Mario and Sonic - Icons Clash (Redo)

Because I'm in the mood,I've decided to flesh-out my 2 Mario/Sonic XOvers, Mario and Sonic - Icons Clash and Mario and Sonic - Legends Clash. I'm gonna start with Icons Clash and then in the next post,will redo Legends Clash. 

Anyway,here we go.

The story begins sometime after Mario and Luigi smashed Bowser's quest for World Domination and rescued Princess Peach once again. A day later,Bowser,Kamek and Bowser Jr. are going on a routine tour of their Koopa Kingdom.when they spot something strange that they've never seen before - A Gold Pipe.  The trio of bad guys go in to investigate it.

Kamek knows of this Pipe and explains that the Gold Pipe is a special pipe that appears randomly every year and that each pipe can lead to a different Universe. Curious,Bowser Jr. wants to know where the pipe leads and enters it,despite some warnings from Kamek. Seeing that they are choiceless,Bowser and Kamek go after Bowser Jr. The Trio of baddies end up in the Egg Empire Zone,home of Dr. Eggman's current Base in the Sonic World.

As the Koopas wonder where they are,they are being spied on by one of Dr. Eggman's robots. At his base,Dr. Eggman and his lackeys,Cubot and Orbot,are watching the Spy Robot's video feed and are curious about who and what these strangers are? So he sends his Robots to capture them,so that he can interrogate them.

Bowser,Kamek,and Jr. destroy the Robots,which forces Eggman himself to interfere. Dr. Eggman confronts the Koopas and demands to know who they are and why have they "invaded" his Empire? Bowser asks if those Robots that attacked were his? Eggman tells him that they were and that he sent them to capture and interrogate them,but it looks like he'll need to do that himself. This ignites a verbal fight between Bowser and Dr. Eggman,which escalated into a psychical one.   

Bowser's strength and the ingenuity of Eggman's Mega Eggmobile. Both take a moment to complement each other's abilities. Dr. Eggman asks Bowser again about who he is and why is he here? The Koopa King introduces himself,Kamek,and Bowser Jr. and that they came though a Golden Warp Pipe from his Koopa Kingdom. Dr. Eggman is curious. He mentions that he's seen 2 before,but completely dismissed them,thinking that they were just fancy colored pipes. 

Bowser and Co. are surprised to learn that there is a 2nd Gold Pipe? Dr. Eggman asks Bowser to show him the Pipe he and his entourage came though? Dr. Eggman,forgetting his manners,finally introduces himself and his Zone.   

The Koopas lead Dr. Eggman to the pipe and explain it's function and origins. Dr. Eggman is impressed and is curious to see where the pipe leads. Bowser uses the Warp Pipe to take Dr. Eggman to his Koopa Kingdom. Eggman isn't too impressed,but does appreciate the gloomy and hellish atmosphere.

Bowser tells Dr. Eggman that if it wasn't for Mario,the Great Hero of this World,his Kingdom would've been the entire Galaxy. Dr. Eggman knows the feeling,as he has his own Heroic Arch-Nemesis - A Speedy Blue Hedgehog called Sonic.

Dr. Eggman and Bowser talk about their Nemesis's and decide to help each other out by conquering their respective Worlds for each other as a token of their new alliance. And then they can bridge the Worlds using a Giant Warp Ring,which he'll create once he completes his Chaos Energy Generator,But that unlike The Gold Pipe,the Warp Ring will remain forever.

Bowser agrees to the idea and asks Eggman to show him that 2nd Gold Pipe. Dr. Eggman says that he found it just miles outside Station Square in his Universe and takes Bowser to it. Moments Later,Bowser and Dr. Eggman drop out of a Gold Pipe and into a strange and seemingly deserted World somewhere in The Mario Universe. This is where that 2nd Gold Pipe took them.

Bowser wonders where they are? Dr. Eggman doesn't really know,but what he Does know that it seems secluded - a perfect place to work in peace. So the 2 decide to make this World their shared base of operations. 

Dr. Eggman says that his Chaos Energy Generator will need the Chaos Emeralds,he's also gonna need them for his new Death Egg,which will be built here. Bowser even though he likes the name "Death Egg",since they're working together,the new Death Egg should have a look and name that combines their attributes.

Dr. Eggman agrees to this. Bowser and Eggman christen their discovered land - The Koopa-Egg Zone. Hours later,Dr. Egman and Bowser had brought their forces to the Koopa-Egg Zone and are working on the New Death Egg,which will be equipped with a Chaos Energy Generator,a generator that will help the villain duo create their Giant Portal Rings.

