Location : Ruined Konoha
A visibly aged Naruto wearing bat-like suit with trench coat, black scarf and sand goggles with a familiar staff on his back could be seen coming out from a bunker as he stared at the ravaged village with an Omega symbol on the ground. He looked at the scorching ground as a joker card flying passed him.
Scene shifted
Now, Naruto and an army of the survival of the ravaged and terraformed world gathered at the once Konoha's Academy as they waiting for another army of the survivors. When their leader arrived with a box, Naruto walked towards him.
"Do you have it?" he asked with his deep voice to the man who was a Kumo-nin.
"Yeah I do. The last piece of Chakra Fruit that I managed to steal from Izumi's Castle." he replied as he opened the box only for Naruto to find the inside of the box is just a note instead of the fruit. "I'm sorry."
The Kumo-nin's army, the Regime, began to surround Naruto's army, the Insurgency, and aimed their weapon at the shinobi's throat as they raised their hands including Naruto. Immediately, they all were executed, much to Naruto's dismay who immediately launched several kunai projectiles at the Kumo-nin, killing him as he began a killing spree.
He used the broken Sandaime Hokage's staff and swung it at several Regime's shinobi, then knocked one of them to the ground as the remaining Insurgency soldier fighting against Regime soldier. Seeing one of the Insurgency was murdered in front of his eyes, Naruto's blood boiled as he began to throw several kunai at Regime's shinobi that went through their chest and forehead as dozens of humanoid insect creatures arrived at the area and murdered the Insurgencies.
A Regime shinobi managed to hit in the face followed by two Regimes that grabbed his arms with one of them used the broken staff to hit Naruto's abdomen. He then stomped the Regime's knee and swung the staff at the Regime who's grabbing his arm.
But due to his old age, he's getting tired easily and slower, making several Regimes kick and punch him but nevertheless he managed to knocked them out and killed several of them before he was pinned by five Regimes who's punching and kicking him in the face with one of them was unfortunately died due to Naruto snap his neck before he was knocked out by a humanoid insect with wings creature who witnessed the Regimes' struggle to take him down.
When the 50 years old Naruto woke up, he found himself chained to the ceiling with four survivors. They then watched in horror as a beautiful pale-skinned woman with white long wavy hair and purple rippled eyes with one crimson rippled eyes and six tomoes on forehead appeared in front of them as the Regime's shinobi knelt before their Queen.
Among those Regime's shinobi that kneeling before their Queen were Obito, Minato, Kushina, Jiraiya, Tsunade, Orochimaru and Kakashi. All of them were corrupted and have glowing purple eyes with pulsating golden veins.
As she walking to them, Izumi swiftly murdered the survivors with chakra wave that coming out from her eyes. She then stared at the terrifying Naruto and smirked as she pulled the cowl, chuckling at the terrifying elder man.
"If only you accept my offer, you and those pitiful humans won't be murdered." said Izumi to Naruto as she placed her hand on his chest.
Hearing the heart beat of her arch-enemy who she once confessed her love to him and offered him to rule the world alongside her, Izumi sneered at him before tore his heart out of his chest.
Naruto woke up from his sleep and found an unstable and distorted blue portal of energy beside him. From it, he saw a man cladded in red armour with cloak appeared as his mask opened.
"Naruto, listen to me now! It is you! You are the key!" screamed the man as several rotten arms with long claws grabbed his arms, burning the armour and made him screamed. "ARGH! Am I too soon?"
Naruto who's confused at what he is seeing right now unable to say anything as the man who stared at him was horrified.
"No! I'm too soon! Don't do it Naruto! Don't merge with it! Find me, Naruto, you have to find me!!" the mysterious time traveller said as he was being dragged by the arms.
Once again Naruto woke up from his sleep. He looked around and confused at what just happened. Was it a dream or... something else? He looked at the clock and get off from the bed before went to the bathroom to wash his face.
After having a nice shower, Naruto walked downstairs and saw Tobirama preparing breakfast for him while wearing a blue apron with the words of I AM THE BEST CHEF IN THE WORLD and KISS MY FOOD written on it. Naruto couldn't hide his smirk and unable to deny that he's happy Tobirama wearing the apron that he gave on Tobirama's 80th birthday.
"Morning Naruto."
"Morning jiji." said Naruto as he sat down while Tobirama arched his eyebrow.
"Something happened? Do you still have the nightmare?" asked Tobirama with worry tone to the boy who he saw as his grandson and legacy.
"I had a dream... A weird dream." said Naruto to Tobirama.
"How weird?"
"I saw myself as an older man, leading an army. We were waiting another survivors at the ruined Konoha. I was asking one of the survivors about a fruit... Turns out it was a ruse and the survivors kill my army and knocked me out. When I woke up, I saw this woman with weird eyes."
