Brotherhood of Mutants

The Brotherhood of Mutants (originally known as the Brotherhood of Evil Mutants) is a fictional group of mutants appearing in American comic books published by Marvel Comics. The Brotherhood are among the chief adversaries of the X-Men. While the group's roster and ideology have varied from incarnation to incarnation, most versions of the Brotherhood are generally founded and led by the mutant Magneto as a supervillain team or mutant supremacy organization that uses extreme methods to fight human prejudice.

Unlike the X-Men, who believe that humans and mutants can coexist peacefully, the Brotherhood's members generally view humanity as an inferior, close-minded species that will never accept mutants out of fear of their powers. Among the mutants who are frequently depicted as members of the Brotherhood are Mystique, Toad, Blob, Pyro, Mastermind, Avalanche, Quicksilver, and Scarlet Witch.

The original Brotherhood of Mutants was depicted as Magneto's primary allies in his early battles with the X-Men in comics published in the 1960s. This Brotherhood was ultimately disbanded, with Quicksilver and Scarlet Witch going on to become members of the Avengers. In 1981, the Brotherhood of Mutants was revived under the leadership of Mystique, while the group's most visible incarnation during the early 1990s was led by Toad.

Outside of comics, the Brotherhood of Mutants has appeared in several animated series and video games featuring the X-Men, as well as the X-Men film series.
