Kamen Rider: Cosmic Catastrophe

Lin Xuan transmigrates into the Kamen Rider Zi-O world, where he is bound to a Space-Time Guardian System and gains the power of Dark Decade. He can use the powers of Kamen Riders from the Showa, Heisei, and even Reiwa eras.

But Lin Xuan soon discovers that all the Kamen Rider worlds, Ultraman worlds, Armor Hero worlds, and many other tokusatsu worlds have been crammed into a single solar system!

And somehow, this solar system contains over ten thousand Earths!

Even worse, Lin Xuan is chosen by the System and must become a savior. Otherwise, once all the tokusatsu universes merge, every universe containing tokusatsu elements will be destroyed!
