Originally posted by basiliskWhat a terribly myopic and ill-informed statement. Those stories were not retconned because of Thanos' failures...they were retconned because the writers grossly mishandled the character and reverted him back to 70s mode as a two-dimensional, universe conquering brute...when that was not his MO at the time.
Maybe one day some writer will retcon this in the same way Starlin retcons all of Thanos' failures as soon as he sees them.
BTW, Thanos beats Doom almost every single time.
