Lady Luger battled the Blue Bulleteer during World War II and she has battled Nightveil in the present. During the Yesterday Syndrome, the Nazi fiend was even successful in sending murderous volts of electricity through Laura's body with some help from the Shroud.

Lady Luger

Gorgana

For Gorgana, possession of Nightveil's Mystic Cloak of Darkness means unlimited power, even the power to make her ghoulish form beautiful, and that makes the monstrous witch a persistent enemy.

Umbra
Umbra is a Voodoo Priestess who was hired by the crooked trustee of the Wright estate to eliminate Nightveil when the Sorceress returned from her studies in Limbo and reestablished her claim to the Wright property holdings. Umbra's black magic struck the mystic maiden down but, with the help of the Shade, Nightveil was able to defeat the voodoo queen and save her own life, earning Umbra's everlasting enmity.

In 1956, a young witch named Lenore Gault and her mentor, a wizard named Rocksorr, tried to kill the Blue Bulleteer. What Laura didn't know at the time was that she would one day become Nightveil and the little girl would become the evil sorceress, Alizarin Crimson. The malevolent witch's efforts to destroy Laura and become the dominant sorceress on Earth have reached through time and space and Alizarin Crimson is unquestionably Nightveil's arch-rival.
