To prevent the Germans being at the end of the stick for everything my Fascists (or one of the Bad guy factions) will be more like the evil twin version of the Federation; Culturally ambiguous albeit highly efficient in causing trouble! So Ockmans suggestion is likely where its at. Though I do have a force of Highly advanced Germanic Neo-Pagans in the works where AndrewBs Reich suggestions are tempting...
However Germans do sort of feature: The Vor Konglomerate
The Vor Konglomerate was created post Corporate war, with the intention of unifying numerous Germanic business colonies into a single entity that would comply with laws laid down by the victorious Federation. Eventually the Vor transcended it's corporate identity and became a fully fledged Democratic state that championed a healthy balance between the generation of profits and care for it's work force. Overtime as the Federation retracted and abandoned all but it's most loyal members, the Vor stepped up and became a major power in the Human Sphere. Ushering in a century long era known as the Pax Germanica to its neighbors the Vor developed a strong Alliance with other powers, most of which (though not all) had strong ties to the now mythical Continent of Europe on Earth.
Unfortunately the Europa Koalition was reasonably short lived, though it's existence ultimately rescued humanity from a few Alien incursions, the A.I Revolt and the rise of the UCRS, generally its members could not achieve the level of cooperation needed to make it last. Nevertheless the Vor Konglomerate emerged the most powerful military and economic power of the Koalition and is now arguably one of the 8 great powers within the Human Sphere.
These are a sort of hard nosed 'neutral good' force, made up completely of GZG figures. I did a pretty quick job painting these guys up (I don't spend much time on many of my 15s, but this was definitely the most break neck speed I have done).
At some point I'm going to have to get some scenery together and take some proper photos...
