Takeru was on the last of his strength on fighting off the Dustards, hoping to distract them enough for his friends to escape, the friends he betrayed. He already betrayed Tai, but maybe the Kamen Rider Club will be able to figure out how to free their Digimon friends.

Before T.K. could fall on his knees and give up, he was caught, caught by something he thought he killed, it was Tai! Hikari, Sora, Matt, Mimi, and Izzy couldn't believe their eyes. Looking beaten but looking like he woke up as a new man. Jo came walking in with a briefcase in his hand.

"How is this possible?!" Aries Zodiarts looked in shock before regaining his composure. "Get them!" He ordered the Dustards.

The Dustards charged towards the teen but Tai was able to fight them off even without his Fourze suit.

"Tai… You're alive!" T.K. still couldn't believe what he was seeing. "I can never make it up to you… What can I do to apologize?"

"What's that?!" Tai had a Dustard in a headlock. "You don't need to apologize for anything!" He kept fighting off the Dustards. "We both fight with all our might for our Digimon buds! You won last time, that's all!" Tai punched another Dustard. "We've been friends since we were kids, you were always a good guy because you fight for your friends!"

"Tai…" T.K. looks at Tai with gratitude before blocking an attack by a Dustard.

T.K. held the Dustard in place before Tai was able to kick the footsoldier off of him and finish the rest of the Dustards.

T.K. almost lost his balance but was caught by Tai once again. Tai held T.K. and looked him straight in the eye.

"We're buds, T.K. there's not even a shred of doubt left." Tai turns to the others. "We all understand the real him now, right?"

"We're not idiots, of course, we do," Sora gave the boys a reassuring smile.

"We're brothers aren't we?" Matt gave them a nod.

"That's why… I forgive T.K.," Mimi began sniffling.

"A murdered victim shouldn't be forgiving him," Izzy was sniffling as well but agreed with Tai like the others.

"This is Nii-san alright," Hikari says with tears falling down her face.

Jo just adjusted his glasses and gave a firm nod.

"I'm troubled, so I won't be responsible for what happened?" T.K. still looking unsure.

"Just what I wanted!" Tai padded T.K.'s arm. "I love it when my friends give me trouble! I've been doing that to you guys since we were kids."

Tai held out his hand in front of T.K., the latter saw and was hesitant to grab it but grabbed hold of it anyway. Tai then gave the T.K. the handshake of friendship, having both teens smile at each other.

"Your third-rate act ends here," Aries Zodiarts interrupts the moment.

"Well, it's 100 times better than your shitty scenario!" Tai exclaims as he takes out the Fourze Driver. "I'm about to open your eyes, Yamada!" He then placed the Driver on his waist.

"Haven't you forgotten Aries' power?" The Zodiarts reminded the DigiDestined.

"Sorry, but your power no longer works on Taichi!" Jo shouted.

"Right now, my body…" Tai pumps his chest as he holds out a new Astroswitch. "... Is super strong!"

He then inserted the new large Astroswitch on the far right of the Switch Sockets.

COSMIC!

Tai then flips the red Transwitches down, turning on the Status Monitor with each thrown Transwitch, to begin the countdown.

THREE!

His friends watch on.

TWO!

T.K. watches more closely.

ONE!

Aries Zodiarts aims his scepter at Tai firing balls of energy at him.

"Henshin!" Tai pushes the Enter Lever on the right side of the belt and raises his right arm in the air.

A huge puff of smoke came out of his belt with vapor coming out of a rocket creating a gust of wind. A cybernetic circle appeared around Tai's waist and levitated enough to be above his head. Tai was then consumed by a flash of light and when the light died down he was now Kamen Rider Fourze.

He opened the fortieth Astroswitch and pressed the red button.

COSMIC ON!

Jo opened the briefcase and led out all of the Astroswitches, the Foodroids came hopping in and released their Astroswitches.

Every thirty-nine Astroswitches flew towards Fourze as energy surges around him while bombastic space music played and energy around died out showing Fourze in a new form.

Fourze wore a new bright sky blue spacesuit with sides of his arms and legs colored black. He still kept his white Module Basements but with the center being sky blue as well. He had white gloves and black knee pads. He wore a black chest armor where all 40 of his Astroswitches can access. The front chest armor had silver rocket wings attached to it. Finally, the helmet now looked like a rocket ship with wings and black and yellow spots along with the red compound eyes. Now with the power of the 40 Astroswitches and combined with the bonds of friendship! This Kamen Rider Fourze Cosmic States.

