I'm thinking in subtly adding Kamen Riders in the Miraculous Ladybug series Obviously the two properties are not mine!

Years ago, a young man named Magnus came to live with his Uncle Enzo in a modern post-apocalypse city after what happened with the old capital. With the threat of hollows and Ethereals right on your doorstep, the desire of venturing into the hollows, hunting Ethereals and helping others was what he wanted the most. However due to his condition, Hypersensitive to Ether, he couldn't enter those zones without turn into an ethereal in less than ten seconds. However, with his intelligence, Enzo's mechanical skills and the blueprints left to him by someone important from his past, they created a system of armor that completely filtered out the ether and even give the wearer extraordinary abilities. Because of Magnus's desire to help, was decided to named it 'Desire Driver'. Everyone now knows him as New Eridu's hero, Hollow Rider Tycoon or... The Hollow Rider of New Eridu. 1°- Kamenrider (08/12/25) ((Note - I am not the owner of Kamen Rider, Zenless Zone Zero or any of the characters, the entire credit goes to the original creators.))

When Ben Tennyson discovers the Omni-Driver-a mysterious Spiral-tech relic that doesn't just transform him into aliens but fuses their memories and identities with his own-he becomes Kamen Rider Omni. But this isn't a fight to save the world. It's a fight to stay himself. Because across the multiverse, other Bens have fallen. Twisted Bens. Forgotten Bens. Broken Bens. And one... who chose to stop being Ben at all. Now, they're hunting him. Challenging him. Testing whether he can stay whole while wielding the impossible power of the Omni-Driver. Each alien he becomes adds to the Spiral-layering thoughts, instincts, fears not his own. Each battle chips away at who Ben is beneath the mask. As the Spiral tightens, old allies return. Ben 23, now Kamen Rider Nova, reckless but burning bright. Ben 10K, the hardened future warrior, now Kamen Rider Sentinel, armored in discipline and loss. And Gwen 10, reborn as Kamen Rider Wyrd, a mystic fusion of spell and steel. Together, they stand beside Ben... and against him, when they must. Because even united, they all know the truth Ben won't admit: The Omni-Driver is consuming him. Every alien form brings him closer to unraveling. And if he loses himself completely... There won't just be no Ben left. There'll be no one left to stop what he becomes.

Чотири світи - чотири королівства: Карáлест, Тéринн, Фаренéса і Валмáра - колись були поєднані дорогами Мандрівників, магів крові, що керували силою чотирьох стихій. Та зі зникненням Валмáри проходи було запечатано, а світи - розірвано й ізольовано. Пам'ять про Мандрівників майже зникла, зведена до тіней у старих легендах. Але давнє ніколи не зникає остаточно. Сліди Валмáри повертаються. І разом із ними - легенди, що знову починають жити.
