Cheese, Spongebob, Patrick, Sandy, and Squidward all walked on the hill leading to the Bikini Bottom. The night blue sky seemed dirty orange, the once beautiful flowers that were once colorful were now dark grey and black. Towns were destroyed, most fish were wearing black metal bucket with silver horns on top and 'CM' engraved on each one. Each fish also had on black armor with neon purple fire streaks on each one.

Sandy stared at the appearances in fear.

"Wow, and to imagine he's only doing this to get revenge."

"Tch, for a very stupid reason." Squidward grunted. Spongebob, Patrick, Cheese and Sandy nodded their heads in agreement.

"Well no matter what happens or what happened here today, just know that we're always gonna be in this together alright?" Cheese assured his friends as they nodded their heads in agreement. They turned back to what they had to go against.

Then, they all ran up to the huge crowd of armored fish. Cheese hit a backflip, karate kicking two armored fish with spears backwards. Sandy grabbed Spongebob, spinning in a circle as he punched all the groups of fish out of the way. Patrick drunk two huge bottles of purple fuchsia pop, and held his stomach as he belched, causing the whole army of fish to fall back. Squidward took a golf club, elegantly smacking the fish out of the way. Everyone continued to fight until their path was cleared.

"We...did it." Spongebob replied, saying half-way out of breath.

But their victory had ended, when another army of fish appeared right behind this, prepared to fight. The gang sighed. Cheese pulled them all together in a group huddle.

"Okay how about this, Patrick, you and Squidward take these guys head on and me Spongebob and Sandy will head towards Plankton's tower."

Squidward grumbled. "But it's two against........well 100! We won't be able to beat them if it's just us."

"WHO SAID THAT YOU GUYS GET TO HAVE ALL THE FUN?!"

Everyone turned around and stared in awe. Pinkie Pie, Rainbow Dash, Rarity, Fluttershy, Applejack and Discord all we're walking in a gang. They were all wearing golden armor, caring and holding cannons along with boom guns. Pinkie met up with the huddled gang and smiled.

"This isn't just your fight Cheese," she said, while reaching out for his hand, holding it in hers. "It's our fight!"

Cheese blushed, and grinned at his friend competitively.

"Sorry to ruin the moment here but umm, we have an army of fish to defeat and I don't wanna stay in this world forever." Rainbow interrupted. The party duo turned to the army, as they charged. The duo grinned.

"Alright, Dash, AJ, Rarity, Squidward and Patrick you guys take care of this crowd. Me, Cheese, Flutters, Spongebob, Sandy and Discord will head towards the tower."

Everyone nodded at Pinkie, as they followed her orders. Everyone boosted up their armor, and got to work. Dash and Aj hit power kicks on every opponent that came their way. Rarity and Squidward used the boom guns, and shot forcefully at each fish. They complimented each other on their elegance and posture. Patrick on the other hand, filled up all the cannons with rotted spinach, shooting it directly in the fish's mouth. They all cowered away, whipping off the access spinach from their mouths.

Meanwhile, Pinkie and her crew fought and made it to Plankton's tower. Discord used her party cannon, turning it into chaos cannon, and busted the door down. Plankton and Karen along with more fish armies stared at their unwanted guests angrily.

"Surprisingly, you've made it this far. But you won't be going any further! Minions, ATTACK!" and with that, the armies all charged for the gang. Fluttershy hide behind Discord, who slid on black shades, and shot his cannon at the group of fish heading towards his friend.

Sandy stared at him in confusion. "This is no time for shades ya' know!"

"Yeah but I at least gotta be the cool one here while the princesses are still in the other world." Discord replied, shooting more groups of fish. He turned back to Sandy, with his eyes grown wide.

"LOOK OUT!" Sandy turned quickly, seeing a huge pale of chum being dumped down on her. Spongebob karate chopped the fish he was fighting, and ran towards her quickly.

"SANDY!" he yelled, jumping in the chum. He dug through it, hoping to find a trace of her. He was relieved when he had found her hand reaching out for air. He quickly swam towards her hand before she sunk in, pulling her up to his chest. When he rose her up, her whole helmet inside was covered with chum. Spongebob thought quickly to remove it off of her head, dumping access chum.

Sandy opened her eyes wide, with her cheeks puffed. Spongebob giggled.

"You should be more careful next tim-" before he could finish, the squirrel's lips were already on his. His eyes widened, then he gently closed them, embracing Sandy back. They pulled away from each other, looking into each other's eyes, then Sandy reached out for her helmet.

Spongebob chuckled and handed it to her. When she put it back on, she took a deep breath.

"I was only doing that to get some air to kiss you. Didn't think you'd kiss me back." Spongebob sunk down and blushed.

"Guess I got a little carried away, heh."

Pinkie and Cheese were side by side, fighting off other fish as they came their way. Nothing could stop these two, they were powerful, they were strong, they were one.

Suddenly, Cheese spotted a shadow behind Plankton's throne.

"Sombra?" he asked himself.

He grew suspicious, as he left Pinkie's side, following the shadow. When he reached behind the throne he grew confused.

