth edition, Timmy accidentally comments on how cool it would be to be a werewolf where his fairies can hear, turning him into one.
- In "Timmy Turner's House of Terror", from the seventh edition, Timmy wishes for the ghost of a famous person he can interview for a history project. But because he wasn't specific about who he wanted, he got stuck with Lizzie Borden.
- In "Come and See" from the eighth edition, the Devil tempts Gaz with a pocket watch that grants seven wishes, with just two catches. First, every wish cast unlocks one of the seals of the Apocalypse, but with the caveat that Gaz herself won't be directly affected, which she's fine with. Secondly, which she's not aware of until it's too late, is that upon all seven wishes being granted, the Devil claims Gaz's soul.
- In the Facing the Future Series, much like in the cartoon, Desiree works with this trope until she finds love with Sidney Poindexter.
- Hellsister Trilogy: During his wedding, Clark Kent surreptitiously makes Lois' bouquet land on Supergirl's hands; a subtle way to wish her good luck in finding a steady boyfriend. Next time he saw her, Kara had hooked up with Dev-Em, a former pain-in-the-ass bully whom he loathes.
- With This Ring: In "Contingency" OL complains endlessly over the sloppiness of Martian Manhunter's training scenario, he complains that it's uncreative and unrealistic because the Justice League in it act very uncharacteristically. He definitely gets his wish for realism.
- Dragon Ball Abridged:
- Gohan points out this trope in his nerdish way after he and Krillin realize the recently-revived Piccolo was brought back to Namek... on the other side of the planet from where they are standing.Gohan: Oh, so it's a sort of monkey's paw. You have to be careful with the hubris in your wishes.
Piccolo: (in the distance) NEEEEEEEERRRRDDD!
- Krillin wished for the perfect Christmas tree. Shenron delivered. Thanks for the special, you two!Reject Mall Santa: Turles, sir! Our ship has mysteriously changed course for a new planet: Earth!
Turles: Does it contain the sufficient amount of joy?
Reject Mall Santa: According to our sensors... yes!
Turles: Well, then... merry Christmas!
- Shenron snarks this trope again when Garlic Jr. wishes for immortality. It's almost as if he knows how badly this will end.Garlic Jr.: Dragon! Make me immortal!
Shenron: Oh? R-really? Wow! Can't remember the last time someone nutted up and asked for that! Congrats! Can't wait to hear how you f**k this up.
Garlic Jr.: What's that supposed to mean?
Shenron: It means YOUR WISH HAS BEEN GRANTED!
- Gohan points out this trope in his nerdish way after he and Krillin realize the recently-revived Piccolo was brought back to Namek... on the other side of the planet from where they are standing.
- In A Jealous Wish Goku, after seeing Oopa's joy at having his father back, wishes to Shenron to have his own father back. An Affably Evil Saiyan who could destroy all life on Earth in a matter of hours if given reason (assuming he doesn't just blow up the planet) and has no idea of what's going on beyond the fact the son that in his visions would defeat Frieza has wished him back to life and isn't anywhere near strong enough to take on the monster that will come to try and murder him. Surprisingly, the only victim so far is a doctor whose mutterings gave Bardock the impression he was too incompetent to be allowed to live.
- Meg's Family has the chapter Time Stew. Stewie, after having a dream that Maddie will stop his plans of world domination, goes back in time to prevent Maddie from being born by making it so that Meg and Zack never met. Of course, Stewie realizes just how much he cared about Maddie and tries to get her born again. This goes to hell when after getting Meg and Zack (Whose married to Nikki in this timeline) together, Zack ends up murdered and Meg kills herself afterwords. Brian even says this trope word for word.a
- In Winter Is Coming Along With Ideas, Rhaegar gets his wished second daughter for his "three-heads of the dragon" prophecy from his love, Lyanna Stark. Unfortunately while Rhaegar survives to become king and put down the rebellion, Lyanna dies in childbirth and his wife and son are killed. He spends the story repenting for his actions and taking care of his daughters, Rhaenys and Joanna.
- Cersei Lannister gets to marry the man she always wanted, unfortunately Rhaegar hates her because her father killed his wife and child and only married her because she was only one close to his age. She also has no Jaime to take comfort in because Jaime was banished to the Wall.
