Isaac Lidman hated everyone. He worked a dead-end job as an accountant for a large multi-national corporation, stuck in a tiny office with no windows and a computer ten years out of date. His co-workers were mean to him, women avoided him, and he hadn't had a friend since elementary school.
It wasn't
his fault! He simply wished everyone could understand how they were always wrong about everything and that he, Isaac, alone understood the way things really were and really
ought to be. If only he could show them the errors of their ways!
Everything changed one night. Isaac was working late, because his stupid boss couldn't understand Isaac's true genius and had instead put him on some inane number-crunching project that took hours and hours to complete. Alone in the building, Isaac seethed with disdain and hatred as he plugged away at the numbers. Then, an unusual power surge raged through the building, through his computer, and into Isaac's nervous system.
All the electricity in the building immediately switched off. Although it was now pitch-black, Isaac could still "see" his surroundings, after a fashion. Moreover, he discovered that it was
his will that was keeping the lights out -- if he concentrated, he could control the flow of electricity in the area.
Becoming the masked entity
Blackout, Isaac now uses his powers to take out his frustration on a world that obviously doesn't understand him and hates him. Under the cover of darkness and power outages, he robs banks, jewelry stores, and other places, showing his disdain for the laws of normal men.
