@dredeuced: But these scan not really from Pre-crisis,this scan just post-crisis,i doubt the AM power level is same thing
The comic happened in a post Crisis comic, but it was a time travel comic so they went back to when Crisis happened. What don't you get about this? AM was specifically more powerful than before because he had won instead of lost because of Barry Allen's premature death. That alone means he was more powerful because he lost before.
Wally had to go back in time and prevent Barry from ever dying so that history could right itself, but that Anti Monitor is legit COIE Anti Monitor.
