Also, for the next generation, the couples are mixed. Bye! Enjoy!

Clash! Clash! Clash!

Many blades were heard clashing and he fought with bravery, honor and no hesitation, gripping tightly to his twin katanas as he looked at his hooded enemies' eyes.

Leonardo was visiting the Battle Nexus and had just stepped in the Daimyo's palace when he was suddenly attacked by a group of hooded creatures. They were all ninjas, as far as he could tell but their weapons were all mixed with those of a samurai.

Anyway, Leo pushed back one of his opponents, sending the hooded ninja back before it took a fall.

" Ha! Take that!" he scoffed before blocking another pair of blades.

They were a pair of twin katanas that resembled his own yet their handles weren't blue but were gold with a bit of black.

As he defended himself from said blades, he noticed that his ocean blue eyes were staring straight at furious grey ones and that his foe had a green furry hand.

Green fur? he thought, confused at what he was seeing. How is that even possible? What kind of ninja creature am I dealing with?

Since he was too busy thinking, he wasn't able to see another hooded creature with chocolate brown eyes and peach skin holding out a bo staff with dark brown rope wrapped around it's middle part standing behind him. The said foe tripped Leo over between his legs, causing the said turtle to fall over on his plastron. He looked up to see another hooded creature with midnight blue eyes and white skin holding out and pointing a katana with a black handle similar to his friend Usagi's.

" Who are you?!" he demanded, his hands moving towards his blades little by little.

" Your worst nightmare." the ninja replied before swinging the blade in it's hand towards the weak turtle.

Leo saw this coming but as he held out his katana to defend himself, it shattered into shards and the last thing he was able to do was scream for help as the ninja swung another blade towards him.

" HEEEEELP!"

Leonardo's eyes widened as he jolt awake and sat up on his bed with him breathing heavily. Cold sweat went down from his head as he kept on panting for air.

Whatever just happened, it was just a dream. A nightmare, nonetheless.

He wiped his sweat off and placed a hand on his chest to help his breathing go back in a steady pace.

What was that? he asked in his thoughts. Was that all a dream or a warning? Who were those guys that I fought? Were they real or just an illusion?

Leo sighed in defeat and turned over to the digital clock on the desk near his bed.

5:30AM.

He sighed, knowing that he was 30 minutes late from his usual wake-up call. He got up from his bed and placed on his mask before heading out of his room and down into the dojo then he began to train, his train of thoughts focusing on what he dreamt about.

Who were those ninjas? Were they really going to fight him? Why fight in the Daimyo's palace?

Suddenly, a terrible thought sent a chill down his spine.

Will it intervene with me and my family's visit to the Battle Nexus for the championship?

After a few minutes of training, he grabbed a towel and wiped the sweat off of his head then he walked out of the dojo and went to the kitchen. He had been training for 15 minutes already so he wasn't surprised to see his little brother almost finished making breakfast.

Michelangelo whistled a happy tone as he cooked pancakes with French toast and orange juice while making green tea for his big blue clad responsible brother and brewed coffee for his genius purple clad brother. He was about to take out the last of the pancakes from the pan when he saw his big brother from the corner of his eyes.

" Hey, Leo!" he greeted with a smile and a wave using his free hand but he didn't turn." What's up?!"

" Oh, hey, Mike," Leo greeted back but in a blunt tone as he sat down on his seat and looked down as he drank his tea.

Mike got concerned on his tone so he placed the cooked pancake on the nearby plate, turned off the stove and turned around.

" Um, hello! I asked what's up! Where's my answer?!"

Leo looked up at his little brother and sighed.

" Oh, right. Sorry,"

Mike shook his head and grabbed the plate of pancakes then he made his way to the table, placed the plate down next to the plate of French toast and sat next to his big brother.

" Hey, you okay?" he asked.

" Well, not really," Leo replied with a sad sigh." I kinda had a nightmare,"

Mike was taken back." Woah, seriously? That's new. What's it about, dude?"

" I-I-I'm not sure. I have no idea,"

" What do you mean?"

" I mean, in my nightmare, I-I was attacked by a group of ninjas in the Daimyo's palace. They defeated me and were about to finish me off when I woke up,"

Mike blinked at his responsible blue clad brother.

" Woah. So, it had something to do with our visit to the Battle Nexus for the championship?"

Leo sighed again and nodded.

" Afraid so. Now, I'm fearing that those ninjas are real and that they're going to do something bad to us and our friends,"

" Yikes, bro. Are we gonna tell the others about this?"

Leo shook his head." No, we can't tell them. Not yet, at least. We can't let them worry over something that we don't know that exists. We have to make sure first. Can I count on you to help me?"

