After the fight the heroes returned to the lair with Spike overjoyed to see them all ok, but was edgy upon seeing the Dazzlings. After Twilight calmed him down and told him things were different he took her word for it.
Soon enough the heroes were celebrating with a pizza smorgasbord, with the Dazzlings getting to know each of the Rainbooms and mutants and found out they had more in common than they thought.
With Adagio she was talking to Leo about their positions as leaders, "Ever since we arrived in this world, it's been a nightmare trying to keep Aria and Sonata under control, but with Sonata's density and Aria constantly questioning my decisions and ideas it's been one headache after another."
"I hear ya. It's hard to keep my own team in check, especially with Raph questioning my own decisions and not waiting for orders. But he eventually realizes the importance of following my lead." Leo admitted.
"Boy, we got our work cut out for us, huh?" Adagio asked.
"For real." Leo agreed.
Over by Raph and Slash, Aria was talking to them, "It's not that I don't think Adagio's a bad leader. I just wonder if the stuff she comes up with is seriously the best choices she could make."
"I can understand that," Raph admitted, "I mean I once tried to be leader, but I cracked under the pressure."
"And I almost lost faith in my role as a leader." Slash sighed.
"If I had it my way I probably wouldn't have had the knowledge to come up with any better ideas." Aria added.
"Hotheads like us certainly have a lot to learn." Raph said, as she and Aria fist bumped.
Finally Sonata was enjoying pizza with Mikey and Mondo, "Mm, next to tacos, pizza is my favorite food." Sonata beamed.
"It's a food sent by the heavens." Mikey added.
"For real, dude." Mondo agreed.
"I mean, you just don't get this kind of stuff back in Equestria." Sonata said, as she ate a slice.
Suddenly the lights dimmed, and everyone saw the Rainbooms with their instruments in hand looking ready to play.
Rainbow spoke up, "Listen up humans and mutants alike. This is a little number thought up by our dear friend Fluttershy in dedication to the four greatest friends we ever made here. This one's going out to you, Ninja Turtles!"
And so the band started playing, as Twilight and Sunset led lead vocals with each of the girls taking a few verses. As they played, like always they ponied up.
As the girls played the turtles and their friends were enjoying the rocking beat, especially Casey and April. The Dazzlings though bitter about giving up their voices knew once they learned how to sing again through the right method would one day be able to match them again.
When the Rainbooms finished their pony features vanished, while the mutants cheered and applauded on their performance.
"Alright!" Mondo cheered.
"Hooray!" Pete clapped.
"Jolly good!" Rockwell applauded.
"You girls were amazing." April congratulated them.
"You rocked." Casey added.
"Thanks, girls," Leo began, "We appreciate that dedication."
"Of course. What're friends for?" Twilight asked.
"Come on, we're more than friends," Mikey said, "We're like a big family."
"Took the words right out of my mouth." Pinkie smiled.
Later on after the Mutanimals left, the Dazzlings were still in the lair with the turtles and Rainbooms. Twilight spoke to Adagio, "So now what're you girls going to do?"
"The girls and I decided to leave New York and start fresh somewhere else." Adagio answered.
"But where will ya go?" Applejack wondered.
"No idea. We'll just go where the wind takes us." Aria replied.
"Are you sure you won't consider coming back with us?" Sunset asked.
"Sorry, but unlike you I doubt anyone at CHS would forgive us ever." Sonata answered.
"You'd be surprised. I mean after doing plenty of community service and what not." Rainbow said.
"Thanks, but we need to do this." Adagio replied.
"And it's not like we'll be totally defenseless out there," Aria added, "We still have our ninja skills. Except this time we won't use them to hurt others, but to protect ourselves and each other."
Splinter said, "See that you remember that."
"We will, Master Splinter." Sonata promised.
"And remember if you need anyone to talk to, we're always welcomed to you three." Rarity added.
"We really appreciate this girls." Adagio smiled.
"Well, we better get back, tomorrow's a big day." Twilight said, as they all agreed and left the lair.
The next day in an alley way, the Dazzlings were saying goodbye to their new friends, while the Rainbooms had either hidden their ninja weapons in their bags, or wrapped the bigger ones in cloth so no one would know what they were, "Thanks for everything, you guys." Sonata began.
"No prob, Sona. If ya ever come back to New York drop us a line." Mikey said.
"We'll keep that in mind." Aria replied.
"Girls, there's our bus." Adagio said, as a bus was pulling up next to the bus stop.
So the Dazzlings left, as the group bid them farewell, before they got on the bus that took off. Twilight spoke to their new friends, "The next bus will be ours back home. We're sure gonna miss, you guys."
"We will too, Twilight." Leo admitted.
"You girls have been the best thing to happen to this city since it was saved." Casey added.
"So we'll still keep in touch, April?" Rarity asked.
"You bet, Rarity." April confirmed.
"And, Casey, when I come back let's have a little one on one hockey match?" Rainbow challenged.
"Lookin' forward to it, Dash." Casey and Rainbow locked fists.
"Girls, there's the bus." Fluttershy said, motioning to the incoming bus.
"Guess it's time to go," Pinkie said before bawling and embracing Mikey, "I'm gonna miss you, Mikey!"
"And I will you, Pinkie Pie!" Mikey bawled.
"Alright, you two, get it together." Raph said, as he and Sunset pried the two apart.
So the girls walked to the bus stop and got on the bus with Twilight the last one to get on. They took their seats, as Twilight looked up and saw the turtles standing on top of the roof of a building.
