In the comics
Originally Magneto's real name was Erik Magnus Lehnsheer. This was later retconned in the 2008 mini-series Magneto Testament where it was revealed that his name was Max Eisenhardt and that Erik Magnus Lehnsheer was just an alias.
During World War II the Nazis captured Max Eisenhardt and he was sent to a concentration camp in Auschwitz, Poland. While there Max reunited with a Romani girl named Magda, who he had fallen in love with years earlier. Max and Magda escaped Auschwitz during the Birkenau revolt of October 7, 1944.
Max Eisenhardt and Magda then moved to the Ukraine where they had a daughter named Anya. Around this time Max began using the alias Erik Magnus Lehnsheer. An angry mob burnt down their home and Anya died in the fire. Magnus' magnetic powers then manifested and he used them to kill the mob. Magda then left Eric horrified by what she saw.
Magnus then took the identity of Magneto and attempted to destroy or enslave the human race. However, Magneto was opposed by his former friend, Charles Xavier and the X-Men.
In more recent years it has been revealed that Magneto actually isn't Quicksilver and Scarlet Witch's father.
- Magneto was voiced by David Hemblen in X-Men: The Animated Series.
- Bryan Singer offered Hemblen the role of Magneto in the first X-Men movie but had to turn down the role because of scheduling conflicts with the television series, Earth: Final Conflict. The part of Magneto ended up going to Sir Ian McKellen.
- When casting Magneto for X-Men: The Animated Series the creators of the series had in mind a voice that sounded like John Vernon and an evil version of Charlton Heston.
- On X-Men: The Animated Series the sound effect for Magneto's magnetic powers was the same sound effect used for the Klingon's cloaking device on Star Trek III: The Search for Spock.
- Unlike the comics in X-Men: The Animated Series, Magneto's helmet could not protect his mind from Professor Xavier's telepathic powers.
- Magneto was originally going to be the main villain in the fourth part of the Secret Wars episode   . Magneto was then written out of the episode and replaced with Mister Sinister. Eventually the Secret Wars was shortened to three episodes and neither Magneto or Mister Sinister appeared.
