I can totally see it happen with Robot Masters, but not all of them obviously(For example Flash Man). first they would participate into those what you call them robot car tournaments where the cars are supposed to destroy each other, only this time mini Robot Masters are deployed, and a few decades later they will get implemented by the DARPA, or whatever mighty R&D company we would be dealing with then, to be unleashed on other robots.
I didn't consider time in itself, but I can definitely see someone trying to rebuild these favorite Robot Master of ours should someone still be able to remember Mega Man's franchise in a long, long future ahead(Or a short one?). Atleast ice and fire based ones. At the very least.
Oh and that video above is scary.
