Count Luchino Nefaria
Born a wealthy Italian nobleman, Count Luchino Nefaria used to lead one of the Maggia Crime Cartel families until his defeat by the Avengers cost him the position. His fortunes dwindling, Nefaria subjected himself to an experimental process to give him super-powers. Soon after, he discovered he needed to drain ionic energy from others to prevent his body aging at an enhanced rate, and captured Wonder-Man and Atlas, bringing him into conflict with both the Avengers and the Thunderbolts.
Fully charged, Nefaria has nearly immeasurable superhuman strength and durability, superhuman speed, the power of flight, and the ability to fire powerful laser beams from his eyes. More recently, he has also proven capable of forming and manipulating crude ionic energy constructs. Nefaria must periodically absorb ionic energy from outside sources or his powers fade and he ages rapidly. Nefaria apparently shares the regenerative powers typical of ionic beings, enabling him to heal himself from a seemingly deceased state or even reintegrate his bodily matter after exploding. Nefaria is a charismatic natural leader and a capable criminal strategist, well-versed in the use of various exotic technologies.
