AN: Before I begin, let me say this to start with my Kabuto readers, I ALREADY found someone to be Gatack. I won't mention who but the only hint I will give is that this person is already in the two chapters so far. You can still guess on TheBee, the Hoppers, or Dark Kabuto but Gatack I already chosen. Now then time for me to introduce my new Decade. I used an OC because Tsukasa is an a**hole most of the time. His name is Nihlus Kryis. If there's anything off about him let me know. Also pairing is NihlusxFu. Now, ShowTime!

Disclaimer: I do not own Kamen Rider or any Animes or Cartoons. I only own Nihlus and other OCs if mentioned.

Prologue: The Journey Begins

Fu finds herself on a battlefield and sees a huge battle occurring. She recognizes Kabuto, Drake,and Sasword as they were fighting alongside other armored figures who she presumed were Riders. She sees explosions and people dying on both sides. She was shocked by all the destruction and chaos even when she saw her friends falling in battle. After multiple explosions, she sees two figures.

She looks to her left and sees a figure with green insect eyes, has a white buckle with insignias and red dot in the center, and was surrounded by a pink aura.

"Decade." She said.

She soon looks to her right and saw a similar figure. But this one had blue eyes, a black buckle with a purple dot in the center, and was covered by a dark aura.

"Dark Decade." She said again.

Both Decades looked at each other and drew their swords. The two ran through the battlefield of their fallen comrades only for the blades to meet. They clashed causing a huge light that woke Fu up.

Fu got up sweating and looked to see that Ayano was still asleep and the Sasword Zecter deactivated. She took deep breaths and was surprised Nanabi didn't say anything.

"What the hell was that?" Fu asked herself.

(Play Journey Through the Decade by Gackt)

{Kamen Rider Decade. He has been given the power of a destroyer to destroy one.} As the song starts the scene focuses on Decade, who just transformed, standing in a white room filled with filming clips.

{Miageru hoshi sorezore no rekishi ga kagayaite} Fu covers Nihlus's eyes until she lets go. His eye is zoomed in and is soon replaced with the camera, his camera, and later his upgraded Decadriver which includes all 14 Heisei Riders including himself. His Machine Decader is shown parked in front of a pile of smoking rubble. In the white room Nihlus grabs one of the cubes and faces the camera.

{Seiza no you sen de musubu shunkan hajimaru Legend} The scene changes to a worn down warehouse with all Riders sitting but one at a time. Fu grabs a bottle and looks at it. Nihlus looks back. Yugi slumps his back against his TryChaser 2000 as the silhouettes of the other Riders appeared one by one. Fu throws the bottle down on the floor.

{Oorora (aurora) yurameku jikuu koete. Tobikomu meisou suru Parallel world} On one side the Dark Riders charge while on the other the Riders of Good did the same. When the bottle shatters, Nihlus looks as though he was about to collapse but not before his face changing into each of the Riders' helmets. Back at the warehouse all 14 riders were lined up doing their signature poses and with Decade in the center but behind him was Fu.

{On the road dare mo tabi no tochuu. Hontou no jibun jishin deau tame.} All 14 Riders were in a circle and were fending off the Dark Riders as they were being surrounded by them. Nihlus is then shown on his bike getting his helmet on and Fu was riding passenger. Fu grabs on to him tightly. Next, Decade shows off his fighting skills especially with the Attack Ride: Slash card. Soon back to the Riders, everyone was doing their best trying to watch each other's back while against the Dark Riders.

{Atarashii yoake e to tsuzuku michi ni kawaru no darou.} Nihlus sits alone exhausted and with tears rolling down his face until Fu was in front of him with his camera in one hand and offering the other to help him up. We soon see Yugi riding with Nihlus and Fu on their respective bikes. Back on the battle, Blade was having trouble with Glaive until Decade shows up and pushed Glaive away. Ryuga was about to use his Strike Vent on Decade until Ryuki used his first which saved Decade.

{Mokugekise yo Journey through the Decade.} The Riders were helping each other trying to take down their respective foe. Soon Fu is seen with a smile in Decade's mind. But Decade focuses on the battle and helping his comrades. Decade was soon on his bike driving out of a Gray Mirror with pictures of the other 13 Riders in it and they circled the logo.

(In another world)

*CLICK*

Was the sound being made from a pink camera in front of the local park's river. Holding the camera was a man in his late teens, he had pale skin, brown eyes, and messy black hair. He also was wearing a black hoodie, a white shirt, jeans, and sneakers. His name was Nihlus Kyric.

There's not much known about him even to him. Nihlus was an orphan and his name was the only thing that he remembered. He lived on his own when he was old enough to leave. He was also a fan of anime and other things, especially Kamen Rider. Nihlus also loved taking pictures with his lucky camera but the pictures were…not so great. And, even though he was bullied in school he didn't let that stop him from living his life. Nihlus was about to leave the park until he bumped into a group of people.

"Can I help you?" Nihlus asked. The group took out distorted pictures and Nihlus immediately understood what that meant. He was working at the Hitachi Studio to make a living but…he was surprised he wasn't fired yet. He often related his situation with Tsukasa from the Decade series.

