The first Scorpion was seen as a giant monster. During an experiment with a bismuth isotope, Paul Rodgers accidentally struck a normal scorpion with a stream of delta particles. It was mutated into a giant monstrous form and gained the consciousness to hate the human race. It told Paul Rodgers and Edward Bentley that it would mutate another bunch of scorpions and take over the world. Edward managed to hypnotize the Scorpion that it was feeling the pains from the radiation poisoning. When the Scorpion begged for Paul and Edward to end its life, they complied and killed the Scorpion by firing another stream of delta particles at it.

Sam Scorpio is an inventor who used his "sting" (a derringer fitted to a silencer on his forearm) to terrorize the Old West. Scorpion later encountered Kid Colt while running from a 50-man posse and begged for his help. Kid Colt refused until an earthquake occurred and they hid under a boulder. By the time Kid Colt and Scorpion emerged, the posse caught up to them and they were taken to prison. While in jail, Scorpion used his "sting" on a guard. Upon grabbing the guard's keys, Scorpion forced Kid Colt to accompany him. He took Kid Colt to a hideout in the hills and wanted Kid Colt to join him. When Kid Colt asked about the secret of his "sting," Scorpion turned on him. Kid Colt shot out the lamp for cover from Scorpion's sting and Scorpion fled where he told the posse where they can find Kid Colt. Afterwards, Scorpion set up a gang where he kept them in line with his "sting." Kid Colt went after Scorpion's gang upon figuring out what his gimmick was. Kid Colt defeated Scorpion's gang and defeated Scorpion in hand-to-hand combat before he could use his "sting." Kid Colt then turned Scorpion and his gang over to the authorities.
