Chapter 9: Plankton's Defeat

That night was the night when Plankton's reign begins. Plankton had the Nightmare Potion in his hands, changelings were pounding the bottoms of their spears and others were watching.

"This is going to be good." Trixie said getting some popcorn.

"Finally!" Plankton yelled. "After days for planning this, my reign begins!"

"Plankton, don't drink that potion." Celestia said. "You don't know what you're doing!"

"Silence, Celestia!" Plankton yelled. "Soon, Toonera will be mine!" Plankton looked up at the sky. "When the light of the moon gets to me, I will rule the world!" He was about to open the potion, but he stopped when he heard a voice.

"Drop the potion, Plankton!"

Plankton turned and saw the travelers. "But that's impossible! Chrysalis disposed of you!"

"You're wrong, Plankton!" Mr. Krabs said. "We saved that boy before he dropped dead. Now where is my daughter!"

Plankton pointed to a gray whale wearing a pretty pink dress, a purple amulet, yellow gloves, lipstick, and white boots. And she was inside a cage.

The travelers were shocked of Mr. Krabs daughter.

"That's your daughter?" Rainbow asked.

"It was from her mother's side." Mr. Krabs explained. "But meet the Great and Powerful Pearl!"

"Hi there!" Pearl yelled from above. "It's a pleasure to meet you! And yes. I'm a witch."

Plankton growled. "Seize them!"

Plankton's companions ran to the travelers.

Fluttershy turned to the crusaders. "You three take care of Discord."

The crusaders ran to Discord.

"You don't have to protect me, you know." Discord said taking out three prison keys and giving them to the crusaders. "Free everyone in that prison. Give them back what was theirs." The crusaders nodded and ran to the dungeon. Bloo followed the crusaders.

Jay and Nya were surrounded by changelings.

"You take the ones on your side, I take the ones of mine?" Jay asked.

"I'll take it." Nya said.

Twilight was blasting some changelings to get to Celestia and Luna. One of the changelings was about to hit Twilight from behind, but Kai fought the changeling himself.

"Go!" Kai said.

Twilight flew to Celestia and Luna. "Where's the key?"

"It's on that hook!" Luna said.

Twilight turned and saw a key on a hook. She took the key and started to free Celestia and Luna.

Kai was struggling trying to fight the changeling, but Celestia blasted magic at it. Kai smiled at Celestia and fought the changelings with her.

Rainbow was fighting Gideon and his changeling while Lloyd was telling her what to do. The changeling fell and Gideon fell off of him. Rainbow landed and Lloyd got off her.

"This isn't over." Gideon said.

"But the battle isn't yet." Lloyd replied.

"And that's what you get for beating a soldier." Rainbow said kicking the changeling's head.

Pinkie was fighting Trixie and was winning. Trixie was struggling. She tried to get up, but Pinkie pinned her to the ground.

"Squid Ponies dominate the world, Octocorn." Pinkie said. "Any last words?"

"Just this." Trixie replied weakly. "I hate you." She flopped onto the ground.

Pinkie shrugged and jumped to Jay as she squirted ink at the changelings. Jay smiled and hopped onto Pinkie's back.

Squidward was struggling trying to blow away some changelings. Luckily, Rainbow punched some changelings out of Squidward's way.

"Thanks." Squidward said.

"Anytime, Squidward." Rainbow replied.

Dipper was trying to get away from the battle he was in, but he felt a tap on his shoulder. He turned around and saw a nindroid about to hit him with a spear. Dipper screamed and braced himself as Mabel kicked the nindroid down. He turned and saw a changeling running at him.

"Dipper, behind me!" Mabel said.

Dipper ran behind Mabel and saw her beat the changeling. 'Wow. What a guardian.'

Cole was backing up, but he suddenly found Rarity behind him. An idea popped into his head as Cole grabbed Rarity by the legs and spun around to knock down many changelings. After he knocked many changelings down, Cole puts down Rarity.

"You had you use me as a weapon?" Rarity asked.

"It was the only thing I had in mind." Cole said.

Fluttershy was flying to avoid Sombra's attacks while Kenny was blasting Sombra's tentacles. Kenny grabbed one of Sombra's tentacles which electrocuted Sombra. Fluttershy looked down and saw Zane struggling fighting Starlight. She flew down and caught Zane for safety. Zane threw a shuriken at Starlight freezing her hooves to the ground.

"Curse you!" Starlight yelled.

Applejack and Sandy were knocking down some nindroids. Sandy kicked a nindroid in the head and threw him to a wall. Applejack grabbed a nindroid by the shirt and threw him to Spongebob. Spongebob punched the nindroid to the ground.

Zecora, Skips, and Mr. Krabs were running to Pearl.

"Pearl! Where's the key?" Mr. Krabs asked.

Twilight turned to Mr. Krabs. "Mr. Krabs!" She takes out a key. "Use this!" Twilight throws the key.

Mr. Krabs catches the key and throws it to Pearl. Pearl catches the key and unlocks herself. She jumps out of the cage and lands on the ground with no damage.

Patrick watched the fight with Discord. "This is intense."

All of Plankton's companions fall and the travelers get to Plankton.

Plankton growled. "Dragon!"

A dragon that looked like the one that destroyed the trio's home comes out of the dark.

The travelers were shocked.

"What do we do!?" Pinkie asked.

"We need another." Dipper said.

Twilight turned to Dipper. "Another?"

"Another dragon." Dipper explained. "We need another dragon."

"I know where the dragon room is." Discord said. "Just wait here." Discord flies to someplace else in the castle.

Meanwhile, Bloo and the crusaders were in the dungeon about to free all the prisoners.

Bloo unlocked one of the cells and saw a bunch of talking food. "Go! You're all free!"

The food run out of the cell.

"Yay! I love freedom!" The marshmallow said.

Apple Bloom opened the next cell and saw a red stallion (Big Macintosh) and a yellowish green elderly mare. (Granny Smith) "Granny! Big Mac! You're free to go!"

Granny Smith and Big Mac ran out of the cell.

Back with the travelers, they were waiting for Discord to come back. Discord came back to the travelers.

"What took you so long?" Rainbow asked.

"Everyone." Discord said turning around. "Meet Spike!"

The travelers turned and saw a giant purple dragon come out of the dark all the way to Plankton's dragon.

"He's actually a baby dragon." Discord explained. "I used a spell on him to turn him older. I'll reverse the spell after he's done with Plankton's."

Kai puts on an angered face and turned to Plankton. "You owned that dragon that scarred me for life? It's your dragon's fault that I kept having dreams in the first place!"

"My dragon?" Plankton asked. "Don't you see? I filled your head with dreams. I took away your home. I scarred you for life!"

Kai puts on a shocked face.

Plankton looked up and saw the moon above him. He opens the potion. "Finally, my time has come."

"No!" Celestia exclaimed.

Plankton drank the whole potion and dropped the tube. The moon turned purple and a dark ray went to Plankton. It swirled around Plankton turning him into a monster. The light faded and the travelers saw the state Plankton was in. Plankton was now huge, dark green, had dragon wings, his antennas were now horns, and a dragon's eye. Plankton laughed.

The travelers were shocked.

"We're too late." Nya said.

"No we're not." Celestia replied. "Luna has a secret weapon."

"Speaking of Luna, where is she?" Kai asked.

A hunk of smoke landed in front of the travelers. And what came out was a dark version of Luna.

"Everyone." Celestia added. "Meet Nightmare Moon."

Plankton turned and saw Nightmare Moon. "Well, well, well. Nightmare Moon. I've heard a lot about you. Can't you look at yourself for once? You have the potential to rule Canterlot while I will take the key to my victory. Join me and they will soon learn to fear the night."

The travelers turn to Nightmare Moon.

"Never!" Nightmare Moon yelled. "There can only be one nightmare in this world. And I will never let you take this world or my place!" She blasted a beam of magic at Plankton, but unfortunately, Plankton dodged the beam and flew up into the air. Nightmare Moon did the same.

Back with the crusaders and Bloo, they freed all the prisoners in the dungeon bringing them to the tunnel so they can see the world again.

"Single file!" Bloo said. "Single file when you get into that tunnel. It's the way out of all your miseries."

Apple Bloom was leading all the imprisoned children. "That's it. You're all free to go home. But be careful. The world can be dangerous sometimes."

Sweetie Belle was giving food to the starving prisoners. "Eat up. Chow down. I hope you like apple fritters. Bon appetit."

Scootaloo was freeing the chained prisoners. "You're free to go."

Meanwhile, the travelers were watching Spike winning the fight between Plankton's dragon. Spike won the fight and Plankton's dragon dropped dead. Discord then used a spell to turn Spike back into a baby dragon.

Spike rubbed his head. "What happened?"

Fluttershy hugged Spike. "You're so cute."

Plankton and Nightmare Moon were fighting magic with magic. Nightmare Moon dodged every attack from Plankton. Plankton was trying to get Nightmare Moon to give in, but she didn't give up at all. They both went up to the moon and blasted each other with magic. The two beams were pushing each other, but Plankton's was more stronger due to his strength. Plankton's beam hit Nightmare Moon, which made her turn back into Luna and hit the ground of the castle.

"Luna!" Celestia yelled.

Plankton went back into the castle and stood on his throne. "Celestia, you're no match for me. Neither is your sister. The king of the Mainland will die as soon as I get there. I've seen who the Elements of Harmony are. But I don't see their symbols. Which means they're just a bunch of ponies. Those ponies don't even stand a chance against me. Not even their friends can stop me."

Twilight puts a brave face on and walks up to Plankton. "You're right, Plankton. We are just ponies."

Plankton chuckled. "Of course I am-"

"We've traveled for days to get here to you, Plankton." Twilight continued. "I had faith the first time my friends and I went into the world to save the balance from you." Twilight points to the medallion. "But thanks to Celestia and Luna for giving us this medallion, we have all the answers to stop you."

"Well, the medallion is the most intelligent to get the answers to save our home." Celestia said.

"And thanks to Celestia and Luna, we will stop you with our friendship." Twilight finished.

The magenta jewel on the medallion glowed.

Pinkie walked to Plankton. "Yeah. And we will stop you and your meanie companions from stopping us."

Then the blue gem glowed as Plankton noticed the medallion.

"We can save our home from you, and we will!" Rainbow yelled.

The red gem glowed.

"I hate to be a judge of your appearance, Plankton." Rarity said. "But you're ugly."

The purple gem started glowing.

"You have been a bad man." Fluttershy added. "And you should be on a Time Out."

The pink jewel started glowing.

Applejack joined the other elements. "We might be ponies, but we have the Elements of Harmony in our souls."

And the orange jewel glowed.

Plankton wore a face of fear. "What are you doing?"

"Believe us, Plankton." Twilight said. "But if we showed you the most important things in life,"

The medallion floated off Twilight's neck and started to glow.

"It will be Honesty." Applejack said as an orange beam from the medallion swirled around Applejack.

"Laughter." Pinkie said. A pink beam flew to Pinkie.

"Loyalty." Rainbow said with a blue beam surrounding her.

"Kindness." Fluttershy said as a yellow beam flew around her.

"Generosity." Rarity said. A white beam went around her.

"And finally, Magic." Twilight said looking up at the medallion seeing a purple beam fall down to her.

"What's going on?" Plankton asked in a tone of fear.

"Put those together and we have," Twilight said.

The medallion splits up and goes to the chosen elements. The colorful lights faded and showed the elements wearing armor with the gems of the medallion sculpted into the shapes of their Cutie Marks.

"The Magic of Friendship." Twilight said.

Plankton became more fearful seeing two ribbons with the colors of the rainbow fly above the Elements of Harmony. One red, orange, and yellow. And the other, green, blue, and purple. The two ribbons merged as a rainbow flew to Plankton and surrounded him. Many colors flew to Plankton's companions turning them into stone. The colored lights didn't turn Starlight, Trixie, and Gideon into stone, but sent them to the moon. The colored lights unchained Discord giving back his freedom.

"I am free once again!" Discord exclaimed.

Then the colored lights healed Luna. The rainbow shined brighter and made an explosion of light turning the moon back to the right color. The light faded and the rest saw the elements float down to the ground. The gems glow and the armor turned back into a medallion.

Kai ran to Twilight and gave her a big hug. Twilight hugged Kai back.

The travelers turned and saw Plankton back to his regular state. Celestia walked up to Plankton.

Plankton looked up at Celestia with a face of sadness. "I'm sorry. I just wanted to be noticed."

"I know." Celestia said. "But promise not to do that again."

Plankton nodded. Celestia picked up Plankton and puts him on her head.

"So, what now?" Nya asked.

"It's about time you all meet the king of the Mainland." Luna said.

"Don't worry." Rarity added. "I've met the king the first time I given back his crown from a thief. But I would love to see the king again."
