More like...a Xenomorph had a threesome with Metal Gear Ray and Laughing Octopus and this is what resulted.
And of course, by threesome, I mean, the Xenomorph facehugged and inseminated Laughing Octopus:http://www.vgcats.com/comics/?strip_id=108. Then somehow grafted a Ray unto itself. Or you can substitute Laughing Octopus for General Grievous.
