Here's the retcon in the guide that one anon talked about. Last few paragraphs.
>>92056796>We never got to see Thanos in the Cancerverse did we? But he should have been a dead statue if the Cancerverse's Death of Captain Marvel's events went the same as 616's up to a point.No, we never saw the cancerverse version of Thanos. Just his destroyed ship.
And we have no idea how events played out in that universe. They easily could have fixed him during their many angled transition. After all, nothing dies.
>>92055078See, I've sort of come to accept what happened. Death came to the cancerverse and killed Mar-Vell, yes. But she didn't stick around. She had to go back to her own universe, and she was shown abandoning Thanos there.
Still not sure why the universe didn't die, but I guess with Death gone it stabilized itself.