"What the hell is this!?" the leader of the group asked. "We paid for good photos and all we get is this crap!"

"I'm sorry but I really can't do much about it."

"Well, for one you can give us our money back."

"Why not talk to my boss about it then?"

"I rather talk to you first." Nihlus began taking steps back.

"Now then, I'm sure there's no need for violence…" Nihlus began walking backwards slowly but the group sees what he's doing.

"Get him!" The leader ordered and soon Nihlus was running for his life. After a few minutes of running and hiding through the city Nihlus sighed as he was in the clear. Nihlus soon went to the studio to meet with his boss, Hino Hitachi. He was middle-aged, gray haired, and wore glasses. When he went in he sees Hino with an angry face and Nihlus was prepared for another lecture.

"Nihlus, I heard that another group went after you regarding your pictures." Hino said gently. Hino liked Nihlus's pictures saying they were creative and unique and to Nihlus, he was like the father he never had.

"I know, I don't know what the problem is though, I try really hard but it just doesn't seem good, no matter how I adjust my camera." Nihlus said while looking down. Hino placed a hand on Nihlus's shoulder.

"Nihlus, you're a good kid but you really need to be better at this. I even got a whole crowd this morning about your photos this morning."

"I understand, Mr. Hitachi." Nihlus stated.

(Later on in the day)

Nihlus was walking around the city and was looking for a place to relax. As he made his way towards the park but as he did everything soon turned night to him. He looked around and was all alone.

"Yo, New Decade." Nihlus turns around and recognizes the man behind him.

"You're Tsukasa Kadoya from the Decade series." Tsukasa nodded.

"Well, a world in which the Riders are a TV series, huh? At least you're well informed and I don't have to refresh your memory that much."

"Huh?"

"You saw my journey, correct?" Nihlus nodded.

"What if I was to say that you will have one as well?"

"Hmm?" Tsukasa sighed and shook his head.

"Now, I know how Wataru feels." Nihlus just stood confused while waiting for an answer. "I'll make it brief." Soon around him and Nihlus were not nine but thirteen Earths around them. Nihlus's eyes widened as he recognized this.

"Are…Are they falling apart?" Tsukasa shook his head.

"Then what?" Tsukasa snapped his fingers and the two find themselves in a field. Tsukasa pointed behind Nihlus.

"Him." Nihlus turned and towards his surprise he sees Kamen Rider Decade but his armor is black and yellow, and his eyes were blue. "Dark Decade." And behind Dark Decade was every Dark Rider that Nihlus has ever seen from the Kamen Rider Series. "The Dark Riders are making a move, trying to conquer each world, each story, and turning them into their own. And soon, this one."

"Can't you and the others do something about this?" Tsukasa shook his head again while they were back in the park.

"This Rider Universe is…special. So much that I and the other Riders have no jurisdiction here. We have own universe to look after just like the ones in this universe. But that doesn't mean we can point you in the right direction."

"Why are you telling me this?" Tsukasa gave a light laugh.

"Now, I know how Wataru felt when he met me. It's because…you might not remember but…you will unite the Riders of this universe against Dark Decade and his Riders if not then the worlds are submitted in darkness and Dark Decade will trigger a new Rider War. So another good thing would be to warn them as well. Defeat Dark Decade as soon you can otherwise…a Rider War will occur and no miracle will come out of it." Tsukasa said coldly. Nihlus took all this information in slowly.

"Why me?" Nihlus asked. Tsukasa smiled.

"It's because…you are this universe's version of me. You are this universe's Decade. Try to find your Driver and cards, they're both upgraded." Tsukasa said before a white light blinded Nihlus and he found himself back in broad daylight.

"Did that really happen? Am I really Decade?" Nihlus asked himself. He also thought if he was Decade then was it possible that he lost his memories like Tsukasa. Before he could walk to a bench, a Gray Mirror appeared and soon dropped off several monsters. Nihlus ran as fast as he could and remembered that he needed his Driver and cards. "Tsukasa could've at least given a hint to where they are." Nihlus said to himself. He soon stopped as he saw a black hooded and coated man. He was ordering the Imagin around and killing innocents.

"Find them, we can't let Decade escape here." Nihlus tried to sneak past them and continued running as he was in the clear. Unfortunately, the cloaked man grabbed him by the throat. "So you're this world's Rider? I thought you would at least give me some challenge. No matter." He soon through Nihlus into a pile of rubble and the man walked up to him. A belt materialized around his waist and he pulled out a golden pass. "Henshin!" he soon swiped the pass.

"GAOH FORM!"

Nihlus watched the man being replaced with a brown Den-O's Plat Form and armor was being added to it. When it was done Nihlus recognizes him as Kamen Rider Gaoh, a Dark Rider. Nihlus attempted to run again but Gaoh soon cornered him in an alley.

