Bitter Taste was sitting on the throne in the cloud castle until a cloud came along and started speaking to him in some kind of language.
"Couldn't find her in Canterlot, huh?" said Bitter Taste, "Well, she's gotta be somewhe..."
Suddenly, he has a realization.
"Hang on," Bitter Taste said, "Tell some of the clouds to search Canterlot, Seaward Shoals and the Crystal Empire. If I'm right, Rainbow must have returned the alicorn hood to the original alicorns."
The cloud then took off.
"Ponies, in here immediately!" He yelled out.
The entranced Mane 4, along with Apple Bloom and Sweetie Belle, who were also hypnotized, came into the room.
"Yes, master?" They all said in unison.
"I want you to go down to Ponyville and if you see Rainbow Dash or anyone else, sound the alarm." Bitter Taste ordered.
"Yes, master." The hypnotized ponies said before they left the throne room.
Bitter Taste then laid back on his throne.
"If Rainbow Dash thinks she stands a chance against me, she has another thing coming."
...
"If Bitter Taste thinks he stands a chance against us, he has another thing coming." Rainbow Dash said as she and her friends (except Yona, Silverstream and Smolder) were on the path that led out of the Everfree Forest.
"Well, just stick to the plan, and maybe he won't." Twilight said.
"Right." Rainbow Dash said.
They then came near the entrance to Ponyville and saw some of the cloud guards looking around and even the hypnotized Mane 4 and 2 of the CMC.
Scootaloo gasped before Rainbow Dash comforted her.
"There, there Scootaloo," Rainbow Dash said, "We'll free them soon."
"And we will save the rest of our friends," Twilight said, "Now let's put our plan into action."
Everypony nodded.
...
As the clouds continued to move about Ponyville, one of them was hit with something that froze it in place before plummiting to the ground and hitting it, causing it to shatter. This captured the rest of the clouds attention as they saw Zecora and Sandbar down below, holding a bunch of bags of sort.
"You evil clouds of the sky," Zecora shouted, "Attack us and you will go bye-bye!"
"Okay," Sandbar said to Zecora, "You're rhyming thing is really getting old. It's gonna make me catch a cold."
Sandbar realized he rhymed and facehoofs himself while Zecora just smiled smugly. Just then, they were almost hit with lightning and they look up to see the clouds coming after them. Zecora and Sandbar ran while throwing the bags after them. Some of the clouds dodged while others got hit, were frozen and fell down and got shattered. Suddenly, more bags popped up from sideways. It is revealed to be the cause of Gallus and Ocellus. This caused the clouds to scatter to try and find their assailants. The hypnotized Mane 4 and 2 of the CMC noticed this. But before they could do anything, Scootaloo and Starlight suddenly ran up to them.
"Hello guys," said Scootaloo.
"Long time, no see." Starlight said.
"Get her!" All the hypnotized villains said at once and they chased after her as she ran. Just then, Rainbow Dash and the alicorns peeked out of some bushes.
"Okay," said Rainbow Dash, "They're distracted. Twilight, you're up."
Nodding, Twilight used her magic to make them all teleport.
...
Just then, they teleported into the castle, most notably the royal bathroom, most notably the shower.
"Wow," said Princess Luna, "I must admit this bathroom's a lot more impressive than the one back in our castle."
"No time for that, Luna," said Cadance, "We must find Grogar's bell and use it against Bitter Taste."
Flurry Heart cooed in agreement.
...
The alicorns and Rainbow Dash sneaked across the halls and just barely hid when some clouds were patrolling.
Just then, they came to the throne room and noticed Grogar's bell near the throne on a pedastal and is covered by some small cylinder-shaped dome.
Flurry Heart was about to fly to it until Celestia stopped her.
"We can't just go frontal force and grab the bell," Celestia said, "Bitter Taste might have booby trapped it or worse, is planning a sneak attack."
Rainbow Dash put a hoof to her chin in thought and suddenly has a look of inspiration.
"I have an idea." Rainbow said.
...
Suddenly, shadows of what appeared to be Rainbow Dash and the alicorns were sneaking to the where the bell was. Soon enough, they surrounded the bell and just as the shadow that looked liek Rainbow Dash was reaching the bell, a bolt of magic came by and the shadows poofed away before 5 other beams went to the direction where the first beam came from and Rainbow Dash immediately 'dashed' to the bell to remove the glass case and grab the object. The five alicorns came to her with their horns glowing. Rainbow Dash looked smug at the silhouette that looks like Bitter Taste that is being captive by the alicorns horns.
"Well Bitter Taste," said Rainbow DASH, "How does it feel being outdone so easily since we used a bunch of cloud to make it look like we are trying to grab the bell so you would come out of hiding and we would grab you and..."
The alicorns brought the silhouette close to them...only it is also a bunch of clouds in the shape of Bitter Taste. The heroic ponies look taken aback.
"What in the...?" Twilight spoke up before the rest of the alicorns were suddenly hit with a beam of magic. Rainbow watched in shock as they all suddenly became mindless zombies as the beam rescinded. Rainbow Dash looked and saw Bitter Taste slowly coming up to them.
"How do you like that?" He asked rhetorically, "Trying to psyche me out when I was trying to psyche you out."
"Release them!" Rainbow ordered, "Now!"
"Or what?" Bitter Taste asked with no fear in his tone, "You can't use that bell unless you give it some magic and you don't have any magic with you."
He turned to the hypnotized alicorns, "Your majesties, do get that bell."
"Yes, master." The hypnotized alicorns said as they went to Rainbow Dash.
"Oh no." Rainbow Dash said in shock.
...
