everyone I know it's been a long time and at one point I thought of quit writing as I was not getting any idea to make a crossover as crossovers are my favorite kind of story. But then I stated to visit my childhood shows and cartoons when I saw some of the power scaling from some of the shows like Adventure time, Doraemon and ben 10 etc , I realize just how overpowered some of those shows were I guess I never paid that much as i was a kid back then. But now I realize some of those character could solo most of the anime verse without even blinking.
After seeing these I decided to make a story with a crossover between them and I started to do power scaling of all my old shows these includes power rangers, beyblade, adventure time and more, well while I was making a power scaling for power ranger I come to know that power ranger are just a knock-off version of original Japanese show of super sentai and those guys are way powerfull then power ranger then I started watching them a little after that I get to know about kamen riders from one of crossover movie and let me tell all those who have no idea about kamen rider these guys are OP AS HELL!!!! .
The weakest of kamen rider are walking nukes, even mid- tiers kamen riders can destroy worlds with a kick, oh and here 'world' means a reality and high tiers are straight up GODS who exists outside of the entire Kamen rider multiverse so even if someone somehow erase the entire kamen rider franchise they will still be unaffected and lastly strongest of them all Ohma Zio who have the power of every kamen rider in existence "The demon king of time", I can go on about kamen riders for rest of the day because I have binged watched the entire series from kugga to Revice but in my opinion you should watch it if you haven't.
