Kamen Rider Ronin-He who wanders...

Scenario 14: Backstory...

Martian Manhunter explained to Batman what and who Evol is...

Martian Manhunter: "Evol was an alien that came from the now-extinct Blood Tribe, he had come to Mars with the Pandora Box as it was called and nearly succeeded in opening the weapon that could cause the mass destruction of the entirety of Mars..."

Miss Martian: "He also held the title of Kamen Rider in our world, though we are very confused about how he could be called something Human called as heroic..."

Martian Manhunter: "Which is why we are cautious about Earth's heroes when they share the same title..."

Batman: "Kamen Riders are Masked Riders when directly translated from Japanese..."

Zeta-Tube: Katana! 37!

The Transporter announced as the Japanese Hero that wielded a Katana arrived...

Katana: "Yes...that's right..."

Batman: "Could you explain what Kamen Riders were..."

Katana: "Certainly..."

Katana: "Kamen Riders were created when an Evil Syndicate, Dai-Shocker tried to weaponize a human..."

Batman: "And it worked...?"

Katana: "It did, at the time the person that was experimented by the organization became a cyborg, who could summon armor that enhanced his strength, agility, and speed accompanied by a bike created especially for him..."

Miss Martian: "What happened?"

Katana: "But he escaped before they could brainwash him into a personal puppet..."

Katana: "The man became the First Kamen Rider and the Kamen Riders that followed would join his crusade against Dai-Shocker..."

Batman: "Dai-Shocker...?"

Katana: "It is the same cliched Evil Organization that is very similar to Cadmus..."

Batman: "How come we've never heard of them?"

Katana: "The Kamen Riders are vigilantes like us and they have some relation to the local government and the enemies they faced can only be defeated by them, so normal police couldn't help at all..."

Katana: "They were no reports in years after they defeated Dai-Shocker..."

Katana: "Until another person used the mantle..."

Batman: "Who is it?"

Katana: "From what I could dug up, the person was Yusuke Godai, a archaeologist who assisted in finding the tomb of Kuuga..."

Batman: "Kuuga?"

Katana: "An ancient warrior who Protected Humans before Modern Civiliization came to be..."

Miss Martian: "So the Archaeologist took the mantle and became the warrior...?"

Katana: "Yes and he became the started of a whole new generation of Kamen Riders..."

Martian Manhunter: "How peculiar..."

Batman: "This does not explain how Jack has the powers of a homicidal alien...!"

Katana: "I'm getting to that..."

Katana: "Evol was last seen when an interdimensional conflict happened and an alternate version of Japan experienced its mass destruction..."

Katana: "This was further explained how a terrorist organization formed and infiltrated the government, then stole the necessary data and materials to make their own Rider System..."

Katana: "After a few days the Terrorist organization was destroyed and the Riders were not seen until a concentrated amount of energy was detected near a Japanese school and abnormal humanoid monsters..."

Katana: "There were witness reports of oddly shaped watches that looked like what young Jack uses to transform..."

Katana: "More importantly there were people who saw watches that beared multiple different faces..."

Katana: "So far in this century a Kamen Rider has protected humanity for a year before the Justice League was even born..."

Batman: "Could we contact any of the previous Kamen Riders, considering that we need a person who could give us a full overview of Ronin's abilities...?"

Katana: "We could do that, but there are many other surviving Riders and there are some who are under the radar..."

Batman: "Are there any Previous Mantle holders that have a connection to the Government?"

Katana: "There are, but there is only one active Kamen Rider that has strong ties to the government..."

Batman: "Then we should contact him to teach Ronin what he can and can't do..."

Katana: "The ones that were summoned by him, are still somewhat active..."

Batman: "Good, because we need all the help we can get..."
