Chapter 11: Kamen Rider Simeon

Middleton Colorado February 19th 2007 Hours UTC-7:00

Katie Taylor, also known as Kamen Rider Jaeger, looked down to a couple driving a purple car next to a High School in Middleton, Colorado. She then took notice to a boy with the girl holding an Advent Deck with the symbol of a monkey appearing on it. She smirked and then held out her Advent Deck, the electricity sparking through her.

On the ground below, the couple, Kim and Ron, were having a fun time with each other. Ron's eyes then narrowed as he reached for his Advent Deck, as Kim reached for something in her backpack. "Are you sure you'll be safe?" Kim asked.

Ron sighed and then looked back to Kim, shaking his head. "I'm never sure." He replied back with much stoicism in his voice. Kim just shivered at the thought of her boyfriend getting Vented before Ron then turned around, towards a tree, his Advent Deck glowing brown while the hidden attacker's Deck glowed the same color.

"KAMEN RIDER!" the two then called out.

Ron and Katie both glared at each other, their Advent Decks colliding with one another. The two pressed their Decks against each other before slamming their Advent Decks together. They then pushed each other off as their Belts appeared. They slotted their Advent Decks into the Belt Buckles, causing them to spin. The two then spread their arms out and let rings encircle around them, spinning around and sparkling with electricity.

Katie finished with her transformation, now becoming Kamen Rider Jaeger, her Bounty Visor out in front of her.

Ron finished up his transformation as well, now a Kamen Rider. Ron stood tall in red armor with a yellow chest plate and shoulder pads. Under the armor was a red bodysuit. His gauntlets and boots were black. On his chest were diagonal straps that crossed from his shoulders to his waist, forming a black X. Around his neck was a red scarf. His face was concealed under a red helmet with a crystal orb in the center of the forehead. Ron cracked his neck before getting into a fighting stance.

"You wanna do this the easy way, or the hard way?" Jaeger asked, aiming her Whip at Kim.

Kim just aimed her Wristwatch Kimmunicator at Katie and panted heavily. "You obviously don't know who you're messing with."

Ron held his hand up. "Kim, wait," he said. "I hate to give orders, but you need to stand down."

Kim looked to Ron with confusion. "You told me about the Advent Deck, Ron," Kim said. "You saw the vision of many Kamen Riders all coming together and stopping a great evil." She said. "I'm not afraid."

"She's Xaviax and Xemnas's Assassin Rider!" Ron exclaimed. "She's pure danger!"

"Listen to your boyfriend, girl," Katie stated as she placed her Bounty Visor on her shoulder. "I can vent Simeon within seconds."

Ron gritted his teeth. "Alright, if you want to fight, then I accept," Ron said after some reluctance. "But not here!"

Katie chuckled. "Alright, then," she said. The evil Kamen Rider then looked over towards a pond. "We fight in Ventara."

Ron nodded as Kim lowered her Kimmunicator. She had secretly pressed a button which sent out a distress call. I hope that the Justice League gets this. Kim thought to herself anxiously.

Ron and Katie then glared at each other before walking right into the pond, now entering Ventara.

Mount Justice February 19th 2014 Hours EDT

Batman looked up to a holographic screen, showing Trent from the No-Men. "Do we have any reports of Advent Decks coming in?" the Dark Knight asked.

"Negative," Trent replied back. "All blogs, news reports or camera footage indicates anything for Advent Decks around the world." Trent reported.

Master Eubulon walked up. "People who are finding these Advent Decks won't know what they are or what they do until either I or Xemnas meets them," the Advent Master pointed out. "We have to be patient."

"Right," Trent said. "This is Agent Trent, signing off."

Batman sighed as soon as Trent signed off. "If you need me, I'll be elsewhere." The Dark Knight said, walking over towards a Zeta Tube.

Recognized, Batman 02. The Cave AI said as Batman left.

