What If?
There were various What If issues that had Magneto as a key character:
- What if? ... "What if Magneto took over the U.S.A.?" - Following the death of Professor X, Cyclops, and Jean Grey at the hand of Cable, Magneto becomes dictator of the United States uniting the Freedom Force, the Morlocks, the Externals, Shadow King, the Nasty Boys, Fenris, the Savage Land Mutates, the Hellfire Club, and the Mutant Liberation Front. When he took over the White House, the president unleashed Sentinels which killed every mutant and non-mutant. Psylocke tried to warn Magneto about one Sentinel that carried a nuclear warhead, but it was too late. When Magneto destroyed the Sentinel, the nuclear warhead exploded killing him, Storm, Psylocke and every other mutant that was in the White House at the time. This was the Master of Magnetism's first starring role in the series, spinning out of Uncanny X-men #269.
- What if? ... "What if Legion killed Magneto?" - Magneto is the focus of this issue, through his merely absence in a diversion from the Legion Quest and Age of Apocalypse storylines.
- What if? ... "What if the Age of Apocalypse had not ended?" - Prominently features Magneto continuing his role as leader of the X-Men, continuing after the events shown in Age of Apocalypse.
- What if? ... "What if Magneto ruled all mutants?" - Magneto leads the remains of mutantkind, as they float through space on Asteroid M.
- What if? ... "What if Professor X and Magneto formed the X-Men together?" - In an alternate reality, Magneto and Xavier's confrontation with Baron Von Strucker did not end with Magneto leaving with Von Strucker's gold. Instead, he was convinced by Gabrielle Haller to let go of his hatred. Together, Magnus and Xavier formed the X-Men and were responsible for advancing the mutant cause and aiding world peace.
