On Earth, mutants are generally second class citizens...if their lucky. Abuse and persecution is common everywhere. Ordinary humans see mutants as either tools to be exploited or as a threat. Many do not see mutants as humans at all. The United States (and other nations) have made laws to protect mutants, but these laws are often ignored. When violence occurs, much like the old lynching's in the American South, the human perpetrators are rarely charged.
     Mutants on Earth are powerful, but also afraid. Like Bellasarian mutants, they are vastly outnumbered by their human cousins. Most mutants try to escape trouble by blending in and passing themselves off as baseline humans. Others are just too outwardly different to hide. Most (much to the disgust of the Bellasarians) tolerate human fear and abuse, exercising patience and hoping for the day when they'll be accepted. But there are those who can't fit into the mold. They don't have patience, and they won't hide any longer, and when pushed, they push back...hard! Although feared by humans and disapproved of by many mutants on Earth, these are just the type of young men wanted by the Bellasarians to replenish their own dangerously reduced adult male population.
