7 Comics Characters Who Have Killed Thor
2. Rogue
What If? #66 saw a particularly unusual event, even by the comic's usual speculatory standards.
In it, Rogue uses her powers to absorb Thor's abilities - taking his lightning powers, his super-strength, and crucially, his ability to wield Mjolnir, which naturally means that Rogue then gains the title of being Thor, as the superhero alias belongs to whoever holds the hammer.
Whilst Rogue doesn't technically kill Thor, she does absorb him into her psyche, only for him to seemingly remove himself from existence when he claims she is now the 'true Thor'. Even if she hadn't accidentally removed him from existence, Rogue still completely takes over Thor's life, with Odin claiming that he has 'lost a son...and gained a daughter'.
It's a cool story - and a novel idea - but one that also makes you feel more than a little sorry for the actual Thor. It takes his dad a couple of pages before he totally forgets his son is now dead, and something about that just makes you feel bad, even if Odin wasn't winning any awards for being a good day in the first place.
