User blog comment:Garfield 123/What Alien Species From Metroid Would Be the Largest Threat to Mankind in Today's World?/@comment-1741964-20101020040115

Yep. I'm pretty sure that the Doc( Who even then eventually gets Thingified) ran a simulation on his comp of what would happen if "The Thing" ever got outside of Antartica....TOTAL assimilation of Earth within TWO years. I caan very much imagine this happening with the X. Also another threat POSSIBLY even bigger than the X if they can reproduce as fast as the X, the Ing. It was stated by U-Mos that the Ing were very much disirable about finding a way to escape Aether and counquer other planets and races, even Earth. Imagine the Ing who unlike the X can turn even non-organic machines against the human race and can use the fact that the body they use isn't just a copy but the actual person being forced against their will to commit genocide and the family and friends that will take extreme mental anguish from this. Again I find the X and the Ing to be the most frighteningly dangerous lifeforms to anything in the galaxy. period. Perhaps the only thing that comes close are unfreezable metroids and Phazon.