- The whole premise of Wish Carefully boils down to this. In this Alternate Universe Fic, after Dumbledore dies, Harry decides to let the Death Eaters get what they want (no more Muggleborns, no contact with the Muggles, full control over Magical England, all of their enemies out of the way), but instead of being able to revel in their apparent victory, Lucius Malfoy eventually realizes that their wishes have actually condemned them to a slow and painful death. He actually mentions the trope, and calls it trite.
- Another Harry Potter fanfic had Harry, unable to finish Voldemort off because he hid one Horcrux too well and unwilling to let him continue killing, put Voldemort in stasis for millions of years: Voldemort awakens at a time when all of humanity has left Earth, and the Sun is glowing so hot that the planet's surface is almost scorched. In the end, Voldemort notes with irony that he got his wishes: he will live forever (or for so long that it will seem so), he will rule a world that is empty of most other life and he will be the most powerful wizard in the world because he is the only wizard in the world.
- Prodigal Son: When the parents of the village try to retract their children from training because Astrid sided with Hiccup (then under the name Prometheus), viewing her as a traitor, Astrid makes a point by having the incompetent and narcissistic Snotlout to take over for her. What follows is Snotlout trying to bully the students into a total offense attack on a monstrous nightmare all the while the terrified parents try and salvage the situation, Astrid's training advice being the only thing keeping them alive.
- In The Boy Behind The Mask, Snotlout wanted to be chief and the people of Berk wanted an heir that exemplified good old viking machismo. Unfortunately, Snotlout had no idea how boring and hard it would be to be the next chief and the people of Berk don't like the fact that their future chief is a self-righteous idiot, the current Chief and Elders having little to no faith in him.
- In the fanfic Gaz Dreams of Genie, Gaz gets hit with this after accidentally freeing the genie Azie from her lamp and being granted Three Wishes in exchange. She wastes her first wish with a Freudian Slip (expressing her annoyance with Dib by saying she sometimes wishes he'd never been born), leading to a Villain World where Zim rules and she's a slave; she then has to use her second wish to hit the Reset Button. Left with only one wish, and specifically being told she can't wish for more, Gaz spends time contemplating every wish she can think of, and realizes that every single one could theoretically backfire on her. She tries to employ some Loophole Abuse by wishing for the power to grant her own wishes (thus allowing her to tailor things her way), but this just leads to her and Azie switching lives, leaving Gaz trapped in the lamp.
- Kill la Kill AU: In Comic 41, we have Ryuuko, in light of Satsuki's illness, and she wishes to be the "sick one" instead of her then ill sister. Unfortunately, this comes true and the comic ends with her in the hospital as her illness gets worse. In the second part of that arc, Satsuki wishes to be the sick one, too, so Ryuuko won't be alone
- The Outside seems to imply this, as Ryuuko wanted little more than to go outside. She does get to but, unfortunately, this costs her the life she had before, as her getting injured it the reason she's removed from Satsuki's care altogether.
- In Love Hina: Like It Could Have Been, Naru and Makoto successfully drive Keitaro away from the Hinata Inn, meaning they don't have to deal with a male manager.

- The Curse of Beauty involves a story within a story about six pony princesses, each named for a fairy tale heroine, who each recklessly used a spell from a magic tome called "The Excess Magic of Wishes", with disastrous and ironic results: Princess Snow White wishes she weren't so tall, and shrinks to a tiny size; Princess Goldilocks wishes to be more "sensitive", and suddenly everything feels too hard or too soft, too cold or too hot, etc.; Princess Rapunzel wishes for a longer mane, and ends up with enough hair to swamp a tower; and so on. Princess Cinderella "merely" gets trapped in a giant pumpkin after losing her concentration while casting a powerful spell.
- A Future of Friendship, a History of Hate: Episode 5 is built on this trope — Scootaloo, tired of the downsides of being a kid, accepts Miserain's aid in becoming an adult... only to figure out pretty fast that she has no idea how to be one, getting her into all kinds of trouble, eventually leaving her completely depressed. Which is what Miserain wanted, as Scootaloo's despair fed the woebeghoul sealed in the Tear of Covet. Once everything is over and done with, Scootaloo learns the episode's Aesop about waiting to grow up.
