Wonder Man (1991 series) #13

The brawl among the heroes at the Four Freedoms Plaza is out of control, with Wonder Man going into a berserk rage against mutants. "Calm" only comes when the gamma bomb explodes and the crisis unites the panicked heroes. Learning from Wolverine that Spider-Man and Hawkeye were blasted by the Iron Man doppelganger, Wonder Man enlists Thor and Hercules to search for them. Arriving at the site of the heroes’ defeat, they are confronted by a Wonder Man doppelganger. The two Wonder Men battle, with the real one strangely distracted and unable to summon the intensity to activate his full powers. Wondy is saved from defeat by the intervention of Thor, which causes the doppelganger to depart, with a promise of the heroes’ certain defeat. Wonder Man and company rush the fallen heroes to the hospital and return to the Plaza in time to join the expeditionary force.
