- "To my mutant brothers and sisters out there, I say this: No more hiding. No more suffering. You have lived in the shadows in shame and fear for far too long. Come out. Join me. Fight together in a brotherhood of our kind. A new tomorrow, that starts today."
- ―Magneto
The Brotherhood of Mutants was a mutant terrorist organization fighting for mutant supremacy. It was founded by X-Men separatists and former members of the recently extinct Hellfire Club and led by Magneto.
History
1962
First Brotherhood team
The Brotherhood of Mutants was formed in 1962 by Magneto following the death of Sebastian Shaw during the Cuban Missile Crisis with the remnants of Shaw's Hellfire Club. Prior to its formation, Magneto was a founding member of the X-Men led by his friend Charles Xavier, but he defected due to differences in philosophy regarding human-mutant relations. The original team consisted of Magneto, Mystique, Riptide, Azazel, and Angel Salvadore, and, soon after, they staged a raid on the CIA's headquarters to release Emma Frost from her prison and recruit her into their ranks.
Azazel's autopsy report
X-Men: Days of Future Past Prologue
Azazel and Angel were killed by Project WideAwake operatives in July 1963, and Emma Frost was also killed between 1962 and 1973. They were all experimented on by Bolivar Trask.
X-Men
Brotherhood's second incarnation
Decades later, the Brotherhood consisted of Magneto, Mystique, Toad, and Sabretooth. They planned on using Rogue to power a Conversion Machine that would turn humans into mutants. In the resulting fight, Toad was electrocuted by Storm, Sabretooth was knocked out from the Statue of Liberty by Cyclops, and Magneto was defeated and incarcerated in a specialized Plastic Prison designed by William Stryker to negate his powers. After Mystique gets defeated by Wolverine she survives the battle and goes into hiding.
X2: X-Men United
Mystique helped Magneto escape from his plastic prison, and the two work together with the X-Men to stop Stryker's plan to initiate a mutant genocide. After foiling Stryker's plan, Magneto uses Stryker's Cerebro to try and kill all of the humans instead, but this plan is in turn foiled by the X-Men. Pyro betrays the X-Men and joins the Brotherhood with Magneto and Mystique while they escape in a helicopter.
X-Men: The Last Stand
Following the announcement by Worthington Labs of a supposed mutant cure, Magneto expands the Brotherhood with the inclusion of the Omegas to stop the unveiling, eventually leading to a battle at Alcatraz Island in which most of its members are either killed or de-powered. The Brotherhood was disbanded indefinitely after Magneto lost his powers.