"Your journey ended before it began." Gaoh stated as he drew out his sword. Nihlus back himself to a wall until he looked down at the pile of garbage he was on. Nihlus picked it up and sees the Decadriver only with the insignias of the Neo-Heisei Riders as well and the Ride Booker. Nihlus quickly placed on the Driver, placed the Ride Booker on, and pulled out the Decade card. Nihlus stood up as he opened the Driver.

"Actually, it just began. Henshin!" Nihlus placed the card in and quickly closed it.

"KAMEN RIDE: DECADE!"

Then the Rider symbols appeared and turned into armor silhouettes. They merged with him and was now donned in white and black armor with a black X across his chest. Nine red plates emerged from the Driver and went in his head. When they did they became red but turned the black parts of his armor, other than his chest, turned magenta and a yellow light appeared in the center bar. This was Kamen Rider Decade.

"Dammit! Doesn't matter I can finish you off now!" Gaoh attempted to slash but Decade easily dodged and transformed his Ride Booker into a sword. He countered Gaoh's hit. Decade kicked Gaoh into the wall. Decade drew a card from the book.

"I know they're only a one time usage right now but…Henshin!" Decade placed the card in the Driver and closed it.

"KAMEN RIDE: DEN-O!"

Gaoh watched as Decade transformed into his sworn enemy, Kamen Rider Den-O SF. D-Den-O SF took out his sword and started attacking. To Gaoh's surprise, he was almost fighting as the real Den-O. D-Den-O soon gave him a slash across the chest. The two Riders were soon led to the middle of the street. D-Den-O kicked Gaoh and attempted to run but was stopped when another hooded figure appeared.

"Let me take care of this Gaoh, you need to report to Dark Decade." Gaoh growled before leaving. The hooded figure brought a purple deck with a cobra emblem. He placed it out and a belt formed. "Henshin!" He placed it in and three armor silhouettes merged over him. He had a black bodysuit, purple armor, and was themed after a snake.

"Kamen Rider Ohja." D-Den-O replied before his Driver ejected the Den-O card which was now grey. "Let's fight on fair terms, now." Decade said as he replaced the Den-O card with Ryuki. He placed the card in.

"KAMEN RIDE: RYUKI!"

Three armor silhouettes appeared until Ryuki took Decade's place. Ohja only moved his neck.

"Good, all the more reason to kill you." Ohja said as he placed a card in his Visor.

"SWORD VENT!"

Ohja and D-Ryuki were engaged in a sword fight. D-Ryuki placed a card in his belt.

"ATTACK RIDE: STRIKE VENT!"

D-Ryuki got the gauntlet and fired at Ohja. He turned back into Decade before using the explosion as an opportunity to leave. Decade arrived at the studio and sees Tsukasa at the entrance.

"Not bad." Tsukasa stated.

"What are you doing here?" Decade asked.

"One, I came to drop this off…" Tsukasa soon revealed the Machine Decader in the garage. "Two, to let you know you can use the studio to travel. And, three, I'm going to distract them while you get out of here."

"I thought you said you have no jurisdiction here."

"I know but I said that I'm going to point you in the right direction. Think of it as that. After you're gone, I'm gone." Tsukasa got his own Decadriver out. "Watch how a pro does this." Tsukasa placed it on and got his Decade card. "Henshin!" He placed it in and quickly closed it.

"KAMEN RIDE: DECADE!"

Decade watched as Tsukasa transformed into another version of him. Decade soon ejected his card out and his belt leaving only Nihlus.

"There you are!" Ohja said.

"Nihlus, go, I'll take him." Nihlus nodded and went in before Decade charged at Ohja.

At the studio, Nihlus sees Mr. Hitachi going through the news. Hino looked at Nihlus with a neutral face.

"You're back, that man, Tsukasa, told me everything." Hino explained.

"You're not surprised?" Nihlus asked.

"Well, considering what's going on outside, a man telling me about what you're supposed to do and how is the least of my worries. But if you can save this world, just tell me what I can do to help." Nihlus smiled.

"Thanks, Mr. Hitachi." Nihlus soon got to the chains holding it and let them down. Soon a background image appeared and it showed a village on one side and on the other was a man pointing at the sun. Nihlus recognizes the village from the anime, Naruto. It was Konoha. Nihlus went outside to see his clothes changed and that the building was in the village.

"This is…Kabuto's world."

(Elsewhere)

Souji, Shiro, Ayano, and Fu were making their way towards Konoha to confirm their suspicions of what's going to happen during the chunin exams. The Zecters stopped them as they looked around the area.

"We got company!" The Kabuto Zecter said. Behind them was a group of Worms.

"Fu, get somewhere safe." Souji said. Fu nodded and left. "Minna, ikuze." Everybody got their Rider Equipment out and with their Zecters in position.

"Henshin!"

"HENSHIN!" Everybody transformed into their respective Riders. They also needed to finish this quick since this was a big group.

"Cast Off!"

"CAST OFF!" Their armor pieces were sent flying and the three got ready.

"CHANGE BEETLE!"

"CHANGE DRAGONFLY!"

"CHANGE SCORPION!"

The three Riders looked at each other before charging into the group of Worms.