Again Tobirama asked, "How weird?"
"Purple rippled eyes. Apparently there's another rippled eyes but looks like Sharingan. So this woman killed me and then I woke up and I saw a mysterious man in red armour warning me about something before he disappeared just like that." said Naruto to Tobirama who didn't say anything and looked at his legacy with the stoic face but inside he was shocked.
'Rinnegan...' thought Tobirama to himself as he sat down and poured the green tea to Naruto. "It just a dream. You still have some time to train."
"I'm planning to figure out my summoning animal." said Naruto to Tobirama who seems to be surprised. "If you don't mind, can you help me?"
"I wish I can but I don't have any summoning contract although I can teach you few of my arsenal. But from what I heard, if you tried to summon, you will be summoned to your suitable summoning animal's place instead. Try it." said Tobirama to Naruto. "I'll teach you the hand seals."
After having breakfast and playing shogi match for two hours, Tobirama instructed Naruto the hand seals which he did and immediately disappeared.
Location : Realm of DragonsNaruto then found himself in a location that he felt familiar as he observing the beautiful environment such as floating waterfalls and islands with trees that have glowing green apple-like fruit. As he enjoying the view, he sensed someone's watching him.
When he turned around, he saw a huge crimson dragon with golden eyes staring at him like how a predator staring at its prey.
"WHO ARE YOU?! WHY ARE YOU HERE?! HOW DID YOU GET HERE! ANSWER ME OR I WILL EAT YOU!" said the dragon to Naruto as he roared loudly, making more dragons to come to his location and surrounded Naruto. "Answer me or prepare to die."
"My name is Naruto. I was trying to figure out my summoning animal since I don't have the contract or the scroll. The hand seals that my grandfather taught me brought me here."
"Lies! Die-"
"Naga wait!"
Before the red dragon or Naga could crush Naruto, a beautiful black dragon with a pair of angelic metallic golden-silver wings,two horns, two violet eyes and white glowing cracking mark across her body sniffing at Naruto, much to the latter's dismay.
"His scent reminds me of someone."said the dragon to Naga.
"Who, Kasturi?" Naga asked to Kasturi.
"Yoriichi... The King who vanquished the Greatest Calamity.. The first swordsman of the world and the creator of Breath of Sun Style." said Kasturi to Naga. "Boy, do you have any relationship to Yoriichi."
"I don't but my grandfather used to tell me a story of a king who saved the world from this Greatest Calamity." said Naruto to Kasturi.
Another dragon, who has silver metallic body with black 死 on his arms and a scar across his golden eye, wearing eye patch and have skeletal wings asked him, "Who is this your grandfather, human."
"Senju Tobirama."
A wood dragon said, "By any chance does he has any relationship to Senju Hashirama?"
"Yes, he is the younger brother of Hashirama-sama." replied Naruto to the wood dragon who gasped while every dragons began to whisper.
"It's been a while since we have a summoner. My name is Chaos and the wood dragon is Kayu. You remind us of Tsugikuni Yoriichi." said the skeletal dragon to Naruto. "Before he died, he told us that one day, a child will save the world from the descendant of Greatest Calamity."
"I'm not interested with some kind of ancient prophecy. I'm here to find out what is my summoning partner, nothing more, nothing less." said Naruto to the dragons.
"Very well then."
Naga stabbed Naruto's bicep with his claw, causing a dragonic tattoo-like mark appeared on it.
"Now, write your name and sign on the contract with your blood." said Naga to Naruto as Kasturi summoned a scroll and opened it with a single tap, allowing Naruto to see the name of the summoners.
From Tsugikuni Yoriichi to an Otsūsuki whose name unable to read due to the language to Namikaze Arashi and finally Senju Hashirama. Naruto bit his thumb and wrote his name,
Senju Naruto.
"Senju? But you do not possesses the blood of Senju." said Naga to Naruto who smirked.
"I know but I am the apprentice of Senju Tobirama."
The dragons looked at Naruto and accepted him as their new summoner. They then witnessed him disappeared from their realm, possibly heading to human realm.
Or so what they thought.
Once Naruto gone from the Realm of Dragons, he appeared at a cave that made him arched his eyebrow. He looked around and saw a scroll on the ground. Picking it up and opened it, he saw a bat design on the scroll.
Upon touching it, he felt his thumb being stabbed by something sharp and in few seconds, his name and his signature appeared on the scroll even though he didn't write it yet.
Before he could do anything, he returned back to the Senju training field and saw Tobirama.
"How is it?" asked Tobirama to Naruto and all his legacy replied was showing two scrolls. "Two summoning animals? How is this possible..."
