This What If issue was broken into two sections: What If: Secret Wars? and What If: Runaways became the Young Avengers?.
I'm not even going to talk about the Runaways section because it is like pretty much every other Runaways story...not good. It's only saving grace is that it is short compared to the Doom story.
The main story features our favourite villain, Victor Von Doom. In this story, Doom maintains the Beyonder's powers and returns to Earth from Battleworld victorious.
We are given a small glimpse into Doom's past as he gradually climbs the power hierarchy, defeating anyone and everyone in his past. When all the smoke settles he realizes that despite all his intentions there is nothing left to rule.
This was a fantastic piece of storytelling. I highly recomend it to anyone with a remote interest in Doom.
