Since we have categories for corporations and families, maybe we could make one for countries and empires? What you guys think?
Races, I think.
Imperialists would work, as it would show that the entire nation is not evil.. rather the ruling regime.
Imperialists = regimes that favor aggressive expansion of their territories, often in defiance of established codes of war or humanitarian standards - they are often seen as "rogue states" but some have become highly successful conquerors and dominated entire star-systems.. these empires tend to be ruled either by dystopian governments (such as Big Brother) or a single, all-powerful dictator (such as Emperor Palpatine).
Ok, you'll see, I know I deciced to work alone in this wiki but I have received this message and I can't avoid to warn you about something.
Time ago this wiki had a category similar to the one you wrote in this thread but in singular; http://villains.wikia.com/wiki/Category:Imperialist And, as you can see in the elink, it was deleted because it was too close to "Evil Ruler" (currently merged into "Tyrants") and "Warmonger" (Currently merged into "Mongers").
The case is that we already have "Oppressors".
What do you think?