Nick then walked up to the holocomputer. "It would seem that Riders everywhere are either abusing their newfound powers, now working for Xemnas, or are trying to do what they can to serve justice around the world." The Rider Master stated.

Aqualad and Rocket then walked up. "We already have Artemis as Sage, Maya as Torus, Kamen Rider Twilight and Kamen Rider Eclipse on our side." The Atlantean stated. "How many more Riders are there out there?"

"About more than sixty, according to the vision I had." Eubulon then said.

Kit and Pryce then walked up. "Master Eubulon, Master Kaiser, can we have a moment?" Pryce asked.

Artemis, who was training nearby with Kase, looked over with confusion.

"Is something wrong, Kit?" Nicholas asked.

"You can say that." Kit replied back. "Back in Gramercy Heights, Pryce and I stumbled upon a Kamen Rider, one different than the others." Kit explained.

"He said that his name was Kamen Rider Scathe, and from the looks of it, he doesn't appear to have any loyalties to any side." Pryce said. "We don't even know what kind of Advent Beast he has."

Eubulon paced around. "Interesting," the Advent Master pondered. He then looked to Kaiser. "Master Kaiser, are you familiar with a Kamen Rider like this?" he asked.

Nick just shook his head. "I've heard of many Kamen Riders before, but this one is different. I've never heard of a Kamen Rider Scathe before."

Just then, Kit, Artemis, Pryce and Kase all looked around. A loud distorting sound filled the air before the holoscreen activated. Two figures appeared on the screen, one was a Kamen Rider with red and yellow armor and the other was Katie Taylor.

"Alright, if you want to fight, then I accept, but not here!"

"Alright, then, We fight in Ventara."

Robin started to type at the holocomputer's terminal. "I'm tracking down where that transmission came from now!" he exclaimed.

Everyone present in the Cave looked to the holoscreen, seeing a map of the world. The screen first zoomed into the United States, then to Colorado, and then to a city.

"Middleton." Kit said, looking to the map.

"Kim Possible." Robin then said with interest.

Kase's eyes widened when she heard this. "Who?" Kase asked, furrowing her brow.

"International superheroine," Dick then explained. "After an Alien Invasion Kim and her partner, Ron, stopped, the Justice League made sure to tighten Earth's security."

"Seems to have failed." Kit stated, looking to the Ventaran Kamen Riders.

Eubulon looked to the Riders and nodded. "Kit, Pryce, Artemis, Kase, you go on ahead to Middleton, find out what's going on!" the Advent Master ordered. "I'll call in Len, Chris, Chance and Ian to assist as backup!"

The four Kamen Riders nodded as they started to head towards the main Hangar Bay. Inside, they mounted their bikes and started their engines. "Let's ride." Kit said.

Everyone nodded as they started to drive into the water. Instead of sinking, they entered Ventara, now heading off to Middleton.

Middleton Colorado February 19th 2045 Hours PDT

People all around at the Middleton High School looked to the four Kamen Riders as they entered the area, heading over towards where a purple car was parked.

Kim was looking into the pond where Ron and Katie had gone through before noticing the sound of motorcycle engines revving fill the air. She turned around to then see the Kamen Riders, all coming off of their bikes.

"Let me guess, the Advent Master sent you?" Kim asked.

Kit nodded and held his hand out. "Kit Taylor, at your service." Kit introduced himself.

"Kim Possible, nice to meet you." Kim then said, shaking Kit's hand.

Artemis got off and looked to the pond. "Which Kamen Rider entered the pond?" Artemis asked.

Kim looked to Artemis and then motioned her head towards the pond. "My boyfriend, Ron," Kim explained. "He got an Advent Deck a couple of days ago, and now, he's known as Kamen Rider Simeon."

"Monkey Motif?" Pryce asked as he raised an eyebrow. "Seems to be a likely target."

Artemis nodded as she then took out her Advent Deck. "I'll do what I can to help Ron," the archer said. "I've clashed with Jaeger before, and she's a really difficult opponent."

