Dave Cox was originally portrayed as a wounded Vietnam War veteran. He lost an arm in the conflict and had became a conscientious objector that renounced violence. He was captured and tortured by the Serpent Squad, but still refused to fight the villains. Captain America noted his admiration for Dave's convictions.
Dave grew romantically attached to Sharon Carter. When she and Steve Rogers had a disagreement, Dave's shoulder was available for Sharon to cry on. Dave's feelings for Sharon; however, were unrequited.
Later, Steve Rogers sought out Dave and they both discussed what they thought was the untimely death of Sharon Carter. Dave had moved on his life and now had a wife and child. In a cruel demoralizing plot, the Red Skull kidnapped Dave, brainwashed him and gave him the cloak and powers of the Devil-Slayer. Despite their friendship, Captain America was forced to defeat Dave. The Skull relished the fact that Captain America had to seriously injure his friend, Dave, in order to defeat him.
Dave apparently later recovered from his injuries and brainwashing.
