As Diana, Victor and Arthur all try to simultaneously flank Superman (albeit unsuccessfully), Barry attempts to help using his speed, but Superman is able to see him and keeps up with the speedster. Despite Barry's best efforts, Superman is able to land a glancing blow, knocking him out before Batman arrives and gets Superman to stop. Wonder Woman tries to fight Superman again, yet she's knocked down. He then swats Batman and asks him the same question that Bruce asked him "Tell me, do you bleed?". Before Superman could kill Bruce, Lois and Alfred to stop him.
The Crisis on Infinite Earths crossover of 1986 was designed and written with the purpose of streamlining most of DC's characters into one more-focused continuity and reinventing them for a new era, thus Wonder Woman and Steve Trevor were declared to come from the Earth-Two dimension, and along with all of their exploits, were erased from history, so that a new Wonder Woman character, story and timeline could take priority.
Wonder Woman and the other heroes were finally released from the Firestorm Matrix when Batman used the Lasso of Truth on Firestorm. Superman was still infected with the Kryptonite shard inside his nervous system, but Lex Luthor was able to extract it, saving Superman's life. Luthor also assembled a group of villains that defeated the Crime Syndicate. Later, at the Batcave, Wonder Woman and the Justice League talked about the enemy that destroyed the Crime Syndicate's world and came to the conclusion that Darkseid would return.
