Edit: I also have no idea what to name this, does anyone have any ideas?
It’s more of a horror novel, and I have not finished or published it. I wanted to know if it belongs on this wiki once I appeal it, and I think it’s a unique idea for a game creepypasta, especially since the threat is the protagonist but is in deep denial about the depravity of his actions.
Here is the braindump of my ideas that I wrote so I wouldn’t forget the tone and direction:
A few weeks after Bowser’s most recent kidnapping of Princess Peach, and Peach’s subsequent rescue, things are settling down in the Mushroom Kingdom. Mario uses his computer to connect to fans of Nintendo games like the one they live in, he does not realize he and everyone knows are video game characters though, he assumes it’s an alternate universe situation, and it’s ambiguous which is the truth. The Nintendo fans an colloquially known in the Mushroom Kingdom as “Nintendos”. He discovers that people have been publicly making lewd comments about his brother Luigi, like they’re attracted to him. He is disgusted by this, as he views Luigi as his little brother, despite the fact that Luigi is only an hour younger due to them being twins.
He tries to ignore what he found, spending time with Peach, Luigi, and their friends. The next time he decides to go on his computer, he finds more of these comments about Luigi, and it feels like they’ve gotten more disgusting. The disgust and hatred he feels boils over when he sees two people swapping rather graphic fan-fiction about Luigi in the comments of an equally inappropriate post. His mental health begins to slide into oblivion, and after he turns off the computer, he leaves his house without telling Luigi why, gets an axe, infiltrates the world where these people are from, and hunts all of them down, killing them in increasingly gruesome ways, all the while remaining rather cheerful.
The reason for this joy he feels in committing mass murder of at least hundreds, if not thousands, of people is that his entire drive is protecting those he loves and doing right by them, being good is a core part of his identity and has been since he was very small. He is literally at his happiest when doing good, and can't comprehend that anything he does is wrong, because he has always been "the good guy.” He was happy while killing the Nintendos who lusted after Luigi because he believed he was protecting Luigi and doing right by him. This drive to protect and care for Luigi, combined with his anger and declining sanity, turned into a desire to see the Nintendos dead, although he cannot see how this is wrong.
He eventually returns home, covered in the blood of the dead Nintendos, cheerfully exclaiming to himself that none of the Nintendos who had lusted after Luigi were alive. He calls out to Luigi, exclaiming to Luigi that he’s home. Luigi comes to greet him, but is very scared upon seeing Mario covered in blood and wearing an axe. Luigi asks him what’s going on with the axe and the blood, and Mario explains that people had been lusting after Luigi, so he “got rid of them”. He tells Luigi that he’s safe now and that’s what matters, that he’d do anything to protect his little brother.
He sets the axe down and hugs Luigi, who freezes in fear, frightened by Mario having come home covered in blood, holding an axe, and apparently having recently killed countless innocent people. Mario doesn’t realize this, but to Luigi, Mario looks less like his selfless, kind brother, and more like a serial killer in Mario’s body. Mario, who is concerned by Luigi’s fear, asks him what’s wrong. Luigi lies that he just needs to get something, and runs out of the room.
Mario frowns, wondering why Luigi seems so scared of him. The thought that his brother is scared of him makes him sad. He thinks to himself that Luigi must just be scared of the blood, and so washes it off of his clothes and his face. He goes to check on Luigi, wanting to reassure him that everything is okay and the lustful Nintendos will never bother him again. He knocks on the door to Luigi’s room, asking him if he can come in, saying that he just wants to talk.
He hears Luigi ask if Mario will hurt him, and Mario reassures him that he would never do that in a million years. Luigi points out that Mario killed people and seems happy about it. Mario once again explains that his victims had been saying horrible lewd things about Luigi, and he just wanted to protect him. Luigi opens the door, pointing out that Mario had never killed anyone before, not even when Bowser kidnapped Peach. He tries several times to convince Mario that killing countless people is evil and way worse than what Bowser ever did.
Mario defends his actions, still in his mind’s self-made delusion that protecting his loved ones makes murder not bad, especially since he felt happy when killing the Nintendos in the same way he does when actually protecting or saving his loved ones. Luigi asks if Mario would be scared if he had murdered people to protect Mario, to which Mario responds that the idea of it was crazy and Luigi would never do that. He then realizes that that’s what Luigi had thought about him. He is horrified, realizing that what he did was wrong, very wrong, and that he would’ve never done it in the past. He anxiously paces back and forth without saying a word, his heart pounding, his mind alternating realizing what he had done and trying to rationalize what he had done, make himself think he was just protecting Luigi like a good big brother would.
He runs to the bathroom, feeling sick, and throws up in the toilet. He looks at himself in the mirror, thinking that he didn’t look like a killer, yet he’d killed so many people. He realized just how unstable, if not downright insane, he must be if that is the case. He was still the same on the outside. He still had that same iconic mustache, the same rosy red cheeks, the same red hat, overalls, and gloves. But on the inside, something was broken. It was so, so much worse than if he had completely changed. He still had that same happy-go-lucky smile, but it was a mask hiding something dark that lay deep inside.
He begins hyperventilating, his heart racing as he falls apart. His mind is falling apart, as is his sense of identity, as he did something evil, which the person he’s supposed to be doesn’t do. In his mind, this makes him evil, and in his mind if he’s evil, then he’s not Mario, he’s just a monster. He collapses on the ground, sobbing and hyperventilating, his heart pounding as he has a panic attack and a mental breakdown all at once.
He hears someone walk in. He can’t focus his thoughts or see them through his tears, but it’s Luigi. Luigi holds him gently until he calms down a bit. Luigi tries to reassure Mario that everything is alright, but Mario denies this, saying that he is a monster. Luigi does his best to calm Mario down, and Mario soon passes out from exhaustion due to his panic attack and breakdown.
Luigi carries Mario to bed before going to talk to Princess Peach. He tells Peach about what Mario had done, and she is horrified by his actions and worried about his sanity. They go back to Mario and Luigi’s house, finding Mario attempting to take his own life. Peach stops him, and he collapses into her arms, crying. Mario is committed to a mental facility, put in a straightjacket despite Peach and Luigi’s objections to the cruelty of such a thing, so he cannot hurt himself.
Over many months, he hardly changes, trapped in self-loathing except when his friends visit, convinced that he is no longer Mario and instead a heartless monster. One day, Peach comes to visit him. He seems happy to see her as always, with that lovesick puppy look that he gets when he looks at her. When he insists that he is a monster, she firmly tells him that he is not a monster, he’s just mentally unwell and needs to let people help him. Mario agrees to this, but for the sake of his friends’s happiness, not for his own benefit. The story ends with him promising to be good again.
