The above image comes from the official Japanese Metroid webpage, but is shrouded in mystery as to what it could actually mean. GoNintendo suspects it could be an online manga or story, perhaps not unlike the one which told the tale of Samus’ origin.
According to a translation from WiiZone, “it seems certain that he will be tied to the history of Metroid lived from the perspective of the Space Pirates … interesting, eeh?”
No one is sure yet just what it will be, with even the speculation of a new game being bandied about lightly. If it turns out to be some sort of online story or manga, though, I can only hope that Nintendo might bring it here. I wonder what it would take to convince them?
