VXen

From publisher blurb: A catalyst for danger... VXen! A Power Level 12 Rogue, VXen is an evil genius who sees every situation as a recipe for danger! VXen is an iconic character in the Beacon City universe, but can be dropped into any campaign with very little alteration. VXen's file is designated "Blue" to represent her technological advantages. Her understanding of chemistry is superhuman, and she takes advantage of this mastery of the elements to manipulate any situation to her advantage. Her desire to gain power and complete lack of moral inhibitions makes her a very dangerous woman with unhindered ambitions. She makes a perfect foe for heroes who use their brains before their brawns, or for heroes dedicated to preventing collateral damage.
