======>Battleground<======

Both Ethan (Primordial) and A.R. Gabriel (Absolute Decade) faces against each other and they both pulled out their Ride Bookers and transformed into their swords as they clashed their blades.

A.R. Gabriel (A. Decade): *glares* You're very good, for a Destroyer of the Universes.

Ethan (Primordial): *smirk* Hmph, you're much pretty weaker than Original Decade.

Then Gabriel growls at him as he kicked and brought out Carni-Virgo card, and he puts inside his driver.

Announcer: DARKAIJU RIDE. CARNI-VIRGO!

He transformed into Carni-Virgo the Symbiote Dragon Hybrid.

Gabriel (A. Decade/ Carni-Virgo): *scoffs* Tch, You think you can stop me in this form. 

He uses his tendrils to attack him, Kamen Rider Primordial dodges his tendrils as he brought out his Kabuto card and puts in his driver.

Announcer: KAMEN RIDE. KABUTO!

He transformed into Kamen Rider Kabuto.

He charges towards him as Gabriel in his Decade/ Carni-Virgo form uses his tendrils to strike him, Ethan (Primordial/ Kabuto) dodges his tendrils as he grabbed his attack card and puts inside his driver.

Announcer: ATTACK RIDE. CLOCK UP!

He stops everything and Gabriel moves slowly as Ethan zooms towards him, he pulls out his final attack card and puts inside his driver.

Announcer: FINAL ATTACK RIDE. K-K-KABUTO!

He twist kicked him from behind as Gabriel (Absolute Decade/ Carni-Virgo) exploded while blasted away as he turns back to normal form, he crashed into the wall as he got back up and growled at him.

Gabriel (A. Decade): *stern* You think I will lose to you *pulls out the Illusion card* let's see if you can handle all of me. 

He puts it inside of his driver.

Announcer: ATTACK RIDE. ILLUSION!

He summons all 10 of himself & surrounded him, and he chuckles evily.

Gabriel (A. Decade): *evil chuckles* You can't stop me now Primordial, you should bow to me.

Then Ethan smirks in his helmet. 

Ethan (Primordial): *smirking* Oh really, I think I have backup.

He brought out his Summoner Gun.

Gabriel's eyes widened at Ethan's new weapon.

Gabriel (A. Decade): *eyes widened* NANI! That looks like Diend's Driver!

Ethan (Primordial): *smile* FYI, I did met him in person. But, he created this for me to summon them as well. Let's see 'you' can handle this.

He pulls out 5 Kamen Riders Cards: Kuuga, Agito, Ryuki, Faiz and Blade, and he pulls out 5 Daikaiju Heroes Cards: Virgo, Vigo, Kirgo, Titanus Virgo and Virgo Jr. Then he mixed them all together into one card as he put it inside his Secondary Driver Gun.

Announcer: ATTACK RIDE. GEKIJOUBAN!

He summons 5 Heisei Riders and 5 Heisei Kaijus.

Then Gabriel's eyes widened that he could summon all of Heisei Riders & Daikaijus, they charged towards Gabriel's clones and they began to fight. Ethan charges towards Gabriel as he punches his face and he fell on the ground, and Gabriel got back up as he growls at him and now he gotten anger.

Gabriel (A. Decade): *anger* DAMN YOU, PRIMORDIAL!!

Ethan (Primordial): *chuckles* Onore, Decade.

Then all of Heisei Riders & Daikaijus defeated all Absolute Decade clones and they transformed back to cards. Ethan walks towards him, but Gabriel kicked him from behind and he pointed his sword at his neck.

Gabriel (A. Decade): *evil laugh* Don't think it's over yet, I will be the King of all Riders & Daikaijus soon. Muhahahaha!!!

Suddenly, he got kicked from beside him and he got punched in his chest. Ethan turns back and his eyes widened at the new kaiju's appearance.

Ethan (Primordial): *eyes widened* What the hell! New Kaiju!

As for Gabriel, he got back up and he sees a new kaiju as well.

Gabriel (A. Decade): *eyes widened* What! A new one, who is this one?

https://youtu.be/Uj8XB_vlAtQ

Then it reveals a red dragon, with horns-like antlers, hair, spike tail and his arm blades, even energy cores on his legs, arms, ribs, shoulders and chest.

Then Gabriel chuckles at his new opponent.

Gabriel (A. Decade): This new kaiju's power will be mine right now.

He yells in battle cry while he's charging towards the new kaiju, but the red dragon kicked him in front of him. But he grabbed his arm and slammed him to the rocky wall and he slammed him to the ground as he grunted in pain, Ethan stood there as he brought out his KaijuDex.

He pressed the buttons while he was scanning at the new kaiju, and he completely scanned him.

