Let's get right into it!!!

XX

Bowser and Kamek made it to the roof of the castle, it was enclosed by the Bowser head at the top. Kamek waved his wand and the head disappeared. The stone flat top floor came into light, with the cannon in the middle. They looked up to the portal had grown immensely.

"Gwahahaha!" Bowser laughed evilly.

"Sire! They're coming!" Kamek motioned to the stairs.

"Let them. They'll have front row seats to the show!" Bowser said.

The group all ran up the stairs and saw the massive portal.

"What is that?!" Steven yelled.

"It's the beginning of the end." Bowser said.

"Kamek! Now!" Bowser yelled. Kamek zapped Bowser with his wand.

Bowser was enveloped in a bright white light. The group shielded their eyes. Bowser grew to the height of Petey Piranha, and Moonstones gem embedded itself on his chest. The white light cleared and everyone saw Bowser's new look.

Bowser was a lot bigger. His skin was dark grey, and his belly was white. His shell was dark gray and spiker were white and his eyes were white too. His hair was a lot longer and grey.

"Mama Mia!" Mario and Luigi yelled.

"Gwahahaha! This is the end of the line!" Bowser yelled. Kamek used his broom to fly next to Bowser's head.

"Come! Come my minions!" Bowser yelled, raising his arms.

XX

In the theater of Bowser's Castle. They heard the call.

"Alright! Let's go!" A Goomba yelled. All the minions stood up and began rushing towards the portal. While in the very front, Professor E. Gadd, still disguised as a Koopa Troopa, was pushed through.

XX

"Yes! Yes!" Bowser laughed evilly as his minions began falling out of the portal.

Everyone watched in horror.

"Garnet, it's an invasion!" Pearl yelled.

"We need to close the portal!" Connie yelled.

"But how?" Luigi said.

Mario remembered seeing Bowser turn the cannon on.

"We need to destroy that cannon! It's the reason the portal is open!" Mario yelled.

"I'm on it!" Garnet yelled. She launched her gauntlets at the cannon. They hit the cannon and it fell over and powered off. The portal suddenly closed.

"Huh? What?" Bowser looked down and saw the cannon destroyed. "NO!"

All the minions who landed, about 20 of them, including E. Gadd, looked at their new surroundings. They all saw Bowser and gasped in awe.

"King Bowser, you look great!" A Goomba yelled. A lot of compliments were being thrown at Bowser.

"ENOUGH!" All the minions went silent. "Get them!" He pointed at the group.

"It's the Mario's! Get'em!" A Dry Bones yelled.

The minions all charged at them, except for one Koopa Troopa.

"Hey! You! Attack them!" Bowser yelled down at the Koopa.

"I don't think so, you rotten Koopa!" The koopa said. The koopa suddenly started to fade and turn into Professor E. Gadd.

"The old coot that lives in the woods?! How are you here?!" Kamek yelled down.

"That's not for you to know! And now, I think it's time that I put a stop to this silly invasion." E. Gadd said. He pulled out the wand he took, and shot the minions with a blast. All the minions were sent back to Bowser's castle.

"*gasp* Professor E. Gadd!" Luigi yelled. He ran up to the old man and hugged him. The rest of the group walked up.

Bowser stomped his foot in anger.

"THAT'S IT!" Bowser stepped forward. "I'LL JUST HAVE TO FINISH THIS MYSELF!" He reached into the Moonstone gem and pulled out her hammer.

"Kamek! Take care of the old man!" Bowser ordered.

"Yes, your grouchiness." Kamek flew down to E. Gadd and picked him up and flew him down the castle.

"Professor!" Luigi yelled.

"Don't worry, bro. We'll get him back." Mario said. "But we've got bigger things to worry about!"

"I've been waiting for this moment since we were babies!" Bowser yelled.

Final Boss Fight: Bowser

Bowser swung the massive hammer and the group jumped out of the way.

Bowser inhaled and breathed a white stream of fire at the group.

"Watch out!" Steven yelled. They all ran the other direction. Until the stream of fire started surrounding the group completely. They were all caught in a ring of white fire.

"Ah! I can't die! I still have internet arguments to win!" Peridot yelled.

Bowser walked over to the trapped group. He raised his hammer and swung it down with force. Everyone braced for the impact, but the hammer stopped a few feet before it crushed them. Everyone looked to see Garnet, barely holding the hammer.

"Go! Go!" Garnet yelled, struggle in her voice. Mario and Luigi ran over to the wall of fire and put out a little part with ice balls. Everyone, minus Garnet, ran out.

"Oh no! Garnet!" Steven yelled.

In the ring of fire, Garnet's arms were shaking.

"Give it up already!" He yelled.

"Not...a...CHANCE!" With that last word, she pushed up, and shoved the hammer back into Bowser's face.

"D'ow!" He yelled. He dropped the hammer and held his nose. Garnet ran out of the ring of fire.

Bowser stumbled from the pain in his nose and tripped over the hammer, into the ring of fire he made.

"I bought us some time, we have to come up with a plan!" Garnet yelled.

"There's no time! He's getting back up!" Mario yelled.

"I have an idea!" Lapis yelled.

"What is it?" Peridot asked. Suddenly, Lapis summoned her wings and flew Peridot in the air.

"Woooooah!" Peridot yelled.

Bowser got up and picked the hammer back up and roared.

Garnet took notice to the newly made cracks on Bowser's nose.

Bowser started running to the group.

"Alright, Peridot, ready?" Lapis asked.

"Ready for whaaaAAAAAT?!"Lapis threw Peridot at Bowser's face.

