An unlikely group of part-time mercenaries suddenly found themselves acquiring the powers of past Kamen Riders with a mission to aid the World of the Shinobi against a bigger threat than Ohma Zi-O himself. (A/N: This is my take on Senran Kagura: Rider Generations by Bravekabuto58.)

Following the destruction of Remnant by the Brother Gods, Jaune Arc, a soul lost to the war, found himself resurrected by an entity known as Omnius, with a simple task: Save worlds beyond your own. Granted with the powers of Kamen Riders, Jaune, now with a renewed purpose, began a new journey across the multiverse, using the powers of the Kamen Riders to save sentient life across the Multiverse. A/N: I do not own RWBY, Kamen Rider or any of the characters used here except for any created OCs.

Planet Earth has found itself under invasion since the year 2012 by a species of aliens known as Nova. Through their ability of Freezing, they made all military counterattacks worthless. This led to the creation of Pandora, young women who undergo genetic modification and training to gain strength and speed to combat these monsters with special Volt Weapons. They are aided by Limiters, young men who can produce their own Freezing Fields to nullify the Freezing Field of Nova, allowing their Pandora partners to dispatch the alien invaders. However earth is under threat from another Alien threat, the Worms, a species that crash landed on earth via a meteorite roughly a year ago. The technology company ZECT has been preparing for their arrival for decades. Training special Limiters to combat these new aliens, alongside providing a new form of support to Pandoras. One of these agents is sent to West Genetics with one goal in mind. Guide humanity down the Path of Heaven to a brighter future! Freezing belongs to Lim Dall-Young and Funimation, Kamen Rider belongs to Toei, I own my OCs.

When a new generation of heroes forms under the watchful eyes of the Justice League, they believe their greatest enemies will be supervillains, metahumans, and alien invaders. Unknown to them, another war has already been raging in the shadows for years. Hidden among humanity are the Worms-alien lifeforms capable of perfectly mimicking humans and moving at impossible speeds through a phenomenon known as Clock Up. To combat this secret threat, the clandestine organization ZECT has fought an endless war beyond the knowledge of the world's greatest heroes. Standing at the center of that war is a lone warrior. A man who walks the path of heaven. Souji Tendou. Known as Kamen Rider Kabuto, Tendou has defeated countless Worms while following his own ideals, never seeking recognition or praise. When Worm activity suddenly begins to spread throughout the DC Universe, his investigation leads him to the newly formed covert team known as Young Justice. During their very first mission, Robin, Aqualad, Kid Flash, Superboy, and Miss Martian unknowingly become targets of a Worm conspiracy. Before disaster can strike, an unseen crimson warrior saves them from the shadows, disappearing before anyone realizes they were ever in danger. To the Team, he becomes an urban legend. To the Justice League, he is an unidentified vigilante possessing technology beyond anything on Earth. To the Worms, he is their greatest nightmare. As hidden battles unfold behind every mission, Young Justice slowly uncovers fragments of a secret war that has existed for decades. Along the way, they encounter mysterious Riders, advanced ZECT technology, Hyper Zecters, Native Worms, and enemies capable of manipulating time itself. While the heroes strive to become legends in the light, one man continues to protect the world from the darkness without asking for thanks or recognition. Because true heroes do not fight for fame. They fight because someone has to. And as the conflict between humanity and the Worms.

The world of DC has always been protected by its greatest heroes. The Justice League defends Earth from cosmic invasions, alien conquerors, ancient gods, and reality ending crises. The Young Justice team protects the next generation while growing into legends of their own. The Titans, Justice Society, Doom Patrol, Birds of Prey, Green Lantern Corps, and countless independent heroes ensure that no threat goes unanswered.For decades, they believed they had seen every kind of evil.They were wrong.Without warning, mysterious monsters begin appearing across the globe. Some resemble mutated insects.Others are supernatural horrors.Some are biomechanical weapons.Others can disguise themselves perfectly as humans.No database recognizes them.No magical archive contains their names.Even the Guardians of the Universe, the Lords of Order, New Genesis, and Apokolips have no record of these creatures.Whenever one of these monsters appears.A lone armored warrior suddenly arrives.A masked hero.A Kamen Rider. Before anyone can question them, the Rider transforms, defeats the monster using powers unlike anything on Earth, and disappears without introducing themselves.No interviews.No alliances.No explanations.Only one battle then gone.Every Rider seems to come from a different origin.One fights with ancient spirits.Another uses cards.Another commands trains through time.Some wield magic.Some use science.Others harness memories, myths, space exploration, video games, evolution, artificial intelligence, or the power of human dreams.The strangest part No Rider has ever met another Rider.Each battle feels like a completely separate story.As if every hero belongs to a different world.For ten mysterious incidents, the heroes of DC can only watch from the shadows as these unknown champions save countless lives before vanishing once more.Only after the eleventh incident does the Justice League finally realize the truth.These aren't isolated events.

A mysterious dimensional catastrophe shatters reality itself. When the dust settles, the students of U.A. High's Class 1-A and Class 1-B find themselves stranded in a world completely unlike their own. In this new reality, heroes are not celebrities. There are no hero rankings. No hero agencies. No sponsorships. No fame. No paychecks. Instead, the people place their hopes in a different kind of hero. The legendary masked warriors known as the Kamen Riders. Living alongside their teachers, Eri, and All Might, the students soon discover that every generation of Riders still protects humanity from darkness. From the courage of Takeshi Hongo and the Showa Riders... To the determination of Yusuke Godai and the Heisei era... To the dreams and sacrifices of the Reiwa Riders... The students of U.A. will learn that being a hero isn't about popularity or recognition. It's about protecting people even when nobody is watching. As villains from both worlds begin to emerge and reality itself starts to collapse, Class 1-A and Class 1-B must train under the greatest heroes in history. Can the future heroes of U.A. learn the true meaning of justice? Or will the collision of worlds destroy everything they hold dear? The answer lies in the legacy of the Kamen Riders.
