Toa Solaric: Here is something that I hope to make even though the Heisei Era end and Reiwa started. I don't own Kamen Rider or Nier: Automata as I'm writing this for fun.
Kamen Rider Nexus-Automata Ruined World
Inside what looks like a ruined building, two people were resting on what looks like a large makeshift bed. One of them is a young man around the age of 18 with short black hair and honey-gold eyes. He wore a red shirt, black jacket, blue jeans, and brown shoes. This is Isamu Shinomiya.
Sleeping next to him was a young girl around the age 16 with light, brown hair that tied in a ponytail and identical color eyes. She wears what looks like a high school uniform which black shirt with white collars and red tie, black pants, and combat boots. This is Lora Shinomiya.
"Can't sleep, Lora?" Isamu asked.
"You know me, Isamu-nii." Lora replied. "It still sad that we have to leave the village when those androids been nice to us…"
It still shook them hard for them after learning what happens from the androids about what happens when they were sleeping in the capsules for a very long time.
"I know, but we cannot be never too careful about what happens if the YoRHa found out about us and harmed the village to get to us. Though it might feel nice to be treated due to their program to served humanity… but we aren't their creators. This isn't the world that we once remember." Isamu said, quietly.
"Do you think that we will find anyone else like us out there?" Lora asked.
"Maybe… but we cannot get our hopes up too high, Lora." Isamu answered. "After all, we were the only ones who were in the capsules."
It still on Isamu's mind to who is responsible for putting him and his sister Lora into the sleeping capsules and for what purpose. But the only clue is the four strange cards and Nexus Ring for them.
"I know…" Lora responds, "Anyway, let's try to get some sleep."
"Yeah." Isamu said before he tried to sleep.
In an unknown location, a black hooded figure is walking through the woods before stumbled upon a large crystal.
"So this is where have you been after the battle trapped you here for eons?" The black hooded figure remarked before he raising his hand as dark energy like orb gathering around his hand. "Now come back and elimination what is left behind by humanity…"
He soon fired the dark orb of energy at the large crystal before it glowing intense red and shatters immediately.
It wasn't long until the black hooded figure spotted a figure moving after the crystal shattered. It was a marine like humanoid with dark blue tunic and holding a forked spear in hand.
"You have been sealed away for a really long time after the battle with the Riders, El of Water." The black hooded figure spoked, approaching the marine like humanoid. "I would like your assistance in something of mine—"
The El of Water tried to swing his forked spear at the black hooded figure who dodge and placed more dark energy into the El of Water, whose eyes soon glowing intensely red.
"That wasn't very polite when tried to stab your master." The black hooded figure spoke with a cruel smirk. "Now let's try this once again…"
The black hooded figure soon watched El Lord of Water soon stop the attack and kneed before his presence.
"That is much more like it," the black figure said with a smirk under the cloak. "Now go and fight Nexus…" he ordered.
With that command, El of Water soon vanished into thin air and the black hooded figure was left behind in the process.
Soon Isamu suddenly woke up to the sound of lighting and looked out of the old building to see that it was raining.
"It wasn't storming like before…" Isamu muttered.
He soon noticed something giving a brief glowing on the table. It was none other than the Nexus Ring. It was a white handheld device with a green halo ring on the top with blue crystal and two blue and silver like wings attached to the bottom of the halo-like ring.
Isamu's eyes widen in shock as he knows what this means before he quietly took the Nexus Ring, sneaking out of the room while Lora is still asleep. Isamu soon looks around the building while following the glow on the Nexus Ring before the device giving off a more intense glow.
Suddenly Isamu hears a loud grunt sound and turned around to see the El Lord of Water tried to stab him with his forked spear. But Isamu managed to move out of the way in time to dodge the blow for his heart and giving a clear distance from the El of Water.
"So you were the one who caused the rain… Don't you know that is going to be difficult for us to travel without an umbrella now?" Isamu remarked.
"There is no future for you or this fallen world..." El of Water spoke with a low growl.
Isamu soon reached to something in his pocket and draw out a card from his pocket.
"Kuuga-san!" Isamu shouts before placing the Rider Card into the Nexus Ring.
KAMEN RIDER KUUGA!
Appearing on his right is none other than Kamen Rider Kuuga.
"Ichigo-san!" Isamu soon placed the next Rider Card into the Nexus Ring.
KAMEN RIDER ICHIGO!
On his left side was none other than Kamen Rider Ichigo.
"Please lend us your strength! Henshin!" Isamu said before raising the hand with Nexus Ring into the air with Kuuga and Ichigo at the same time.
NEXUS FUSION!
Soon Isamu is glowing in silver white color with Kuuga glowing red and Ichigo glowing light green before they merged with Isamu.
NEXUS: ANCIENT LEGEND!
The bright light faded to reveal a new armored figure in the presence. He dressed in what looks like a black bodysuit with white lines running along the sides. His chest has red and green chest armor that resembled muscle with a blue crystal glowing in the middle of the chest. On his shoulder are red shoulder guards with silver lines on the bottom. There is black and green gauntlet attached to his hands. Attaching to his waist was an unusual silver belt that had multiple buttons on the side, but the center resembled a wheel. There is also something resembled a silver booklet device that attached to his right side. There are gold anklets around his legs and attached to his feet are silver boots. His helmet is green on the upper part and black on the bottom part, with large red compound eyes, silver mouth piece, and two golden horns with a blue crystal attached to his forehead.