1 month later,the New Death Egg and it's Chaos Energy Generator is complete. This new Death Egg is shaped like a Spiked Koopa Shell turned right-side up,with Dr. Eggman's face. Inside is an amalgamation of Dr. Eggman's Bases and Bowser's Castles. The Emblem is even a combination of Bowser's and Eggman's.

They call their newest base the Death Koopegg. For the next part of their plan,they are going to need the Chaos Emeralds,which are located in the Special Zones in His Universe. When Dr. Eggman is showing Bowser what the Chaos Emeralds are,Bowser comments on them looking more like Beryl. Dr. Eggman explains that even though,by themselves,the Emeralds hold great power,when the 7 Emeralds are united,they can bring miracles to those who possess them.

Bowser tells Eggman that they need those Emeralds,but need to keep their enemies in the dark about what they are up to And they'll need some better "help" to retrieve these things from the Special Zones. Dr. Eggman has an idea - recruit the Friends of Sonic and Mario and have the 2 Main heroes fight it out,blaming each other for their friends kidnappings,while their friends are doing their dirty work. 

The King of the Koopa's loves the idea and has got the perfect Spell to turn them. But Dr. Eggman wants to robotizise them instead,this leads to a brief argument. Kamek tells the duo that since they are helping each other conquer each others Worlds,why not execute both methods - Robotizise Mario's Friends and Koopa Kurse Sonic's. The 2 Tyrants agree and shake on it. 

Meanwhile,with Kamek's help,Metal Sonic captures Princess Peach at her castle,while leaving a note. He then heads to Sarasaland to capture Princess Daisy. He then captures Wario,who's on a treasure raiding expedition. Next he captures Yoshi and Donkey Kong,who were relaxing on their respective islands. He then captures Luigi,who was working in the Sewers of the Mushroom Kingdom. He then captures Toadette,who's treasure hunting. And finally Metal Sonic captures Waluigi,who was doing nothing in particular.  

At the same time this was happening,Bowser Jr.,as Shadow Mario,and the Cosmic Mario Clones kidnap Amy Rose at her home,Knuckles on Angel Island,Shadow and Rouge during one of their missions for G.U.N.,Tails at his home workshop,and Team Chaotix at their HQ.

All were captured behind Mario and Sonic's backs. As all of this is going on,Sonic is racing through Emerald Hill Zone as exercise,finding it weird that Eggman hasn't caused any trouble for a month and a half and begins to wonder if something is up?

Sonic then comes across a Flicky,who tells Sonic that a character fitting Mario's description has kidnapped Tails from his workshop and and that the kidnapper was heading toward Green Hill Zone on South Island. Sonic races toward Green Hill. The Flicky turns into a Pidgit,who contacts Bowser and tells him that the Hedgehog has taken the bait.

Meanwhile back in the Mushroom Kingdom,Mario is searching for Princess Peach at her castle. Toadsworth and Toad tell Mario that Peach has been kidnapped by Kamek and a Blue Hedgehog,possibly a new recruit of the Koopa Troop. He shows Mario a note left by the Kidnappers which also reveals that they've taken her to Green Hill Zone,which can be accessed by a Gold Pipe outside of the Castle. 

Mario leaves to find the Pipe. Toadsworth wishes him luck.

Back at the Death Koopegg,Dr. Eggman robotisizes Mario's Friends. Bowser has objections about robotisizing Peach,but Dr. Eggman assures him that He'll revert her back to normal once their jobs are done. Despite all of this Bowser is impressed with Eggman's Robotisization technology.        

Bowser then puts the Koopa Kurse on Sonic's friends,turning them into vicious feral-looking slaves of the Koopa King. Dr. Eggman is impressed by Bowser's magic. After the 2 pat each other on the back they send their minions to get the Chaos Emeralds. Though they have Kursed Tails and Mecha Luigi stay behind. Dr. Eggman tells Mecha Luigi that he wants him to broadcast the Big Fight between that Plumber and the Hedgehog. Bowser tells Kursed Tails to make trouble for the 2 heroes,should something come up between them. Both bads tell their servants to stay hidden out of sight.

Mario reaches the Gold Pipe and enters it,leading him to Green Hill Zone in Sonic's Universe. Sonic spots Mario and the confrontation begins. Mecha Luigi and Kursed Tails arrive in secret and Mecha Luigi begins the broadcast. 

Sonic asks Mario what he did to his friend? Mario has no idea what Sonic's talking about and asks where He and Kamek took the Princess? Sonic has no idea who this Kamek is and asks again where he took Tails? Mario tells Sonic that he doesn't know any Tails and that he's no kidnapper.

Sonic has heard enough and attacks Mario,Mario counters Sonic's attacks with his own. As Mario and Sonic fight,Mecha Luigi is broadcasting it to Dr. Eggman and Bowser,who are enjoying the show. Mecha Peach and Kursed Amy return with the White Chaos Emerald. Dr. Eggman takes it and puts it in the Death Koopegg's Power Generator,which is located in the next room.  

