After discovering the Purple Dragons from the Turtles world had somehow ended up in the alternate world, the two teams set out to investigate.
After parking the Hauler in an alleyway, both Turtle teams and Rainbooms hid in another alley closer to the Dragons location.
Donatello spoke to the teams, “According to the news report, this is the area the Purple Dragons were seen last.”
“And there they are.” Applejack pointed out said gang who were making their way into a store.
“What do you think, April?” Donnie asked her who began concentrating.
“Something’s wrong. I sense the Dragons but I don’t sense Hun anywhere.” she answered.
“Either way, there are innocent lives at stake! We need to strike now!” Leonardo answered while prepared to engage.
“Maybe some of us should keep an eye out for Hun?” Starlight suggested.
“Yeah. I don't know about your Hun, but ours is pretty clever.” Sunset added.
“There isn't time,” Leonardo replied, “We have to stop them before they hurt someone.”
“Besides, if dese boozos are anythin' like aur Hun and Purple Dragons, dis'll be a snap!” Raphael put in confidently.
“I wouldn't be that arrogant if I were you, Raphael.” Rarity warned him.
“Well, yahr not me.” Raphael replied.
“Which is for the best.” Michelangelo said, only to receive a grunt from his brother.
“Since you took our Purple Dragons by surprise by showing up instead of us. We'll do the same.” Leonardo instructed.
“Works for me.” Donnie admitted.
“Alright, but be careful.” Leo warned them.
“We got this.” Michelangelo replied, as the other turtles and their Casey proceeded, while the others waited back.
“Are you sure it's safe letting them take the first strike, Leo?” Princess Twilight asked.
“To be honest, I'm not sure,” Leo admitted, “But we got to believe in each other. Besides we still need a chance to keep an eye out for Hun.
Meanwhile the Purple Dragons had just smashed an electronic store window, before scoping the place out. One member looked at a bunch of CD players, “This stuff is so low grade!”
“Seriously, who uses these anymore?” another asked.
A female member spoke to Fong; one of the original three members, “Yo, Fong, you sure the Turtles are gonna show up?”
Fong answered confidently, “That's what Hun's plan is. Those shell heads can't resist helping folks in trouble!"
“Exactly!” Came Leonardo's voice from the shadows.
“Huh?” Fong wondered, as four figures flew from the shadows and knocked Fong, and three more of the Purple Dragons off to the side.
They got up and saw the other turtles looking ready, before Jones arrived, “I think you've all caused enough damage here tonight.” Leonardo warned them.
The Purple Dragons looked confusingly at the turtles and Jones, before Fong had to ask, “Who are you guys?”
Tsoi answered him, “They kind of look like the ninja turtles.”
“Duh! We are ninja turtles.” Michelangelo answered.
Another member took notice of Jones, “And ain't that Casey Jones?”
“In da flesh.” Jones answered.
“He's too muscular to be the Casey Jones we know.” Fong replied, while outside Casey scowled at what Fong was insinuating about him.
“We can assume you guys were expecting someone else?” Donatello asked rhetorically.
“Yeah,” Sid admitted, before clearing things up, “I mean, you're not the turtles we were counting on showing up!”
“Well, sorry to disappoint you, but you'll just have to deal with it.” Leonardo answered.
“Whatever you turtles are, this neighborhood is ours! So slither back to the ocean you came from!” Fong warned them.
Donnie face palmed, “Seriously? Did he not listen to what I said the first time he said that?”
"Wouldn't blame him," Raph admitted, "Even I barely listen to what you say." Donnie scowled.
And just like Donnie, Donatello had the same reply, “Technically, we're fresh water turtles.”
“Less tawkin', more butt kickin'!” Raphael interrupted, wanting to get the fighting over with.
“Get'em!” Fong ordered the Dragons who got ready.
“It's Ninja Time!”
And so the Turtles and Jones engaged the other Purple Dragons like they always did with theirs. Soon the gang was knocked to the ground before they got up and ran away.