In his hand was a sword called the Barizun Sword.

"Uchuu…" Fourze crouches down before pumping his body up and his arms high in the air. "...KITAAAA!" He shouted to the sky that couldn't probably be heard not to other planets but to other galaxies.

Fourze's friends looked at him with awe and couldn't believe the new power Tai had received.

"Kamen Rider Fourze! Taiman harasete morau ze!" Fourze declared.

"I'm not someone who falls for a bluff," The Zodiart said.

Aries Zodiart charged forward aiming his staff at the center of Fourze's chest, but the latter created a small cosmic force field that pushed Aries Zodiart away.

"Fourze Cosmic States has the power of all forty switches," Jo explained. "That attack won't leave a scratch!"

Fourze opens up the Barizun Sword rocket shell showing the weapon's blade. Fourze presses one of the Astroswitch symbols that are on his chest.

ROCKET!

Fourze opens his hands and the Rocket Switch spawns on his hand, he then inserts the Rock Switch on Barizun Sword's Switch Slot.

ROCKET!

He then pressed the switch trigger.

ROCKET ON!

He then presses another Astroswitch symbols that are on his chest

ELEC ON!

"Here I go!" Fourze shouted

Fourze boosted himself with the rockets on his back and Barizun Sword's blade covered in electricity.

Fourze landed in front of Aries Zodirat and gave him powerful electric slashes, sending the enemy back.

"Amazing, Nii-chan is able to add other Switches' power to his weapon!" Kari looks at her brother in awe.

Aries Zodirat growled and fired more energy blasts at Fourze but the Rider dodged the attack by jet-packing away.

Fourze flicks the Launcher Switch on his Driver and pressed the Freeze Switch symbol on his chest.

LAUNCHER ON!

FREEZE ON!

The Launcher Module fired five ice rockets at the Zodiart and hit around him, sending the Zodiart sprawling through the air. Once Aries landed on the floor his whole body froze turning it into ice.

Fourze then summons another Astroswitch.

FIRE!

Fourze summoned the Fire Switch before inserting the Fire Switch on Barizun Sword's Switch Slot.

FIRE!

He then pulls the Switches' ring activating its power.

FIRE ON!

Fourze then used the fiery energy blade which extended to great lengths and slashed at the frozen Zodiart, freeing him and damaging him as well.

Aries was getting angry so he turned into his Supernova form.

Fourze removes the Fire Switch and then proceeds to close the Variant Cylinder encasing the Barizun Sword's blade.

Fourze then removes the Cosmic Switch and inserts it on the weapon's Switch Slot.

LIMIT BREAK!

A portal appeared behind the Zodiart but Aries didn't pay any mind as he fired energy balls at Fourze.

"Using our bond, we will grab onto space!" Fourze proclaimed.

Using his jet-pack, Fourze rocketed forward to the Zodiart and pushed him into the portal. The portal sends them into space.

"Was that a warp drive?!" Aries questions the Rider.

Fourze didn't answer as he proceeded to open the Variant Cylinder, unsheathing the blade. The blade lets out cosmic energy as Fourze removes the Cosmic Switch before putting it back in.

LIMIT BREAK!

Fourze covers the Barizun Sword in cosmic energy.

"Rider Chō Ginga Finish!" Fourze announced before he delivered a powerful slashing maneuver at Aries Zodiart.

The energy slash flew towards the floating Zodiart before it hit the villain, giving out a huge explosion and making him lose his Zodiart Switch.

Back on the ground with a defeated Yamada, Jo ran towards him and grabbed a device from his pocket. Jo presses a button and frees all their Digimon friends.

"Patamon!" T.K. cried out as the Digimon jumped into his arms.

His fellow Digimon jumped into their respected partner's arms.

T.K. stops his hugging and turns to the other DigiDestined.

"Everyone, I'm sorry!" T.K. bowed to them.

The rest of DigiDestined looked at each other before they started laughing.

"As Tai said before, "We're buds so all is fine"," Jo smiles at him.

"Takeru, did you guys get into a fight?" Patamon asked.

T.K. gave a small chuckle, "Just a small scuffle, Patamon. Just a small scuffle."

AN: What do you guys think, a pretty creative idea, right? And yes their appearance is from Digimon Tri. so don't think of them as children. I check the crossover of Digimon x Kamen Rider list and saw there was no Fourze idea, so I thought, hell yes I can make this one-shot. Tell me what you think about it, please.