Mario and Sonic continue to battle throughout Green Hill Zone. Sonic is impressed that Mario can almost keep up with him. Mario is impressed that Sonic can take a hit. The 2 eventually fall into a gold pipe embedded deep in the ground. 

Dr. Eggman and Bowser order Mecha Luigi and Kursed Tails to follow them. Mecha Wario and Kursed Shadow return with the Yellow Chaos Emerald. The Kursed Chaotix team also return with an emerald - the Blue Chaos Emerald. Eggman and Bowser are pleased at the quick progress of their minions. 

Meanwhile,Mario and Sonic have been warped into a City. But not just any city - New Donk City. The 2 are now in Mario's World. Sonic confuses it with Station Square at first,but Mario corrects him and the fight continues.

Back on the Death Koopegg,As Eggman is putting the recently acquired Chaos Emeralds in the Generator,Kursed Rouge and Mecha Waluigi deliver the Purple Chaos Emerald. And immediately after,Kursed Knuckles and Mecha Donkey Kong return with the Red Chaos Emerald. Bowser happily comments that there's only 2 more to go - the Cyan One and the Green One.

Sonic and Mario battle all over the City,ending up on the rooftops. The battle is a stalemate and Sonic demands to know where he took Tails. Mario tells Sonic that he's still got the Wrong guy and demands where He and Kamek took Princess Peach. Sonic tells Mario that he has no idea what he's goin' on about. 

Mario suddenly takes out a Fire Flower out from his overalls. Sonic wonders what's with the flower. Mario uses turns into Fire Mario and begins to shoot Fire Balls at the speedy Blue Hedgehog. Sonic is able to dodge - but barely.

Back on the Death Koopegg,Dr. Eggman is amazed that Mario is so resourceful. Bowser tells his partner that He doesn't even know the half of it. Mecha Yoshi and Mecha Daisy arrive with the Final 2 Chaos Emeralds,the Green and Cyan ones respectively. Eggman is super pleased and leaves to put the them in the Generator. Bowser tells himself that Phase 2 of the plan will be commencing soon.

Back in New Donk City,Mario and Sonic are still fighting on the Rooftops. Sonic makes Mario lose his powers. Just then from the corner of their eyes,our Heroes spot their onlookers. The 2 stop fighting for a moment to get a closer look at them. The recognize them as Luigi and Tails. Mario looks at Kursed Tails and sees the Mark of Bowser on His forehead and realizes that Bowser has placed a Koopa Kurse on the young fox. While Sonic realizes that Luigi has been Robotisized...The trademark work of Dr. Eggman.

Dr. Eggman contacts Mecha Luigi and tells him that Phase 2 of their plan is about to begin and to return to base for preparations. Mecha Luigi tells Kursed Tails that they will return to base now for Phase 2 of the plan. The 2 modified heroes rush off. 

Mario and Sonic finally figure out that they've been set up by their archfoes. After a bit of a cool-down,the 2 finally introduce themselves. After that,they give chase to their corrupted friends. They catch up with them and chase them into a Portal Ring,where they end up in the Koopa-Egg Zone.

Sonic and Mario get distracted by the Death Koopegg,which allows Mecha Luigi and Kursed Tails to escape. After taking some potshots at the Death Koopegg's design the 2 press forward towards it. Dr. Eggman and Bowser,though a loud speaker,taunts Mario and Sonic and reveals their plan and it's progress.

Dr. Eggman activates the Chaos Energy Generator and the Death Koopegg fires out a beam that creates 2 Massive Warp Rings,one that leads to the Koopa Kingdom and the other that leads to the Eggman Empire Zone. Eggman gloats at the Greatness of The Chaos Generator. He then escapes though the Koopa Kingdom portal with his Robotisized Mario Minions. 

Mario is shocked to see all of his friends and the Wario Duo turned into Robots. Bowser and his Koopa Kursed Sonic Pals attack Mario and Sonic. Sonic is angry that Bowser has "warped" his friends. The Koopa Kursed minions are too much for Mario and Sonic to handle,especially since they just came off of a tough battle with each other. The 2 tired heroes are knocked out.

A few minutes later,the 2 awaken and Bowser and his Kursed Minions and the 2 portals are gone. Sonic figures out that Bowser likely escaped to his World,since Eggman escaped to Mario's. Mario and Sonic decide that before they can assault the Death Koopegg,they'll need to save their friends first. Mario has an idea on how they can do it.

