Terry Sloane

Origin

While driving his car and contemplating suicide, he saw a young woman about to jump from a bridge. Sloane rescued her and discovered that her name was Wanda Wilson and she had been driven to despair by the fact that her younger brother, Billy, had gotten involved in criminal activity. Billy was working for a gangster he idolized named Big Shot.

Sloane disguised himself with a mask and costume and, before the eyes of Billy and the other kids in the gang, fought off Big Shot's men and drove them out of town. The boys had a new hero and Billy named the costumed Sloane, "Mister Terrific."

Having found the challenge he sought, Sloane continued to fight crime as Mister Terrific, defender of Fair Play. He became a member of the All Star Squadron and the Justice Society. Sloane eventually retired and became an English teacher at Gateway University. However, when his old enemy, Roger Romaine - the Spirit King - resurfaced, Sloane resumed his Mister Terrific identity to track him down. However, the Spirit King strangled Sloane, killing him. The JSA have vowed to avenge his death.