- The Pony POV Series has this as the origin story of General-Admiral Makarov. The Hooviet Empire was struggling to stay afloat after the Dragon-Hooviet War (which ended with the Dragon's leader Queen Tiamat Curbstomping their entire military and leaving half the empire blazing ruin) and sought to create the Ultimate Lifeform to enable them to lead them back to greatness. The resulting Super Soldier experiment created Makarov. The good news? He's doing exactly what they wanted him to do. The bad news? He's playing his leaders for pawns and has his own goals of world domination. Made more literal by the fact he's actually a Equineoid Abomination called the Shadow of Chernobull created by Pandora and imprisoned in her box. A Hooviet experiment with an imagination engine ended up releasing him from his prison, after which he fed off their desires and wishes to become Makarov, in the process eating the existences of countless deer and threatening the entire world.
- The Reading Rainbowverse has Bonbon being a bit annoyed that Lyra isn't taking their relationship seriously... and then Lyra finds out how Bonbon feels and breaks up with her, thinking that she can't return the affections.
- No Maturity Here, a short comic, shows Fluttershy getting upset by Discord's pranks and demanding of him, "Act your age!" As it happens, saying this to a Reality Warper that is millenia old isn't a wise thing: Discord takes an undead form as starts terrorizing Ponyville.
- An episode of My Little Pony: Friendship Is Magic has Twilight cast a spell on the parasprites, little creatures who are eating all of the food in Ponyville, to stop them from eating the food...which then leads to the creatures eating inanimate objects such as buildings. In one fanfic, Twilight thinks the spell through and casts a spell to stop the parasprites eating food and inanimate objects. Unfortunately, this leads to the parasprites now developing an appetite for the ponies!
- In the same fanfic, when Twilight stops to think about the spell, she remembers that she cast the spell on a roommate of hers (back in Canterlot) to stop her from eating desserts to assist with a diet. While the friend did stop eating desserts, she then started eating lots of spinach instead, which led to her passing lots of gas.
- Played for pure Nightmare Fuel in The Conversion Bureau: The Other Side of the Spectrum side story The Last Train From Oblivion, where Rio Deneter, a member of the PER, wanted nothing more than to be rid of her Dark and Troubled Past and she was convinced ponification would solve all of her problems and take the pain away. Rio does get her wish to become a pony granted, but given the nature of how the conversion process goes, she quickly regrets her decision but it's already too late for her. What happens next is a Mind Rape so thorough that even when Rio tries to fight it, she just loses more and more of herself until she's nothing but a hollow mockery of a pony with no free will or sentience.
- Advice and Trust: Asuka wanted to show everybody that she was the best pilot, and she wished that Shinji got her blatant hints. At last Shinji got her hints and because she became more psychologically stable -thanks Shinji- she became the Number One, and she and Shinji defeated an enemy together... but because they did not win as Gendo wanted, he fired them, rendering her accomplishments irrelevant.
- Evangelion 303:
- Asuka wanted to get the B-1C assignment. After doing a bit of soul-searching and bonding with Shinji she managed to become the chief test pilot for the experimental jet... and she was not happy because Shinji got to leave for one week as she got to stay to take part in the program. And during the assignment she had to put up with a harsh (albeit well-meaning) drill instructor while wearing an embarassing suit.
- After a crash sends Asuka into a coma for several months Shinji spent the entire time desperately praying for her to wake up. She did eventually recover, but was an absolute mental and emotional wreck due to the trauma; becoming angry, spiteful, and lashing out at him constantly. For Shinji, this was like going from one hell to another, and sometimes made him wonder if this was what he had been wishing for. Fortunately she got better.
- HERZ: Kensuke wished being an Humongous Mecha pilot. He managed becoming a jet fighter pilot, which it is almost so good in his opinion but it entails that Asuka is his superior officer, and they never got along well.
