I don't own Fate/Stay Night or Kamen Rider and they belong to their respected owners.

Rin was on the top of the roof of Zect. She and Shirou heard Zect had this new armament which could help Shirou boost his power as Kabuto. So right now she was caring a silver briefcase with the Hyper Zecter.

Now she is stuck on the roof with Ryuunosuke with Kirei by his side and the ZectTroopers surrounding her. She was glad she ordered Archer to handle Lancer till Shirou and Ritsuka came.

"Hand over the Hyper Zecter," Uryuu ordered her.

"No, I won't let you misuse this power!" Rin shouted.

"If you give it back you'll be spared," Kotomine tried to persuade her.

"My answer is still no!" Rin said.

"Give it to me!" Shouted a voice.

They all turned to see the Uca Worm jump up to the top of the roof with Cammarus Worm and Salis Worms joining her side. The Uca worm shows the face of Maiya Hisau.

"How about I let all you live if you give it to me," Uca threaten them.

"So this is what you were up to," Ryuunosuke not looking surprised.

"Give it to me," Maiya ordered Rin. "I'll guarantee your life."

"Never!" Rin shouted and in the corner of her eye, she saw Shirou and Saber. "Shirou!"

All heads turned to the young teen and his servant walking towards them.

"Don't worry Rin I'll handle this somehow," Shirou said.

Under the helipad, Ritsuka was hiding under it on the stairs holding his Gatack Zecter ready to assist Rin. Rin looks at the two groups than at her fellow master and decided to make a break for it.

"Shoot Renge!" Ryuunosuke orderd.

The ZECTroopers aim their guns at Rin and began to fire.

Ritsuka inserted his Zecter on his belt.

"Henshin!"

HENSHIN!

"Cast Off!"

CAST OFF!

Ritsuka used to clock up to run in front of Rin taking the shots for her.

"Saber make sure there aren't any other servants coming," Shirou told her.

"Yes, Shirou," Saber nodded.

"Henshin!" Shirou inserts his Zecter to his belt to transform into Kabuto.

HENSHIN!

As Gatack kept blocking the bullets it gave Uca a chance to tackle Rin off the building.

"Saber help Fujimaru, kill only the worms!" Shirou told her as he jumps off the building to rescue Rin.

"Cast Off!"

CAST OFF: CHANGE BEETLE!

Kabuto removes his armor and free-fall to Rin. He reaches his hand out, it looks like he was reaching for his case but pass through the case and catches rain in a bridal style.

Uca catches the case. "I got it!" Uca opens the case to see the Hyper Zecter and a device that was beeping.

Ryuunosuke pressed a button on a stick which made the briefcase explode taking Uca and the Hyper Zecter with it.

"The Hyper Zecter!" Rin couldn't believe it was gone.

"Better to destroy it than let you obtain," Ryuunosuke smirked. "Kabuto... I just destroyed your future."

"You bastard!" Rin growled.

Rin stops glaring at the man when she felt Kabuto hand on her shoulder.

"Zect never looks towards the future," Shirou said. "You only fight to win, for power but I fight for the future and I still feel it in my grasp."

Kabuto holds his hand up as the Hyper Zecter suddenly appeared in his hand.

"Impossible!" Kirei look down where Shirou and Rin was.

Shirou then placed the Hyper Zecter on the left of his belt then turn it 90 degrees clockwise so the horn pointed up.

"Hyper Cast Off," Shirou pushed the horn lever of the Hyper Zecter down.

HYPER CAST OFF:

The chest armor became a little more bucky as well as changing it to red and silver and gave him a silver plate of armor on his back. changing appearance to being silver with the center looking like a red kabuto horn, the hands turning red as well as his right foot, the armor plates on his legs changing red and the horn on the helmet began to grow in size. The helmet as well changed colors from red to silver, the silver armor on his arms and legs changed to red. His blue bug eyes became cyan. Now Shirou became Kamen Rider Kabuto Hyper Form.

CHANGE HYPER BETTLE!

"What is this?" Kirei looked at Kabuto in shock.

Rin smiled seeing she was able to help Shirou with gaining the Hyper Zecter to gain his new Hyper Form.

"Shirou…" Saber looks at him in awe as she saw her master's new form.

The Cammarus Worm began to power up his hooked claw with electricity. It then jumped up and punch Ritsuka send him back.

"Raaahhh!" Ritsuka screamed as he exploded from the Cammarus attack.

"Ritsuka!" Saber shouted as she saw Gatack screamed to his doom.

Shirou pressed the Hyper Zecter button activating it Clock Up.

"Hyper Clock Up!" Kabuto said.

HYPER CLOCK UP!

Kabuto's chest open to show the yellow center as yellow wing pop open from his legs and wrists. The silver chest piece from his back open as well which activated the jets which made the flames look like wings. Everybody was in awe by Shirou using the Hyper Clock Up ability as he disappeared from thin air.

"M-master?!" Saber shouted. "Where did he go?!"

"It's the power Hyper Zecter," Rin smiled. "When Shirou and I heard about the Hyper Zecter. The Hyper Zecter has the ability to go back in time."

The information surprises everyone and wonders when Shirou went.

The Cammarus Worm began to power up his hooked claw with electricity. It then jumped up to punch Gatack but its claw was caught by Kabuto as his armor close.

HYPER CLOCK OVER!

"Shirou?" Rituska surprise to see the red Rider.

Shirou punches the Worm away. The Cammarus Worm tried to hit Kabuto but the beetle Rider was able to dodge all its hits and gave the Worm a beating of its own. Shirou gave it a couple of good punches sending the Worm to the air.

Shirou then presses the Hyper Zecter again activating the Clock Up.

HYPER CLOCK UP!

Everything slowed down even the Cammarus Worm. Shirou pushed the horn lever down initiating his finisher.

MAXIMUM RIDER POWER!

Shirou pressed the buttons on the Kabuto Zecter's "legs" in order

1-2-3!

He then flipped the horn to its original position allows the Shirou to charge up for his Rider Kick

"Hyper Kick!" Shirou announced.

Shirou pulls the Kabuto horn back across its "body".

RIDER KICK!

Shirou jumps up higher with his jets and stretches out his right leg to initiate the kick. His foot was covered with energy and met his foot to the Cammarus Worm's chest destroying it in a large blue explosion.

HYPER CLOCK OVER!

The Hyper Zecter deactivation announced as Shirou landed with his armor closing back up. Ritsuka looks up at Shirou not sure what just happened.

"Shirou, I don't understand what is this new form? I thought the Zecter was destroyed?" Saber asked when she walked to his side.

"It traveled through time to recreated the future," Shirou said. "A better future."

AN: Not my best work but I did this one-shot and did it under three hours. I just wanted to get it done. Now all I have left is Hibiki and Faiz then I can work on my new Decade story that I have been working on. Also, I know Tendou Souji's name means "Walking the path of Heaven, the man who will rule over everything", and Shirou doesn't but that doesn't mean a grandmother wouldn't encourage her grandson with that quote.
