Leslie Willis

Leslie Willis is a former employee of CatCo Worldwide Media. After a helicopter accident, Leslie was turned into the villain Livewire.

Becoming Livewire
She was once a radio shock jock presenter, working in the basement of CatCo Worldwide Media, until her shocking rants about Supergirl started to annoy everyone, including her boss Cat Grant. Furious, Cat ordered Leslie to no longer speak her opinions about Supergirl, to which she refused. Since she couldn't fire her, because Leslie had a two year contract, Cat had her transferred to the traffic chopper, much to Leslie's fury. On her first evening on traffic chopper, there was a storm. Despite the pilot's concerns about the weather, Leslie refused to return to HQ. When lighting struck the chopper and started to spin out of control, Supergirl came to the rescue, but when she took Leslie's hands, a bolt of lighting hit both of them.

Leslie was in a coma after being hospitalised, and after Kara and Cat paid her a visit she regained consciousness as electronics around her began to flicker and short circuit. After being discharged from the hospital, Leslie was walking around town as she began to notice her hands were charging with lighting. When a man accosted her in an alley, she unconsciously blasted him with electricity and got a rush from it.

Going After Cat Grant
After cutting off all power at CatCo, Leslie, now calling herself "Livewire", paid Cat a visit and attempted to use her new abilities to kill her. However, Supergirl showed up in time to intervene. She offered to help Livewire but refused. During the fight, Livewire fed off Supergirl's heat vision, and then caused the elevator that Cat was in to fall out of control before fleeing. During the DEO's investigation, Hank Henshaw revealed to Kara when that lighting went through her body it passed onto Leslie, turning her into pure energy.

In a attempt to capture Livewire, Cat and Kara (as Supergirl) broadcast an invitation to meet her on the street where Cat and Leslie first met. Livewire showed up and despite Cat's best effort to reason with her, Livewire opting to electrifying her boss, only to be stopped by Supergirl. The two women engaged in a fight, and Livewire quickly overpowered Supergirl, making it impossible to use the DEO's trap. Supergirl then found an underground water pipe and doused her with water, knocking Livewire out. Afterwards, she was taken into custody by the DEO and contained.

Powers and Abilities
Leslie is pure energy, able to transform into electricity and travel through anything that will conduct an electric current. She can also conjure lightning blasts of various intensities and lengths. In her electrical state, Leslie can possess and control any device that conducts electricity, even cause a black out through an entire city. Leslie's main weakness is water, and even small amount can harm her. To suffer a major power loss Leslie has to be completely drenched in water.

How powerful Leslie is depends on the amount of energy she possesses, and like a battery her powers are not indefinite. To re-power herself she must absorb a vast amount of electricity from an available power source. Even the energy from Kryptonian heat vision is a suitable power source. If Leslie is completely drained of her power, she reverts to her solid form and cannot use most of her abilities or transform into living electricity.
