She first appeared in Countdown #46 (August 2007), and was created by Jimmy Palmiotti, Justin Gray and Jesus Saiz.

The process produced the Forerunners, a species possessing traits of the beings from other planets such as Green Martians and Saturnians.

In her first appearance, she battled Jason Todd and Donna Troy during their investigation of the death of Duela Dent.

Vowing to stay on Earth until she regained the trust of the Monitors, Forerunner was later contacted by Captain Atom (now called Monarch) who recruited her to aid him in his plans.

[2] Monarch discloses that Viza Aziv was chosen as the Monitors' warrior because they feared something in her: she was an unexpected outcome of the breeding program which created the Forerunners.

Forerunner boards the pirate ship, kills the captain, and evicts all non-necessary crew members.

Viza invokes the law of choice, a custom on her home world, empowering the victor to take any prize they desire.

The crew encounter an Earth space shuttle with a young boy in cryogenic stasis, whom they bring aboard.

During the trip, they are attacked, and, at the young planet's request, Forerunner places a drop of her blood onto its land, allowing it to create antibodies from her DNA.

Her rate of acceleration and maximum velocity has yet to be determined but she was fast enough that a normal human could not follow her movement.
