In the Megaman games, Mega Man is always being teleported to the Robot Master's levels, but what do we really know about the process? Is it a matter-energy conversion, or is Mega Man being converted into data and only that data is being transmitted to a new location? If so, what happens to the original Mega Man? Or, at the very least, what happens to his consciousness? Then again, what happens to his consciousness when he "dies" in a game? Is his consciousness automatically transmitted to a new body, which is them "beamed" in? I suppose, given that Mega Man really is just a robot, so his soul is just a computer program, these kinds of existential questions don't have quite the same impact they would if we were talking about human beings.
By the way, the title comes from a line in Galaxy Quest, and the opening line is something of an allusion to Back to the Future.