Kim smiled. "Thank you." The young redhead said.

Artemis looked back and smirked before holding out her Advent Deck. Green electricity started to spark from the Deck and then to her waist, forming the Vent Buckle around her waist. She held out her Advent Deck to the side. "Kamen Rider!" she yelled. With that, she placed her Advent Deck into the V-Buckle, causing it to sink it. The Sage Deck spun around before an Aura surrounded Artemis, letting her become Kamen Rider Sage.

Artemis looked back towards her friends and craned her neck at Kase. "Come on," the archer said. "I might need some help to take on Katie."

Kase nodded. "You got it." Kase said, placing out her own Advent Deck. It started to glow as well before she slotted the Advent Deck into her V-Buckle. "Kamen Rider!" Kase called out. Soon, after a White Aura surrounded her, Kase became Kamen Rider Siren.

The two female Kamen Riders leapt into the pond, now entering Ventara.

In Ventara, Ron and Katie were clashing blades. Ron was armed with his Pek Kwar Staff, and Jaeger was armed with her Bounty Blade. Kamen Rider Simeon twirled his Visor around and stabbed at Katie, but the Assassin Kamen Rider just dodged the jab and performed a high roundhouse kick at Ron, knocking him into a tree.

The tree started to uproot from the impact of Ron's body before Kamen Rider Simeon got up, groaning in pain.

"You may have been fighting against Monsters and Villains for a long time now, but just by looking at you I can tell that you've never gone up against a fully-trained Rider." Kamen Rider Jaeger retorted, starting to stalk Simeon like a predator.

"Wanna bet?!" Ron yelled out, swinging his Pek Kwar Staff around as he got up. The Staff soon extended and slammed into Kamen Rider Jaeger, but it only succeeded in hitting thin air.

"Trick Vent!" Ron exclaimed. He then took out a Card from his Advent Deck and looked around. "Where are you, you coward?"

"Right here!" Katie yelled out.

Ron gasped as he turned around, seeing the real Kamen Rider Jaeger appear with her Bounty Visor ready to lash out at him. Kamen Rider Simeon used a roundhouse kick, which was aimed directly at her head, but she caught his leg before she sent him flying with a powerful forward kick to the chest.

Katie then inserted a Card into her Bounty Visor.

STRIKE VENT! The Bounty Visor called out.

Twin Battle Claws fell onto Katie's hands as she started to advance towards Kamen Rider Simeon. "It's about time I put an end to you, Ron Stoppable." Katie stated. "Prepare to arrive in the Advent Void."

All of a sudden, Ron burst into feathers.

"What?!" Katie exclaimed, looking around. White feathers started to rain down onto the area. Jaeger looked around with confusion and anger before the laughs of Ron, Artemis and Kase filled the air.

"What's the matter?" Kase's voice said. "Afraid you might be ticklish?"

"Not in the least!" Katie called out, slashing all around. "I knew that your Advent Master would send out his Riders instead of face me on his own!" Katie Taylor then exclaimed. "Now face me or be Vented!"

Artemis then jumped out of her hiding place, using her Secret Saber to slash at Katie in the back. Kamen Rider Jaeger groaned and turned around, ready to counterattack, but Artemis disappeared. Kamen Rider Siren then appeared behind Jaeger, slashing her in the back as well.

"Here's the finale!" Ron then yelled. He slotted a Card into his Pek Kwar Visor.

FINAL VENT!

Ron then threw his Staff high into the air, letting it twirl around. Kamen Rider Jaeger looked to it before Ron then slammed his hand down to the ground, causing the Pek Kwar staff to slam down on Katie as well.

Katie gasped and got out of the way, heading into a stop sign. "We'll meet again, Riders!" Katie called out, disappearing out of Ventara.

From the reflection of the pond, Kamen Rider Scathe looked on as everything developed. "I would have never known that more of these Kamen Riders would appear," he pondered to himself. "Just how many more of them are out there?"

