10 Deadliest Supervillain Teams
4. Brotherhood Of Mutants
As a rule, if a group in a comic has the word "Brotherhood" in it, chances are the people in it are up to no good. This golden comic rule is largely the fault of the Brotherhood of Evil Mutants, a team of superpowered villains led by Magneto, who united them due to their shared trait of being understandably furious at the way they were treated because of their mutations.
What would be less understandable, however, is the way that the Brotherhood would decide to deal with said treatment, in that their solution was to wipe out humanity itself.
But this would bring flocks of upset and alienated mutants to the team, all wishing to lash out at those who had ostracised them - making the Brotherhood of Mutant dangerous both in the powers of those within it, and in the destructive ideology it promoted.
