Chapter 12: The Final Battle

After a short walk, the heroes and villains came to a huge room, a combination of a throne room and an arena, where, sitting upon two thrones were Ultimecia and Sheva, who watched their enemies arrive.

"I cannot believe you made it all the way this far. Do you fools seriously think you can defeat us? Us, the Mistresses of all Evil?" Ultimecia questioned in her usual overconfident self.

"You guys must be even bigger fools than we thought." Sheva added.

"Ultimecia and Sheva, apparently you two have been rather busy since we last saw each other." Rosalina scowled as she crosses her arms.

"Busy on trying to see you again, baby sister!" Ultimecia said, floating down alongside Sheva, where they glared at the blonde.

"You were always loved by our parents, which filled our hatred for you! We tried to destroy you and our parents banished us here!" She yelled, again blaming Rosalina for their actions, before explaining. "The subversive reversive radioactive conditions here sharpened our skills and deformed our child-based minds! Just like ingredients for the classic recipe in the Evil Villain Cookbook."

"You see, sister, when it comes to evil scientific prowess, we learned from the best, like Bowser, Wart, Cackletta and all the other villains of your perfect little world." Sheva added.

"So you did all of this, just to exact revenge on me?" Rosalina questioned. "But why involve Mario, my friends and Bowser?"

"The best way of revenge is to start by weakening your enemy. And the best way was by destroying your beloved friends." Ultimecia replied.

"Well, I do appreciate you taking some evil ideas from me..." Bowser admitted, feeling it like a compliment, only for his mood to change.

"But playtime is over!" He yelled as he held up a giant cage.

"Time for you two to get locked up!" The Koopa King stated, throwing the cage, which trapped the sisters inside, surprising them as they were locked up.

"Hahaha. I sometimes capture Peach that way." Bowser mocked.

"Hmph! That is what you think, Koopa Brains." Sheva said back, while Ultimecia glared at the group.

"That's it, Rosalina! You and your friends wanna make up for the lost time and play with your sisters? So be it!" Ultimecia snarled, showing their power as the cage begin to shake as dark magic consumed it, causing huge robotic legs to sprout out, shocking Bowser and the others as the cage was then covered by a metal robotic body, before two cannons emerged from the top and a set of claws emerged from the sides of the machine.

"A giant robot? That doesn't make sense." Hal stated.

"What'd you expect? I'm a talking mushroom and you're a turtle standing on two feet. None of this make sense." Jeff replied, facing the machine, while Bowser and Bowser Jr just froze in place, making Rosalina sigh in disbelief that the mighty Koopa King was intimidated.

But coming so far, Rosalina stepped forward.

"Mario, Yoshi, everyone, this is my battle. Let me handle this." Rosalina said, making the others nod in understanding.

"Alright, just but be careful." Yoshi replied, not wanting Rosalina to lose.

"And if things get worse, which they normally do when facing a giant mech, I have an idea." Mario added.

"Think you guys can hold them off when we return?" He asked, which made Rosalina nod, before he jumped on Yoshi's back and began to run off.

With Mario and Yoshi leaving and the Koopa duo scared in place, the robot started to move towards them.

But Kylie, Hal, Jeff and Rosalina all remained determined to stop the machine and Rosalina's sisters from their evil, just as six towers, each with a generator, rose from the floor and around the arena.

"You three! Those generators are giving the robot power. So if we destroy these..." Rosalina began to say, giving Kylie the idea and making her finish Rosalina's thoughts.

"Then we shut off the power supply. Got it." Kylie called back, just before dodging a black coloured Fireballs with red eyes, before she rushed over to one of the towers, used her climbing gear to reach the top and smashed the generator, followed by leaping up, tucking into her shell and smashing the other generator, bringing the power of the mech down to 75%, while Hal, following Kylie's way, climbed up to a set of generators and destroyed them.

Now the machine was only receiving 50% of its power.

As for Rosalina, with the help and trust of her Lumas, they had joined the fight, assisting the one they loved like a mother and helped Rosalina get to the top, to which they grabbed each other's hands, wrapped around Rosalina's and acted like a whip, wrapping around the generator at the top and pulling the blonde up, where she used her sister's rage to her advantage, making them slash at her, but missed, destroying the last two generators and cutting the energy to 0.