Kase, who was helping Ron get back up onto his feet with Artemis, suddenly turned around and took out her Blanc Visor. "Who's there?!" Kamen Rider Siren called out.

Scathe chuckled and disappeared.

"What is it, Kase?" Artemis asked.

"I thought that there was someone watching us." Kase explained. "But… whoever was watching us is gone now."

Artemis shrugged. "It must be that other Kamen Rider that Kit and Pryce mentioned," Artemis mused. She then looked down to Kamen Rider Simeon. "We'd better get Ron back to Middleton, fast."

Kase nodded as she helped her archer friend get Ron back up to his feet. They all then headed towards the pond, now coming out of Ventara.

In Middleton, Artemis and Kase came out, carrying Ron on their shoulders. "He's safe, but he's injured." Kase said.

Kim immediately ran towards Ron. "Ron, are you okay?" Kim asked her boyfriend anxiously.

Ron looked up to Kim and smiled. "Yeah, KP, I'm fine." Ron said. He then looked into his pocket to see his Naked Mole Rat, Rufus, wake up. "And so is Rufus!"

Pryce looked over towards Kit. "He's one strange Rider." The Ventaran stated.

"But he's got heart, I'll give you that." Kit replied back. He then cleared his throat as he approached Kim, Ron, Artemis and Kase. "My twin sister doesn't give up easily, I hope that you realize that." Kit Taylor told them.

"I can see the similarity." Kim mused as she looked to Kit from head to toe.

"We're going to need all the help we can get to take down Xemnas and his evil Kamen Riders." Kit added on. He then held out his hand towards them. "Will you join us?"

Kim and Ron both looked to each other, trying to think of what to do. Finally, they both looked up and nodded, Kim shaking Kit's hand. "We're in." Kim Possible finally said.

Kit smiled as he shook Kim's hand before helping Ron get up to his feet. "Welcome to the Kamen Riders, both of you." He said. "You two should be proud."

Kim and Ron smiled before Pryce cleared his throat. "We should probably head back to the Cave, try and find out where Kamen Rider Jaeger went." Strike suggested.

Everyone nodded as they then got onto their bikes. Kim and Ron both got into the Sloth Car and rode off with the Kamen Riders, heading back through the pond and towards Mount Justice.

From a distance away, a flame started to ignite. Soon, Kamen Rider Scathe appeared out from the flame, his eyes glowing. "Seems that I'll have to make things more interesting." He said to himself.

Back at Mount Justice, Master Eubulon and Master Kaiser looked to both Kim and Ron with interest. Robin pulled up information on the two, which the Advent Master and Rider Master were reading over.

"You both have excellent academic records, and appear to have saved the world plenty of times." Eubulon stated. He then looked to Ron. "But that raises a pertinent question: How did you find out about the World of Ventara and the Kamen Riders?"

Ron sighed as he looked to his Simeon Advent Deck. "When I got this Deck, I got a vision of many Kamen Riders and heroes, all joining together to take down a dark force that would threaten to destroy our Universe as we know it." Ron explained. "I didn't want to let that happen, and I was shown how the Kamen Riders had protected the world from Xaviax before, and how new Kamen Riders were starting to emerge. I wanted to join the movement, I wanted to help prevent the return of Xaviax."

"Ron told me everything he saw," Kim then said. "At first, I didn't believe him, but when a Mirror Monster attacked me, he transformed into Kamen Rider Simeon, and I started to help him fight against the Mirror Monsters ever since."

Eubulon nodded. "I see," the Advent Master stated. "You two will make great allies to us, and once we find all of the Kamen Riders, we will have the strength to take down Xemnas and Xaviax once and for all."

Kim and Ron both nodded at this. "Even though I'm not a Kamen Rider," Kim started to say. "I'm going to fight 'till my last breath to keep everyone safe."

