So one huge battle?
I can see this coming down to the two MU characters by a slim margin.
After that, by an even slimmer margin, and tbh a coin toss by me, Wonderman eeks out the win.
In a fight with 3 flyers, AM is at a disadvantage.
Any of the 3, while not likely to kill a fellow hero, is able to drop him from high enough to take him out.
After that its HM and two legit class 100 guys. HF or not he gets put down next.
Then its a matter of who gets lucky between WM and Namor.
