I have a few theorys about metroid prime 2. First of all, I think metroid prime is the result of genetic experiments with metroids and X parasites (from metroid fusion), because it has characteristics of both. Second, I think that the Ing are X parasites that have been mutated by phazon. The Ing and the X both have the ability to posses other creatures. For those of you who have'nt figured it out yet, Dark Samus is metroid prime. If you finished the first game with all the upgrades, you got to see the full ending where prime is still alive and is wearing a version of your suit that it copyed. My argument for it being a metroid/x hybrid goes somethig like this: In Metroid Fusion (MF) Samus gets infected by X. the X have the ability to copy their victims DNA and turn themselves into a clone of the victim. The SA/X (the name of the Samus clone) looked alot like Dark Samus except it was'nt black. plus, both Dark Samus and the SA/X contain Samus' DNA. another reason for my "Hybrid Theory" is that the X reproduce through asexxual division (they make an exact copy of themselves, like bacteria). Prime had a similar ability in MP. It could'nt make a copy of its self, but it could create other metroids.
I didn't make it!
well it seems a good theory, but the metroids are the predator of the X parasites. Metroids were originally created by an ancient civilisation on SR388, for peaceful energy production. This went wrong and the metroids wiped out the civilisation, and colonised the ruins left behind. When samus went to SR388 she wiped out all metroids, except for one, which she took to the ceres space station. Without the metroid the X parasites were suddenly the top predators on the planet, which is why samus got infected so quickly. Samus was injected with a vaccine, which was made from metroid DNA, the X parasites were killed almost instantly and samus was cured. This means that the DNA of the metroids is devistating to X parasites. Dark samus came around when Metroid Prime removed the phazon infection from samus's suit, which has some organic components. using the DNA it absorbed with the phazon suit, Dark Samus was formed. As for the Ing, they are symbiotic, and only use the creatures they infect as tools, where as the X parasites are parasitic, and absorb the prey, they move on to the next victims. Its true that they all show some similaritys, but they are all different, in their own ways. A final note to is that the X parasite are single minded and instinctive, where as Dark Samus has a direct vendetta against Samus (since samus kicked its ass several times:naughty: )
I rethought it, and you're right about most of that. But the Chozo were the ones who created the metroids to keep the x, which had nearly overrun SR388, in check. Read the instruction book that came with MF to see for your self.
