Chapter 1: Mario VS Sonic

Mario is seen running through the Mushroom Kingdom when he stops in front of a blue hedgehog lying on the ground who turns out to be Sonic. Sonic notices Mario and stands up before both getting into a fighting position.

"Bring it on!" yells Sonic.

"Here we go!" yells Mario as bloody five letter word appears on the screen and a deep voice says the words.

FIGHT

Sonic charges at Mario at lighting fast speed catching Mario by surprise and upper cutting him in the face causing Mario to stagger back a bit before looking down at Sonic shooting a fire ball at him which Sonic easily dodges.

But the fire ball was just a distraction as Mario runs towards Sonic and punching him in the stomach sending Sonic flying and landing on the ground.

Sonic gets up quickly and charges back at Mario preparing to punch him but Mario counter attacks with a punch which results in them only punching each other's fist.

Sonic then kicks his feet under Mario causing him to lose his balance but before Mario hits the ground Sonic brings his fist up causing Mario to fly up.

Sonic then jumps into the air and brings his leg down sending Mario flying towards the ground which results in him smashing into the ground causing a cloud of smoke to appear.

Sonic then charges into the smoke with his foot aiming straight down thinking Mario is laying on the ground.

Sonic gasps feeling his foot get grabbed as the smoke clears Mario is seen holding Sonic's foot with a look of anger on his face.

Mario then brings Sonic down onto the ground before picking him up and throwing him until he hits a warp pipe.

Mario then charges at Sonic, who is too dazed to react, and grabs him by the throat and repeatedly punches Sonic in the face until Sonic grabs Mario's hand and knees him in the stomach causing Mario to fall onto the ground holding his stomach in pain giving Sonic the opening to jump in and continually punch him in the face.

Mario then grabs Sonic's fist with his right hand then grabs his throat with his left before putting his left foot onto Sonic's stomach and the flings him backwards.

Sonic flies through the air and lands at the edge of the land where it goes into the ocean. Sonic seeing water jumps up and begins to back away not noticing Mario coming up from behind.

Mario then swings his foot under Sonic causing Sonic to lose balance but before he can hit the ground Mario grabs him by the foot and swings him around until letting go causing Sonic to soar into the ocean. Mario then gets his frog suit on and jumps in after Sonic.

Mario notices Sonic slowly sinking towards the bottom of the ocean and swims towards him and ramming him in the stomach causing Sonic to lose his breath.

Mario then continues to swim around Sonic and head butt him before swimming at Sonic and giving him an uppercut before swimming up back towards the surface.

Sonic struggles to breath and tries to swim back up but is unable to just as he was about to black out and idea came to his mind.

Mario comes out of the water and jumps onto the land and shoot's his hand up into the air.

"Ha ha ha I'm the be-" was all he could say before a blast of water shot up from the ocean causing Mario to fall down from the sheer force. He looks up to see that Sonic was golden he had turned Super Sonic!

Sonic then shot forward at Mario at a speed Mario was unprepared for and punched him in the stomach causing him to cough up blood and go flying up.

Mario the pulls a metal-looking mushroom out from his pocket and swallowed it turning him instantly into metal Mario.

Mario, being turned into metal, flew down towards Sonic and landed on him. Sonic unprepared for Mario landing on him was pounded into the ground until he was able to push Mario off of him.

Mario and Sonic stood staring at each other before Sonic made the first move and flew at Mario and punched him which did little effect.

Mario seeing Sonic's surprised face grabbed his arm before he could react and threw him behind him causing him to crash into a wall.

Sonic, starting to get angry, flew towards Mario and unleashed a barrage of kicks and punches which had no effect.

Sonic then grabbed Mario and flung him into the air.

Mario flew into the air as his mushroom wore off. Mario thinking quickly pulled out an over-sized mushroom and ate it.

Sonic saw Mario's mushroom wear off and stuck his hand up waiting for Mario to fall down. Sonic then noticed it getting darker he looked up to see a giant Mario heading straight for him.

Sonic moved out of the way just in time but was blown back due to the force. Sonic flew through the air as the chaos emeralds wore off and he noticed he was heading straight for a wall.

"No way!" yelled Sonic as he flew into the wall causing a cloud of dust to form.

Mario noticed Sonic crash into the wall and clapped his hands causing the force to blow the dust away revealing Sonic getting back up. Sonic noticed Mario running towards him and ran.

Mario started gaining on Sonic before Sonic boosted forward too far for Mario to catch up. Mario started shrinking back to normal size until he returned to his regular state.

Sonic turned his head and noticed that Mario returned to normal and took off towards him.

Mario, seeing Sonic speeding towards him, took out a flower and almost automatically it dissolved into his hand causing his clothes to turn white and his overalls to turn red. Mario waited until Sonic was a few inches ahead of him and shot a fire ball at Sonic.

Sonic being unprepared for the fire ball was hit and caught on fire. Mario grabbed Sonic and flung him backwards until he fell into the ocean again.

Sonic floated towards the bottom of the ocean again when he noticed what looked like a computer with a bubble on it. Knowing what it meant he spin-dashed towards it and destroyed it.

Mario, thinking he killed Sonic, was about to do a pose until he heard something come out of the water. He looked and noticed that Sonic had come out of the water in a bubble and just as he got out of the water the bubble wore off.

Sonic, beyond furious, ran towards Mario not as fast as he was before due to exhaustion. Mario noticed this and flung another fire ball towards Sonic who was far enough to dodge it easily. Mario then shot his fireballs at a great speed but Sonic was dodging all of them.

Mario, knowing that when Sonic hit him he would lose his fire flower, pulled something out from his pocket as Sonic sped forward.

Sonic, confident that this punch would finish Mario, flung himself at Mario and closed his eyes putting his hand forward. Sonic felt himself hit Mario but looked up to see Mario with light flickering around him. Sonic also noticed that his punch did nothing.

Mario then grabbed Sonic by the throat, who was too tired to resist, and squeezed causing Sonic to try and pry Mario's hand off him but failed to do so.

Mario then slammed Sonic onto the ground, with Sonic punching and kicking him to try and force him to let got but failed, as Sonic got weaker and was unable to fight back Mario's star power wore off but Sonic was to weak to even move as Mario made a bigger than average fireball and shoved it into Sonic's mouth and then covered his mouth.

Sonic's body shook violently before something happened. Sonic's head not having any air for the steam to go caused his head to slowly begin to expand before exploding.

Sonic's head exploding caused Mario to fall back from the force being to weak to resist it. Just then Mario's fire flower wore off as Mario stood up and shot his hand up in the air before shouting.

"Its'a me Mario!" he shouts into the air proudly as two letters appear on the screen as the same voice from before says the word.