“Well, that was fun.” Michelangelo told his bros.
“Yeah, no matter what dimension Purple Dragons are still Purple Dragons.” Jones agreed.
“Hey, you hear something?” Leonardo asked, as they heard a beeping sound.
They all looked down and saw a device roll up to their feet before it exploded sending the five flying back. The turtles landed on their shells and Jones on his back.
“Thank goodness for thick pads.” Jones groaned.
They saw the Dragons had returned, “You didn't think we were gonna give up that easily, did you?” Sid asked rhetorically.
“But we sent you runnin'.” Michelangelo recalled.
“It's called acting!” a female Dragon answered.
“And if you thought that explosive was a hit, then you're gonna love this.” Fong added, as the Dragons whipped out Kraang blasters.
“I'm not loving this!” Michelangelo feared.
“What da shell are those?” Raphael asked.
“Just some weapons our boss looted from TCRI, before we ended up here.” another Purple Dragon answered.
“TCRI?” Donatello asked in shock, “That would mean those weapons are Utrom technology!”
“Utrom?” another female Purple Dragon asked in confusion, “These are Kraang weapons, Nerdtile!”
“Let's see you guys try and take us on with these bad boys! Round 2, Turtles!” Fong announced, as the Dragons started attacking the turtles and Jones with their new weapons.
As the turtles dodged the laser shots and attacked the Dragons up close, Jones was doing his best to avoid more lethal shots, “Wow. And I thought our Dragons newest arsenal from when they stepped up was big, but these guys are really packin'.”
The Turtles and the Rainbooms watched knowing if their Purple Dragons were really packing Kraang tech then they'd need to join the fight.
“Come on!” Leo called, as they jumped into action.
“Hey, Dragon Creeps!” Rainbow called.
The Purple Dragons stopped and saw them, “Look, Fong, it's our turtles.” one of the male members noticed.
“And the Rainbooms too?” Sid asked.
Fong smirked, “Well, this is gonna be extra fun.”
“Fun for us, you mean.” Casey said, as he readied his hockey stick.
“Get'em!” Leo called, as the groups tag teamed and engaged the Purple Dragons.
As Leo and his counterpart fought side by side, Leo just had to ask him, “So, your thoughts on our Purple Dragons?”
“Ok, I'll admit your dragons are formidable foes. Especially when they're packing weapons like that.” Leonardo admitted, as they started forcing the Dragons outside the store and onto the streets.
As Karai, Shini, April, and Sunset were working together against a couple of the Dragons deflecting their laser shots back at their weapons. Finally, April used her telekinesis to levitate the rest of their Kraang weapons our of their grips and crushed them.
“Good one, April.” Sunset commended her, until April started sensing something.
“Oh, no!” she gasped.
“What is it?” Karai asked.
“Hun...” the girls gasped and got ready for when he would strike.
As the other turtles stood ready against the rest of the Dragons, Leonardo spoke, “Now matter what weapons you use, we'll still be victorious. Because ninjas never quit.”
“How pathetically naïve.” came a new voice.
The other turtle were suddenly whacked into a wall and looked up to see mutant turtle Hun towering over them, “Who da shell are you?!” Raph asked in shock.
“You may call me... Hun!” he let out a roar.
“That's Hun?!” Jones gasped in shock.
“Yeah. Shocking, huh?” Keno asked.
“He looks like an ugly version of Bruce Lee.” Michelangelo noted.
Hun frowned, “You'll regret saying that.” he began attacking the four other turtles with his brute strength, while the turtles relied on their ninja moves.
As Raphael dodged some of Hun's strikes, he felt the urge to mock him, “Man, and I taught our Hun was ugly, but you look like somethin' aur toilet spit up!" Hun responded by slamming his fist into his gut, knocking the wind out of him, then grabbed him by the leg and used him to smack his brothers off their feet,and finally body slammed him all over, “But you're definitely stronger.” he groaned.
“Anything else you would like to say?” Hun asked, as he was about to squish him.
