This is why we don't have nice things
Except that now they are also posting bits of Dark Avengers #176, showing how the Thunderbolts, in the far past for irrelevant reasons, happen to rescue Doom. The Thunderbolts. Rescue. Doom. And he of course betrays them for their time machine, and that's how Doom survived that thing.
No. Nope. Nooooooope. No-no. No chance. Nah. I refuse to acknowledge that Marvel just retconned one of Doom's Peak Doom moments into little more than outrageously good luck. It's worse than the time DC retconned Hal Jordan's completely understandable grief (together with maybe completely understandable plans) and subsequent one-man blitzkrieg against the Crops and grim semi-godhood into "possession by weird cosmic entity," rendering meaningless what had been a psychologically and narratively *interesting* event. Mostly because I'm a gazillon times more interested in Doom than in Hal and, to borrow a 2016 vernacular we'll never use again, the eons-long Big Bang-sized dumpster fire that is everything the Guardian have tried to do, ever.
