8 Most Brutal Things Magneto Has Ever Done
2. Snapped Professor X's Neck - Ultimatum
If you're looking for a comic book tale that fully embraces Magneto as a murderous unhinged tyrant, you need look no further than Ultimatum.
In that 2009 Ultimate Marvel miniseries from writer Jeph Loeb and artist David Finch, readers are greeted by a Magneto who is grieving the loss of his children, Quicksilver and Scarlet Witch. Doing what any bonkers bad guy would do, the Master of Magnetism decides to take his own personal pain out on the entire world.
Having stolen Mjolnir from Thor (well, kind of... and maybe with a Doctor Doom assist), Magneto was unstoppable here.
Killing millions of the human race, this uber-rogue turns up at Xavier's Institute for Gifted Children to confront his on-off BFF. But after Professor X compares Magneto and his skewed viewpoint to Osama bin Laden, Pol Pot, and Adolf Hitler, that's enough to push Magneto even further over the edge - to the point that he snaps his long-time friend's neck.
While death is rarely a permanent fixture in comic books, the death of Charles Xavier did indeed remain permanent. Then again, that could well be down to the fact that the Ultimate Marvel imprint was soon brought to an end and relaunched as Ultimate Comics.