As soon as the pillars and generators sunk back into the ground, the robot went back to the centre, where its hands retracted, showing it wasn't out of tricks, for it then withdrew two mighty looking blasters from its being.

"You've gotta be kidding me!" Jeff said, annoyed.

Seeing the weapons, Rosalina snarled as she prepares to fight again, but stopped when Bowser and Bowser Jr stepped in front of her.

"We got this one covered." Bowser said, before he face the mech and called out. "I realised something. I'm the King of Koopas. I don't get imitated, I intimidate!"

"You tell her dad!" Bowser Jr said in a proud reply as he got on his father's back, making the father and son look at each other and smile.

"Bowser..." Rosalina said, amazed.

"Save the thanks for later." Bowser interrupted. "Right now, we have a machine to scarp."

With that, the robot then fired, unleashing several blasts of dark energy from the right cannon, which Bowser dodged, before countering, as he and Bowser Jr began to spit out several fireballs at the cannon, weakening it.

And continuing to show they were the tops when it came to villainy, Bowser Jr called upon his Koopa Clown Car, got in it and took flight, where he hovered over the battlefield and began firing cannonballs from the vehicle's mouth.

Focusing on the aerial target, the robot charged up it's laser cannon, firing a huge blast of negative energy at Bowser Jr, who used his aviation skills and dodged the blast, making Bowser smile, proud of his son.

"Papa, catch!" Bowser Jr then called out, finding something he thought would prove useful within his vehicle, to which he then threw a Mega Mushroom to Bowser, who caught and ate it, making him grow in size and laugh.

"Thanks, son." Bowser said, grateful for his boy's assistance, before he let out a giant ball of flame, destroying the left cannon, while dodging the laser cannon blasts.

Bowser then charged at the robot and grabbed it's body, trying to rip the second cannon off, but the robot countered as it fired, striking Bowser's chest and making him shrink back to his normal size as he crashed to the ground.

"Dad!" Bower Jr called out in concern, making Hal add, showing his worry for his King. "Get up, boss!"

Refusing to let a little dark energy keep him down, Bowser rose up, roared and fired a final blast of fire at the laser cannon, completely destroying it, which made the Koopa King smirk and chuckle.

"Now we've got you!" He stated, before he charged at the mech, but the robot summoned three barriers around itself, which Bowser ran right into, before he was struck back by the mech's next weapon, a blade made of dark energy.

"A barrier?" Kylie asked in shock.

"Now what?" Hal asked, unsure how they could stop it without Bowser.

The robot turned to aim at Rosalina and brought the sword up.

"Rosalina, look out!" Bowser Jr cried out.

As Rosalina saw the sword brought down on her, something blocked the sword, a huge familiar mech of a plumber saved her from being killed.

"Mecha Mario?" Bowser asked in surprise, while Rosalina looked up to see a familiar red hat plumber piloting the mech.

"Mario!" She called, glad to see he had returned, and with a great weapon at his command.

"Sorry I am late." Mario said as he then turned the mech around.

"You got good control in there, Yoshi." He commented, to which inside the centre of the mech, Yoshi, with wires attached to his arms, belly, forehead and legs, was doing the movements, while Mario has control to Mecha Mario's weapons.

"Thanks. Now let's finish this!" Yoshi said.

"You think controlling that mech would be enough to beat us!?" Ultimecia called from within her robot.

"Well you only have that blade left so it should be almost over for you. Let's go, Yoshi and Mecha Mario!" Mario called out.

Yoshi then moved the mech to avoid the blade strikes by the twins' mech, before Mario took aim and fired several Bullet Bills between the gaps of the barriers hitting the twins' mech.

"How is he using that mech so well?" Hal asked.

"Remember, Mecha Mario is programmed with an electronic brain, programmed with Mario and Yoshi's own cerebral patterns." Bowser reminded everyone as he got to his feet, where he added. "So they are pretty much in sync."

Mecha Mario then dodged from another laser blade, as Yoshi held his belly out to open a chest component and Mario fired the Red Bullet Bills at the sister's mech, damaging both the machine and the sister's egos.

Ultimecia snarled, while Sheva held the control stick to swing the blade down, but Yoshi made Mecha Mario bring his right arm up, grabbing the hilt of the blade and pulled back, tearing it from the mech.

"This is the end, Ultimecia and Sheva. It's game over for you!" Mario called as he fired the last bullet bill at them, hitting them and breaking the barrier, where Mecha Mario jumped in and used it's blade and slice the robot across the chest, making it catch fire and break down.