Moments later,after traveling through multiple Gold and Normal Warp Pipes,the 2 arrive at Boosette Woods in Mario's World,which was a creepy forest. Sonic even comments on it. The 2 come to a building,this is the Laboratory of Professor Elvin Gadd.

Mario and Sonic tell Prof. Gadd about the current situation and,luckily,he has the solutions. Prof. Gadd gives Mario his newest invention - The De-Robot Buster,an Arm Cannon that can De-Robotisize. He then gives Sonic a Silver Ring that can break Any Koopa Curse. He also tells them that both devices can detect the Transformed from miles away.

The 2 thank Prof. Gadd and head toward the Mushroom Kingdom,where the Gold Warp Pipe to Green Hill Zone is. The Reach the Pipe and after wishing each other luck,Sonic departs for his world with the Curse Curing Ring. Toad runs toward Mario and informs him about Eggman's assault on their World and that he spotted a robot that looks like Luigi going into the Sewers of the Mushroom Kingdom and if does damage,things will be disastrous. Mario is on his way.

Meanwhile,Dr. Eggman and Metal Sonic has made a temporary residence out of Bowser's Castle and Eggman complains on how hot it is. He then reveals that He likes Bowser,regardless and intends on Robotisizing the Koopa King and making him His 3rd-in-Command of his Expanded Eggman Empire and that with Mecha Bowser and Metal Sonic,Both Universes Will be His.

Back in Sonic's World,Bowser,Jr.,and Kamek are hanging out withing Dr. Eggman's base. Bowser has a hard time working Dr. Eggman's machines and tech. Bowser thinks Eggman is a genius and intends to add him as the Koopa Kingdom as the Chief Scientist,once the he,the Koopa King,overtakes Both Worlds and even Both Universes.

As all of this is going on,Sonic arrives at Green Hill Zone,where he sees the entire Zone being destroyed by an army of RoBirdo,who's got some Goomba's,Snifits,Fire Chomps,and Flying Cheep-Cheeps with them. After taking care of them,he is confronted by Kursed Amy.  

After a bit of a battle,Sonic uses the Silver Ring to cure Amy Rose,turning her back to normal. Amy Rose is happy to see Sonic. Sonic ask Amy where the others are? Unfortunately,Amy can't remember a thing since she and the others were captured. Sonic tells Amy not to worry about it and that he'll figure it out Himself. 

Meanwhile,inside the Sewers of the Mushroom Kingdom,Mario is fighting some Motobugs,Crabmeats,and those Robofly enemies from Sonic 2. After dispatching them,he fights Mecha Luigi. Mario equips the De-Robot Buster and fires it at Mecha Luigi,turning him back into Normal Luigi. After a small reunion,the 2 set off to find their Robotisized friends.

Back on Sonic's World,Sonic and Amy arrive in Emerald Hill Zone,where they see it being destrpyed by Montey Moles,BubBuns,Trouters,and a new recruit to the Koopa Troop,Dookey Kong,a monkey that throws mud. Leading this group is Kursed Tails. Sonic comments that Kursed Tails looks even creepier than the Tails Doll. After a short battle,Tails is hit with the energy from the Silver Ring,returning him to normal.

After a brief reunion,Sonic,Amy,and Tails head to Angel Island. Back in Mario's World,Mario and Luigi are in Sarasaland facing off against Mecha Daisy. Luigi tries to reason with her,but it fails. Mario fires a Blast from his De-Robot Buster at Mecha Daisy and turns her back to normal.

After a reunion,the Trio head for Yoshi's Island to find Yoshi. Dr. Eggman,Metal Sonic,and Mecha Peach (and Cubot and Orbot) are watching the events via Spybot. Eggman is annoyed and admits that Mario is more resourceful than he realized. He contacts the rest of his Robotisized Mario Minions to be on their guard and to avoid being hit with Mario's Arm Cannon. Mecha Peach asks when her turn is coming. Dr. Eggman tells her to be patient and it will come soon - provided that Mario isn't destroyed by the time he makes it to the Koopa Kingdom. 

Back in Sonic's World,on Angel Island,Sonic,Tails and Amy are battling a gang of Dookey Kongs,Dino-Rinos,Pirana Plants (especially the venus fire traps and patooies),and Wigglers. All lead by Kursed Knuckles. After defeating every minion,they fight Kursed Knuckles. The fight begins and Kursed Knuckles overpowers everyone. But Sonic outsmarts him and uses the Silver Ring to turn him back to normal.

After some banter,Sonic wants to save the Chaotix next. Knux tells Sonic to try Isolated Island,as the Trio hangs out there a lot during their off-days. So the 4 head to Isolated Island. Watching from afar is Kamek,who is in a panic and leaves to warn Bowser. 