Mike smiled firmly and nodded, doing a salute. Leo smiled back then they ate their breakfast ahead of their brothers.

Splinter stood by the lair entrance, waiting for his sons, who were in their rooms to get theirselves ready.

It was already starting to get dark and the five of them had to get a portal open to the Battle Nexus before it got late. They've been training for the whole day just for the championship and now, it was almost late so they had to get going before the contest started.

Anyway, after a few minutes, the four turtles finally joined their father at the door then they went on their way to an alley way up on the surface. Splinter drew out the portal and chanted a chant, letting a water-like portal open in front of their eyes. They entered it and were soon transported to a place filled with plants near a huge palace.

Raphael took a deep breath and said," Aah, its good to be back in the Battle Nexus,"

" Yeah," Donatello agreed, nodding.

Leo and Mike nodded with him but looked at each other with slight worry as they all walked to the market place. As they did, the oldest and the youngest had an idea for their investigation.

" Hey, guys," Leo called out to the rest of their family." me and Mike are gonna find Usagi. He said that he's gonna join that championship again so we're just going to try to find him,"

" Wait, why is Mike comin' with ya, Fearless?" Raph asked, getting suspicious." I'm pretty sure dat ya want ta have a secretive an' private conva'sation wit' ya'r rabbit friend,"

" Cause I really want to explore the place, Raph!" Mike pretended to whine like he was dead serious that he was bored as hell." I won't do anything to disturb him and Usagi's little conversation! I just wanna roam around, bruh!"

Don was about to say something when their father spoke up.

" Well, alright," Splinter told them with a solemn nod." Just be careful and hurry. The championship will start soon,"

Both blue-masked brother and orange-masked brother nodded in understanding before running off while the rest went to the palace.

Hmm, that was odd. Raph thought suspiciously, watching his big brother and his little brother ran off on their own. Leo neva' brings Mike over when he wants ta have a talk wit' Usagi. Somethin' ain't right…

" Phew! That was close!" Mike said, sighing in relief.

" Too close," Leo pointed out as they kept on walking." Good acting, by the way,"

" Sure thing, bruh! Anything to get this investigation started and over!"

" Come on! We really do need to find, Usagi. Maybe he can tell us if there are some new warriors coming to join and compete in the Battle Nexus Championship,"

Mike nodded. Well, at least took them a short while to find their ronin friend. Miyamoto Usagi was in a small sushi restaurant, eating some sushi when he spotted two of his kame friends. He finished his food and paid for it before walking towards the two.

" Greetings, Leonardo-san and Michelangelo-san," Usagi greeted with a smile." You are here quite early, my friends,"

" Hey, Usagi," Leo greeted back but sounding solemn." We're here to see you early for a reason,"

" And what is that?"

" We were wondering if there were any new warriors joining the Battle Nexus Championship," Mike told him, sounding as serious as his big brother.

Usagi thought for a while before responding." Hmm, why yes, there are new warriors. There are 4 new warriors that had recently entered the competition. 2 male ninjas and 2 female kunoichi. They are at that small restaurant that sells food like those of your dimension. Why do you ask?"

" Well," Leo explained." last night, I had a nightmare that there were these ninjas who attacked me in the Daimyo's palace. At first, I thought that it was a simple dream with the warriors as illusions but soon, I got worried. What if those ninjas interfere with the Battle Nexus Championship? And what if they attack the Daimyo? So, me and Mike planned to investigate,"

" Hmm, I see. I have not met these new warriors entirely but let us make sure they will not cause any trouble for us or the Daimyo,"

The turtle brothers nodded then they followed their ronin friend to the said restaurant. There they saw four unusual warriors, eating and talking to each other in a tongue that Usagi couldn't understand but Leo and Mike could. They knew what language it was.

English from their dimension, meaning these warriors from their world, not anywhere else.

Mike was the one who found out this immediately after the female turtle-pug dog with brown turtle skin, long coal black hair, baby blue eyes and orange ninja suit with black pants said something that he loved to say to his friends and brothers;

The word 'dude'.

Leo found after his little brother pointed it out but felt like there was something familiar with 2 of the warriors so he decided that they should go and say hi. Usagi went ahead to start them off.

" Greetings to you all, my fellow warriors," he called out, attracting the attention of the four.

They finished their meal, stood up and walked towards the samurai and the 2 ninjas. The male turtle-rabbit with green fur, grey eyes, blue mask, dark blue kimono, and brown pants seemed to look like the eldest as he looked over the 3 and smiled.

