WARNING: This article contains spoilers for X-Men Blue #31 by Cullen Bunn, Jorge Molina, Matt Milla and VC's Joe Caramagna, on sale now.
One character Cullen Bunn has spent significant time writing during his tenure at Marvel Comics is the Master of Magnetism, Magneto. Bunn first began chronicling Erik Lehnsherr's adventures in his self-titled solo series in 2014, which saw him go on a one-man crusade to protect the mutant race through any means necessary.
Bunn next took Magneto to Uncanny X-Men in 2015, where he led an outlaw team of X-Men consisting of Psylocke, Sabretooth, Monet St. Croix and Archangel. Finally, after faking his own death, Bunn had Magneto reappear as the secret mentor of the original, time-displaced members of X-Men Blue.
Though Magneto has tried to walk on the side of the angels, his violent, vengeful streak never truly went away. All that was needed was a reason (and a person) for Magneto to focus his rage upon. As we saw X-Men Blue #31, that person is Magneto's former teammate, Emma Frost.
The Real Magneto
During the Mothervine story arc in X-Men Blue #23-28, Magneto was forced to kill innocent mutants under the virus' control. Emma Frost and Havok, who was still inverted from the 2014 AXIS event, worked alongside Miss Sinister and Bastion to use Mothervine to alter the course of mutantkind in the Marvel Universe.
After forcing his hand, Magneto is now out for revenge, targeting Emma Frost first. However, the issue begins in the past with a meeting between Jean Grey and Erik. The two met in person so Jean could read Magneto's mind and properly vet him before agreeing to work together. Jean was taken back to Erik's youth, where he lived as a young boy named Max Eisenhardt, trapped in a Jewish concentration camp.
It's here where Magneto relives the moment that made him the person he is today -- the moment that filled him with so much hate and fear. But as Herr Hitzig notes, it's the real Magneto Jean should worry about. The Magneto with his true darkness and secrets buried under the surface. No matter the good he tries to do, the dark side of Magneto inevitably returns.
With Magneto's motivations made abundantly clear, he now sets his sights on his the White Queen of the Hellfire Club.
