I've done this so that you, my adoring and helpless public can gaze upon moi, your lovely queen of all media. Actually, I pretty much am the media now, seeing as I've taken complete control. So don't touch that dial, Metropolis, because if you ever want your phone back, your lights, your talk shows, your home shopping channels and your stupid little lives, then you're gonna have to deal with me!
~ Livewire, holding Metropolis hostage.
Livewire (real name: Leslie Willis) is an electrokinetic supervillain and she is an enemy of Superman.
Leslie Willis was a popular WLXL shock jock who ridiculing and insulting people around Metropolis, mostly Superman. People all over Metropolis listened to Leslie, even Superman, who is completed annoyed by her venomous words. Lex Luthor, in particular, enjoyed her radio show.
Leslie was interviewed by Lois Lane and Clark Kent about her views on Superman. Leslie explains 3 main reasons why she hates Superman: the first one is that Superman is never around when anyone needs him, the second one is that everyone is so easy for him to interfere, and the third one is that he cares about himself. These claims were disproven, when Kent secretly left the interview after hearing of a large crane falling from the top of a building, endangering a worker as well as a woman and her child; and despite his difficulty to stop the crane from falling, he manages to save the worker, the woman, and her child from being crushed. Following the end of the interview, Leslie announces the upcoming party in Centennial Park to celebrate the third anniversary of her show.
During the party, there was a thunderstorm, and Leslie's producer tried to convince her to close the party because of the arriving police's concerns for the risks of the concert during a thunderstorm and the crowd's safety. Leslie refuses to take note of her producer's warning and went so far as to incite the crowd against the police. The chaos continued until Superman arrived. But Superman couldn't convince her to stop the party. In fact, she took Superman's appearance as an opportunity to ridicule him in public. Then, suddenly, while verbally attacking Superman, a bolt of lightning simultaneously struck the stage, forcing everyone to evade from the bolts. Leslie, on the other hand, sees this amusing, forcing Superman to push her out of the way before being shocked by the electrical currents. Upon witnessing this, Leslie tries to escape, but she steps on a wire and gets shocked as well before falling unconscious.
Upon regaining his strength, Superman takes Leslie to Metropolis Hospital, where she recovered and quickly learned that not only had her hair and skin changed color. She blamed Superman for her transformation, refusing to take the fact that she should've shut down the concert that caused it in the first place. She later finds out that she has the power to generate and manipulate electricity. Delighted, Leslie escapes from the hospital via electrical current, and the former radio personality renamed herself "Livewire" and started her life as a criminal.
Sometime later, when she was being transported through Gotham City, Livewire escaped again and escaped into the Gotham underworld. There, she met Harley Quinn and Poison Ivy.
