Not only is Herc stronger, he's also an infinitely better fighter than Samson. Herc wins without mjuch sweat.
__________________ I'd like to share a revelation that I've had during my time here. It came to me when I tried to classify your species that I realized you aren't actually mammals. Every mammal on this planet instinctively develops a natural equilibrium with its surrounding environment, but you humans do not. You move to an area and you multiply, and multiply until every natural resource is consumed. And the only way you can survive is to spread to another area. There is another organism on this planet that follows the same pattern. Do you know what it is? A virus. Human beings are a disease, a cancer of this planet. You are a plague, and we...are the cure.
Doc hit Hulk one time in this comic where Hulk was seeing images of his foes like Abomination Juggernaut Modok Rhino and then he see Doc Samson and by that time he doesn't even give any mind to him well Doc see this a gives him a punch as hard as he can and it knocked Hulk out but in the process breaks his hand
Hulk had his guard down, however. He belived Samson wasent real just as well. Under the same writer, Samson concead that Hercules was stronger than he was.