“I got one for you,” Michelangelo said, as he and Donatello jumped above him with their feet sticking out, “Surprise!” the two delivered a double kick to Hun knocking him off balance, allowing Raph and Applejack to take Raphael to safety.
Hun growled at the two other turtles and began attacking them. Michelangelo and Donatello dodged several attacks, before Hun eventually grabbed them by the heads and knocked them into each other before dropping them.
“I'm seeing atoms.” Donatello groaned, as atoms were spinning around his head.
"I see pizza." Michelangelo groaned as pizza slices circled his own head.
“Soon you will be seeing death.” Hun was about to smash them, until Applejack slid in and caught Hun's fist with her bare hands.
“I don't think so!” Applejack replied as she pushed Hun back making him stand atop a diamond shield Rarity conjured under him.
“Watch your step,” Rarity said, as she made the shield fly forward causing Hun to slip off and land on his back, “Whoopsie.” she giggled.
Hun growled as he got up, before speaking, “If I can be honest, I did miss these little fights.”
“What a coincidence, so did we!” Pinkie said, while bouncing around him.
“She calls this fight 'little'?” Donatello asked in confusion.
Hun tried attacking Pinkie, but being who she was slipped away which got Hun more irritated, “Enough of this!” Hun picked up a car and held it over his head.
“Oh, jeez.” Jones gasped knowing this was going to cause some damage.
“Once I crush all eight of you turtles, we'll be dining on turtle soup.” Hun promised.
“Not tonight,” Leo replied, before speaking into his T-Phone, “Now, girls!”
Before Hun could chuck the car right at them, he was rammed by the Hauler that squashed him against another building knocking him unconscious.
“Oooh, that's gonna leave a mark.” Michelangelo cringed.
“What just happened?” Raphael asked.
The door of the Hauler opened up to reveal the CMC, “A little rescue from the Canterlot Movie Club.” Apple Bloom answered.
“Booyakasha!” Sweetie Belle and Scootaloo cheered.
“Wait, how'd you get the keys to the Mauler?” Leonardo asked in confusion, until he heard innocent whistling coming from Karai, “You didn't.”
“I totally did.” Karai smirked.
“Well, that takes care of the big guy.” Keno motioned to the knocked out Hun.
“Let's finish this.” Leo declared.
“Together.” Leonardo finished, as the group took out the rest of the Purple Dragons.
Fong seeing the tides have turned against them knew a retreat was in order, “Let's get out of here!” he quickly threw a small explosive that kept the ninjas at bay, so the Dragons could escape with Hun.
April suddenly heard incoming police sirens, “We better get out of here!”
The girls helped all the turtles back up, and especially Raph who was injured the most from Hun's slamming, “So where to?” Apple Bloom asked.
“Uh.. She's not driving, is she?” Michelangelo asked Applejack who didn't have time to respond, as Apple Bloom answered for her.
“I'm not even old enough for a learners permit. I was just asking.”
“I'm too weak to drive. Can you, Donnie?” Donatello asked.
“I'll try,” he got into the driver's seat, “Can't be too different from the Shellraiser.”
As the group piled in, a beeper went off, and April answered it to see it was her adult counterpart, “Bring the guys back to the lair. Quickly.” she instructed.
“We're on our way!” April answered. And so Donnie drove the Hauler away heading back to the lair before the squad cars could arrive.
After arriving at the lair, O'Neil ran to help them over to the benches, “Guys!”
Splinter rushed over as well, “My sons!”
“Is everyone ok?” Fugitoid asked.
“If by okay you mean, we're in excruciatin' pain! D'hen, yeah, we're just peachy!” Raphael said in sarcasm.
“I can't feel my anything!” Michelangelo groaned.
“It really was our Purple Dragons and Hun.” Sunset confirmed.
“We know. We watched everything on the monitor.” Fugitoid motioned to said monitor.
“And I thought our Hun was tough, but that guy?! He's like a machine!” Donatello said in disbelief.
