War Angel is a fictional character created by Brian Pulido for his new line of post-Chaos comics at Avatar Press. She exists in the same universe as the rest Pulido's new line including Lady Death and Unholy.
War Angel is supposedly thousands of years old, having appeared in the distant future in her own series, and having fought alongside Lady Death in her time. Little is known about her past, but she has no conscience, a quick temper and a taste for mayhem. More will be revealed about her as Pulido's new universe develops.
War Angel is, literally, a "war angel", created by God to do one thing, make war.
In the 2005 three issue mini series War Angel, set in the future in the year 2232 AD, Serenity (her real name), travels to what is left of Nevada to hide out and get some cash before heading off to Xexico. She gets in the middle of a drug war between vampires, warlocks and werewolves. She kills all parties involved, but doesn't get any money to show for her efforts.
Even though she claims to have no conscience, she seems to have a soft spot for women in peril. She develops feelings for Scarlet, a siren captured by the head of the warlocks named Marax and made into his slave. After Scarlet tells her about being taken from her home and her wives, Serenity kills the warlocks guarding Scarlet so she can escape back to her home known as "The Hive". Scarlet gives Serenity an invitation to come visit her at the Hive if she makes it out of town alive. Serenity takes Scarlet up on her invite and is given shelter and companionship from Scarlet... and her wives.
Serenity also tries to help a prostitute she hires for the night whom she calls "Blondie". After surviving an attack by the warlocks, she gives Blondie money and tells her to start her life over. Unfortunately Blondie is beaten to death inside the brothel by Samuel, the head of the vampire clan.
In 2006, Lady Death vs. War Angel was published, giving a little insight to Serenity's origin. War Angel blames Lady Death for what has happened to her left hand. They fight to a virtual stand still. War Angel slightly gets the upper hand and is about to finish off Lady Death until Pandora intervenes and hits Serenity on the back of her head and teleports her away.
In 2007, War Angel 0 was published, and gave yet more insight into the origin of War Angel. Serenity is upset over the fact God has not spoken to her in thousands of years (which contributes greatly to her personality) despite having done everything possible to get his attention. Serapiel, the angel of judgement shows up after seeing Serenity tie up a group of angels upside down in order to drink their tears. He brings with him a demon from hell to kill War Angel fearing she is the biggest threat of all. She disposes of them both and starts the great war that leaves the world in ashes.
