Marvel: Venom Blasts

Jessica Drew (Spider-Woman)
Her body possesses an inordinate amount of bio-electricity that she has learned to channel and discharge through her hands, in controlled bursts of what she calls "venom blasts". These energy projections vary in power; they mostly affect the nervous systems in humans. Spider-Woman can regulate them from simply a stun to potent enough to kill an average-sized man in the same way that a lightning bolt could kill him.
