Story
In the opening, dark objects are fired at the earth from the very far space, these objects seem to be Fire Flower like objects. Those things are called the Comsluns, they're are a tribe of aliens that have disappeared in space a very long time ago. The leader of these mysterious aliens is the evil unpredictable Comslunitior. He is sending all of his minions to attack many kingdoms and take dominate them. His first target is the Mushroom Galaxy. We then see a small shinny book floating in Space, it gets shot by a cannon and falls to the Mushroom Galaxy.

Meanwhile in the Mushroom Kingdom, Mario, Luigi and Toadbert are looking for decorations in the attic for a party in Peach's Castle. They soon find a hole above a bookcase and Luigi investigates. Suddenly, Toadbert gets chased by a Scardey Rat, which entered the room through the hole, and leads it to Luigi, who starts to fight it. Suddenly being braver than usual. Winning the battle the Scardey Rat explodes and the bros celebrate the victory. But they are interrupted by a loud noise outside the castle. Mario looks outside and sees the same shinny book from the opening cutscene. It opens up and then tons of Paper cut-outs shoot from the book.

Meanwhile at Bowser's Castle, Bowser meets Paper Bowser, who, after some disagreements, team up together and agree to kidnap Peach and Paper Peach. Bowser Jr. also meets his paper counterpart, Paper Bowser Jr. and, unlike their fathers, the two become friends. Additionally, Kamek, Paper Kamek and Paper Kammy Koopa meet and shortly begin to insult each other, which continues throughout the game.

Back at Peach's Castle, we see Peach and Toadsworth having a conversation with Paper Luigi, who they think is the real Luigi. Mario, Luigi and Toadbert show up, and Paper Luigi freaks out when he sees Luigi, they do a little bit of a mirror dance to see if they're each other, which the other characters applaud to. Paper Peach then walks in and introduces herself to the others. Mario, Luigi and Paper Luigi agree to help Paper Peach find her servants and calm them down.

Mario and Luigi find the Paper people hiding in the castle. Afterwards, they explain that more of them were confronted by Goombas, however, a few were able to escape. The brothers go to the castle's workshop and discover a Bandit fighting two Toads and four Brocks, he is holding a bag and he dashes through them, Mario and Luigi tell them that they will use the two the Bandit left behind. While trying to leave the castle, they find Daisy and Toadette, who shows them two miniature papercrafts resembling Mario and Luigi. They then give the brothers a Copy Block.

At Toad Town, Mario and Luigi are greeted by two Goombas from the paper world, which they battle and crumple. After the bros defeat the two Paper Goombas, allowing the bros to access Goomie Farms where they are eventually cornered by a group of Comsluns, who defeat the Mario Bros. Paper Luigi decides to take them on himself but they pull out a space ship which charges up a lazar and kills Paper Luigi in the process. Shortly afterwards, Paper Mario arrives to defeat the Comsluns and save Mario and Luigi. After the battle, Paper Mario revives Paper Luigi with a 1-UP Mushroom and they reunite at last. While Mario and Luigi unite with Paper Mario, and the newly-formed trio set off to find the Paper people.

Soon after the meeting, the trio hear a big bang at Peach's Castle and see Bowser and Paper Bowser invading the castle, only to be stopped by a large line of Alien Space Ships, attacking the castle, however inside the castle we see Bowser and Paper Bowser punching and breathing fire on the aliens and heading into the throne room of the castle.

The Bowsers then arrive and return to their castle, calling Goomboss to attack the trio and slow their pursuit. After the group defeat Goomboss and he runs off, they eventually reach the exit of the farms and enter Clock-Head City, where we see a strange, purple house. The trio walk over to it Mario knocks on the door, no one answers, Mario knocks again and again, no one answers. Paper Mario tries to say something, but before he can, Mario knocks once again. Merlon opens the door slamming it into Luigi and Paper Luigi. He notices them and apologizes for slamming the door on them, they walk into the house. Toadley is inside, focusing on his crystal ball. Merlon and the Trio look in as well, and we see the Bowsers and their minions having a party.