Boulder City Colorado February 19th 2100 Hours PST-8:00

Meanwhile, Kamen Rider Scathe appeared in a Dark Room within the Hoover Dam. As he entered a secret entrance past all of the military security, he started to remove his Advent Deck. However, upon hearing the sound of a tank approaching, he remained in his Rider Form, letting the tank pass. He then slowly placed his Advent Deck back into his V-Buckle before entering the cavern.

Scathe then walked through the secret entrance, which led to a large room full of cages with Advent Beasts and blank Advent Decks scattered all around.

Scathe pulled up a screen, showing Xemnas, JTC, Drew, Apollo the Assassin and Katie talking with the Light in Western Mongolia. "Now, what are you up to?" scathe asked as he started spying on the conversation going on.

"How many Riders must fall to the Advent Master at this rate?" Klarion asked. "If you ask me, I think that Xaviax got what he deserved when he was destroyed by the thirteen Kamen Riders!"

"Never talk about my General that way!" Xemnas called out. "I am doing all I can to bring him back." The Shark Rider then said.

JTC then stepped up, clearing his throat. "Lieutenant, if I may be so bold, I would like to suggest something that I learned from General Xaviax while still serving him." The former Kamen Rider Strike said. Drew, Katie, Apollo and Xemnas then all looked to him. "Do you recall Kamen Rider Wrath?"

Xemnas nodded. "He was Len's teacher, and the Strongest of the Thirteen Riders," Xemnas replied back, indicating that he knew. "What does this have to do with bringing back my General?"

"General Xaviax would always know where every Kamen Rider was at any time, and through the use of his technology and his Transmitters, he could make sure that all Riders, not even the Advent Master or Kit and Len, would be safe from him," JTC stated. "You see, we can LET the Advent Master's Riders think they win each fight, but since all Advent Decks give off an Energy Signature, we'll track them down, and ambush them."

Apollo nodded. "Interesting," the Assassin stated. "It reminds me of General Xaviax's AntiVirus Infection on the Transmitters after the Kamen Riders shut them down. When General Xaviax placed the AntiVirus into only one of the Transmitters, it caused all of them to reactivate, and he was mere seconds away from successfully kidnapping all of the Humans on Earth."

"That's an excellent plan," Katie then said. "All we've gotta do is find one mere human scum with a New Advent Deck and try to place a tracker on it, which will allow us to find the rest of the Advent Decks and the New Kamen Riders easily."

The seven members of the Light all looked to each other. They all nodded before looking back to Xemnas. "Be sure that this new plan works," Vandal Savage ordered. "We expect results… soon."

"Of course, Great and Eternal," Xemnas said. "Your wish is my command."

Kamen Rider Scathe shut down the transmission, leaving the room dark once again. "Such loyalty, such devotion." Scathe said to himself. He then walked up to one of the cages he had. It was full of Gazelles, all wild and wanting to lose control. "You shall have your time, my pets." Scathe then said. He looked over towards where he placed a throne and then chuckled. "Oh, Xemnas, Xaviax will return," he said, now sitting down on his throne. "But just don't be pleased with the results you get." With that, Scathe pressed a button on his throne, causing a large mirror to appear in front of the Gazelles. They all charged right through the mirror, heading into Ventara.

Scathe chuckled at this. He then looked to a Blank Advent Deck and lit up one of his hands. "You wanted a Rider, so here you go!" he exclaimed, throwing the shining Advent Deck out in front of him.

Soon, a purple, magenta and grey-colored Kamen Rider appeared. On his left hand was what looked like the Evil Visor of Kamen Rider Sting, his right hand a gauntlet was shaped like the Veno Saber, and his body similar to Kamen Rider Thrust.

"Kamen Rider Savage," Scathe said. "Rise."

Kamen Rider Savage growled and got up, his fists clenched. "What is thy bidding, my Master?" Savage asked.

