Autobot Matrix of Leadership>All-spark. Considering the lore than what makes transformers what they are is their 'spark', the All-spark could be akin to their primordial ooze, but considering their non-organic nature, I suppose they can't just boink to procreate their species.
Though when Galvatron makes his inevitable appearance in the movies, I do hope that Leonard Nimoy voices him again. The 1986 movie rocks the socks. Except for that token pain in the ass human. PREPARE FOR EXTERMINATION! Their defenses are broken; let the slaughter begin!
And then there's the look on that one decepticon on the reflection of Prime's grill... *coughs* I had a cool uncle who used to babysit me a lot. >.>
As for the update, it's coming, but considering the, erm, enormity of what I want to do, it's taking a bit longer. Just to put it in perspective, this update will end immediately following the opening cinematic.
EDIT: Also, the Cube is probably a relic of the Quintessans, who created both the autobots and decepticons, who then promptly turned on their masters and whupped them good.
