Sorry for bumping this old topic but I would feel like such a crappy metroid fan if I didn't say this. That comic is canon. Yes. It is. Nintendo considers it canon. It is a japanese E-manga (a flash comic) that can be found here.
It was promptly translated by the following.
Anyway for those worried about the legality of altering it. I wouldn't be too concerned. If I remember right a Nintendo employee referenced it during a interview. So it would seem Nintendo knows about it and quite frankly doesn't care...
