Mario has a big adventure ahead as a new threat appears to take over the Mushroom Kingdom. Mario must defeat Dark Mario and his evil army of Luigi bots before they destroy everything that he has fought so hard to defend over the years. Things will soon get fired up in the Mushroom Kingdom.
For years, Mario has defended the Mushroom Kingdom from the likes of King Koopa(Bowser), and his Koopa Troopas. After Mario defeats Bowser once again, things finally start to appear peaceful. But Bowser will have none of that, still alive after being presumed dead by the Mushroom Kingdom, he continues to search for new and more effective ways to seize it. However, Bowser isn't the biggest and baddest thing out there. Dark Mario, an evil look alike of Mario, has been looking for years, for a chance at the Kingdom, with Bowser out of commission for a while, he seizes his chance. The dark figure walks down the hall of his castle, with his cape dragging behind him. He walks in to a room full of Mushroom people that he has imprisoned over the years to build his Luigi bot army. The time for building robots had come to an end, and the Mushroom men were no longer needed.
"Cease your labor!" says Dark Mario to his prisoners. "It appears, you Mushroom people have built me enough robots. You are free to go."
The Mushroom people were soon released by Black Yoshi, who was his right hand man.
"Black Yoshi, tell me. How do you take over a Kingdom?" said Dark Mario.
"Take out their leader?" said Black Yoshi.
"Over throw their leader" said Dark Mario. "Soon, the Mushroom Kingdom will be mine and Mario and his precious princess will both be a thing of the past! Awaken the Luigi Bots!"
Black Yoshi then throws the switch that turned on the Luigi bots, modeled after Luigi, Mario's brother. The Mushroom Kingdom was soon to be under attack.
Meanwhile on Peach Beach, Mario, Luigi, Peach, Daisey, Yoshi, and Toad were enjoying the sun. Wario and Waluigi were starting their own bomb shop, and Dr. Toadsworth was working on a top secret project.
"Im a number one!" said Mario as he and Luigi were racing their Karts across the beach!
"No Imma gonna win, Mario!" said Luigi as he made it two wide going into the turn, that led them into the town.
Luigi tried to control his kart, but he got loose due to being on the outside going into the turn. Mario then took the lead for the final time and won the race as he crossed the line.
Mario was celebrating his win, and Luigi came up to him to congratulate him.
"Good race bro" said Luigi.
"You did great Luigi. Just work on being on the inside in the turn and you will win too!" said Mario, before he took a drink from his water.
"Sure is hot out today isn't it?" said Luigi.
"Yes, it is. Perfect day for a swim!" said Mario.
Mario and Luigi then get back in their karts and race back to the beach. Once they got their, Peach already had all the food ready and Yoshi was starving.
"Alright! Ravioli, Macaroni, Spagetti, Lasagna! You sure know how to throw a picnic!" said Mario.
"Thanks!" said Princess Peach.
The gang eats their fill, and everyone is happy, even Yoshi. They then plan some fun on the beach. However, Wario and Waluigi show up.
"Say, would you like to buy a bomb?" asked Waluigi.
"No thank you, I don't use bombs" said Luigi.
"Come on!" said Wario.
"No! The war is over, and you will not be getting business from us unless you sell pasta" said Mario.
"Everyone has got to be a stinking critic!" said Wario. "You'll come around."
Wario and Waluigi go back to their shop to wait for customers.
Mario decides to go off by himself to look for special mushrooms. He looks around some rocks, and some pools of water. He then notices Luigi standing nearby, and calls out to him.
"Hey Luigi! Come here, I could use your help to find some special mushrooms" said Mario. Luigi made his way over to Mario. Mario looked around in pools and under rocks like he did before. He finally finds one, when he stands up to give it to Luigi to hold, he is surprised.
"You're not Luigi!" said Mario in horror, as he gazed upon the robotic Luigi.
"Luigi bot must get Mario, must get Mario!" said the robot.