Rainbow Dash swooped out of the castle faster than you can say '20% cooler'!
She was about to meet her comrades until she saw that basically everyone in Ponyville has been turned into brainwashed zombies.
"Can this day get any worse?!" Rainbow Dash exclaimed in frustration.
Just then, a 5 headed hydra appeared straight out of the forest, also being mind-controlled and roared at Rainbow Dash's direction.
"I had to ask." Rainbow Dash said to herself bitterly.
With that, Rainbow Dash flew quickly as her wings could.
"After her!" Bitter Taste shouted as the zombified ponies followed Rainbow Dash.
...
Rainbow Dash soon made it into her Cloudaminium along with the bell. She looked out the window and saw the zombified ponies coming at a distance. She then lays down on her couch in angst.
"This is all my fault!" Rainbow Dash said as she began to cry, "I let Bitter Taste hypnotize me to be his puppet so he can rule all of Equestria! All because of some petty feelings I felt over past adventures. Why did I let those bitter feelings get to me?! Why couldn't I have been true to my element and stay loyal to my friends like I have during those times?!"
As she was crying, the zombified mob of ponies was nearing her house, but at that point, Rainbow Dash no longer cared as if nothing else mattered to her than wanting to finish what she started and end this whole mess. Her whole world want blank as she continued sobbing. As she did so, her whole body was being surrounded by red aura, but she was too full of sorrow to notice. However, Rainbow Dash's body began to feel tingly, which caused her to stop crying for a minute and notice her body.
"What in the name of Celestia..." Rainbow Dash began before her body grew brighter and suddenly, her eyes began glowing red and her body began to grow a little and some light came from her forhead.
...
The ponies came to Rainbow's Cloudaminium with the Hydra bringing one of its heads with Bitter Taste on it to said place of residence. It slowly put Bitter Taste on the cloud and he walked to the front door.
"Okay, Rainbow Dash," said Bitter Taste in utter frustration, "Are you gonna be an alicorn or do I have to make you? And before you answer, with the power I hold over your friends, I think you better choose wisely or else!"
Bitter Taste opened the door with his magic, but the moment he did, he was hit with a blast of red magic, sending him straight for the ground before a flash flies past the hypnotized pawns and ends up overlooking them. Bitter Taste looked up and sees that it is Rainbow Dash, only she is an alicorn and has red eyes and looks to be Twilight's height.
"What in the...how is she...?" Bitter Taste said before composing himself, "Well no matter," He addresses his hypnotized slaves, "Attack her!"
The ponies tried to attack, along with the hydra, but Rainbow thought quickly and shot a beam of magic at them at a quick pace that they cannot disarm. It was really quite impressive.. Bitter Taste could only watch helplessly as his hypnotized slaves were taken down with ease. As the last of his slaves were down, he watched and saw Rainbow Dash just got the Bewitching Bell. He gasped as Rainbow Dash used the bell, combined with her new powers, to return the magic to all of the ponies at a quick rate and its magic also shot far enough to the other kingdoms to give their magic and essence back. After that, Rainbow Dash turned to Bitter Taste.
"Bitter Taste," Rainbow Dash said, though her voice seems like it's echoing, "If you have any scrap of honor within you, end this insanity once and for all! Look at all the trouble you have caused because you wanted to take control over Equestria! Are using these innocent ponies who have done nothing to you to obtain your goal really worth it?"
Bitter Taste just said, "Are you kidding me?! You think I care about what happens to ponies like these? Why would I? Better yet, why would you? After all the heartache they gave you with no remorse whatsoever, you still wanna be loyal to these sorry excuses of friends?!"
Rainbow Dash looked incensed as she gave her reply, "Doe this answer your question?"
She immediately swooped down straight to Bitter Taste and Bitter Taste tried to run, but it was all in vain as Rainbow Dash got to him and used her newfound magic to keep him steady as she flew up to the stratosphere.
"What are you doing?!" Bitter Taste said as he fruitlessly tried to get out of Rainbow Dash's magical hold and he suddenly sees that Rainbow Dash is flying faster than the speed of light and is about to pull a Sonic Rainboom and given that she's gonna combine it with her magic, it looks like it's gonna be a the most spectacular one Rainbow Dash has ever made. Bitter Taste screamed his head off as Rainbow Dash got to the point of no return and soon enough, she made a Sonic Rainboom and it certain was the biggest one ever made as it certainly went over all of Equestria, it destroyed all of the anthropomorphic clouds, her cloud castle and the clouds beneath it and it certainly undid all of Bitter Taste's magic. It turned Spike, Smolder, Shining Armor and every other fossilized pony back to stone, Yona woke up, but was still hornless, Ember (who has returned to the Dragon Lands with her army) has the holes in her wings fixed, which she noticed and looked happy about.
Rainbow Dash came down to the former zombified ponies on the ground and she looked positively out of sorts as her horn disappeared and she returned to normal height and she passed out. The ponies all got up with dizziness in their heads. For Starlight, she noticed a light coming from her flank and sees that her cutie mark has returned. She gave a positively happy look. Soon enough, the ponies shook off her dizziness.
"Now I know how all of Ponyville felt when they were mind-controlled by Sombra." Applejack said.
"Tell me about it," Pinkie Pie said.
The ponies looked up above and noticed that the clouds and Rainbow Dash's cloud castle was gone.
"It would appear that somehow," Cadance said, "That Rainbow Dash managed to stop Bitter Taste and save all of Equestria."
The ponies all cheered at this.
"Look!" Rarity said as she pointed to Rainbow Dash's unconscious body. This led to the rest of the ponies to surround Dash in utter concern.
TO BE CONCLUDED...