- In The Second Try, Shinji and Asuka were sent back in time because of an offhanded wish they made one night. They got their wish, but it came with a heavy cost. They wished that they could do something to allow their 3-year old daughter a normal life; a life where she could have friends. By going back in time they got their chance to make such a world, but it also erased their daughter from existence. Shinji doesn't take this very well when he learns of it. Ultimately averted when it turns out she was sent back as well, but to a later date than her parents.
- In Neon Genesis Evangelion: Genocide, Misato wanted that her ward Asuka had enough free time to recover from her latest physical and mental wounds. Then her Humongous Mecha went berserker, hurt another pilot, and Ritsuko considered to fire her.Ritsuko: However she sees it is not really relevant. I do find it ironic that you were so concerned for her having some time off and now it bothers you that after next week she won't be required to pilot again. In essence, you have gotten just what you set out to get.
Misato: Be careful what you wish for, right?

Then he recognizes the voices/names on the broadcast and realizes exactly which island they're destroying— The Judicial Island, Enies Lobby, which is one of the Marines' three greatest strongholds. It's also lampshaded by Cross during the broadcast almost immediately afterwards.Cross: We're going to take a leaf out of the pages of the big black book of piracy! Only... It's not the edition you were hoping for. We're tearing this straight out of the Four Emperors' personal playbook: you touch one of ours? We fuck you up.
- Jabra taunts Luffy in hopes of getting the best possible fight. Unfortunately for him, he did so by not only pressing Luffy's Berserk Button, but slamming it with a sledgehammer. No-Holds-Barred Beatdown ensues.

To add insult to injury, Akane gives Akari her Hyperspace Mallet, and Happosai vows to give Ryoga's female form all his attentions.
- Averted and played straight on separate occasions in Irresistible when Yukari Sendo manages to purchase a Monkey's Paw with two wishes left on it. Yukari, having researched the magical artifact and knowing it's potential for backfiring, wished to be "Tsukune's dream woman" and is turned into an older version of herself who knows exactly how to become Tsukune's woman. Gin, knowing nothing about the artifact except that it can grant wishes, wishes for there to be more girls at Yokai Academy. Since the Monkey's Paw lacks the power to create life, it simply turns all the boys at the academy into girls (barring Tsukune whose heritage makes him immune).
- Blake in In the Kingdom's Service spends some time wanting to figure out why Jaune is acting so suspicious. Ever since learning he's an agent in Vale Secret Service and, despite her fears, wasn't investigating her at all, she's wished she had just minded her own business since now she has another secret to keep and this one might get her killed.
- In Fist of the Moon, Sailor Moon Rei Hino is very bossy and tends to snipe at Usagi's leadership skills. Then they have to split the team, and Usagi leaves Rei in charge. The fiery girl is panicking about potential attacks and catastrophes less than an hour after Usagi leaves, because she can't bear the thought of disappointing her leader...it's lampshaded by another character that while Rei likes to be in charge and opinionated, the responsibility of leading is too much for her.
- A variation of this trope appears in this discussion in the Empath: The Luckiest Smurf story "Under The Cat's Paw".Brainy: You honestly think your praying is going to change the nature of the beast, Tapper?Tapper: I only know that the Almighty is capable of anything, Brainy, including changing your heart and your mind so that you will believe He is real.Tapper: Be careful of what you ask for, Hefty Smurf.

- In a "what if?" Yu-Gi-Oh! fanfic called Isn't It Grand What I've Managed to Do?, Pegasus beats Yugi during their duel, claims Yugi's Millenium Puzzle, and then uses the Millenium Items to bring Cyndia back to life, just as he wanted. However, before he brings her back, he is warned both by Shadi and by the pharaoh's spirit that although he will find what he seeks, it will end badly for him. He doesn't care, and resurrects Cyndia anyway. No, it's not a monkey's paw twist; she doesn't come back as a zombie or anything. In fact, at first, everything goes smoothly. Pegasus has Cyndia back the way she was before, and they make the most of their happy reunion. So why does "be careful what you wish for" come into play? Because as we know, Pegasus had to steal people's souls in order to pull off the resurrection...which Cyndia discovers. She then becomes absolutely furious that Pegasus would murder people to bring her back to life, and tells Pegasus to his face that she barely recognizes him, that she hates him, and she doubts he really loves her at all if he would treat her like a lost possession to be brought back at any price. This causes Pegasus to wish he had never brought Cyndia back to life; he would rather have her dead and loving him than alive and hating him, and he has a humongous My God, What Have I Done? moment. They do eventually reconcile when Cyndia, recalling Pegasus' childhood refusals to follow the rules, manages to forgive Pegasus...but Pegasus has to fake his own death in order for him and Cyndia to be able to live happily together.

