Sergeant Spook

Golden Age Origin
The man who would become Sergeant Spook was a police scientist killed in a lab explosion. It was caused by when he accidentally place his pipe too close to a highly flammable chemical filled rack. The sergeant discovered after the explosion that now he was a ghost who was only visible and able to be heard by Jerry, a teenager. Sergeant Spook decided to become a crime fighter assisted by Jerry and Dr. Sherlock. He later discovered ghost town home to famous ghost such as Captain Kidd, Robin Hood, Johnny Appleseed who became his allies and Napoleon Bonaparte and Jesse James who became his enemies. Sergeant Spook's powers included invisibility, intangibility, and being able to make contact with the physical world even though he is a spirit.
