8.) Cerberus (Mass Effect)
Cerberus might not be a company per se, but they do have a significant number of employees so I think it counts. Don't understimate this organization as a simple pro-human advocacy group because they are far more sinister than that. In fact, they have no qualms about killing other aliens to further their human centric agenda. The irony is that they aren't also opposed to killing their own kind for the good of humanity. Perhaps their definition of humanity pertains to anyone who sides with them?