Ethan (Primordial): *amazed* Whoa, this one is a new kaiju.

It revealed his bio on the KaijuDex.

Ethan (Primordial): It was long thought that the three Yamato Guardians, Baragon, Manda, and Varan, were the only ones of their kind. A new find shows that they were a smaller class. The Yamato people also put their faith into a fourth guardian monster. But this was a "master" Kaiju. For centuries, this Master Guardian, NIKKUGON, sat ever watchful, intent on protecting Japan from whatever may threaten it. While Baragon wielded Earth, Manda wielded water, and Varan wielded wind, Nikkugon wielded fire. This ancient dragon rises every 500 years to defend the Land of the Rising Sun from the forces of evil.

-According to ancient scrolls, Nikkugon bonded with Princess Anzu of the Yamato people in order to defeat Camazotz. The demon was defeated, but Nikkugon also suffered heavy damage, and was put to sleep to heal. Now, however, Nikkugon was awoken prematurely when his tomb was captured by Kyle Weaver for his weaponization project. Fortunately, Nikkugon had anticipated such an event, so he forged a new psychic link with Anzu's descendant, Ryoko Nishimura, who wasted no time in freeing Nikkugon. Now, the monster gathers the other Earth Defenders to counter the rising threat of the Exif and Bilusaludo.

Ethan (Primordial): *shocked* Wow, that's a cool name for this Kaiju. Nikkugon! He has Fire breath, Lava spheres from hands, Bladed arms for defense and offense, Grows stronger around hot regions or fire, and weaker around colder regions, Bladed tail, Agile and fast, Skilled at many martial arts, Communicates to humans and Kaiju telepathically, Can draw more power by establishing a link with a human host and Can convert excess energy into Magma Shockwaves. Wait *eyes widened* He can link with human host *amazed* Now that's cool.

Then Nikkugon uses his Bladed arms to slash Gabriel while he's grunting, Nikkugon uses his Lava Sphere and he throws it at him as he blasts him away. Gabriel (Absolute Decade) was about to pull out his card, Nikkugon tail whipped him away as he crashed into the wall. Gabriel (Absolute Decade) growls at him.

Gabriel (A. Decade): *anger* GRRR!!!! WHY CAN'T I DESTROY YOU ALREADY! HOW DID YOU BECOME MORE STRONGER THAN ME!

Then Ethan (Primordial) uses his secondary driver gun and it analyzes him, and he summons the card of Nikkugon. He puts it inside of the Secondary Driver.

Announcer: KAIJU ATTACK RIDE. NIKKUGON BLADED ARMS!

He summons both blades on his arms as he pointed at Gabriel, and he faces back at Nikkugon.

Ethan (Primordial): You're ready?

Then Nikkugon nodded, as Ethan faces back at Gabriel.

Ethan (Primordial): Let's do it.

He pulled out the final card and put it inside of his driver.

Announcer: FINAL KAIJU ATTACK RIDE. N-N-NIKKUGON!

Both Ethan & Nikkugon sprouted their blades from their arms as they charged towards Gabriel, and they slashed him multiple times and they finally slashed him with an X symbol. Gabriel screamed in pain while his body began electrocuting. 

Gabriel (A. Decade): *angered* NOOOO!!!! HOW IS THIS POSSIBLE, I'VE BEEN DEFEATED BY THE DESTROYER OF THE UNIVERSE! DAMN YOU PRIMORIDAL!!!!!!!!!!!

He fell backwards as he exploded & unconscious, finally Brandon came out of the dimensional gap.

Brandon: *shock* Whoa! I'm impressed that you defeating him.

Ethan transformed back to his normal state.

Ethan: *smiles* Ah, it was nothing. His powers are lower, mine is higher. He's just a rookie, and now...

He walked towards A.R. Gabriel's unconscious body as he stomped on his chest.

Ethan: *smiles* I'm the King of Riders & Daikaijus.

He summoned the Dimensional Gap as he threw A.R. Gabriel back where he belongs, he faces back at Brandon but he's nowhere in sight.

Ethan: Hmm, I guess I'm on my own. Well, back to Union-Verse. I bet Yang, Fuyumi and Winter are probably waiting for me, welp gotta get back to my home.

He summons the Dimensional Gap as he walks through it, as for Nikkugon watches him leave. He also senses that the DaiKaiju Warriors are in Ever After, he follows their scent to get them back to the human world.

======>Back in Decade's World (AlstonChanAlstonChan Universe)<=======

A Dimensional Gap has been opened, A.R. Gabriel has been thrown through the gap and it closes. When A.R. Gabriel's eyes waking up, his eyes shot opened that he came back in his world and he finally gotten angered.
