AN: OK I think it's time I unveil my Decade idea, which I've been thinking for so long. Just to let you know this Decade is an OC, just to let you all know. Also some of the worlds he will travel to are my other rider stories. So here's a sneak peek.

Disclaimer: I do not own Kamen Rider or any anime characters except my OC.

Kamen Rider Decade: A Journey through the Worlds Idea.

Kamen Rider Skull was getting near Shinji ordering him to step aside so he can kill Asami; Shinji's client.

"Shinji, move." Skull ordered while Shinji did nothing yet. Nihlus wanted to do something but he can't. Shinji went through his memories of Boss before punching Skull directly in the face.

"I will fight for my client." Shinji answered. "Even if my life is at stake…I will follow your teachings. If you yourself get in the way…then I will fight. The real you…lives on in my heart."

"That's right." Nihlus said. He looks at Shinji and Rei before looking back at Skull. "They committed and acknowledged their sins on that day. They counted it up and as retribution and in honor of you…they will fight together as partners. The two will always be together to stop the tears of this city, no matter what. And, they will get to the truth and will fight for their client as both detectives and one Rider. A fellow Rider should at least respect because deep down in their hearts, they know that the real you does while this you… is discriminating that memory!" They then heard the Death Dopant's voice.

"Impossible! Who are you, people!?" Shinji started.

"I am… No. We are..." Shinji looks back at Rei who is now smiling. "…mementos of Boss. The two of us are a single detective…and a single Kamen Rider!" Nihlus got out his Decadriver.

"And, I'm just a passing-through Kamen Rider. Remember that." Nihlus said as he got out his card and opened the Driver. Shinji and Rei then got out their Memories.

"Ikuze, Rei!"

"JOKER!"

"Hai, aibou." Rei said when she took her partner's side. Asuka, Mari, Misato, and Fu were smiling watching them.

"CYCLONE!"

"Henshin!" The three riders said. Nihlus placed his card in the buckle and closed it.

"KAMEN RIDE:…DECADE!"

Soon nine different symbols appeared and soon transformed into gray holographic figures. The gray figures surrounded Nihlus and combined into a black and white armored figure with green compound eyes and several magenta plates came out of his belt and went to his helmet. Dyeing his sides and the face of his helmet in magenta color. His eyes took emerald color and a yellow jewel between them. This was Kamen Rider Decade.

Rei placed her Cyclone Memory in her driver which soon vanished to Shinji's Driver. Shinji pushed it in along with his Joker Memory and soon pushed the two slots aside.

"CYCLONE-JOKER!"

While Shinji was turning into W, Decade went behind Rei and caught her when she collapsed. Decade dragged her to a safe place and joined his fellow Rider. The three stared at each other before charging. Decade and W were dodging and countering Skull's punches. It wasn't until W grabbed Skull and literally went through the wall with Decade in pursuit.

Outside Decade grabbed his Ride Booker and transformed into a sword. He placed a card in his Driver and closed it.

"ATTACK RIDE: SLASH!"

Decade's sword started glowing pink and two silhouettes appeared. He started slashing at Skull and down on the ground with his armor smoking. W picked him up and started punching him. He soon let go and gave him a spinning aerial kick.

"Shinji, don't you care what happens to me? Do you want to kill me again?" W soon got out the Heat Memory.

"HEAT-JOKER!"

W's right fist then became burning red and when Skull got up, W punched him in the face. When Skull got down he transformed back into Father Shijima. He looks down at his damaged GaiaMemory and attempts to plug it into himself. He did and started to transform right around the girls came out with Rei's body.

"DUMMY!"

When he transforms, the Riders sees several figures before turning into the Death Dopant. W's eye started blinking.

"I see now! The D doesn't stand for Death, it stands for Dummy!" W then got out the Trigger Memory.

"HEAT-TRIGGER!"

W got his gun out and Decade soon turned his sword into a gun. The two then started firing until the 'Death Dopant' transforms again. He now had silver armor which didn't match at all. The Riders and the girls stood surprised.

"That's his true form? Looks crappy." Asuka commented.

"I have the ability to have any talent! I lure the bigwigs' in town with their loved ones' deaths, then I become them! I was able to enjoy so many gorgeous lifestyles."

Asuka grabbed out a green slipper and hit the Dopant in the head.

"How disgusting! You three, get him!" W and Decade nodded.

"You don't need to tell us twice." Shinji said from his side. W pointed at the Dummy Dopant and both halves said.

"Saa, omae no tsumi kazoero!"

"If we did then we'll be here all day." Decade stated. The two then shot him again but before they can do anything else, they heard two mechanical voices.

"ADVENT!"

They were soon attacked by Metalgelas and Venosnaker, who appeared for a brief moment before disappearing.

"What was that!?" W asked.

"Dammit! I didn't think the Dark Riders would be here by now!" Decade commented. Soon two Riders appeared. One was clad in a black bodysuit with silver-grey armor covering his body. The chest armor was bolted on and he had blocky shoulders with a curved spike jutting from the left one. His helmet had a bolted on visor with horizontal slit and a horn in the center to mimic the appearance of a rhinoceros. Flaps of armor hung from his belt and the belt held the Rhino Advent Deck in the center. This was Kamen Rider Gai.

The other Rider was purple and his armor's theme was a cobra. He was holding a cane with a snake head. And in the center of his belt was the Snake Advent Deck. This was Kamen Rider Ohja.

"I'm guessing these Kamen Riders are the bad ones, right?" W asked.

"You have no idea."

"More Riders!?"

"Relax, old man. We were sent here to rescue you." Gai said.

"The boss only wants to use your power so be grateful." Ohja stated. The two Riders pulled out two more cards. They placed it in their Visors.