Mario then runs before the robot can grab him. He then makes his way back to the beach where the rest of the gang is, only to see they were surrounded by Luigi bots. Luigi, Peach, Daisy, Yoshi, and Toad were all gathered up together, trying to convince the robots to leave them alone. Mario then grabbed a fire flower to power up.
"Alright you robots, prepare to get trashed!" said Mario.
Mario threw fireball after fireball at the robots destroying many of them. Hearing the uproar, Dr. Toadsworth drives a Mushroom van, built for multiple passengers to the scene to help them escape. The gang climbs in and takes off. Flying Luigi bots start shooting at the van.
"I'll have to drive this thing into a cave, they wouldn't think of trying to fly in a narrow cave. Should slow them down a little" said Toadsworth as he was trying to avoid the Luigi bots.
The ride is so bumpy that everyone is flying around in the van, because Toadsworth forgot to install seatbelts. Luigi lands right by Toadsworth's secret project, and slides under the covers as Toadsworth continues his attempt to make it to the caves. The attempt is successful, as the van makes it into a cave, and the Luigi bots crash into the outside of the cave. Toadsworth then brings the van to a screeching halt inside the cave. Luigi climbs out from under Toadsworth's secret project.
"Luigi, what were you doing under there?" said Toadsworth.
"I slid under here while you were driving" said Luigi. "What is this thing anyway?"
"Well, since you have discovered my project, I guess you deserve to know" said Toadsworth. "It's a clone machine, meant for an experiment of mine. However, I haven't got to test it yet."
"What was that green light that went off when I was under there?" said Luigi.
"Oh no! No, this can not be happening!" said Toadsworth as he looked under the cover. "Oh no, Luigi I'm afraid you have been cloned" said Toadsworth.
Another Luigi came out from under the cover, but he wasn't like Luigi very much. The only thing that matched was his clothes and his looks, but this new Luigi was on the stupid side and didn't match his personality.
"Duh, where am I?" asked the clone.
"Oh great!" said Mario. "We have a new threat on our hands and now we have to babysit a clone?"
"Be careful Mario, he's sensitive!" said Luigi. "I think I'll call you Tuigi!"
While Luigi was growing attached to his new friend, the rest of the gang began to wonder what they were going to do. They had a new enemy on their hands and they were going to have to make a plan.
"Toad, I need you, the princesses to take the vehicle and get as far away from here as possible. Toadsworth, I'm going to need you to come with the rest of us" said Mario.
"Toad, I need you to make sure that you keep the princesses safe, and do not let the clone machine fall into the wrong hands!" said Toadsworth to Toad.
"You can count on me!" said Toad.
Toad then fired up the van and drove off with the princesses and the machine. Mario and the rest of the gang would have to walk back on foot. Hopefully the Luigi bots had given up pursuit. Mario, Luigi, Yoshi, Tuigi, and Toadsworth were headed back to town to get an escape vehicle of their own.
Dark Mario had just arrived at the scene, and learned that Mario and the others had escaped. He walked along the beach looking at all the abandoned towels and beach balls that had been left by the mushroom people because of the uproar with the robots. Dark Mario surveyed the area and not a sign of Mario or Luigi.
"Black Yoshi, what is the report?" said Dark Mario.
"The robots report that a Mushroom named Dr Toadsworth had came and helped them escape after Mario disabled some of the robots" said Black Yoshi.
Just then Wario and Waluigi look through the window of their bomb shop to see what looked like Mario, dressed in black.
"What the heck?" said Wario.
"Must be a Mario imposter!" said Waluigi.
"Bomb time!" said Wario.
Wario throws a bomb out the window, and it lands by two of the Luigi bots and explodes them.
"What was that?" said Dark Mario.
Just then Wario and Waluigi come out of their bomb shop throwing bombs everywhere. However Dark Mario had something up his sleeve. With a wave of his cape all of the bombs are disabled and no longer usable.
"How did he do that?" said Waluigi.
