Unfortunately, as the Soviets advanced on the capital, Hitler and his clerks succeeded in opening a portal to a parallel universe. He took some of his highest ranking officers through, but was trapped on the opposite side when the Soviets stormed the lab.
There, he found a wasteland of techno-barbarians, remnants of a once great society that had spanned the stars.
He united several of these roving warrior bands, and in time conquered the globe. He named himself The Emperor of Man, and created from his own (now heavily modified) genetic template twenty super warriors he named Primarchs. These were scattered into space, but he used samples taken from each to clone massive armies, whom he dubbed Space Marines.
After an extensive campaign to retrieve the primarchs from where they had been tossed, he was betrayed by his favored primarch, Horus. after defeating Horus, and being mortally wounded, he was enshrined upon a Golden Throne originally designed to allow humanity to cross great distances in an eyeblink, now retrofitted to sustain his life-force and act as a beacon for all interstellar travel.
Explains a lot about the whole Xenophobia thing.
EDIT: I just read through and realized I used massive three times. In the same paragraph. I fail at grammar- and I know, I'm a terrible person. on a personal note, I hope he got some slow death from impalement over some big firey pit somewhere. EDIT EDIT: now I only use Massive once.
