After returning to Earth as Nightveil, Laura felt that her awesome power was slowly draining away her sense of humanity. So, she placed a spell on herself which temporarily stopped her from being able to use all her powers and she attempted to resume her role as the Blue Bulleteer. However, unused to not being able to rely on her sorcery, her return to life as the Blue Bulleteer was short-lived and she reluctantly donned the guise of Nightveil once again. Still, her desire to remain human persisted and her enemies, like Alizarin Crimson, used her innermost fears against her.

Nevertheless, it is the villains who have the most to fear from the Sorceress Supreme...and fear her they do. Her awesome might has earned her many enemies and, out of respect for her power, plans for world domination must start with a means to eliminate her as a threat. Her foes usually attack through her fears or desires and are only successful when they can catch the unsuspecting Mystic Maiden with her guard down.

However, even when she has seemingly been defeated, Nightveil's innate courage and dogged resolve have always served her well, allowing her not only to survive situations such as being lost in the starfield of her mystic Cloak of Darkness but to eventually prevail.