"I need you to oversee that the new Kamen Riders in battle, and alert me of any sort of new powers the original Thirteen Kamen Riders now possess." Scathe ordered.

"I shall do as you wish, my Master." Savage said. He disappeared through a portal and made his way towards where the rest of the Gazelle Monsters were headed.

Happy Harbor Shopping Centre February 20th 1423 Hours EDT

The next day, Katie was at the Happy Harbor Mall. She walked out of a store and sighed. "'Go to Happy Harbor', they said. 'Find out if the Kamen Riders are up to anything', they said." She muttered. "I doubt I'd even last a second here without getting caught."

Meanwhile, Kim was walking around the Mall with Artemis. "Artemis," Kim said to the archer. "Thank you for helping to save Ron back there yesterday." Kim said gratefully.

Kim chuckled. "I'm just doing what I know is right." Artemis replied back, smiling. "You see, Kit and I were childhood friends, and we always wanted to protect one another from harm all the time."

"The same was with me and Ron." Kim then said. "Ron saved me from some bullies in Pre-K and we were best friends ever since." Kim reminisced.

Artemis and Kim then chuckled, thinking back to their different childhoods. "Good times, good times." Kim said happily.

While this was happening, Katie was getting off of the escalator she was on. As she got off, she noticed Kim and Artemis walking towards her.

Kim and Artemis continued to walk until they noticed Katie. Both of them immediately stopped and gaped.

Katie Taylor gaped as well, dropping her bags.

"What are you up to?" Kim asked as she narrowed her eyes at the Assassin Rider.

"Can't a girl just shop?" Katie replied back calmly.

"If you're trying to spy on us, then go and tell Xemnas that you saw nothing here." Artemis spat.

Katie sighed, reaching for her Advent Deck in her back pocket. "If that's the way you want to settle things, then so be it." Katie remarked.

Artemis reached for her breast pocket and prepared to take out her Advent Deck as well. "You asked for it." Artemis quipped, ready to whip out her Deck and transform into Kamen Rider Sage.

All of a sudden, an echoing ringing noise was heard. "Wait." Katie said, placing her Advent Deck back into her pocket.

"Giving up so soon?" Kim teased, preparing to press a button on her Wristwatch Kimmunicator.

Artemis stopped reaching for her Advent Deck and looked around as well. "Kim, I hear it too." The archer replied. She then looked back to Katie. "What's going on?"

"I swear, I've no idea what's going on." Katie replied, holding her hands up innocently.

At that moment, Gazelle Monsters started to jump out from windows. People screamed and yelled in horror as the endless amount of Monsters emerged. All of the Gazelles started to randomly attack people left and right with no indication that they would cease their attack.

Kim gasped as she saw a Gazelle Monster prepare to attack a mother and a child. She ran towards the Gazelle Monster, knocking it to the ground with a dropkick.

"Get out of here, hurry!" Kim yelled.

The mother and child started to run out before more Gazelle Monsters started to appear.

"Artemis to Cave, we have a situation going on at the Happy Harbor Shopping Centre!" Artemis yelled as she knocked aside a Gazelle. Katie did the same before Artemis continued to speak through her comlink. "We need backup, stat!"

"I'm there, Artemis!" Robin replied through the comlink. "Master Eubulon's sending Kit, Len, Pryce, Chris, Chance, Kase, Ian and Ron to the Mall to back you up, and I've contacted the League to come and help."

Artemis nodded. "Thanks, Robin!" she yelled back. "And I've got Kamen Rider Jaeger here too! She didn't summon the Mirror Monsters, but I'm taking her I'm after this is done."

"Not in your life!" Katie yelled, landing a punch on one of the Mirror Monsters.

Kim knocked aside one of the Mirror Monsters before using one of their spears to stab another one in the chest. She then pressed a button on her Wristwatch Kimmunicator, causing her Battlesuit to appear. The Battlesuit was white with lines of blue energy surging through it. Kim immediately ran into battle and continued to fight.

