Ever since the moon incident, it was no secret that Mario and Peach were on unbelievably horrible terms. The red plumber let his pain, anger and sadness consume him and prompted his rash decision to abandon the Mushroom Kingdom forever. Everyone tried to persuade him to reconsider, but he wouldn't budge. He continued to shoot down their attempts to patch things up between him and the woman he thought cared about him. Mario put his foot down by screaming death threats to those that pestered him any further and that he hates the Mushroom Kingdom and everyone in it. This devastated everyone and so they instead sent him going away presents and cakes, but he indignantly threw them all away, thinking they were laced with poison, rigged with explosives and were traps meant to kill him. Once his house was empty, he drove his ship to a beach house on Bubblaine, where he spent his days doing nothing but relaxing, ensuring no one would push him away again. It even had a ten minute walk to a bakery, so Mario could always go there if he needed cake.
Peach had locked herself in her bedroom, the shades were drawn, so the room was dark. She was miserable after Mario cut ties with her, and so spent her days tearfully reminiscing through news and videos of the day their relationship came to a violent end, when she stole Mario's ship and tried to go home without him, the days that followed were plagued by angry exchanges, public acts of violence and even attempts of defamation. The princess even relieved the whole cringeworthy words he said to her before his departure.
"Goodbye, Peach! Goodbye forever, you ungrateful twerp!"
"For the last time, it was not my fault!"
Mario yelled, "My God! I can't stand any more of this! First you spurn me for yourself, and then you try to abandon me! You chew people up and then you spit them out again... I loved you... do you hear me? I loved you! And what did it get me? Yeah, I'll tell you: a big nothing. You're like a sponge. You take, take, take, and drain others of their love and emotion. Yeah, well, I've had enough! YOU WILL NEVER SEE ME AGAIN!"
"Mario, pleas-"
"SHUT UP, I KNOW! HAVING FEELINGS FOR A NASTY HEARTBREAKER LIKE YOU WAS A HUGE MISTAKE! I THOUGHT YOU CARED ABOUT ME!"
"But-"
"NO! GET OUT OF MY LIIIIIFE!"
He drove the Odyssey out of the kingdom as fast as he could, determined to be far away from his pain.
Toadsworth knocked on her door, "Princess? Would you like some food or water?"
"No thank you."
"Can I come in?"
"No."
He left, she kept looking at how things went horribly wrong, how Mario became a laughing stock on the internet, how he treated his friend's attempt to make him feel better only fueled the fire, how she only wished she could explain to him that she wasn't completely at fault, how different things would have been if...Bowser hadn't butted into their business that day and wildly derailed what would have been a very happy ending!"
Peach felt her blood boil, "Bowser! That BASTARD! This is all his fault! If only he didn't barge in when he did, he ruined my life!"
She rushed to all of her friends, Luigi, Daisy, Toad, Toadette, Yoshi, Birdo, Donkey Kong, Diddy Kong, Rosalina, Cappy, Tiara and many other allies to start a revolutionary rebellion against Bowser, she said to them all, "We're going to avenge the shame he caused us all! We're gonna stand up to him and make him feel the pain he put Mario and I through! We're going to take his life as punishment for turning Mario against those he cared about!"
Everyone cheered, they all gathered pitchforks, torches and even guns and knives and marched to Bowser's Castle, planning to give him what he deserved.
Meanwhile, in Bowser's Castle, Pom Pom was weeping over the loss of Boom Boom at his grave, the burly arm-flailer perished at the hands of the Broodals, who terminated him because Bowser stole their money as a way of getting a refund for the failed wedding, the rabbits have been trying to reclaim their wares ever since, but would sometimes claim the lives of some of Bowser's minions, including Goombas, Koopas, Shy Guys, Lakitus and others. The dead minons had their organs harvested and sold on the black market, Boom Boom's were sold as well. As the shuriken thrower mourned, Bowser Jr. was one of the few to actually comfort her when she needed it, which in turn may have caused Pom Pom to have feelings for him, in addition to other times that he saved her skin, despite how young he was.
Once at Bowser's Castle, Peach banged on the door, Bowser answered, "Princess, what's the matter now? Haven't I suffered enough, or are you here to marry me for real this time?"
"NO! You're what's the matter! Mario hates me and it's ALL YOUR FAULT! You are complete waste of space! You are a life destroyer that has a personality that rivals spore mold! On the evolutionary chart, you rank someplace between head cheese and toaster ovens! You're a cruise to nowhere! A null! A void! A zero!"
"Just what are you trying to say?
"ARRRRGH! I DON'T LIKE YOU! READ MY LIPS: I DON'T LIKE YOU!"
"Will you just go already? I'm in no mood to kidnappings if makes you happy."
"The only thing that will at this point is your head on my wall!"
Luigi said, "My brother no longer sides with us. He has become a lazy slacker and I can't take it anymore!"
Soon, everyone shared their disdain of Bowser and he reluctantly let them in to fight them all. However, Peach had a little surprise, she held Junior hostage when no one was looking and held a knife to his neck, saying, "If father won't play nice, maybe son will."
This made Bowser panic, "Let go of my son!"
Daisy warned him, "Only if you promise to stop kidnapping Peach and apologize to Mario for causing a rift!"
Peach restated, "I'm serious, do it or Junior gets it!"
Just as the battle got underway Pom Pom rushed in yelling, "STOP!"
Pom Pom said with an announcement of her love at first sight, how openly shameless of her love with Bowser Jr, "Please, don't hurt him! I love him!"
Everyone was surprised and a little weirded out, Peach asked, "Isn't he a little young?"
"I don't know, I don't care, there's no concept of age in the Mario canon, he could be 18."
Bowser Jr. was surprised as well, "You love me?"
"Yes. After all every time you helped me out of a pinch! Peach, put him down, there's something I need to explain to everyone."
Peach reluctantly released him, Pom Pom advised, "You all might want to get lawn chair or something to sit on, this story could take a while."
