Like his counterpart on Earth-Two years earlier, Greg Sanders used his natural talent as a marksman to uphold justice as a modern day vigilante, following in the footsteps of the heroes of the old West. He eventually retired and took a job as a security guard at a chemical plant, but uncovered a plot by aliens called the Doomsters to use the plant to pollute Earth for their own ends. Sanders sought the help of the Justice League of America in defeating the Doomsters and then, inspired by the adventure, continued to fight for justice as the Vigilante once more.
