There's another character in my book that has another interesting take on electric abilities. Her power is that she can produce both light and heat from within her body. This is a useful power for getting out of some sticky situations. When captured, she can heat herself up and melt through things like zip-ties or hand-cuffs. She can also light up dark areas when the team has to make a quick escape through some dark sewers. Although these powers don't sound very electric in origin, I assure you they are. McKenna's power comes from her ability to control the current and resistance in her body. By increasing both, she acts like the filament in a light-bulb or a space heater. Thinking like this it would make sense for her to also be able to manipulate her electric potential, expanding the range of her powers and allowing her to perform even more incredible feats.