She smiled and thought, 'Sayonara, Ninja Turtles.' and the bus took off, while the turtles watch it drive off and out of the city.
Sometime later back at CHS, the girls were gathered around the school statue with Twilight and Spike ready to go through the portal.
"We'll see ya again soon, Twilight." Applejack said.
"I hope so to. It's gonna be interesting explaining to your Equestrian selves what I had to go through." Twilight admitted.
"Well, it'll be more believable on your end. I doubt anyone here would believe that we fought evil ninjas along side mutants." Rainbow said.
"Guess, this will be something we'll have to keep to ourselves." Fluttershy added.
"As long as we know then that's all that matters," Twilight assured her, "Ready, Spike?"
"All ready." Spike answered, as he still wore the Hamato clan headband. And so the princess and her assistant went through the portal.
Meanwhile back in Equestria in Twilight's castle, the pony versions of the girls were awaiting the return of their friend having gotten the message from her via Sunset Shimmer and the notebook.
The mirror glowed as Twilight stepped out back on all fours as her weapon was still strapped to her back. And Spike still wore the headband.
"Twilight, welcome back." Fluttershy greeted her.
"We sure missed ya." Applejack said.
"Are you and Spike ok?" Rarity inquired.
"We're both fine." Twilight assured her.
"So what'd ya do in the other world?" Pinkie wondered.
"Betcha had some big adventure, huh?" Rainbow guessed.
"You don't know the half of it." Twilight answered.
"Well, what happened?" Applejack wondered.
"Well, I learned how to be a ninja." Twilight answered.
"And I turned into a mutant." Spike added.
The girls gave them confused looks, as Rarity spoke, "You may have to start at the beginning."
"Right." Twilight said sheepishly, before she used her magic to remove her weapon from her back an unravel the cloth wrap.
"Whoa, where did you get that?" Rainbow gasped.
"This was the ninja weapon I was chosen to use. But for now it'll make a good trophy," she levitated up onto a stand above the fireplace, "Perfect."
"So can you tell us the story now?" Pinkie pleaded.
"Ok, ok. Calm down, Pinkie. Let's go to the meeting room, and we'll explain from there." Twilight said, as the group left the library, before Twilight took one last look at the portal and smiled hoping one day she'd see not only her friends from CHS soon, but her mutant friends as well.
Months Later
Twilight and her friends were in the library as the group was helping reorganize the place, until the portal looked like it was going haywire.
"What's going on with the portal?" Spike asked in worry.
"I don't know." Twilight answered in equal worry.
"It's gonna blow!" Pinkie screamed.
"Take cover!" Applejack called, as they all took cover behind something, until the portal released steam from overload.
Twilight and Spike looked and saw piled right by the portal was a group of ponies. They recognized one as Sunset Shimmer who was once again a unicorn. And the others were the counterparts of the Equestria Mane Five including what looked like another Twilight and another Spike.
The Mane five of CHS looked like their pony selves now only were dressed in their same clothing, even their back hooves still had the same footwear. The Twilight was the same Twilight Princess Twilight met when she finally got back to Sunset Shimmer on her problem about the magic leaking into the Friendship Games. She retained the same glasses and had her hair in a pony tail, while continued to wear the Crystal Prep uniform.
"Girls?" Princess Twilight gasped, as she galloped over, "Are you ok?"
"We're fine." Sunset groaned, as she and the girls got up.
"Girls, we're really ponies!" CHS Pinkie beamed.
"My stars." CHS Rarity gasped.
"Well, I'll be." CHS Applejack admired.
"So awesome." CHS Rainbow cheered.
"My goodness." CHS Fluttershy gasped.
"This is interesting." CHS Twilight admitted.
"I'll say." Dog Spike said, while looking at his reflection in the mirror.
"What're all of you doing here, and what's wrong with the portal?" Princess Twilight asked.
"About that..." Sunset trailed, as CHS Applejack spoke.
"Could we stay here for awhile?"
"What? Why?"
"Because our world is gone, darling." CHS Rarity said with sorrow.
"Gone? How?!" Princess Twilight asked in confusion.
Pinkie explained,"Ya see a dinosaur alien race called the Triceratons invaded the earth in order to destroy the Kraang that were still there. By doing so they used a black hole machine which opened up a black hole and sucked in the entire planet and everyone in it. So we escaped using the portal on our end, but with it gone we have no way of getting back not that there's a planet to go back to." she grinned.
Princess Twilight, Spike, and the Equestrian Mane Five were slack jawed, as CHS Twilight spoke, "That pretty much says it all."
"Uh-huh." Dog Spike confirmed.
"Oh, my gosh, I'm so sorry,' The princess comforted them, "Wait a minute, the Kraang? Then the turtles, April, Casey..."
"We don't know if they made it out." Sunset sighed.
The princess spoke, "If I know them they had to have found a way to escape. Maybe they'll even fix what happened."
"But how?" CHS Fluttershy asked.
"I don't know for sure. Sort of a gut instinct."
"Well, if they do have a plan to save the planet all we can do is wait." Applejack said.
"So about us staying here?" Sunset asked.
"Don't worry, you're welcomed to stay as long as you want," Princess Twilight began, until she and Spike remembered both their Equestrian friends and their human counterparts seeing each other, "But first I think some introductions is in order." she said knowing it was going to be awkward to introduce both groups to each other.
