Brotherhood of Evil
The Empire or The Syndicate. Instead, they prefer to give themselves a feeling of unity in their nefarious and evil purposes. Calling yourselves "The Brotherhood" doesn't sound that evil, but nevertheless it seems to be a popular name among evildoers in fiction. Though the name indicates an organization of equals, there still tends to be one "big brother" in charge regardless. The Brotherhood of Evil may function like The Mafia, or as a secret society with shadowy rituals and complex codes of honor, and are much less likely to invoke We Have Reserves on their "brothers" unless their sinister leader is just using them for his own purposes. If they're Card Carrying Villains, they might put a "Dark" or "Evil" in their name just to be clear that they're not the good kind of brotherhood.
- The Brotherhood of Evil Mutants, Magneto's supporters in the X-Men comics, which keeps the "evil" in its name despite often having sympathetic motives.

- Played with in the Fallout series with the Brotherhood of Steel. They're not evil, per se, but they've made many enemies due to their aggressive hoarding of pre-war technology, and have been known to murder people to preserve their secrecy. On the other hand, they have wiped out troublesome raider groups such as the Vipers, and have played a major role in the defeats of the Enclave and the Super Mutants.
