The Manhunters infiltrated and liberated many planets disguised as living beings and created a "Cult of the Manhunters" that trained others to be their minions. On Mars, the people of that world started a group of Martian Manhunters based on the lessons of preserving justice taught unto them by the Manhunters and even erected a temple based on the appearance of their inspiration.
On Earth, most of the Manhunters' agents were unaware that their masters were robots, or that their real purposes were not noble. Some of these agents became superheroes also known as Manhunters. They wore red-and-blue costumes patterned after the Manhunters themselves. The most famous of these was a big game hunter called Paul Kirk. He was active in the 1940s, and starred in his own comic book. The character was brought back in a modern version in the 70s, in which he was supposedly killed years before but was in truth placed in suspended animation by a secret conspiracy. He was cloned, and when he finally reawoke, he dedicated himself to battle those who had used him, eventually dying in the process. However, some of his clones survived.