"STRIKE VENT!"

"SWORD VENT!"

Gai then got gauntlet that had a Rhino's horn while Ohja got a sword that was modeled after a Snake's tooth. W got the Metal Memory.

"HEAT-METAL!"

W pulled out his staff and Decade got out his Ride Booker in sword form while the girls got to a safe place. W took on Gai while Decade fought Ohja. W was trying hard to hit Gai but despite his heat based attacks their barely doing any damage to him.

"That tickles!" Gai commented before hitting W in the chest. W flew back and got up with his default Memories.

"CYCLONE-JOKER!"

W charged again. Decade wasn't having an easy time with Ohja either. Ohja was a trained killer so even out of his Rider form he's just as dangerous. While fighting the Dummy Dopant ran away, the two Dark Riders noticed.

"Hey, he's getting away!" Gai noted.

"That ungrateful pig!" Ohja said, agreeing with his partner. He then took out a card from his deck. "Looks like, I have to use the card the boss gave me." He then threw it at the Dummy Dopant's back and soon went in. The Dummy Dopant groaned in pain before transforming. His armor was more bulky and intimidating, he got bigger, and his hands turned to claws. The new Dummy Dopant turned around and went to Ohja's and Gai's side.

"That's better." Gai commented.

"Destroy them!" Ohja ordered and the new Dummy Dopant charged at W and Decade. This new Dopant was attacking like a monster and easily overwhelmed the two Riders. When Decade got up his Ride Booker opened and ejected three cards. He caught them and when he looked at them, the cards now had color with W's face and themes. Rei noticed.

"Is that the trump card?" Decade nodded.

"Shinji, Rei, this might tickle a bit." W stood confused and Decade placed one of the golden cards in his belt and closed it.

"FINAL FORM RIDE: D-D-DOUBLE (W)!"

Decade placed his fingers deep into the line that separated W. He then literally split W apart. The halves soon materialized their own halves turning them into Kamen Rider CycloneCyclone and Kamen Rider JokerJoker. Each of them also had two of the same Memories in their Drivers.

"CYCLONE-CYCLONE!"

Kamen Rider CycloneCyclone looked at JokerJoker.

"Shinji?"

"JOKER-JOKER!"

"Rei!" Everyone was surprised when they saw this transformation.

"He…split them apart." Fu commented.

The two halves looked at the new Dopant with Gai and Ohja.

"So what? You two don't seem that tough." Ohja said.

"Let's prove him wrong." Decade commented as he charged.

"Ikuze, Rei."

"Hai, Shinji." CycloneCyclone and JokerJoker charged along with Decade. Gai tried hitting CycloneCyclone but she was too agile. She then punched Gai in the chest before placing one of her Memories into the Maximum Drive slot.

"CYCLONE! MAXIMUM DRIVE!"

CycloneCyclone's right foot was then consumed by a miniature green tornado.

"RIDER KICK!"

She did a spinning kick to the helmet. When she did, he literally flew a few inches away before landing head first onto a grave stone.

JokerJoker was countering Ohja's punches and hitting him back. Ohja got out his saber and to his surprise his saber was blocked by his arm. JokerJoker placed one of his Memories in the slot as well.

"JOKER! MAXIMUM DRIVE!"

His fist soon became consumed by a purple flame.

"RIDER PUNCH!"

He then punched Ohja in the chest before he crashed into Gai, who just got up. The two halves looked at each and it wasn't hard to tell they were smiling at each other.

"Hey guys! A little help here!" Decade said while fighting the new Dummy Dopant. The two halves joined in and fought as well. While fighting Decade took out another gold card and placed it in his belt before closing it.

"FINAL ATTACK RIDE: D-D-DOUBLE (W)!"

"Ikuze!" Decade said before he jumped in the air. The others soon followed. Decade aimed with his right foot while CycloneCyclone and JokerJoker aimed with both of their feet. When they hit him there was a massive explosion. Decade and W, who just merged back, got out and Gai and Ohja got up.

"This isn't good. Let's get out of here! Dark Decade is gonna kill us for this." Gai said before he summoned a Gray Mirror. Ohja just growled before he joined his fellow Rider. When they were gone W and Decade started each other.

Shinji, Rei, and Nihlus just shook hands with smiles all around.

"Remember what I told you?" Nihlus asked.

"Hai, keep an eye out for Dark Riders…and the Rider War will begin soon." Nihlus nodded before he and Fu left, he gave Shinji one of his cards.

"It's yours." was all Nihlus said before he and Fu walked away. Shinji and the others looked at it before seeing the card had Kamen Rider Skull's picture on it. They then saw Skull, he took his hat off, and his helmet dematerialized leaving a familiar face.

"Boss!" Shinji said.

"Another Kamen Rider Skull from another world?" Rei questioned. Boss looked at them before looking at Shinji.

"I don't know who you are, boy. But, there's something I like about you. The way you wear your hat is proof you're a full man." Shinji was speechless before Boss placed his hat back on. "My name is Kamen Rider Skull. Let's meet again, somewhere in this world." Was all he said before he got on his bike and drove off in a Gray Mirror. Rei noticed something on Shinji.

"Shinji, are you crying?" Shinji shook his head.

"Hard-boiled guys don't cry. But, he said he likes the way I wear my hat." Shinji said before he took a deep breath while making sure he didn't have any tears.

AN: There's my Decade idea. If you're wondering, Fu is the one from the Naruto/Kabuto world. You know, Fu is the Jinchuriki of Chromei, the Seven-tails. I won't tell you how she ended up traveling with Nihlus; you'll have to read the full story soon. Nihlus and Fu are the pairing for this story. Also thank you all for cheering me up. I feel better now. So far is my list of Rider Worlds:
