TF X Anime/Manga

Optimus Prime: Before time began, there was the Cube. We know not where it comes from, only that it holds the power to create worlds and fill them... with life. That is how our race was born. For a time, we lived in harmony. But like all great power, some wanted it for good, others for evil. And so began the war. A war that ravaged our planet until it was consumed by death, and the Cube... was lost to the far reaches of space to a planet called: Earth. But we were already too late.
