Too bad the Metroids are almost as dangerous as the X.
Ya... but then again Metroids have a use in the medical field (Ex. The final battle in Super Metroid).
They're somekind of cure for the infections of x parasites too
Rai that's not exaqctly true, the cure is syntesized through their DNA, to cure the infection you need to become part Metroid :P
AMJZero, you're not exactly correct. THAT Metroid was trying to save it's "mother". It was the hatchling that Samus found and it thought Samus was it's mother. Thats why it stoped feeding on her and gave Samus the last of it's energy AND the energy it took from Mother Brain (the final weapon).
Its also stated in the opening Movie of super metroid (samus's logbook of when she gave the hatchling to the scientists)... However I forgot the exact quote at the time I posted last.
and of course the hatling was stolen by Ridley who had the pirates clone/feed it to get more Metroids and kept that original Metroid inside the base's defenses where it would be safe.
You die from either a flesh eating virus slowly consuming you while taking on your form or by having your SOUL sucked out and eaten by a giant, near indestructable parasite. Some choice...
