Avengelyne is a comic book character co-created by Rob Liefeld and Cathy Christian, and originally published in 1995 by Maximum Press. By the end of the 1990s, Avengelyne had a stint at Awesome Entertainment (one issue published only) and enjoyed a short stint at Avatar Press. It was recently announced that Avengelyne would be returning to comics in the Arcana Studio oneshot Avengelyne vs. Koni Waves due for a 2009 release.

Avengelyne is an angel who fights the forces of evil and often finds herself face-to-face with demons, monsters, and the like. The original character design for Avengelyne was based on the likeness of former Vampirella model Cathy Christian.

Avengelyne was the most feared warrior in Heaven's Warhost, having single-handedly broken into Pandemonium, the outer fortress of Hell, to confront the Devil himself. She is a fallen angel, banished from Heaven by God after being tricked into questioning His love for humans. Avengelyne was stripped of all her angelic abilities, other than her great strength and her blood, which, once extracted from her body, could be used as a weapon or a miracle once empowered by quoting verses from the Bible. Although He appeared truly angry, God was trying to prepare Avengelyne for a coming war for which she would need to be strengthened.

Keeping her faith in the Lord even on Earth, Avengelyne began to fight the demons she found while there. Eventually, one of her enemies, the demon lord B'Liale, sent a demon, Kyle Wagner, to seduce Avengelyne and father a powerful demon child. God sent Passover, the Angel of Death, to kill Avengelyne for her involvement, but the child, Magog, was born prior to the angel's arrival, and so together Passover and Avengelyne drove the demon-spawn away.

Seeing her devotion to Him was still strong, God allowed Avengelyne to live, and she still fights demons on Earth. Eventually, when Armageddon occurs, Avengelyne will lead Heaven's Warhost, with Passover as her second-in-command.
