The New 52 version of Earth 2 was introduced in Earth 2 #1 (2012). In that issue, the Earth 2 Wonder Woman is introduced via flashback. She, along with Superman and Batman, are depicted dying in battle with forces from Apokolips five years in the past. This Wonder Woman worshiped the deities of Roman mythology as opposed to the Greek; the Roman gods perish as a result of the conflict. An earlier version of the Earth-2 Wonder Woman, prior to the Apokoliptian invasion, is seen in the comic book Batman/Superman, where she is seen riding a pegasus.
She is able to astrally project herself into various lands of myth. Her physical body reacts to whatever happens to her on the mythical astral plane, leaving her body cut, bruised, or sometimes strengthened once her mind and body are reunited. She can apparently leave the planet through meditation and did this once to rescue Artemis while she was in Hell.
Though Diana was able to admit honestly that she did love Hades, she escaped her bonds anyway, explaining that she could still love him and refuse his proposal. Angrily, Hades sent all of the forces of Hell to kill her, but she and her friends were rescued by Strife. Confronted by her fiancé again, Diana explained that she had not lied. Wonder Woman has the capacity to love everyone - a concept that could never be understood by one incapable of love, such as he. The realization that he was loved unconditionally disgusted Hades so much that he sent them all away. Before leaving, Hephaestus gifted Hades with a mirror, and shot him with Eros' pistols, allowing, at least, for Hades to love himself.
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.
