OK. I know there are threads for Unicron, but I've had it! I'm tired of fanboys begging for Unicron, and saying things like, "He could work on screen." He can't! Get it though your head. He's just too frickin' big! Here's an example of size comparison. Let's say they make Unicron the same size as the moon. We won't even go to full planet size. The moon is 3,478,800 meters across, or 3,478,800 meters "tall". Optimus Prime is 8.53 meters tall. That means that the moon is 407,832 times taller than Optimus Prime. To put this in perspective, the average human 1.75 meters tall, so something 407,832 times smaller would only be, well, microscopic. See, a flea is about 1.5 millimeters tall (about 1148th the height of a human), and the average human can't see it unless he's really looking for it. Now, imagine how small something would be if it was 407,832nd the size of a human. You'd need an electron microscope to even think about seeing it. Now, who's gonna tell me that Unicron could still share the screen with the Transformers?