Back at the Eggman Empire Zone,in Eggman's Base,Bowser and Bowser Jr. are finally learning how to work Eggman's machines. Kamek rushes in and warns Bowser that Sonic has got an Anti-Koopa Curse Ring and is undoing the Koopa's work. Bowser knows that Sonic got that Ring from Prof. E. Gadd and is angry. He tells Kamek to telepathically alert the rest of his Kurst Krew and to Get That Ring Away from that "Annoying Hedgehog". Bowser then wonders how Dr. Eggman is doing?

Meanwhile,in Mario's World,on Yoshi's Island,Mario and Co. are fighting a gang of Dinosaur Badniks lead by Mecha Yoshi. After dispatching the Badniks,Mario,Luigi,and Daisy battle Mecha Yoshi. Mario uses his De-Robot Buster to return Yoshi back to normal.

Yoshi is happy to see everyone. Luigi asks where the other Yoshi's are? Daisy tells them that they likely ran and hid during the attack. Mario informs Yoshi that they must save their Friends from Dr. Eggman's influence. Yoshi understands and joins his friends on their mission. Meanwhile,Sonic,Amy,Tails and Knuckles are battling the Kursed Chaotix on Isolated Island. Sonic Uses the Ring to cure Charmy first,then Vector,then Espio. 

After a brief conversation,the Chaotix agree to help Sonic and Co defeat Bowser. Back in Mario's World,Mario and Co. are rushing through Castle Mario in Mario Land to get to Mecha Wario. They battle various Badniks from the Sonic Game Gear titles. When they get to the throne room,they are attacked by Mecha Wario AND Mecha Waluigi. 

Mario and Co. fight the Wa's and Mario returns them to normal with his De-Robot Buster. Wario and Waluigi want revenge and agree to join Mario and Co. on their quest to defeat Bowser and Dr. Eggman.  Their next stop is Donkey Kong Island,where they fight Jungle Animal Badniks,while Mecha Donkey Kong is beating up the other Kongs - including Diddy. 

Mario saves Diddy Kong and battles Mecha Donkey Kong. Mario eventually returns the Ape to normal. Donkey apologies to Diddy and the other Kongs and wants to make Dr. Eggman pay. Diddy wants to help.

Meanwhile,back on Sonic's World,outside Station Square,Kursed Rouge and Kursed Shadow have found Sonic and Co. and are attacking. Kursed Rouge steals Sonic's Silver Ring. Kursed Shadow uses Chaos Control to defeat the heroes. They are saved by Omega,who's been searching for Shadow and Rouge and senses that something is wrong. He decides to "snap them out of it" by attacking them violently with his blasters,despite Sonic's objections. Amy notices that Rouge has dropped the Ring and retrieves it. She uses it to free Rogue and Shadow.

The Reunion is short lived as Bowser Jr. appears in his Jr. Clown Car and kidnaps Amy. He tells Sonic to come to The Starlight Zone alone if he wants to see her alive again. Sonic tells his friends to chill here and that he'll save Amy. Tails wishes Sonic luck. As Sonic is rushing off to save Amy,Mario has just De-Robotisized Toadette in New Donk City.

Toadette,formally Mecha Toadette,thanks Mario for saving her. Suddenly a small robot appears and projects Dr. Eggman. Dr. Eggman congratulates Mario on his progress and tells him that He still has his Princess and that if he wants her,he can come to the Koopa Kingdom and get her. AND,because he's such a "Good Egg",he's provided some Transportation.

Suddenly,a flying battleship,bearing a resemblance to the Wing Fortress,appears,but it's designed with materials from the Koopa Kingdom. Mario decides to go this one alone and tells everyone to rest up here. Luigi wishes Mario luck as Mario boards the ship. 

Meanwhile,Sonic has arrived at the Starlight Zone,where Bowser Jr. is waiting,outside his Clown Car and - tapping his foot and wagging his finger. Sonic has got a heavy case of Dejavu. Bowser Jr. tells Sonic if he's been waiting for him (and calls him a slow-bo,which the hedgehog resents). He then tells Sonic if he can beat him in a race,he'll get the "Cutie". Sonic confidently accepts. 

Kamek arrives and casts a "speed spell" on Bowser.Jr.,making him as fast as Sonic. The race begins and Bowser Jr. uses underhanded tactics from the get-go. Kamek also sticks around,firing lasers at Sonic as he runs. It's a tough race,but Sonic eventually wins and saves Amy. They see an air ship flying above them,with Bowser Jr. and Kamek boarding it. Sonic quickly stows away on the ship. Amy wishes Sonic luck.

