Electrokinesis

Benjamin Franklin (Heroes)
According to Joseph Priestley, Benjamin Franklin told him that during his initial kite experiment, he absorbed enough electricity to kill a normal man from the lightning bolt that struck the kite and traveled down the wet string. He also claimed that afterwards, he released the stored energy by touching his cat.

Cooper (Heroes)
Cooper has the ability to generate and manipulate electricity. With this power, he has been able to kill many city people.

Elle Bishop (Heroes)
Elle had the ability to generate electricity. She seemed to have excellent control over her ability, allowing her to generate electric arcs of varying intensity and target them precisely.

She had demonstrated skill ranging from welding a lock shut to sending a powerful burst that struck a running Peter Petrelli in the back and knocked him over, lighting his shirt on fire. One of her favorite things to do was to send small, stinging bursts of electricity into another person.

When her life was threatened by Sylar, Elle let out an incredibly powerful blast of electricity that knocked out Sylar and the grid supporting Level 5. After this event, Elle's power went out of her control, tending to overload whenever she became stressed or angry, causing her to shock herself and things she came into contact with. On the way to Pinehearst with Claire, Elle caused the plane's navigational systems to malfunction, nearly causing the plane to crash. Upon meeting Sylar once more, despite her lack of control, Elle was able to unleash her pent-up rage and power upon Sylar, generating incredibly powerful lightning bolts. By forgiving herself, Elle regained control of her powers.

According to her assignment tracker profile, Elle's control index was 46%. Her data analysis shows her biological level at 40, cerebral at 15, elemental at 80, and temporal/spatial at 30.

Jeanne-Marie Beaubier (Marvel)
Beaubier has the ability to project lightning blasts with devastating results.

Unnamed teenage patient (Heroes)
This person has the ability to create electrical arcs. Mohinder witnessed him emit electricity from his fingertips and face. He apparently has no control over his power; he simply absorbs energy from nearby electrical systems until he reaches a critical point at which the energy escapes as an electromagnetic pulse combined with electrical arcs to nearby objects. These energy releases are not healthy for him; he was hospitalized and near death from their effects when Mohinder found him. He can avoid absorbing energy and suffering from uncontrolled energy releases by staying away from electrical equipment and power lines.

Unnamed Agent (Heroes)
The agent has the ability to create and direct electrical arcs and generate enough electrical blasts to stun or kill people. He also has the ability to allow himself to levitate, however how this works is unconfirmed.
