O.R.D.E.R is a law-enforcement, and counter-terrorism agency that exists within the Nova Universe. Here is the leader of their Alpha Response Team Harvey Hartman or as he is known as the Sentinel.
Hartman was a proud patriot and is a third generation soldier. He was an expert tactician and field commander and master of hand to hand combat. Hartman was the first Australian to be legally injected with a SuperSoldier serum. The serum has granted him his strength, endurance, agility, speed, reflexes, durability, and healing at the zenith of natural human potential.
He was fighting in the Middle East helping defeat a group of rebels from attacking a village when suddenly he heard the call. The call for help, a rescue mission. He gains the help of a fast talking, bow and arrow-wielding thief and a gentle doctor with unspeakable powers. Can he lead this team of misfits? Can he find the source of the mysterious voice?