Bowser and Eggman are both frustrated and ready the For the heroes. Mario arrives at Bowser's Castle,while Sonic arrives at Dr. Eggman's HQ after dropping from the air ship. Mario fights through Bowser's Castle against various Badniks. Mario eventually makes it to a familiar bridge over lava,where he meets Mecha Peach and Dr. Eggman in his Eggmobile. Mecha Peach tries to kill Mario..all under Eggman's watch.

The battle is tough,thanks to the upgrades Eggman has given her,but Mario eventually De-Robotisizes her. Eggman curses and attacks Mario,but the Plumber defeats him by destroying the Eggmobile using 8 strong stomps. Not to be humiliated by a measily plumber,Dr. Eggman pushes the Switch at the end of the bridge,which causes it to collapse. Thankfully,Mario,with Peach in his arms,long jumps to the other side of the bridge. Dr. Eggman is angry now.

Metal Sonic arrives and escapes with Dr. Eggman,with the evil scientist promising Doom for both Mario and Sonic soon. Mario and Peach have a small,but happy,reunion. Peach decides to join Mario's efforts to stop Dr. Eggman. Meanwhile,Sonic has infiltrated Eggman's HQ and is confronted by an army of Mario Enemies. Sonic takes care of them and moves ahead. He then is attacked by a Giant Porcupo,who emulates Sonic's moves perfectly. Once the Giant Porcupo is taken care of,Sonic races to the Main Room of the HQ and finds it deserted. He runs into Kamek,who tells him that,Bowser is waiting for him on the roof.

Sonic speeds up to the Roof,where he faces off against Bowser in his Koopa Clown Car. Sonic proves ineffective against the Clown Car and Bowser himself. Bowser starts throwing down the Mecha Koopa's,Sonic gets an idea. He stuns the "Cheep Badnik Wannabe's" and throws them back at the Koopa King,hurting him. Sonic does this 15x before Bowser has had enough. The Koopa King is Reall pissed and is ready to Finish Sonic in a 1-on-1 beat-down.

Before he could get out of his clown car,Bowser gets a communication from Dr. Eggman delivered by Kamek. Dr. Eggman declares Phase 2 of the Plan a failure and suggests a retreat back to the Death Koopegg. Bowser refuses,but is convinced by Kamek to do so. Bowser Jr. soon joins his Father. Bowser promises to make Sonic feel his wrath soon. The trio fly away. Sonic has a hunch where the Koopa Clan is escaping too.  

Back at the Koopa Egg Zone,Bowser and Co. arrive back at the Death Koopegg,where Dr. Eggman is waiting. Bower is furious and wants to "barbecue that Hedgehog". Dr. Eggman tells Bowser to calm down and that they'll have their revenge soon,as they still have the Death Koopegg,the Power of the Chaos Emeralds,And that he's currently working on a Death Vehicle that will destroy Both heroes. Bowser tells Dr. Eggman to get to work and that his Minions will keep the good guys occupied.      

They then agree to create that huge Warp Ring that bridges their Worlds After Sonic and Mario are dealt with,unaware of each others True intentions (both bowser and eggman want to rule both worlds,with eggman working for bowser and bowser being robotisized as eggman's 3rd.).

Back at the Mushroom Kingdom,Mario and friends have gathered. Toadsworth is relieved that Princess Peach is alright. Suddenly,Rosalina appears and tells the Mario Team that She sensed that the Universe will be in great peril soon and that King Bowser Koopa and the one called Dr. Eggman will be the cause.

Using her senses,she pinpoints the location of the Koopa Egg Zone,just southwest of the Galaxy and that she will warp them all there. Toadette decides to stay behind and look after things. Rosalina creates a portal to the Zone and the Mario Team enter it. The moment they arrive,they meet up with Sonic's team,who arrived through the Gold Warp Pipe outside of Station Square.

As the Heroes make there way towards the Death Koopegg,Bowser,though a loud speaker,welcomes the Heroes for making it this far,but tells them that this as as far as they go,because they won't survive the onslaught of the Koopa Troop. Suddenly,being led by every Hammer Brother variant imaginable,is Every Single Boss and Sub-Boss from the Mainline Mario Games. 

It's a battle royale between Team Mario and Sonic and The Koopa Troop. Things go well for the Heroes at first,until the numbers game starts kicking in.  Suddenly,another portal opens - It's Prof. E. Gadd,now equipped with a Portal Maker called - The Super Portal Maker 1.0. Prof. Gadd isn't alone,Toadette and Cream (with cheese) are with them - And they brought a treasure chest full of Power-Ups from Both Worlds. 

With the exceptions of Wario and Waluigi,who claim they don't need power-ups,each Hero takes at least 2 power-ups. Mario and Sonic both take a Fire Flower and a Shield Item. They also take a Super Leaf,they'll need them to reach the Death Koopegg. Peach takes the Water Shield and a Power Turnip (which allows the user to throw vegetables). Amy Rose takes the Hammer Bros. Suit (which she finds cute) and the Super Bell (which she picks after peach describes it's powers).

