The year is 20XX. Reploids - thinking robots based on the design of 'Megaman X' - work side by side with humans in relative harmony. Rogue reploids, which are prone to becoming violent for no reason, are generally few and far between; however, an abnormal rise in 'rogue' activity has now swept the city and only two elite Maverick Hunters can save the day - the dynamic duo, X and Zero! As their investigation continues and rogue activity increases, X and Zero can't help but feel they are being deliberately misled. With time running out and rogue reploids on the verge of destroying the city, can our heroes track down and thwart the villain before it is too late?
In a dark future, the world is in ruin and everything is slowly crumbling away into dust. Humanity is almost extinct, while robots desperately seek out new parts to replace their rusting bodies. Their only hope for survival is to devour the one known as Casshern… or so they believe. Meanwhile, Casshern himself has lost all memory of his past. Why are these robots attacking him? Did he really kill the one known as Luna; the Sun that was called Moon? And why is he, alone, unaffected and undamaged by the ruin?
MegaMan X and Casshern Sins are quite similar even though their stories are different. First off, both of them have a cyborg protagonist who is designed for fighting. (Fighting styles are different though) Secondly, both series feature a world in which cyborgs live alongside with humans, almost as equals. It also seems that the human population has decreased in both of them.
Character desing is also something worth noting, since the main characters (X and Casshern) look very much alike.