" Hello there," he greeted, holding out one of his hands." My name is Miyamoto-Hamato Ichiro but you can call me Hiro,"

Leo felt like he'd seen that green paw and grey eyes before but he didn't want to be rude with silence so he shook the hand and replied.

" It's a great honor to meet you, Ichiro," he greeted back." My name is Leonardo but you can just call me Leo. This is my little brother Michelangelo or Mike and this is our friend Miyamoto Usagi or Usagi. We're ninja turtles and our friend here's a samurai rabbit,"

" Ninjas? Samurais? Cool. My dad's a samurai and my mom's a ninja so I have no idea what to be in when I grow up,"

Hiro started laughing and they all joined in. Leo faked out his laughter so it could hide his suspicions as the warrior in blue began to speak all over again.

" Anyway," Hiro started." These are my younger cousins; the female turtle here with dark green turtle skin, green eyes, scarlet ninja suit with dark brown pants, and red mask is called Hamato Naoko, the male turtle-human here with peach turtle skin, short coal black hair, chocolate brown eyes, purple kimono, grey pants, and purple mask is called Jones-Hamato Shinto, while this young female turtle-pug dog with brown turtle skin, long coal black hair, baby blue eyes, golden mask and orange ninja suit with black pants is my youngest cousin; Hamato Kaiya,"

" Hey there," Shinto greeted with a slight wave." You can call me Hint,"

" Sup, warriors," Naoko rolled her eyes and flipped her mask as if it was her hair." You can call me Nak,"

" And you can call me Iya!" Kaiya cried out in excitement as she got Mike's hand and shook it as quickly as she can." Hi there! It's great to meet you all!"

" Um…it's, uh…great to meet you too, um, Iya," Mike felt that the young ninja's enthusiasm was too much, even for him.

" It is truly an honor for us to welcome you and your cousins to the Battle Nexus, Ichiro," Usagi said with a smile." It is also an honor for you to join us for the championship for great and honorable warriors,"

" The honor is mine, Usagi," Hiro bowed." You know, our grandfather used to come to the Battle Nexus any time he could to visit the Daimyo and his son. Well, at least he used to,"

Hiro's expression suddenly turned dark as he looked down, clenching his fists and gritting his teeth.

" Why? What happened?" Leo asked, placing a hand on the young warrior's shoulder.

" He stayed here for a month to help the Daimyo defend the Battle Nexus from creatures that wanted to take over this place," Hiro coldly replied, his voice sounding very hoarse.

Hmm, the war for the safety of the Battle Nexus? Usagi thought in his mind as he listened. I wonder who is his grandfather. I was there at the battle so I must know the creature he refers to.

" After that month," the young warrior continued." I found a portal to this world and found him bleeding his life out. I tried to cry out for help but no one came. Not even the Daimyo…"

He slightly turned and glared at the 3 warriors. Leo's eyes widened when he saw the grey eyes filled with fury so he took back his hand and sighed.

" Hiro, I'm sorry for what happened to you grandfather," he told him in the most reassuring voice that he can let out.

Hiro's eyes soften then his lips curled up into a smile so toxic that it made Usagi's fur stand and it also sent a shiver down the shells of both Leo and Mike.

" But then, those events are all in the past now," the turtle-rabbit pointed out, looking up at his 3 new friends." I was 10 years old when that happened. Now, we just want is to win the Battle Nexus Championship and regain the honor of our grandfather since we found out that he had won the contest a couple of times,"

" So true," Nak agreed, nodding.

" Our parents know what happened to grandpa," Hint said." so they know where we are,"

" Yeah!" Iya twirled her axe around happily." We are so gonna win the Battle Nexus Championship!"

The four cousins laughed and happily cheered as they walked ahead out of the restaurant and onto the paths. Usagi, Leo and Mike looked at each other worriedly while they walked behind the four.

" They do seem to act quite strange," the ronin pointed out, rubbing his chin." They act as if they hide something,"

" Yeah," the ninja in blue agreed with suspicion." Honestly, Hiro and Hint kinda looks familiar for me, as if I've seen them before,"

" What do you mean, Leo?" the ninja in orange asked.

" I feel like they're 2 of the warriors that attacked me in my nightmare last night,"

" Hmm," Usagi thought." that would mean that your nightmare is true and a warning for us to be careful,"

" Wait, what about the others, dudes?" Mike wondered." What if they get hurt?"

" Hmm, you have a point there, Mike, but just, not yet," Leo told his little brother." We don't have enough proof yet so we can't prove what they're about to do. We have to keep investigating until we've found them guilty,"

Mike felt discouraged but still nodded in understanding then they all ran to catch up with the younger warriors.