And with their weapon in ruins, Ultimecia and Sheva flew out of the mech, terrified.

"Let's get out of here!" Ultimecia cried out, not wanting to wind up like their mech, with her sister following in her stead.

"They're getting away!" Yoshi cried out, about to pilot Mecha Mario to pursue them, but stopped when Rosalina gracefully flew up and landed atop Mecha mario's head.

"No. Let me handle them. You guys just find the machine to give our world the goods back and then meet me back at the castle at our world. It's time I settled the score." She told them, before teleporting away.

"Look! Over there! I see it!" Hal called out, pointing to a huge machine, which had a computer screen, showing that the generator stealing all the good from their world, making Kylie rush to the machine, used her computer skills and hacked her way in.

And then, with a single command, the machine reversed its effects, putting things back to the way they were, making Kylie smile and say. "Here's your goodness back, world. Bon appetit."

With that, all the stolen good from their world was slowly returned to the Mushroom Kingdom, saving the whole world from having it goodness stolen from them, another victory for Mario and the others

"Now that we taken care of that, let's return to our lab back to our world. Rosalina will catch up with us soon. Don't forget she is kind of a Goddess" Bowser then said, making everyone nod in agreement with Bowser and headed off, while Rosalina's Lumas looked up, to the dark skies, but knew their mama would be ok.

-Meanwhile, with Sheva and Ultimecia-

The pair had crashed outside Evil Mario's house, where they rose up, angered and humiliated.

"Curse you, Mario! Curse you, curse you, curse you thricefold! So it comes to this we are finally defeated! Painfully! Ignominiously! But particularly painfully." Ultimecia said as she clutched her arms to see a bit of blood splash out.

"But how did we lose? It's simply not possible." Sheva said sadly.

"Those guys have something you two don't have." A voice told them, making both sisters turn around to see Rosalina appear before them.

"The will to not give up."

She then wave her wand around, casting her magic to make her Biker outfit vanish and replaced it with usual dress.

"Give yourself up, my sisters. You have failed. You shall never steal anything from my world ever again!" Rosalina said, giving her sisters a final chance to show some good.

"You! YOU! You ruined everything! But even if we failed, we can still dispose of you, that is what this is all about!" Ultimecia yelled, before she and Sheva took out their wands, the same wands their parents constipated from.

"While you are out babysitting Lumas, we took our wands back from our parents' safe. So now, we can dispose of you and then we exact revenge on your friends and foes afterwards." Sheva told Rosalina.

"If you're planning to use that dark magic against me, it won't work this time, as there is something else that you don't know." Rosalina replied, before all three sisters held their wands in the air.

"Shut up and turn into a chicken!" Ultimecia shouted as she and Sheva fired their magic.

"Mirror Reflect!" Rosalina called out, waving her wand to summon a huge crystal-like mirror in front of her, making Ultimecia and Sheva's spell bounce off it and causing her sisters to scream in agony as their own spells hit them.

And dropping her barrier, Rosalina then stepped forward, approaching each wand and breaking them, before she looked down at her two sisters, now of whom had become chickens.

"If this is the same spell you tried to use on me when I was a baby, then you two are bigger fools than I thought." Rosalina commented.

"You... We'll get you for this, Rosalina!" Ultimecia clucked in rage.

"No. I get the feeling this is the last we see of each other. Goodbye, my nasty sisters. If I see you two again, it'd be a millenia too soon." Rosalina replied, turning to take her leave, but not before one final word.

"Dinner time boys!" The blonde called out, before she disappeared, back to her friends, leaving Ultimecia and Sheva confused on what she meant, that was when two shadows towered over them, making both turn to see Evil Mario and Evil Yoshi looking down on them, with Evil Yoshi licking his lips.

"Oh boy, I love roast chicken." Sheva commented, imagining herself cooked.

"I don't know where you two come from but you both be perfect for our dinner tonight. Yoshi, get plucking," Evil Mario said, making Evil Yoshi nod and approach them, claws drawn.

"Well, for a Mario game, this is one heck of a dark ending." Ultimecia said in defeat, just before Evil Yoshi grabbed them both, leading to loud of screaming, plucking of feathers and gobbling sounds.

It was not a pretty sight so let's leave them to their fates and check up on our heroes.
