Kang is getting plenty of focus these days in Marvel comics but Doom is certainly not getting shoved to the side. The Doom Above All variant has been causing multiversal mayhem in the Avengers series for over a year now! Theories on his real agenda? I suspect at the end of that storyline, 616 Doom may be the sole remaining Victor Von Doom in the multiverse since DAA has been killing or enslaving all the others. I also hope the reason the 616 universe is the last one on his list is because 616 is still considered the "prime universe" that formed the foundation for all the others after Hickman's Secret Wars series. Maybe only 616 Doom can defeat DAA because of his prior role as God Emperor. I always liked the idea of the main Marvel Comics universe we are watching being uniquely different (the "Prime Universe"), because simply being the 616th out of potentially millions diminishes its importance relative to the others.
