Evil scientist Dr.Doom has created a super-villan that can absorb electrical power from any power source just by touching it. 
The right arm has the ability to exert those initial electrons to create a shock wave that can be used against an enemy. 
The left arm has the ability to absorb electrons from energy sources. 
Elecrto girl  was programmed by Dr.Doom to destroy the world. Her first mission is to kidnap Elon Musk and force him to create her an endless source of power to charge her energy from. 
Electro girl needs to use 608N of force to capture Elon Musk because he has a mass of 62kg. And in order to produce a force of that magnitude she needs to move around 1.6 x 10^16 electrons. 
Elon Musk has just gotten off of work, now is Electro Girls chance to kidnap him. Oh but wait, her nemisis, Iron girl, is here to protect Elon. They are nemisis' because Iron girl possess the only object that can repel Electro girls shock waves, a shock shield.
