Captain America has had his body advanced to the peak of human potential, but his mind didn't get the same treatment. That's why villainous psychiatrist Dr. Faustus has had success with him. The Austrian-born doctor is a master of manipulation who prefers to not engage his foes directly, but rather take control of their minds to make them essentially kill themselves. He's a master of the long con, which makes him one of Captain America's most dangerous foes.
