11 Comic Book Characters Who Killed Their Loved Ones
10. Magneto
House of M famously flipped the world of Marvel Comics upside down, with an unstable, erratic Wanda Maximoff creating a new reality where mutants rule the world - in particular, it's Wanda's father Magneto who rules the roost, here.
While the main reasoning for Scarlet Witch doing all of this is to try to recreate her lost children, this new House of M landscape also makes the dreams come true of so many other characters. For instance, Spider-Man is married to Gwen Stacy, Steve Rogers is an aged military veteran, Carol Danvers' Captain Marvel is the USA's most beloved hero, and Wolverine had his long-lost memories returned.
It's in this use of Wolverine here, that the tale of House of M began to fully unravel.
Given how he is the only person with memories of how the world used to be, Logan embarks on a mission to convince others that this present-day landscape is not what world really is. And in doing so, one of the people who Weapon X appeals to, is Magneto.
As part of this revelation, the Master of Magnetism finds out that Quicksilver - his own son and the brother of Wanda - had manipulated Scarlet Witch into altering reality.
Shockingly, the incensed Magneto reacts to this by killing Pietro by raining down large chunks of steel onto him.
Reality would later be reset by Wanda, which in turn had Quicksilver was once again amongst the living, but the cold, hard truth is that Magneto willingly, purposefully killed his son before House of M was no more.