“A war machine!” Michelangelo added.
“Yeah. I felt the same way when I first fought him,” Casey said, “And he was still human.”
“You guys need first aid, and fast.” O'Neil said, as she was about to grab something.
“Actually, April, me, Princess Twilight, Sunset, and Starlight have something that might help.” Leo offered.
“What is it?”
“It's better if we show you.” Princess Twilight answered, much to the others curiosity. They look to Master Splinter, who nods, giving them permission. Then they lay the Turtles on the floor.
“Okay, guys. Just relax.” Leo instructed.
“Um, this isn't gonna hurt, is it?” Michelangelo asked nervously.
“Quite the opposite, actually.” Starlight answered, as they started forming hand signs.
“Rin. Pyo.” Leo began.
“Toh. Sha.” Princess Twilight continued.
“Kai. Jin.” Sunset Shimmer followed.
“Retsu. Zai. Zen!” Starlight finished.
Their hands glow and they place them on each of the Turtles: Leo on Leonardo. Princess Twilight on Donatello. Sunset on Raphael. And Starlight on Michelangelo, as they continued.
“Mu. Ryo. Ju. Son. Mu. Ryo. Ju. Son. Mu. Ryo. Ju. Son. E. Sai. Nyu. Rai!”
When they finished, the turtles all got up as if they were never hurt at all, “What da shell?!” Raphael gasped, as he moved around as if his body wasn't broken.
Michelangelo leaped to his feet looking excited, “Woohoo! I feel like a million bucks!”
Donatello was so befuddled, he can't find the words, “What? How? Where? Huh?”
“Well, that leaves out Why and Who, doesn’t it?” Pinkie asked, as she, Mikey, and Rainbow chuckled.
Leonardo turned to his counterpart in equal shock, “What did you just do?”
“It’s a technique our Master Splinter taught me. It’s called the Healing Hands. It’s helped us a lot in the past.” Leo explained.
“It’s how Father got the mind worm out of me.” Karai added.
“Leo taught the three of us the first time the guys came to Equestria after healing a guard with it.” Princess Twilight put in.
“So dat little trick of yours can heal just about anythin'?” Jones asked intrigued.
“Anything. Not everything.” Starlight replied.
“I've got to learn to do that.” O'Neil said sounding as intrigued as Jones.
Leonardo looked over at Leo, and spoke, “Leo. You and your team fought well. Now I see exactly what both teams of Purple Dragons are capable of.”
"Thanks. After facing yours I can see what they both can do as well."
"We may come from two different universes, but we all have a common goal. To bring justice to the city we love.”
“And that's a fact.” Applejack said.
“And to show you our appreciation, I present to you, the eternal pizza!” Mikey held up a disgusting slice.
Leonardo and his bros looked repulsed, “Uh, I think we're good, Mikey.” Leo answered.
Michelangelo spoke up, “I'll take it!” he took the slice and ate it, before noticing everyone staring at him, “What? I was hungry.”
“I hope you puke that up later.” Raphael said, as the CMC chuckled.
Splinter spoke up, “I am proud to have seen such fine teamwork between all of you.”
“Thank you, sensei.” the group bowed their heads.
Shini suddenly noticed a worried look on Sunset, “What's wrong, Sunset?”
“I'm just worried. How did the Purple Dragons from our world come here?” she answered.
“Could've been a Kraang portal.” April suggested.
“Your Purple Dragons did mention their Hun looted Kraang tech from the TCRI building in your world.” Leonardo recalled.
“Maybe, but still...”
“Another thought came to me,” Donatello spoke up, “If their Purple Dragons got here, who knows who else might've got here as well.
“Aw, crud/sewer apples!” the Raphs cursed.
“Looks like we may be here for awhile.” Princess Twilight told Splinter.
“I'll bring out the spare blankets.” Splinter said.
“If there are more enemies of ours in this world, we'll find them.” Leo promised.
“And we'll do it together.” Leonardo smiled, as Leo smiled back before the two locked fists.