"Unbelievable!" exclaimed Wario.
Dark Mario then approaches the two bomb happy brothers, and prepares to have them captured.
"Alright, get them now!" said Dark Mario as the bots surround Wario and Waluigi.
The two are then chained up and put on Dark Mario's ship as prisoners.
Not long after, Mario, Luigi, Tuigi, Yoshi and Toadsworth seek to find a get away van. They soon spot one. Toadsworth volunteers to go get it, but as soon as he steps out of the shadows, he is picked up by a flying Luigi bot.
"No, Dr. Toadsworth!" said Mario.
Some more robots come after the remaining four, but Mario and Luigi starts throwing fireballs at them, and Yoshi starts to swallow the robots and turn them into eggs, which he throws at the other robots. Tuigi, astonished by what he is witnessing tries to throw fireballs himself but instead of hitting the Luigi bots with them, he accidentally hits Mario, knocking him down.
"Tuigi!" Mario yells as he is almost grabbed by a robot, but Luigi intervenes and stops the robot from nabbing Mario.
Mario, Luigi, and Yoshi had finally beaten up enough robots to get away, so they along with Tuigi climb in the van and go after Toadsworth. Mario steps on the gas as they are on their way.
Dark Mario and the robots soon have Toadsworth in their possession as well. Dark Mario knew that Toadsworth could be a great prisoner to have because of his knowledge of machines, so he can make his robots stronger.
"You will tell me everything I need to know!" said Dark Mario. "Soon, I will be unstoppable, not even Mario will be able to compare."
Just then Mario and the rest of the gang drive up in the van to attempt to rescue the doctor. But they are too late, Dark Mario, Black Yoshi and Toadsworth were already loaded into Dark Mario's ship and flying away.
"Darn it!" said Mario as he hits the hood of the van.
"Who was that guy?" said Luigi?
"I don't know, but he looked an awful lot like me!" said Mario. "And the robots remind me of someone, but I can't quite put my finger on it."
"Me?" said Luigi
"No, let me think Luigi, you can have your guess next" said Mario.
"No, I mean…" said Luigi
"Luigi, please this is killing me I need silence!" said Mario interrupting Luigi.
Luigi then picks up a head of one of the destroyed Luigi bots and put it up to his face so Mario could see.
"Ooooooh, I get it now, they were designed after you Luigi!" said Mario.
Luigi slapped his forehead; Mario continued to ponder on who this guy was and why he was there. Yoshi had trouble keeping Tuigi from running off. Tuigi viewed all the robot body parts as toys, completely unaware that the robots look like him.
"Give me the toys, Yoshi, give me the toys!" said Tuigi.
"No, no, no! Stay put!" said Yoshi.
The clone would not listen, so Yoshi had to stick out his tongue and store Tuigi in his mouth for now. Mario, Luigi and Yoshi had a lot on their plate right now. Not only did they have Peach, Daisy and Toad to worry about, they also had Dark Mario plotting against the Mushroom Kingdom with his Luigi bots, Wario, Waluigi and Toadsworth had already been captured, and to add to the distress, they had to make sure that Luigi's clone, Tuigi didn't get into trouble! It was the start of one of Mario's most intense adventures ever.
"Hey Luigi, just out of curiosity, what does Tuigi mean?" said Mario as they all climbed back in the van.
"It's supposed to be a combination of my name and the word "TWO", making TUIGI! Clever huh?" said Luigi.
"Sure…" said Yoshi.
Mario and his gang set out to find out more about this new villain and how to rescue their friends, and hope that the princesses, Toad and the Machine do not get into Dark Mario's hands.
Hiding in the bushes, as Mario's van gets harder and harder to see as it drives off, Bowser had watched the whole scene unfold and is aware of almost every detail in the story. He sees this as a golden opportunity.
"Sounds like some competition. Soon, I will reveal my status as being very alive as I try to get in on this guy's plan. Finally, I will have revenge on Mario once and for all!" said Bowser.
