Erik Magnus Lensherr
Magneto was born Max Eisenhardt sometime in the late 1920s to a middle-class German-Jewish family. Surviving discrimination and hardship during the Nazi rise to power, the passing of the Nuremberg Laws in 1935, and Kristallnacht, Max and his family fled to Poland where they were captured during the German invasion of Poland and sent to the Warsaw Ghetto. His mother, father, and sister were executed and buried in a mass grave, but Max survived, possibly due to the manifestation of his mutant powers. Magneto's experiences surviving Nazi Germany, Auschwitz, and Vinnytsia would shape his outlook on the situation that mutants face in the Marvel Universe. Determined to keep such atrocities from ever being committed against mutantkind, he is willing to use deadly force to protect mutants. He would believe that mutants ('Homo superior') will become the dominant life form on the planet and would set about either creating a homeland on Earth where mutants could live peacefully, or conquering and enslaving humanity in the name of mutantkind.
During Civil War II, Magneto fought to stop Ulysses and predictive justice, and most recently battled against the altered Captain America and his Secret Empire.