Luigi takes a Lightning Shield and the Pultergust. Tails takes a Shield and Flood (he found it interesting when E.Gadd told him about it). Daisy takes the Fire Flower and Fire Shield. Knuckles takes a Fire Shield and a Super Mushroom. Donkey Kong and Diddy Kong take a Fire Flower and a Boomerang Flower respectively. Charmy takes a Tanooki Suit (which he thought was neat). Vector takes a Rock Mushroom. Espio takes a Double Cherry.  Shadow and Rouge each take a Shield and a Fire and Ice Flower respectively. Rosalina equips a Shield. Yoshi gets a surplus of throwable Eggs.

The Heroes equip their Power-Ups and get back into the battle,where they fare better. Mario and Sonic inform everyone that they'll be going after the "Big Bads". Mario and Sonic equip the Super Leaf,which makes them lose the Fire Flower powers,but they still have The Shield. Sonic calls the Raccoon powers weird,but Mario tells him that kit's the best way to get to the "Nasties in that Flying Egg".

After getting a running start,Mario and Sonic fly toward the Death Koopegg. Bowser is furious and tells Dr. Eggman,who's still working on his Battle Machine,that Mario and "That Pesky Hedgehog" are on their way and asks when this "Machine" will be ready? Eggman tells Bowser to have patience and that it won't be ready for a bit. He tells Bowser to activate the Base's Offensive and Defensive Programs. Dr. Eggman can't wait to turn Bowser into his "mindless" Super Badnik General.

Bowser activates the Bases Defenses and Offenses and says that when Eggman becomes his slave,he'll have him build "Hundreds of Death Koopegg's". Mario and Sonic board the Death Koopegg and make there way inside. Inside the Egg-shaped Fortress is an amalgamation of Koopa Traps and Eggman Traps. The various Minor Enemies are a mix between Bowsers Koopa Troop and Dr. Eggman's Badniks.

Mario and Sonic rush through the Fortress,defeating the Minor Enemies and getting by the Traps,helping each other along the way. They reach an empty room with a shutter. Sonic figures that they hope they're getting close. Before they could do anything,Mecha Sonic,Silver Sonic,and RoboSonic (which I call the sonic robot from sonic 2) ambush them.

The Duo of Heroes are ready to fight. However,Kamek arrives and casts a "Shrinking Spell" on Mario and Sonic. Kamek tells the "Annoying Heroes" to "Have Fun" and leaves laughing evily. Rosalina,sensing the Heroes in trouble leaves the Battlefield for The Death Koopegg. Back inside,the Micro-Heroes are having issues,due to their 3 opponents being bigger than them. Rosalina appears and beats the 3 Robotic Hedgehogs back. She restores Sonic and Mario to normal and tell them that she'll handle these 3 "troublemakers",while they stop Bowser and Dr. Eggman.

Sonic and Mario thank Rosalina and wish her luck. THe Duo press on until they come upon a Door with the Koopa/Eggman Logo on it. Sonic comments on how stupid it looks. Mario believes that they are close now. Suddenly,Bowser Jr. (in his Jr. Clown Car) and Metal Sonic bust in. Bowser Jr. tells the Heroes that Dad and "Dr. Eggy" are busy,but They'll be happy to "play with them".

Mario and Sonic battle Metal Sonic and Bowser Jr. Rosalina is fighting the Trio of Robotic Hedgehog. And the others are fighting and beating the Koopa Troop. Rosalina manages to destroy the Trio and starts to sense an unusual power within this Base and leaves to check it out. Meanwhile,it's a tough fight,but Mario and Sonic defeat their Enemies #2 guys. Unfortunately,Kamek appears once again and uses his Magic turn Metal Sonic into a Ridable Mech Armor for Bowser Jr.

The combined strength of Bowser Jr. and Metal Sonic are too much for the tired heroes,but thanks to some clever and resourceful team work,they manage to defeat the combined menace. After defeat,Metal Sonic transforms back to normal. The Heroes enter the door and are attacked by The Rokoopnik,a massive Battle Machine piloted by both Dr. Eggman and Bowser. The Rokoopnik is a blend of Koopa and the Death Egg Robot.

The exausted Heroes are soundly defeated and captured by the Bowser and Eggman. As the villains are gloating,Sonic interups them by attempting to cause desention between them. It doesn't work. He then asks Eggman why he called Bowser back? Sonic thinks that Dr. Eggman is jealous that the Koopa King was gonna defeat Sonic,something that Dr. Eggman has always failed to do. Mario throws fire to the feul by doubting Bowser can even Beat Sonic in a 1-on-1 fight and thinks that Eggman knew this and was just protecting the Koopa King.

