Danielle Carter, AKA "Avenger", is a super hero operating in New York.
As a young girl, Danielle's favorite was a costumed heroine called The Avenger. Danielle took the arrival of Britanny Diggers who was currently stuck in her hybrid form, (were-cheetahs' without training can only change forms once every 24 hours when not under the effects of a full moon - Britanny had changed without knowing how to change back.), to her high school as a good sign and was facinated by the were-cheetah. They became fast and lifelong friends. They had an adventure or two as Pink Avenger and The Cheetah during those times in high school which affirmed for Danielle that that was what she wanted to do. Out of High school she went on to college became a lawyer in New York. There she took up the role of the superhero Avenger and has been "heroing" it up ever since.
In New York - Avenger quickly made a name for herself in both the superhero and the super villian societies. Interestingly enough, both sides find her to be a pain. This is because she refuses to go "undercover" as a hero with Agency Zero, because she believes she serves a dual purpose in being a visable deterent to crime, and of course because she interferes with the schemes of active super villiany. She has no super powers but is a very intelligent Olympic class athelete with martial arts, Weapon use, and a tech base that allows her crime fight effectivly. She has the trained dexterity to perform acrobatic manuevers and do things like Swing from building to building as a form of transportation and catch a thrown knife out of the air without injuring herself.
