[5] In the Silver Age stories, Lucy was presented as an airline stewardess who was an on-again, off-again romantic interest of Jimmy Olsen.

[9] Lucy was an air traffic controller, but became affected by a mysterious blindness (implied to have poisoned by Lex Luthor) that was cured as a side-effect of the destruction of a Bizarro clone.

Bitter and angrier than in her former appearances, she still blames Lois for General Sam Lane's apparent death during the war against Imperiex.

[14] She later attacked Reactron, which tipped off readers that Superwoman was not Kryptonian (in that the villain's Gold Kryptonite power source had no effect on her).

[15] Supergirl unmasks Superwoman,[16] and accidentally kills her by rupturing the containment field of her suit, causing Lucy's body to contort and explode.

[18] When Lucy is recovered by General Lane's forces, they learn that the suit's mystic energies have somehow transformed her into an actual Kryptonian.

After interference by an object that crashes into a Metropolis park, before they leave Lucy's holding cell, it is shown seemingly to have lightly cracked.

[22] Although the crack in the cell seemed to hint at Lucy escaping at some point, nothing came of it, and once The New 52 was launched, all storylines in progress in DC were dropped in favor of the new continuity.

[23] Although Superwoman originally had no inherent powers, her powersuit altered her DNA via a containment field to resemble that of a Kryptonian and as such would potentially make her capable of all the same feats they possess under the yellow sun.

The abilities she has used thus far are; vast (possibly limitless) superhuman strength, speed and durability, invulnerability, flight (normal and interstellar), freeze breath and heat vision.

She confirms that she possesses super hearing when she murders a scientist working for Lane, though she does so with some form of energy blast from her hand, a power that is not among the abilities of a Kryptonian.
