Roy, Steve, Mr. Game & Watch, Popo, Nana, Female Corrin, & Emolga walked into the Mushroom Kingdom. Suddenly, Toad walked up to Steve.

"Sorry man, I'm gonna have to confiscate your Pokemon. Biosecurity and all." Toad said.

"Oh. Ok." Steve said.

The group leave Emolga behind.

"Mario universe, huh? Which fighter though?" Female Corrin asked.

"Who knows." Roy said.

"Hey-a!" Mario exclaimed. Roy turned to face Mario.

"This is my land!" Mario exclaimed. "Clearly there's only one way to settle this..."

Roy unsheathed his sword.

"With a kart race!" Mario exclaimed.

"W-What?" Roy asked.

Battle 64: Roy, the Young Lion, Steve of Minecraft, Mr. Game & Watch, the Master of Two Dimensions, Ice Climbers, the Bone-Chilling Duo, & Female Corrin, the Half Dragon vs Mario 'Jumpman' Mario A.K.A Mr. Video Game Himself, Princess Peach Toadstool the Princess of Toadstools, Princess Daisy, Sarasaland's Chipper Princess, Bowser, King of the Koopas, Iggy Koopaling, the Laughing Prankster, Morton Koopaling, the Enforcer, & Wendy O. Koopaling, the Bold Beauty

"Three!" Toad exclaimed.

"Why are we kart racing?" Female Corrin asked.

"Two!" Toad exclaimed.

"I... Have no idea." Roy said.

"One!" Toad exclaimed.

"Shut up and drive." Nana said.

"GO!" Toad exclaimed.

Mario, Peach, Daisy, Bowser, Iggy Koopaling, Morton Koopaling, Wendy O. Koopaling, Roy, Mr. Game & Watch, Popo, Nana, & Female Corrin took off in their karts. Meanwhile, Steve struggles to start the car.

"Damn! They're better drivers than I thought!" Mario said. Mario took a fire flower out of his pocket and ate it. He then shot some fireballs at Popo.

"WooAHAooohhh!" Popo exclaimed as he swerved out of control and crashed.

"Did he just... take out a fire flower?" Roy asked. "That's against the rules! He's only supposed to use items found on the track!"

"Clearly, he doesn't care." Mr. Game & Watch said.

"Fine then!" Female Corrin said. She stepped on top of her kart, transformed her arm into dragon form, and shot some water balls at Mario.

"Damn! My fire flower's doused!" Mario said. He took out an Ice Flower and ate it. He then shot some Ice Balls at Female Corrin, freezing her solid.

"Female Corrin! No!" Roy exclaimed.

"Two can play at that game!" Nana exclaimed. She drove right next to Mario and tried doing Blizzard, but Mario interuppted by transforming into a statue.

"Wha-" Nana began to say, before getting whacked by Mario.

"Mr. Game & Watch, it's just you and me left! Let's try to win!" Roy said.

"I already was, Roy." Mr. Game & Watch said.

Mr. Game & Watch passed an item block. He got a Blue Shell.

"I will now throw the Blue Shell." Mr. Game & Watch said as he threw the blue shell.

Mario looked back and saw the blue shell. He immedietly hit the brakes.

"OW!" Iggy Koopaling said as he got hit by the blue shell.

"Damn." Mr. Game & Watch said.

Mario drove through an item box, giving him a giant laser gun.

"Perfect!" Mario exclaimed.

"What the- WHAT?!" Roy exclaimed.

.

Meanwhile

.

Steve stepped out of the kart.

"Damn, how does this thing work? Ah screw it. I'll just run." Steve said as he drank multiple speed potions. With the effects overlapping, he is now super fast.

He then ran forwards, running past Peach, Daisy, Bowser, Morton Koopaling, and Wendy O Koopaling. Steve was so fast, he spun their karts out of control, destroying them.

"Ah, frick." Bowser said.

Steve looked ahead and saw Mario about to shoot Roy.

"Hey! Not cool, Mustache Man!" Steve exclaimed. He then took out his iron sword and striked Mario.

.

Popo, Nana, and Female Corrin walk up to Steve.

"Wait, we never finished the race!" Popo said.

"Who cares?" Nana said.

Mario stood up. "Mama Mia, what happened?"

"Galeem and Dharkon blasted everyone. I was the only one that escaped. Luckily, I found out that defeating the fighters controlled by Galeem and Dharkon would bring them back to normal." Roy explained. "With the help of my team, we've been able to free numerous people."

"Oh, snap!" Mario exclaimed. "That sounds serious. As Mr. Video Game himself, I gotta help."

Steve nudged Mr. Game & Watch. "Psst. Mr. Game & Watch, who's that?"

"Steve, that's Mario 'Jumpman' Mario, A.K.A Mr. Video Game himself! He's a gaming legend." Mr. Game & Watch explained.

"Oh." Steve said.

"Roy. Let me join your party." Mario said.

Roy nodded. "Alright. Let's go!"
