>>113234714>>113234688>>113234897What you have to realize about Roy is that when he introduced the term "retcon" for "retroactive continuity" (it was a fandom term first but he used it in his Invaders run) it had a completely different meaning than it does today.
"Retcon" originally meant "a story taking place seamlessly in between published stories", meaning that if you read an All-Star Squadron story you should be able to go seamlessly from that into the next 1940s issue of All-Star Comics with the JSA.
Now of course Roy was also the first to break this definition.Actually he wasn't, Stan and Jack were. When they restarted the Marvel U they explicitly stated that golden age Marvel comics weren't canon unless they were referenced. This was because Stan and jack preferred the blank slate and the right to retell and change any GA story they wanted. So for example they did the Tales of Suspense Cap run which basically retconned the Red Skull entirely. And Roy had to follow suit with this when he did Invaders, so he ignored or changed a LOT of GA stories for it.
With his DC work (which he was always a bigger fan of) he tried much more to stick to the published stuff, but even then he found himself changing things. For example, All-Star Comics issue 11 proved problematic. In "The JSA join the war on Japan" the GA creative team showed the JSA basically mopping the floor with the entire Pacific theatre, retaking territories that would be held by Japan for the entire war, and destroying most of their pacific fleet. Since this "could not" occur in a world where WW2 continued until 1945 with the nukes being needed, he rewrote ASC 11 to be a nightmare induced by Brain Wave.
But overall, he tried to stick close.
