Glory is a fictional character originally from Image Comics, and later on from the Awesome Comics comic book series created by Rob Liefeld. The character's full name is Gloriana Demeter, a half-Amazonian, half-Demon warrior.
Glory was the result of an alliance between the Lady Demeter of the Amazonians and the demon Lord Silverfall of the Underworld. Raised in her mother's world and trained by the Amazonians, she emerged as their finest warrior. However, she also struggled to control the savagery which was her paternal gift/curse. Not at home in either Amazonia or the Underworld, Glorianna went to the world of man.
During World War II, Glorianna fought for the Allied forces against the Nazis, alongside Supreme, another Liefeld creation. For a time she worked with Die-Hart and SuperPatriot as the team called 'Allies'.  She was part of the second and third Brigade teams with other superheroes.
Writer Alan Moore joined Image after having left DC Comics and spending a period of time working for independent companies. As he did on other Liefeld/Image works like Supreme and Youngblood, Moore relaunched Glory in March 1999 under the Awesome Comics line, blending mythology, adventure, and romance to the superheroine much as he would shortly do in his subsequent series for ABC Comics, Promethea.
In the retooling, Glory takes on a human identity by a waitress named Gloria West, in order to experience humanity. Only one issue was published (#0), but it was eventually republished with two additional issues for Avatar Press in 2001. This version also had a long history, once supervising a team called 'Danger Damsels' decades ago. 
In 2011 it was announced that Joe Keatinge would be the writer for a relaunched Glory ongoing series with artist Ross Campbell. The series was not renumbered and begins at issue #23. Glory's history is retooled, establishing the Amazons and Demons as aliens. Glory was also redesigned to be more muscular and covered in battle scars.