Soon, Batman, Wonder Woman and Superman arrived. "Is everyone out of here?" Wonder Woman asked Artemis and Kim.

"All the civilians are out of the area!" Kim exclaimed.

"Good." Batman replied bluntly. "We don't want anyone to get too suspicious about what's going on."

Batman threw many of his batarangs and landed punched and kicks at the Gazelles during his fight while Superman and Wonder Woman used their super strength to crush the skulls of the monsters. Batman was too engrossed in his fight that he did not notice several Gazelles advancing on him. The Gazelle, however, fell after a birdarang knocked him down.

"Need help?" Robin asked as he then ran in, catching his birdarang.

Batman smirked before getting back to the fight, Robin now joining him.

Robin and Batman were both back to back. Both of the former partners nodded knowingly and fought the Gazelles as a team. Superman blasted a few with his heat vision, burning them to death. Wonder Woman was fighting using all of her Amazonian strength.

Artemis blocked an attack from a Gazelle with a spear, being driven back. She then looked over to Kim. "I'm going to stop these guys at the source!" Artemis called out. "Think you can take care of things here with the others?"

Kim clashed with another Gazelle before kicking him away. "Count on me!" she exclaimed.

Artemis chuckled and punched aside a Gazelle, whipping her Advent Deck out and letting it glow to form her V-Buckle.

Katie did the same as she leapt over another one of the Gazelles, holding her Advent Deck out as well and letting the V-Buckle form.

"Kamen Rider!" Artemis yelled, sliding her Advent Deck in.

"Kamen Rider!" Katie called out as she placed her Advent Deck in too.

Both Artemis and Katie then transformed into Kamen Rider Sage and Kamen Rider Jaeger respectively. They unsheathed their Visors, destroying more of the Mirror Monsters before heading into Ventara.

Outside, Kit rode his bike until he got to a window. He mounted off of his bike and then placed his Advent Deck out. "Kamen Rider!" Kit yelled. He transformed into Kamen Rider Dragon Knight while heading in.

Len had arrived in another part of the Mall with Kase. "Kamen Rider!" they both yelled out, entering their transformations as they entered Ventara as well.

Chris and Ron then arrived with Pryce, Ian and Chance. "Let's do it!" Chris yelled out.

"Finally!" Chance exclaimed. "I've been waiting to fight."

The five Kamen Riders placed out their Advent Decks at the window. As soon as their V-Buckles formed, they placed their Decks to the side. "KAMEN RIDER!" They all exclaimed. They slid their Advent Decks into their Belts, and they started to spin. Orbs surrounded them all, allowing them to transform into Kamen Riders. As soon as their transformations were complete, they all entered Ventara.

Ventara…

Ten Advent Cycles appeared in a reflection of the Mall, all stopping to a halt as they formed a circle in front of them.

Each of the ten Kamen Rider started to emerge from their Advent Cycles, readying their respective Visors as they turned to see the Gazelles. "Where did they all come from?!" Katie exclaimed incredulously.

"If you didn't sent these guys, then that means someone else did!" Ron yelled.

"No time to quarrel, guys!" Len called out. "We need to stop these Mirror Monsters before more reach Earth."

Katie sighed as she then placed her Whip on her shoulder. "We'll call a truce for now, but when this is done, we go back to fighting."

"Better said than done." Kit remarked.

Kamen Rider Torque then took out two Advent Cards from his Deck. "These should do." He said, slotting one Card in.

LAUNCH VENT!

Two Shoulder-Mounted Cannons then appeared on Torque's shoulders before he slotted in the other card.

SHOOT VENT!

A large bazooka then appeared from the sky.

Chris chuckled and took out a Card. "Two can play that game." He quipped.

"Make that three." Pryce then said, taking out another Card.

"Four." Artemis quipped.

Chris slotted in his Card.

COPY VENT!

