Comments:
Johnny's Thunderbolt manifests itself invisibly in this story making it appear as if Johnny's magic actually works on people around him, rather than his Thunderbolt.

This story is continued in part from the fourth story of Flash Comics #4.

This story originally was not titled; the title shown here was given on the contents page of JSA All Star Archives Vol. 1 in which this story is reprinted.

Synopsis:
Johnny joins the FBI and becomes a G-Man. His first case is to investigate the disappearance of a bank vault. The entire vault is gone including a man inside, Johnny's father Simon Thunder.

Johnny becomes suspicious of a piano company across the street from the bank. When he enters the building, crooks capture him. The crooks have tunneled under the bank from the piano company building and caused the bank vault to fall underground. They then sealed up the floor, so the vault can't be seen from above inside the bank.

Using his Thunderbolt powers which he doesn't know how to control, Johnny is able to rescue his father and apprehend the crooks.