In an effort to make the brother reconsider and show how effective the bomber could be, Reborn has Gokudera guard Tsuna.

Worse, his boss doesn't even bother treating him like a person, referring to him as a dog more than once. Gokudera realizes too late that he left Tsuna, a person who honestly cared for him and treated him like a friend, for someone who treats him no better than a pet.
- When All Your Dreams Come True, a horrifyingly plausible Avatar: The Last Airbender fanfiction, in which Zuko's dream of catching the Avatar and being reinstated as his father's heir comes true... and promptly turns into a scene so nightmarish that he eventually loses himself in increasingly desperate daydreams trying to wish the new reality away.
- Based off To Love-Ru, this darker fan fic, "To-Love-DEATH" has an element of this. When the alien Gruello kills Princess Lala, Rito freaks out and immediately regrets wishing his life away. Although his panic attack is cut off short when Gruello enters his chest cavity.
- The Big Bad in Warriors of the World: Soldiers of Fortune fully possesses someone who asked to become the strongest because the villain is the strongest there is. The poor victim gets consumed for his troubles.
- Sonic X: Dark Chaos has some particularly disturbing examples, most of them combined with a Deal with the Devil. Venus the Seedrian wished for the power to kill Tsali and prevent the destruction of her race. Not only did she fail to save her people, but her wish doomed her to slowly turn into a robot and damn her soul forever. Tsali made a similar wish for the power to get revenge on the Seedrian race for what they did to him. He got what he wanted - at the cost of his soul, sanity, and the utter destruction of most of the galaxy.
- From The Legend of Total Drama Island:
- During the dodgeball match, after the hard-throwing but very wild Tyler hits the referee with his first throw, Eva says, "Not bad. Now let's see if you can hit an actual player."

- D.J. invokes this trope by name after Ezekiel, against whom D.J. bears a grudge, has apparently fallen to his death.
- During the dodgeball match, after the hard-throwing but very wild Tyler hits the referee with his first throw, Eva says, "Not bad. Now let's see if you can hit an actual player." When Tyler, throwing from the back line, hits a teammate with his next throw, Eva invokes this trope.
- An example both in and out of universe came from Super Smash Stadium. The SP Metal Man spent quite a while trying to be named head of the site. He did achieve his goal after every other person running it had moved on to different goals. In-universe, this left him with a Stadium so badly wrecked, he had to move to another dimension and run that one. Out of universe, Metal and his new staff were not as good as they thought they were, leading to Dead Fic status.

- Early in the Chip 'n Dale Rescue Rangers Fan Fic Rhyme and Reason, Chip is disappointed with the cases the Rangers have had to solve so far. They're nothing compared to what his idol Sureluck Jones has to deal with in his novels. Since his birthday is coming up soon, he wishes for a really big and challenging case to solve. What he gets — before his birthday already — really stretches his "no case too big" rule. And he can't even turn the case down because it's up to solely him to find and rescue his team mates from certain death (and stay alive himself despite the perfectly timed attacks against him) until sundown.
- Frequently occurs in the All Guardsmen Party. Arguably the result of Sarge's promotion - sure, their superiors are no longer insane, but they have worse assignments now.It was the complete opposite of all the horribly complex ops we'd suffered through since joining the Inquisition: it was the ultimate simple, straightforward plan. If it wasn't for the fact that we'd be outnumbered thousands to one, we'd have loved it. As it was though, there's no word for how much we hated that plan.
- In The Royal Protector both Marco and Brittney get hit by this hard. Marco wished for more fun and excitement in his life and Brittney wished for him to get sucked into a dark abyss in a fit of anger, cue Star casting a Summon Everyman Hero spell at that moment and everyone blaming Brittney for Marcos disappearance.
