There's a new superhero (or is it heroine?) in town. Rumors of an electrically powered individual appearing, saving the day, and vanishing again have been spreading. The news has enough witnesses to take it seriously and at least investigate, and a few police have SEEN "The Spark" with their own eyes.
However, stories vary. While the Spark is always crackling with at least some electricity, and wears a skin tight costume of black with gold lightning like designs all over it and a domino mask, one officer says The Spark is a black female, about 5'6" in height, where another announces she's a blonde woman closer to 5'4". A person Spark rescued assures everyone that , no, the Spark is a 5'10" man with brown hair. Yet another witness, a young kid, assures everyone that The Spark is his dad, but the boy's father is a 52 year old balding man who admits he has no idea what his son is talking about.
One day, as is typical, the hero is out with a DNPC when a rampaging supervillain (Ogre, Grond, pick one) comes onto the scene. As your hero gets ready to throw down, there is a bolt of electrical energy that seems to strike the DNPC and then BOOM, suddenly said DNPC is wearing aforementioned costume, with glowing eyes behind the mask.
"I am the Spark" Your DNPC announces, and proceeds to act most heroically. Not only does he/she have powers, but his/her body seems temporarily more athletic and any disabilities have been removed. The Spark (Now your DNPC) seems a 'standard' Energy Blaster and fights competently and valiantly. Spark seems willing to risk his/her life to save other innocents and stop the bad guy.
When the battle is done, a similar charge of energy to the one that claimed your DNPC leaves him/her and they 'wake up' with no memory of what just happened.
It becomes clear that "The Spark" uses the average citizens of your city as hosts to fight crime. Were it risking its own life, that would be fine, but the being in question must have a host to utilize its abilities. As more reports of "The Spark" hit the news, it becomes apparent bodies of the elderly and even children are not above the use.
