This is the plot. Anyone who is interested tell me here and maybe help me:
Enough with the Bowser kindnapping princess and Mario rescuing her cliche stuff. This time things are different.
We are in Marioverse, specifically in the mushroom kindom where Mario and Princess finally got married. Meanwhile, in Bowser kindom Bowser accepted the fact that if he continues doing the same stuff while never learning from his mistakes, history will just repeat itself, so he just gave up and found peace, got married with bowsette and made amends with the Mario brothers. The Wario brothers after being aware of the events with Mario brothers and Bowser, realised that they didn't have many differences with Bowser, this is why they decided to end their rivarly with Mario and Luigi as well. It was finally peaceful in the mushroom and bowser kindom. Heading to Yoshi's island, Yoshi after saying goodbye to Mario and Luigi finally headed back home to his family with his wife and kids, he had enough of the same repetitive adventures. This is why he decided to have a party with all of the locals on the island to celebrate the end of an era and the beggining of a new one. In conclusion, the Marioverse is finally at peace, everything is almost perfect for the first time. What could possibly go wrong... seriously.. what could possibly go wrong?
Now, we are in an unkown galaxy in an unknown planet far away from the mushroom kindom. This planet is populated with some weirldy looking creatures with a pink mushroom on their heads that look like toads but are not actually toads. This planet is dominated by Princess Shroob which is in the top of the shroob hirearchy. This alien is really hungry for power, so she decides to invade all of the nearby planets of the galaxy. Planet Cave, Planet Haunted and Planet Switch are all conquered by the princess. But her hunger for power doesn't finish there. Princess Shroob is also very smart, because she knows that the mushroom kindom is the only true challenge that will get on her way of conquering the whole Marioverse. She knows that if she invades directly Earth, will most likely loose due to her lack of power. That's when she finds an alternative to conquer the moon, build bases there and go as far as to conquer planet Mars as well. Her strategic plan seems to be working and if that's not enough, with the power she posseses now even created a new planet for Bowser, so she can bring him to her side, but Bowser now is mature so refused the offer. His kids though except bowser Jr did not, since they seem to got manipulated and brainwashed by the Princess so they allied with her thinking that Bowser let them down by not sticking up to his promises. And if you think that's too much, princess Shroob thinks she has enough power to merge the Marioverse with Sonicverse the Pokeverse and even the PvZverse into one universe and conquer it. The merge part was a success. That was the breaking point, where Dr. Eggman from sonicverse, Team Rocket from Pokeverse and Dr.Zomboss from PvZverse allied with Princess Shroob who has also created a new ally Dark Bowser. In addition an alternative universe, the kirby universe merged as well, so King Dedede and Meta Knight joined the dark side as well. This leaves us with the good side which includes the Mario and Wario Brothers, Yoshi, Bowser, Bowser Jr, Sonic, Knuckles, Pikachu, Ash, Crazy Dave and Penny the Machine. Princess shroob kindnaps Princess Deach and Daisy, Tails, Amy, Shadow, all of the pokemons in the Pokeverse including even legendary ones like mewto with the help of team rocket except Pikachu and Ash, and also kindnaps all of the plants on the PvZverse except the Sunflower and the Peashooter. That's when she finally invades the Marioverse.
