Mega Man: Bettle Network takes place in an alternate timeline. It has nothing to do with the original Mega Man timeline. It's simply a retelling with the Mega Man characters we're all familiar with however they've all been given a bit of a different look to them and they all exist as NET Nabbies inside of cyberspace. DenTech city is designed with vurtually complete automation in mind and the NET Nabbies essentially run everything who are in turn, controlled by their real life counterparts. I don't nearly know enough about this Mega Man story to give you full details as I've only seen...maybe one season's worth. But I do know that later on that eventually Lance and his NET Nabbie; Mega Man can actually merge with the help of a digital cyber-dome that is programmed to encase a building or small section of the city itself. and also Lance's grandfather is non-other then Dr. Thomas Light. He looks just like the original Thomas Light but I don't know if he still uses that same name in Battle Network.
