Background
Antonia Louise Monetti, or Toni as she preferred, was born and raised in London where she was something of an introvert and a loner. Along with her gothic interests, Toni would often do rebellious things like skip school and go out of the house at night without her parents permission. This caused her to have a bad relationship with her parents, whom disapproved of her lifestyle and were disappointed by her rebelliousness and bad habits. During one night, after sneaking out of the house to go to a rock concert, Toni was passing by a research facility along the way when an explosion occurred. Although she and nobody else was injured, the explosion exposed her to a new form of radiation the scientists were developing. This radiation altered her appearance by turning her eyes and part of her hair red and her skin became silvery-pale. It also gave her the superpowers of flight and energy manipulation/ construction, allowing her to form solid objects and fire energy blasts from her hands.

After realizing her potential and mastering her powers, Toni decided to run away from home to become an international super-heroine. With the heroic identity of Argent she traveled the world, operating in mostly UK Commonwealth nations. During this time, she gained a healthy reputation for her heroics and popular acclaim.
