CHEMY×STORY Hyrule [Kamen Rider Gotchard X Legend of Zelda]

A long time ago, during the establishment of Hyrule Kingdom, King Rauru and Queen Sonia heard interesting rumors about Alchemist, revealing the greatest creation of artificial lifeform it took on. They took a look at it and were in awe of the forms they had never been familiar with. Thus, The King allows the group of alchemists to create more artificial lifeforms around 101 to help them bring Order to a better world against evil, naming the artificial lifeform, Chemy. However, they learn when used by people with malice hearts, it turns Chemies into Malgam, an amalgamation of artificial lifeforms and malice from dark hearts. Because of this, they constructed a card, named Ride Chemy Card, to fight against said threat. Hopper1 & Steamliner were the first ones to be seal within the card as they created a belt as the first one was a human transform with fusion power of Hopper1 & Steamliner as blue train hopper, Kamen Rider Gotchard.

Now, it's been over a century since the Chemies were all sealed within their card as Zonai vanished after the death of Sonia and sacrificed from Rauru to seal Ganon away as the ancient technology later formed and left after the Ancient Hero with Master Sword & Descendent of Goddess with power to seal defeated Calamity. Now, in the new era after 10,000 years, it creates a separate timeline from the original timeline where a new hero outside of Hyrule from a different world came to Hyrule at a young age. And that kid was Minaru Ichinose, a destined hero to become Gotchard to save the world not just from darkness but to save all Chemies from malevolent beings and bring balance to the order of the world as he learns what it takes to be a hero like them. But, he isn't the only one that lands into a different world.
