After years of fruitlessly trying to bring peace to man's world, Diana of Themyscira was stripped of her rank and mission when her fellow amazons decided that she had not done enough to help the others with her message of peace.
With a new generation of darker heroes and the progressive isolation of her heroic former comrades, Diana felt lonely, though she still fought to bring harmony and peace to the world. When disaster struck America in the form of a rampaging Magog, Diana talked Clark into ending his retirement. Once Superman agreed to return to public action, Diana was the first one to join the reborn Justice League.
As their ranks grew, Diana and Clark began an affair. The two came into conflict with each other, though, as the measures Diana pushed for against the wildcard metahumans were often more radical than Clark was willing to approve. When the metahumans locked in the superprison that had been specifically designed for them began to riot, Wonder Woman led the charge of the Justice League to put a stop to the violence. The war between the league and the metahumans erupted.
Feeling threatened, the ONU dropped a special bomb that left very few combatants alive on either side. Luckily, Diana was one of the survivors. The traumatic experience caused Diana to reexamine her views and she returned to most of the beliefs she had held when she first set foot outside Themyscira. Her relationship with Clark was also stronger than ever, and resulted in a new breed of men and women of tomorrow.