"I don't know but I'll talk to the Dragons about this."
"Dragon?"
Naruto replied, "I'm not sure the other one but I think it might be belongs to the Bat."
Knock Knock!!
Kushina opened the door and saw her tired husband and smiled. She let him enter the house and went to the kitchen to prepare a cup of green tea for him.
"What's wrong Mina-kun, you seems to be more tired than usual." said Kushina to Minato as she served the tea to him, earning a thank you him.
"Yeah, the meeting and the upcoming Chūnin Exams. We received letters from Suna, Yami, Kiri, Iwa, Kumo and Hoshi." said Minato to Kushina. "Ame, Kusa and a new village call Oto will participate too."
"Iwa, Kumo and Hoshi? I don't know Mina-kun but I felt something's wrong with them." said Kushina to Minato.
"Yeah, Tobirama-sama and Hiruzen-sama told me the same thing too. They believe that Iwa, Kumo and Hoshi have something that they hide since it's been decades since they participate the Chūnin Exams. I fear that... Another Great Shinobi War will happen."
Kushina didn't say anything and understood that Minato is afraid of another Great Shinobi War. Not because of his enemies but because of his children who he want to spar them from the horrifying war. She remembered how terrifying it was when she witnessed her friends were murdered in front of her eyes by her enemies.
That's why she decided to get back to her prime shape after losing to Zabuza. She looked at the tired Minato and said,
"Mina-kun, can we train together? You know after we have the kids, I stop training because I want to spend my time to the family. You know when I told you that my days of shinobi are over when I gave birth to our children." said Kushina to Minato who smiled.
"Let's begin the training tomorrow."
Night later
"I'm heading to sleep now. Goodnight, old man." said Naruto to Tobirama who wished him a peaceful sleep.
He went to his room after having hours of training to perfect Gōjo Kibaku Fuda as well as mastering several of his Suiton jutsu.
As he laid on his bed, he kept thinking about the mysterious man in red armour warning him about merging with it. What is this it? And then that mysterious woman with those eyes. He swore he knew those eyes but unable to tell the name and tried to remember it but to no avail.
He wondered was it a dream? He felt like it was real. The woman's hand on his chest, the pain of his heart being torn out. And then there's an Omega symbol on the ground. The flying creatures. He felt very familiar but unable to figure it out.
He then fell asleep.
Knightmare/Future
"It is a suicide. Eating Chakra Fruit to end her reign and Kaguya and Ukina once and for all." said the mysterious man cladded in red armour with yellow lightning symbol on the chest to Naruto.
Naruto replied as he stared at the picture of him smiling with Mizuki and said, "38 years of living in this hellish world... The Knightmare... It has to end now. It's all my fault."
Naruto placed the picture inside a box that has the happuri of Nidaime Hokage along with a diamond necklace and placed it on table as he wore his cowl and said, "That is why I trust you with this backup plan. I afraid that the plan to eat the fruit will fail and all of us will be executed. So I want you to proceed with the Plan B."
"Plan B?"
"I want you to travel back to the past to warn me about the Merge. Perhaps there's a chance for you to prevent me from the Merge as well." said the aged Dark Knight to the long black haired man with blue eyes. "Can you do it, Flash?"
"But I never travel back to past. I am not fast enough to do it." said Flash to the Dark Knight.
"V will help you. With her calculation and your Cosmic Treadmill, you can travel back to past to prevent this Knightmare." said the Dark Knight to Flash. "Can you do it, Flash?"
"You have my words. I will prevent this Knightmare." said Flash to the Dark Knight as they left the meeting room and went to a room with a treadmill while a woman with long black hair and dark eyes wearing glasses could be seen inside the room. "I guess this is the goodbye."
"Farewell Mikhail. You are a good friend." said the Dark Knight as the Flash went to the treadmill as the mask went down to cover his face.
V then said, "With my calculation that I uploaded into the treadmill, you will be able to travel back in time. You might have to run five times faster than you capable of."
"You mean I have to break my limit? What will happen if I accidentally travel back too far?"
"The outcome will always be same. This timeline will gone." said V to the Flash. "You however I don't know what will happen since you're the one who will change the past."
"I might be erased from the existence since I will change the past but what if this timeline is still exist?" asked Flash to V but Dark Knight replied it for him.
"It won't because you will erase it. Godspeed, Flash." said the Dark Knight to Flash.
"Farewell Batman." said Flash as he gave a sharp nod to V.
V nodded her head as the Flash took a deep breath and began to use his superspeed to run at the treadmill, producing unstable bluish white lightning as he running faster than he ever was.
And then he disappeared from V and Dark Knight's sight, heading to the past to change the timeline.
