Let me get one thing straight, I have no ownership over any Kamen Rider Series. At least Toei doesn't hate on this site like they do a certain video-sharing site.

Warning: May be alternate versions of each Rider, supporting Rider, supporting characters, etc.

OOO: The Yellow Jacket, The Letter W, and Uva

Jordan Payne, Kamen Rider OOO, was chasing a yellow-and-black winged Yummy on a Ride Vendor that he spent a Cell Medal on. The Yellow Jacket Yummy was soaring through the skies, firing yellow lightning blasts at him. The Rider managed to avoid the attacks as he stopped the bike.

On another Ride Vendor came his Greeed partner Ankh, who had taken the body of the wounded police officer Jason Calvin.

"Ankh, medals!" Jordan ordered.

"Don't order me around."

"Spare me. Give me the fucking Cores."

Ankh let out a growl, and tossed Jordan three medals: one green, the second one red, and the last one blue. Jordan put the OOO Driver to his waist as a belt formed for him to deposit the three Core Medals into the slots. From his right, he grabbed a scanning device to scan the Medals.

"Henshin!"

"Kuwagata! Kujaku! Tako!"

OOO's Peacock Wings spread as he took to the sky after the Yummy, who fired more of her lightning balls at him.

"You'll never catch me, OOO!"

OOO concentrated as he fired off a lightning blast using the Kuwagata Medal's power. Watching the Yummy spiral toward the ground one after one of her wings disintegrated, OOO realized this was his chance to bring this fight to an end. He opened the Taja Spinner, replacing the Cell Medals inside the O Crown with the three Core Medals he was using before scanning said Medals.

"Giga Scan!"

OOO swooped down toward the Yummy, the Taja Spinner glowing. Before he could connect with his finishing move, a green blur dove in front of the Yummy and delivered a Roundhouse Kick that knocked him to the side, into a pile of barrels.

The Kamen Rider got up, seeing a bug creature walking toward him.

Uva. The Insect Greeed.

"Hey there, OOO," said Uva menacingly. "I see you've been keeping my Core Medal warm for me. Yeah, you should hand it over."

Before Uva could advance any further, he was hit in the back with a blast. Ankh looked up.

It was a steel-and-black colored Kamen Rider with a green visor, armed with a cannon sticking out of his chest. Standing next to him was a medium-sized black man with an unkempt afro and beard, armed with a blaster that looked like it belonged to the Rider.

"Hey, Payne- I see you've gotten yourself into another mess," said the newcomer to the battle. "Alvin, I'm gonna distract this Greeed long enough so you can get to Jordan."

"Got it," replied the other man.

"Come and get it, Bug-Boy!"

"The nerve you have, interrupting me!" Uva snapped. "No matter, I'll just kill you quickly, then I'll get Ankh. That little bastard has my other Medal."

"I'm gonna make you a giant smear on my Hustler."

Struggling to get to his feet, OOO shook his head as Alvin assisted him.

"Hey, Jordan."

"What brings you and that pervert Joe here?" OOO asked.

"Birth is distracting Uva, so you can catch the Yummy," Alvin replied.

Suddenly, Ankh ran over to the two.

"Jordan, use these," the Greeed suggested, holding out two more blue Core Medals.

"Thanks, Ankh."

Alvin and Ankh stood back as OOO replaced the green and red Medals for the other two blue ones. The Kamen Rider scanned them...

"Shachi! Unagi! Tako! Sha-sha-Shauta! Sha-sha-Shauta!"

The Ocean Combo was in effect, as OOO wielded the full power of the late Greeed Mezul. The Rider jumped back into the fight, which Kamen Rider Birth was losing fast. Birth had fired two blasts from his Breast Cannon, neither of which had had any effect on Uva.

OOO: "C'mere, Uva! I've got a shocking present for you!"

And OOO lashed the green monster with the twin Unagi whips, sending surges of electricity throughout the Greeed.

OOO: "Hey, Slater, you and your boy here go after the Yummy. I'm gonna knock Uva out of the park."

Birth: "My pleasure."

Birth and Alvin took off, leaving OOO alone with Uva.

"I'll be taking those Core Medals of yours really soon, OOO," Uva hissed.

Then, I'll have the power I need to evolve and finally crush that bastard Cazali! He wants an evolution, I'll show him.

Uva ran at OOO, who ducked under a spinning kick and answered with a kick to the body. Uva responded with swipes at OOO from his claws, the Kamen Rider guarding pretty well and responding with more strikes from his Eel Whips. Each lash made Uva back up a bit.

Until using the Shauta Combo now, OOO had never been able to fight Uva so easily.

"Jordan, finish him!" Ankh yelled.

Jordan grabbed the O Scanner, scanning his Core Medals.

"Scanning Charge!"

This would be Jordan's chance to take down another Greeed, as well as Ankh's opportunity to gain more Core Medals. The Kamen Rider became pure liquid as he took the skies, wrapping Uva in his Eel Whips and bringing him upward as well. The Tako Legs began spinning as OOO started to descend for his finisher, the Octo Banish. The insect monster could do nothing to stop his demise as OOO came down, the sky raining Medals.

Ankh detached himself from Jason's body and managed to grab the two Kuwagata, the three Kamikiri, and the extra two Batta Medals while in midair. As he focused on the Medals, he never saw the feline hand that grabbed him.

"I'll be taking my Medal back now, Ankh."

"Cazali!" Ankh hissed as Cazali released him.

The feline Greeed backed off, now holding the last Tora, all three Kuwagata, and the two Batta Medals as he absorbed it. He seemed to change, now gaining more body armor.

"Ah, I'm complete once more!" Cazali said, with a feeling of satisfaction.

OOO turned around, sensing power unheard of as he realized the horrible truth of Cazali reaching his complete form.

But there was one more horrendous truth: Tatoba and Gatakiriba Combos were now impossible.

"Cazali?"

The Greeed turned around.

"OOO," Cazali sneered. "Now you know my true form. And check this out, I've got a power bonus."

The feline monster stomped the ground, sending a water-filled shockwave in the direction of the Kamen Rider that rocked him out of his transformation.

Watching the battle from far away was the Kougami Foundation's scientist: Dr. Kiyoto Maki, the man who held death and endings to a higher degree. He had a project of his own: to seek a container for all the Core Medals.

"Finally, the result I wanted."
