Peacemakers Planetary Problem-Solvers

Christopher Smith of Earth-Four grew up the sole child whose father was an army officer turned statesman and whose mother was a research scientist mother. His wealth, skill at flying fighter aircraft and scientific aptitude derived from each. Smith was employed as a pacifist diplomat working as Peace Envoy for the Geneva Arms Conference.

These two distinct worlds came colliding into one another with an international named Bork threatened the world's security. Donning the alias of Peacemaker, Smith utilized his various gadgets to full effect to topple the aspiring dictator. This incident led to his fully adopting a new role into his already complex life, as a world-traveling troubleshooter/costumed hero, a venture which would ultimately claim is role as diplomat.

Behind the scenes, Peacemaker incorporated several key pieces of technology into his state-of-the-art costume. Chief among these is his helmet which included a powerful laser always at his disposal, and a jet pack allowing him low-altitude flight when time was of the essence.

Additionally, with such items as his nitrocellulose pack, fire bomb vile and derringer, Smith always had to assess the situation to assure that the maximum effect to resolve a crisis was utilized  while attaining the minimum amount of devastation when such tools were used.

He found counterparts on Earths One and Two in the heroic Space Ranger and the despotic Duke Saturno, each with weaponry on par with Smith.

Rick Starr was the son of wealthy industrialist Thaddeus Starr who owned Allied Solar Enterprises in a distant future. After seeing trouble in the solar system surrounding Earth-One in his era, Starr become the costumed crusader. known as Space Ranger. Mephisto Saturno was royalty from the planet Saturn-Two, sent by that world's Emperor to conscript slaves from Earth-Two as Duke Saturno. 

Starr would have a long and distinguished career albeit not yet but in a potential future timeline. He even met Green Lantern and other prominent protectors of the 20th century during a couple cosmic crisises, including the Crisis on Infinite Earths. As for Saturno, Mephisto  repeatedly clashed with Wonder Woman from 1944 to 1947, trying to enslave humanity under his Emperors' wrathful rule. He and his master, now exiled on the moon Titan, would return in 1956 for one last bid for power... yet again Wonder Woman defeated them.