This is Kamen Rider Nexus Ancient Legend Form!
Nexus soon charged at El of Water with his fist in his hand to punch the El Lord, who dodged the blow and knocked him back with his forked staff.
Sending him crashing against a tree while El of Water walking slowly toward him. But Nexus managed to get back up and snapped the branch of the tree.
"If it a fight with a weapon, then I will even the odd." Nexus respond before pressed one of the buttons on his belt.
Soon the tree branch in his hand becomes a staff like a weapon, Nexus soon spin the weapon in his hand and charged forward at El of Water in the process.
El of Water soon blocked the incoming attack with his own spear weapon before attacked once again, but Nexus leap backward to avoid the spear weapon.
Soon Nexus pressed onto the button of the belt and his staff weapon becomes a sword in the process. He charged at El of Water and slashed him across the chest several times before forcing him few feet back.
However, El of Water managed to get up from the ground and the wounds that he received from Nexus glows before regenerated in the process.
"No way!" Nexus exclaimed in shock.
Soon El of Water vanished into thin air as Nexus looks around before being slashed from behind. This caused Nexus to stumble few feet back before the Rider tried to strike back against the Lord. But El of Water vanished once again after he tried to swing his sword and the Rider turns around to block the incoming strike with his sword despite being pushed backward.
Soon El of Water's eyes glow before water like serpents come out of the wet ground and tried to strike down on Nexus who did his best to dodge them, but he didn't last long when they all come on him and was sent rolling across the ground.
"Isamu-nii!" Lora cried out after finding her brother not far from where he was.
"Don't get any closer, Lora!" Nexus said, struggling to get back up from the ground.
El of Water stares at Lora before waving his hand to send water snake at her, but Nexus throws his sword at the Lord's face to make him lose his focus.
"Your enemy is me, Lord…" Nexus shouted serious.
"Isamu-nii, maybe it time to use the other cards since they might work on this guy!" Lora suggested.
"I am way ahead of you, Lora." Nexus spoke before getting out a different Rider Card from his Card Holder.
"Blade-san!" Nexus shouted as he drew out the next Rider Card.
KAMEN RIDER BLADE!
Appeared on his right side was none other than Kamen Rider Blade before Nexus picks up his next card.
"Stronger-san!"
KAMEN RIDER STRONGER!
Appeared on his left side was none other than Kamen Rider Stronger.
"Time to bring the storm on!" Nexus declared crossing both his arms together before raising his Nexus Ring into the air.
NEXUS FUSION!
Nexus's Ancient Legend form vanished and replace with glowing bright light as Blade and Stronger glow in their respective colors before merged together with him.
NEXUS: LIGHTING BRAVE!
Nexus soon donned in a black and cobalt blue bodysuit with red lines coming from the arms and legs. There are crisscrossed strips of metal on the boots. He has red chest armor with a silver shaped spade symbol in the middle of it. Attaching to his shoulders are two silver shoulder pads with gold and red lines on them. There is a silver belt around his waist with something resembled a red star in the middle. His helmet resembled that of his previous form but is blue with red lines and there is a silver faceplate attached to the face with green eyes.
This is Kamen Rider Nexus Lighting Brave!
Nexus let out a growl in the air as electricity was shot out of his body and everywhere in sight. Nexus soon charged at the Lord who blocked the incoming kick, but El of Water ends up getting electrocuted in the process and giving Nexus more chance of attacking by jabbing his fists into the stomach.
This sends El of Water rolling across the floor in the process while still being paralysis in the process.
"This is your chance, Isamu-nii!" Lora shouted.
Nexus soon let out a roar before his entire body steaming up and electricity jumping out of his body before he leaped into the air.
Nexus did multiple midair flips as he gathered electricity in the air before descending down with a flying kick with his right leg glowing with intense electricity. El of Water couldn't get away from the incoming kick as Nexus smacked him hard to several trees in the process and caused an explosion at the same time.
After the explosion faded, El of Water's body soon vanished completely before revealed what looks like a gold pillar.
Nexus's Rider form soon vanished into the thin air after the armor detached from Isamu's body. Isamu was panting a little before he gets himself back up.
"I better get out of the rain," Isamu said, taking out the Nexus Ring. He then pointed the halo-like ring at the gold pillar. Soon enough, the gold pillar was soon absorbed by the halo ring and vanished as a new card appeared in front of him.
Isamu took the card and looked at it. In the card, it was an armored warrior donned black bodysuit and golden around his chest, wrists, knees, and ankles. The helmet is black with a golden piece in the middle separating the red eyes and silver mouthpiece. There are set of horns cresting on the forehead with a small blue gem in the middle.
"Kamen Rider Agito… the one who fought against the Lords," Isamu said, looking at the new Rider Card.
Elsewhere, the black hooded figure looking at the card that just appeared in his hand and it was none other than El Lord of Water.
"Well done, Nexus." The black hooded figure commented. "While you're gathering more power, so will I... keep up the good work…" He turns around and leaving through the dark woods.
AN: That is the end of this one-shot. This is what I have for my unique Rider who can fused like Ultraman Orb which served as sort of Decade in my Rider fic. As for why I used Nier: Automata, I want to try something with being last human on Earth things. Anyway, be sure to review or message me for any questions, comments, or concern. And don't be afraid to look at my other stories.