Until it happened. A speck of the shadow got into his veins, causing him to scream in pain. Pinkie turned quickly, seeing Cheese limp from behind the throne, holding his arm.

"CHEESE!" Pinkie exclaimed, running to his side.

She finally met up with him, reach out from a comforting hug. "Are you oka-" but she was coldly swatted away.

Cheese lifted his head up, with red glowing in his once green pupils. Pinkie stared at him in horror. For this was not the same Cheese Sandwich she knew and loved, no. This was a monster.

Twilight paced across the floor of the Crystal Empire. She began sweating instantly.

"Oh I hope their okay! Was it a mistake sending them? And all those weapons! I mean what else could possible go wrong?!"

Suddenly, the castle began shaking, and Sombra appeared in the throne room with an evil grin towards Twilight.

"Sorry I asked." she said to herself, blushing embarrassingly.

"It's time to take out the young ensemble in the group! You're mine Twilight Sparkle!" Before Twilight could aim her shot, she was blocked by the guidance of Luna who shot her magic at him. Sombra scooted away, running towards Twilight for another try. This time, Shining Armor blocked him with a shield, while Cadence shot.

She gave him a dirty glare.

"So, you made me left my husband for a jerk, eh? Well if you thought Luna could break your heart, just imagine what I'd do to you!" with that, she shot a bomb spell on Sombra, causing him to scoot back once again. He became frustrated, seeing all the royals backing up for Twilight like she was a weakling.

Wait. That gave Sombra an idea. He slowly grinned, laughing evilly as everypony became confused.

"Soo...the young royal is just gonna sit there and let the big ponies fight her fight. What a shame, and here I am thinking we'd be able to fight for real this time. You know, since the little dragon and Princess Cadence here saved the empire and not you."

Twilight's face changed, she became furious.

"I'll kill you, I'll kill you!" she began to protest.

"Now Twilight Sparkle, don't let Sombra get the best-" but before Luna could finish, Twilight flew in the air, aiming at Sombra.

Her eyes became white, with magenta aura flowing behind them. "I'LL KILL YOU IF IT'S THE LAST THING I DO!"

Sombra grinned, while showing his teeth. "FINALLY, NOW THAT'S WHAT I'M TALKING ABOUT!" dodged one of Twilight's spells, but she didn't give up. She kept shooting at him.

He laughing menacingly. "You've REALLY GOTTA WORK ON YOUR AIM MISS SPARKLE!" But Twilight kept shooting. The royals were surprised. Hearing the words, 'I'll kill you' from Twilight was all but expecting. Shining however cheered for his sister.

"Yeah Twily! Kick his shadow butt!" Cadence nudged him on the elbow.

"Ow!" he exclaimed.

Twilight took a deep breath, and began to pressure her final attack on Sombra. But as she shot her beam, he shot his. The two beams met, pushing each other down. Twilight put a little force on hers, which made Sombra's beam weaker, causing him to feel weak in his legs.

Luna's eyes became shot dead with fear. "TWILIGHT! STOP THIS ISN'T THE WAY!"

Twilight opened her eyes, looking down at Luna with sympathy and tenderness. Before she could fly down, Sombra's beam reached up to her, hitting her dead in the face. Twilight fell to the ground selflessly, not moving a single muscle. The royals all stared at Twilight, rushing down to her health. Cadence and Celestia cried, and Shining Armor growled in anger.

Luna arose, staring at Sombra deadly. "This is the end of the line Sombra, there's no more turning back. No more tears, no more regrets. I won't even feel bad for what I'm about to do."

Luna's form changed. Her navy blue coat was now jet black. The pupils in her eyes became skinnier. She grew taller, her teeth became sharp as shark's. Then a light dove blue colored helmet levitated on her head. Celestia stared at her former sister in awe.

"Luna?" Cadence questioned.

"She's brought her back, for Twilight's sake." Celestia corrected. "Welcome back Nightmare Moon."

Luna turned to her sister and smiled slyly.

"I'll handle this. I'll end this." She turned back to Sombra, staring at him coldly which scared him inside. He never seen this side of Luna before, she seemed so emotionless and cold. He grew his pride back and grinned at her evilly again.

"So, you're gonna defeat me by staring at me Luna? What about what we had, huh? Are you just gonna throw it all away? When you left me and abandoned me?"

Silence. Luna cokced her head to the side. "Save your foolishness for another time in another body."

With that, Luna flew up in the air, as her horn glowed. The beam shot down, as her opponent shrieked in fear. Sombra thought quickly to teleport to the other side of the room before she shot him. Unfortunately, she only shot his eye, leaving a scar.

"I still have a companion of mine Luna! You'll never defeat me!" he gloated, running into the mirror.

Luna sighed, changing back into her normal form. Cadence looked at her reassuringly. Luna returned her smile.

"What's gonna happen now?" Cadence asked.

"The others will have to defeat him." Luna replied. Then she stared at Twilight. "She's just going to have to believe in Pinkie Pie."

Author's Note

PHEW! ANOTHER UPDATE AS PROMISED!

The fight scenes were completely hard to compress, but I got the hang of it now.
FYI, Luna can tell that Sombra has taken over Cheese Sandwich's body.