This pisses of Bowser off,but before he could act,a loud alarm goes off and a computerized voice announces that an intruder has infiltrated the Generator Room - where the Chaos Emeralds are. Bowser and Eggman order Kamek,Orbot,and,Cubot take care of the intruder. 

In the Generator Room,Rosalina is inspecting the Chaos Emeralds and is impressed by their beauty and power. She also deduces that the Emeralds are what's giving this "Horrible,Evil Base" it power. Kamek,Cubot,and Orbot arrive and warn Rosalina to back away from the Emeralds or face the wrath of the Koopa-Eggman Team.  Rosalina easily dispatches them and removes the 7 Emeralds from the generator,which causes loud warning alarms and a computerised voice warning that Power has been severed and is suffering a malfunction.

Without the Emeralds the entire Death Koopegg starts to malfunction and lose power. Rosalina leaves to find Mario and Sonic. Bowser and Eggman are livid by the revelation that someone has taken the Chaos Emeralds. Knowing that,without the Emeralds,their base is gonna crash,the 2 prepare to escape in the Rokoopnik,with the intent on leaving the trapped Heroes behind to die with the base. Dr. Eggman promises to reclaim the Emeralds from who ever stole them and make them suffer.

Rosalina arrives with the Emeralds. Bowser is angry that Rosalina has interfered with him again. When asked by Eggman,Boweser explains that Rosalina is the Guardian of the Cosmos in his Universe and one who's helped Mario disrupt his plans on a few occasions. 

Sonic tells Rosalina to throw the Emeralds to him and Mario. Rosalina, knowing that the Emeralds and their great power will be in in good hands with Mario and Sonic,agrees.

Just as the Rokoopnik is about to attack Rosalina,she throws the Chaos Emeralds to Sonic and Mario - turning Sonic into Super Sonic and Mario into Super Mario. The Heroes are freed,fully restored, and are ready to attack. Dr. Eggman wants to make a reteat,but Bowser wants to stay and fight,but is convinced by Eggman to make the escape. The Villian Duo escape in their Rokoopnik,promising revenge. Super Mario and Super Sonic thank Rosalina and chase after their enemies. Rosalina wishes them luck. 

Outside,the battle is over and the Good Guys are triumphant. They watch as the Death Koopegg crash and burn. Amy and Peach hope Mario,Sonic,and Rosalina escaped. As the Rokoopnik is traveling in space,Dr. Eggman and Bowser are blaming Bowser for the destruction of the Death Koopegg and lack of security for the Chaos Emeralds. In his anger,Bowser blerts out his true intentions to make Dr. Eggman his cheif Scientistwhen he takees controll of Both Worlds. This causes Dr. Eggman to reveal His true intentions (to take Both Worlds,Robotisize Bowser and make him his 3rd in command)   

As the 2 are fighting to gain full control of the Rokoopnik,Super Sonic and Super Mario have caught up with them. The 2 decide to settle things after Mario and Sonic are delt with.  And so the Final Battle in space begins,with both sides having no advantage over the other. That changes when Super Mario finds a weak point on the back of the Big Mecha's head.

The Super Duo strike that point 20 times,before the Rokoopnik starts exploding. The Villain's loose control of the Rokoopnik and it comes crashing down on a near by Planet. Before it does though,Kamek suddenly appears and teleports Dr. Eggman and Bowser to safety.

Super Mario and Super Sonic high five each other. A few minutes later,Bowser and Dr. Eggman (with metal sonic,bowser jr.,kamek,cubot,and orbot) are surveying the wreckage that Was the Rokoopnik. Angry at eachother,the 2 begin fighting. Kamek,Metal Sonic,Orbot,Cubot,and Bowser Jr. watch in embarrasment.

Hours later,Back in the Mushroom Kingdom,Mario and Sonic are with their friends near the Gold Pipe that leads back to Green Hill Zone. Both Heroes are back to their Normal Forms. Sonic,Knuckles,Amy,and Tails are carrying the Chaos Emeralds. 

The Heroes talk about their latest adventure. Sonic then tells Mario that it's been cool hanging with Him and wishes they met on better terms. He then tells the plumber that they make a really great team. Mario agrees and promises Sonic that they will meet again one day. The 2 clasp hands. Sonic reveals that The Chaos Emeralds will be "Set Free" back into the Special Zones once he and his friends return to his World. 

The Heroes say their good-byes and promise to meet again someday. Sonic and Friends return to their World via the Gold Warp Pipe. The Warp Pipe disappears. 

The End.
