User blog comment:Garfield 123/What Alien Species From Metroid Would Be the Largest Threat to Mankind in Today's World?/@comment-2015332-20101021050614/@comment-2015332-20101028032511

The funny thing about Metroids is that they would not be that effective as bioweapons. Everyone knows that the most dangerous things in the world cannot be seen. The X Parasite, even though it can be seen, would be quite effective at destroying populations. There is no way to destroy them without extremely powerful weaponry because we don't have any Metroids to make vaccines. They would be difficult, if not impossible, for the user to control, however. Btw, who would care about an infection if we all were already dead?
