Emily Sung, also known as Element Woman, is among the heroes summoned by Cyborg to address the growing threat of the conflict in Europe. She possesses the same abilities as a Metamorpho, able to change into various elements. She is eager to join Cyborg's fight against Aquaman and Wonder Woman, who are ravaging Europe. Some of the other assembled heroes are not as eager to join the fight, among them the Enchantress who criticizes her eagerness, although Shade tells Enchantress to let her be. According to him, his meta-vest can tell she's "a bit mad. When Thomas Wayne declines to join the cause, the group is disbanded before their mission can begin.
She is later seen spying on Cyborg. However, rather than leaking information, she does this because she is somewhat infatuated with Cyrborg, who asked her to be on a team- something no one else had ever done. When Cyborg, Batman and the Flash launch an attack on the Project Superman building to liberate the captive Superman, Emily saves the group after Superman runs away, unable to cope with battle. She successfully knocks out the guards at the Project by turning into a knockout gas.
Emily continues to accompany the new gathering of heroes as they travel to visit the members of S.H.A.Z.A.M. Despite her social awkwardness, she offers to help the group and joins the mission to the elevated coast of New Themyscira. After the death of Billy Batson, Emily uses her powers to protect the remaining children alongside Cyborg.
Emily is socially awkward, and talks unnaturally. Overall her demeanor can be called childish; for example, offering juice boxes to heroes in the middle of battle.
Following Flashpoint, Emily is a confirmed member of the Justice League of America.
Element Girl is seen with The Justice League in the FCBD The New 52. In what capacity as a new member or ally is yet to be determined.
Andy Kubert's original design of her looked similar to the design of the Elemental Girl's black costume.
Original notes by Geoff Johns about the character states that "Breath smells like chalk, transmutes body into any element or compound, colorful exterior and smile hides sadness, closer talker, socially awkward."
Element Woman is called into help by Cyborg after Ocean Master has captured Batman, Superman and Wonder Woman. Cyborg calls in Black Lightning, Vixen, Shazam, Green Arrow, Zatanna, Hawkman, Black Canary, Firestorm and rookie Goldrush. She is invited by the Justice League to become a member. She makes reference to knowing Rex, known as Metamorpho.
