A/N: This story was sent in at a different site, which has Bowser's father known as "Morton Koopa Sr." and Wart as Bowser's brother. Mario and Luigi are also generally, idiots. I hope this answers a few questions.
Chapter One: A Deal
Mario and Luigi were off on another adventure to rescue Princess Peach. It was simple and the enemies were easy to take care of. Once they arrived at Koopa Castle, they took some easy, straight-forward paths they remembered from previous adventures and made it to the throne room of Bowser, King of the Koopas.
"So, you've finally made it," said Bowser.
"Yup-a, and now we're-a going to defeat you again!" said Mario.
Mario and Luigi ran toward the Koopa King, but Bowser wasn't planning a fight.
"Stop it, you idiots!"
Mario and Luigi came to a stop and looked confused. Why did Bowser want them to stop? They both had the same thing on their mind: they thought he was telling them to stop to trick them. But before they were able to take another step, Bowser started talking again.
"So, you want the princess back, eh? Well, here's the deal…"
Mario and Luigi listened.
"I want these cool gemstones known as the Ancient Gems. I've got this little piece of paper that has pictures of them. Here…"
The Koopa King handed the two plumbers a piece of paper. Three gems, a Sparkling Ruby, a Sparkling Emerald, and a Sparkling Diamond were seen.
"That's what they look like. I want them, and I'll return the princess if you find them and give them to me," said Bowser.
"We can't-a trust you," said Luigi.
"Sure ya can. I swear, if you find these Gems, I'll hand over the princess. Then the Mushroom Kingdom will be back to normal. And if I don't keep my promise, you can defeat me again. So, is it a deal?"
Mario and Luigi looked at each other and turned their heads back to Bowser. They nodded.
"Good, good. I think one is in the Mushroom Kingdom, another is in Dinosaur Land, and another is in Sub-con. Go that?" asked Bowser.
"Yep-a," said Mario.
"Good. Now, get your ugly mugs outta here and find those Gems!"
Luigi stuck the paper in his pocket and the two Brothers left the castle. It did not occur to them that this was a part of Bowser's plot.
"Hahaha! Those stupid fools!"