Peridot landed in between his eyes. And it made him halt in his tracks.

"Gah! What is this?!" Bowser yelled as he shook his head aggressively to get Peridot off.

"*gasp* She's distracting him!" Connie yelled.

"You're right! Hurry, before he gets her off!" Luigi yelled.

Connie ran at Bowser, blade raised. Jumped and sliced at his leg, but nothing happened.

Mario and Luigi were hitting Bowser's feet with their hammers.

Pearl was shooting laser blasts and Amethyst was whipping at his legs.

"Get...OFF!" Bowser picked Peridot off and threw her behind him, and off the castle roof.

"Peridot!" Lapis yelled. She quickly flew and caught her before she hit the ground.

"Thanks." Peridot said, blushing a light green.

"Anytime." Lapis said, blushing a dark blue.

Lapis flew them back to the group, who were still attacking the legs of Bowser.

Bowser raised the hammer and hit the ground with it. A white shockwave appeared and knocked everyone back.

Luigi got knocked back on his feet, but on the edge of the castle roof.

"Mama Mia!" Mario yelled. He knocked into Luigi, pushing them both off the castle roof.

Before they fell, Mario grabbed the edge, with Luigi holding onto his feet.

"Mario! Don't let go!" Luigi yelled.

"Lapis, help them!" Connie yelled.

"On it!" She replied.

"No you don't!" Bowser yelled. He jumped in the air and punched Lapis to the ground.

"Lapis!" Peridot yelled.

Lapis was struggling to get up. Bowser's foot raised above her.

"I got you!" Amethyst wrapped her whip around Lapis and pulled her to her.

Bowser walked over to the edge, where Mario and Luigi are dangling.

"Well, well, well, looks like this is the Mario Brothers demise." Bowser chuckled. He inhaled slowly. A bright white glow could be seen forming in the back of his throat.

Mario and Luigi's eyes widened in terror.

"I love you Luigi!" Mario yelled closing his eyes.

"I love you too, brother!" Luigi replied.

Bowser was about to release the fire, when he felt something hard hit his shell and push him forward.

Bowser yelled as he fell, he accidentally threw his hammer behind him. He swiped his hand and hit Mario, causing the plumber to let go. The three tumbled down the cliffside and landed on the beach.

"Mariooooo!" Peach yelled. The group all ran to the edge and watched them fall.

A huge cloud of sand appeared. When it cleared, Bowser had landed on his stomach, he got up and there wasn't a single scratch on his body.

Mario and Luigi landed next to Bowser.

"What?! He isn't even hurt!" Connie yelled.

"Garnet, how do we stop him?!" Pearl yelled.

"I don't know! The only thing that really hurt him was-" Garnet stopped when she saw the hammer laying by the edge. And the cracks that she saw on Bowser's nose. "The hammer."

"What?" Amethyst asked.

"The hammer!" Garnet yelled. "The only thing that can defeat him is Moonstone's hammer! Lapis, Peridot, go down there and keep Bowser in front of the cliff with Mario and Luigi! Everyone else, with me!"

"On it!" Lapis said. She picked Peridot up and flew down to the bros.

Garnet grabbed the hammer and she, Amethyst, Pearl, Steven, Connie, and Peach ran down the spiral staircase.

"Oh no, he's getting back up!" Luigi yelled. He and Mario backed up from Bowser.

"Have a load of this!" Bowser yelled. He swung his fist to the ground the bros were standing on. They jumped out of the way and Bowser's fist hit the sand.

Bowser was going to swing again but a stream of water hit him in the face. He looked up and saw Lapis, with Peridot on her back, flying in the air.

"Why you!" Bowser said as he charged up his fire breath. Lapis raised an arm and the ocean to the left of Bowser started to morph into a giant hand. And it grabbed ahold of Bowser. "W-What is this?!"

Mario and Luigi started throwing ice balls at Bowser's feet, freezing him to the beach. With the giant water hand, and his feet frozen, Bowser was immobilized.

Atop, the cliff, Bowser's Castle started to move a little bit towards the egde. Everyone looked up.

"What?!" Bowser yelled.

XX

"It's working!" Peach yelled, holding the hammer.

Amethyst and Pearl fused into Opal, and Steven and Connie fused into Stevonnie.

Garnet, Opal, and Stevonnie were all pushing the castle.

"Come on guys! Just a little more!" Stevonnie said.

"Alright, everyone, on three, push as hard as you can!" Garnet said. "1...2...3!"

They all pushed and the castle started tumbling down the cliff.

XX

A giant shadow appeared above Bowser.

"Oh no." He said. The castle crashed on top of him and broke into rubble.

Lapis landed next to Mario and Luigi, with Peridot. The rest of the group ran on the Beach, except for Garnet.

They all gathered around the rubble. Until Bowser's hand shot through the rubble. He pulled the rest of his body out, he got on one knee and was panting.

"Did...you really think... it'd be that easy?" He asked catching his breath. "I'm unstoppable!" He yelled.

Garnet was watching him talk from the top of the cliff. She jumped from the cliff, holding the hammer. She raised the hammer and when the timing was perfect, swung it right into the center of Bowser's head. Garnet landed with the group.

Cracks started forming all up and down his body.

"No! Nooooo! It's not possible!" Bowser yelled. "I was so close!" His body exploded in a white light.

Then, laying in the middle of the rubble, was a Moonstone gem and an unconscious Bowser, who was back to his normal form.

"We...did it." Mario said smiling slowly.

"We did it!" Steven yelled.

Everyone started whooping and cheering.

XX

Bowser has been defeated yet again, but one more task remains at hand. And that's going back home.
