This is probably the least known Thor out there! So a short history is provided. Dargo along with Thunder Strike, Beta Ray Bill, and Thor formed the Thor Corps. They had a short 4 part run.
I hope you like him, even though he's pretty obscure.
Let me know...
Dargo Ktor grew up on a future Earth dominated by the oppressive Corp; after the discovery of Thor's hammer Mjolnir embedded in some rock, some of the populace, the Cult of the Hammer, drew hope from the belief that one of them might prove worthy to lift it, and thus gain Thor's power. Though Dargo was skeptical, feeling the people should depend on themselves and not an old legend to gain their freedom, he and his girlfriend Salla still attended a secret ceremony on September 4th 2587AD where cultists tried to pick up Mjolnir. Having noticed the cult, and wishing to prevent them from restoring his extradimensionally exiled step-brother, Loki allied himself with the Corp and sent minions to attack the meeting; during the assault Dargo grabbed Mjolnir and, judged worthy, was transformed into an avatar of Thor. When even his rock troll Tyrus the Terrible proved unable to defeat Dargo, an angry Loki destroyed Corp Central out of pique, ending their rule. Sensing Mjolnir being pulled towards the true Thor, Dargo sent it to him through a dimensional portal.