A copy of the Giga Launcher appeared in Kamen Rider Sting's hands before it also appeared in Kamen Rider Sage's Hands, as well as in Pryce's hands.

"What?!" Chance exclaimed. "No fair!"

"Way fair!" Artemis quipped. She then placed the Giga Launcher on her shoulder and shot a shell at most of the Gazelles, destroying them instantly.

"Whoo-hoo!" Chris yelled, his Evildiver soon arriving. Chris jumped on top of his Advent Beast and started to shoot as well.

"That's what I'm talking about!" Pryce exclaimed, summoning the same Advent Beast to mount on.

Len summoned the DarkWing and started to fly, slashing at all of the Gazelles before Ron ran in, slashing at more of the Gazelles with his Pek Kwar Visor.

Soon, all of the Riders were fighting with their own style, taking Gazelles down one by one and then twenty-five by twenty-five.

Katie lashed her Bounty Visor into the air, catching onto a support beam before using her Bounty Claws to brutally cut down more of the Gazelle Beasts.

Kit and Kase both used their Swords, slashing at every one of the Gazelles before Kamen Rider Dragon Knight slotted another Card into his Visor.

STRIKE VENT!

The DragClaw appeared on Kit's hand. Taking a step back, Kit shot a large blast of fire towards the Gazelles as the DragReder finished them off.

All of the Kamen Riders then formed a circle. More of the Gazelles had arrived, and they were pretty much outnumbered.

It was then that everyone took out the exact same Advent Card, slotting them into their Visors at the exact same time.

FINAL VENT!

FINAL VENT!

FINAL VENT!

FINAL VENT!

FINAL VENT!

FINAL VENT!

FINAL VENT!

FINAL VENT!

FINAL VENT!

FINAL VENT!

Kit circled his arms around each other as the DragReder circled around him.

Len leapt into the air as the DarkWing attached to his back.

Chris leapt onto the Evildiver.

Chance's Magnugiga appeared in front of him as he placed his Magna Visor into its back.

The VenoSnaker arrived as Pryce backflipped into the air.

Ian's Volcancer appeared behind him as Kamen Rider Incisor spun around in the air as a ball.

The BlancWing flew by, flapping its wings in front of the Gazelles towards Kase as she held her Wing Slasher.

Artemis leapt onto her Secretariat and started to aim her Bow at all of the Gazelles.

Ron spun around the Pek Kwar Visor before throwing it into the air.

Katie was soon lifted into the air and then thrown up as her DezPanther charged at the Gazelles.

Kit soon flew down, landing a flaming dropkick on all of the Gazelles.

Len landed a Spiral Kick on the Gazelles, crashing down on all of them.

Pryce landed a Bicycle Kick on each of the Gazelles.

Chance launched missiles and lasers from every part of the Magnugiga, all aimed towards the Gazelle Monsters.

Kase slashed the Gazelle Monsters as they made impact at her, now slashing all of the Monsters apart.

Ian crashed down onto the Gazelles, performing a cannonball on them.

Artemis dashed right at the Gazelles, shooting down at them before charging right through them.

Ron slammed his fist down to the ground, causing the Pek Kwar Visor to land on the ground as well, flattening all of the Gazelles like pancakes.

Katie charged down towards the Gazelles and slashed at them alongside her DezPanther, being able to cut them all to shreds and letting them all explode immediately upon impact.

Finally, everyone had completed their Final Vents. Each of them landed a respective Rider Kick, Rider Shooting, or Rider Cutting at the Gazelles, ending all of them at once.

Everyone soon got back up, all looking to each other. The Ten Kamen Riders let out a laugh before looking around. "We did it." Kit said calmly.

"We got them all." Artemis said with relief, seeing all of their Advent Beasts eat the energy of the destroyed Gazelle Monsters.

Katie chuckled before sighing. "This was fun, but I have to go now." She said.

Artemis looked to Katie as she walked back to the mirror. "Wait!" the archer called out.
