New Heroes were surrounding Canterlot Castle underneath the dark of the night. They were not letting anypony in or out. The only other ponies inside were the princesses and the original heroes. They were standing in the gardens all worried about what what might happen next.
"I wonder what they've got in store for us?" Heatwave said.
"Stretch here discovered that the Siren Sisters hypnotized all the New Heroes," Slapstick said, "And they brought us all here to get rid of us."
"Do you believe everything your rubber chicken says?" a fancy unicorn with a monocle and blue mustach asked.
"Ever since I ignored him when he told me my cat, Mr. Featherbeak, was actually a parrot." Slapstick replied. "Took us all by surprise. And who are you anyway?"
"The Dirigeant." the fancy hero said. "I have the power of mind control."
"Well, then why don't you snap the New Heroes out of it?" Soaron asked.
"I tried." the Dirigeant said, "But I just can't seem to reach them."
Suddenly, Anar D appeared in the sky holding up Power Tower. He shoved it inside the castle and the Siren Sisters appeared on the balcony looking down at the original heroes. Serena was in front and glared marvelously at the hostages below.
"This day is going so perfect
The kind of of which I dreamed since I was small
EVERY HERO AT OUR MERCY
AS HELPLESS AS THEY'RE MEANT TO BE
AND SOON, ALL OF EQUESTRIA WILL FAAAAAAAALL"
"Serena, Carol, Melody," Princess Celestia declared, "Release us now!"
"Not going to happen, princess!" Serena said. "Carol, give us our amulets!"
"Oh," Carol said nervously. "Actually, I think I left them inside the tower."
"You left them inside the tower?!" Serena asked angrily. "Seriously, why did I think you could do this, this one simple thing? It's like I'm talking to a chicken."
"Hang on," Carol said.
"A really, really, big, stupid chicken named Carol," Serena growled.
"Ouch," Carol said.
"And do you want to know something else," Serena asked. "I never liked your tacos!" That made Carol gasp. "NEVER!" That very comment made Carol whimper.
"Hey, losers," Melody said, "You're embarassing us in front of the doomed."
Serena sighed heavily. "Carol, get inside and get the stones."
Carol turned around and entered the tower. She went across a few rooms and found the red rocks. She picked them up and sighed for a second.
"What am I doing," Carol asked herself. "I work myself to death doing the best I can, but Serena and Melody can't see it. The Power Ponies are failing right now, but they're not yelling at each other. And another thing, I'm finally going to get what I want out there, so how come something so right could feel so... wrong."
"Maybe because it's not right."
The Doctor appeared out of nowhere and right in front of Carol.
"Who are you," Carol asked.
"The Doctor."
"Well, doc, what are you talking about," Carol asked. "What do you mean that nothing I'm doing is right?"
"Because it's not what's meant to happen," the Doctor said. "And I think you know it also. Why in this entire Multiverse would you want to hurt innocent ponies?"
"Serena said that it's because they hurt us in the past," Carol said. "We're just getting even."
"You really think getting even will change what has happened," the Doctor asked. "Child, you're blaming the world for your life being saved when you can use your gift to spread kindness to the world."
"But it would've been nice to just go back to the way things were," Carol said, "Just to not be different; just to be... normal again."
"Are you kidding me?" the Doctor asked. "Everywhere I go, ponies I meet would attempt to make themselves very noticed. They want to feel special. You're lucky, if you ask me. Answer me this: why be different when you can be rare?"
Carol looked at the rocks in her hands. She then see them glow in a rainbow of colors. She felt the same feeling coming from her own eyes. She knew just what to do.
Outside the castle, the Power Ponies peeked in and saw Serena and Melody at the Power Tower balcony waiting for their sister.
"All right," the Masked Matterhorn whispered. "As soon as they're vulnerable, we strike. We'll force them to release the New Heroes."
"What if they send Anar D after us?" Zapp asked.
"You're talking about me, I presume?"
Anar D appeared right next to the Power Ponies.
"How'd you know we were here," the Shadow Blot asked.
"I could sense another alicorn a mile away," Anar D said. "Look, I can't help you here." He changed his head to Serena's. "I'm a slave to the blonde bugaboo now." He changed his head back. "What are you going to do?"
"Just stall them until we get to them," the Masked Matterhorn said.
"That, I can do," Anar D said. He warped himself right next to Serena.
"What do you want," Serena asked. "You know you can't escape me while I have the box."
"That's true," Anar D said nervously. "I was just wondering... what time is it? Remember, I get regular coffee breaks."
Carol walked out onto the balcony with the red stones in her hands. Her head hung low.
"Good girl, Carol," Serena said. "Now, let's get this party started."
Anar D was sweating and he gulped.
"No." Carol sighed.
"What," Melody asked. "What do you mean, no?"
"Lord Arcanus expects us to release him tonight," Serena said.
"I... said... NO," Carol shouted. "You two are the worst sisters in history! And everything the other ponies said was true! Like how you're a couple of..." To keep the story child-friendly, this part of the dialogue can't be revealed. Everyone was surprised at what they heard. Even the heroes and villains outside were shocked. "Well, here's something for you: I'm sick of being evil, sick of being loyal to Arcanus, and most of all, I AM SICK OF YOU! SO... I QUIT!"
"Preach, sister," Anar D exclaimed. "PREACH!"
"And guess what," Carol continued, "Arcanus will never return because he needs all three of us to cooperate. So now, you two are going to pucker up..." She pointed at her backside. "...and plant a big, wet one on my..."
Suddenly, Serena bent her knee and kicked Carol off the balcony. Slapstick caught her, but Carol dropped the red stones at the balcony and Serena picked them up.
"Stupid Carol." Serena said. "We don't need her specifically. Anar D..."
"Whoa, no way!" Anar D said. "You CANNOT make me sing back-up!"
"No!" Serena shouted. "I just want you to create a copy of Carol with the same Siren magic."
"And give her an estimated I.Q. of 0." Melody added. "That way, she can be smarter than the original."
"HOLD IT RIGHT THERE!"
Suddenly, the Power Ponies, Mighty Machines, and supervillains appeared and entered the gardens. They stood with the original heroes and the princesses.
"I'm impressed, Masked Matterhorn." Princess Celestia said.
"You're not the only one with an army." Zapp said.
"Looks like you've got some upgrades," Melody said. "But it doesn't seem like you had to scrape the bottom of the barrel for these amateur villains." The villains growled.
"Actually, we have an edge," Serena said. "The only way you can reach us is if you get past the New Heroes. And you wouldn't dare hurt them."
The New Heroes moved. They gathered up around Power Tower and turned to the original heroes and the supervillains.
"ALL HAIL ARCANUS!"
"Well, I have no problem with hurting them," Gryphon Galore said. "Never was a fan anyway."
"All right, every pony," the Masked Matterhorn said, "We've got to get to those Siren Sisters before they drain the life force out of the New Heroes! Save the New Heroes! Save each other! SAVE EQUESTRIA!"
At that moment, the heroes and villains charged toward Power Tower. The New Heroes charged at the other and an all-out battle exploded.
