Spy Smasher (Alan Armstrong)

Similar to Batman and the Blue Beetle (Ted Kord), Spy Smasher (real name Alan Armstrong) is a master detective, equipped with a number of gadgets and a specialized vehicle, the "Gyrosub", which was a combination airplane, automobile, and submarine. Created by Bill Parker and C. C. Beck, Spy Smasher was introduced in Whiz Comics #2 (February 1940). Alongside Captain Marvel, Spy Smasher became one of the magazine's most popular characters. In Whiz Comics #16-18, he was briefly an opponent of Captain Marvel, as a Nazi Scientist and old enemy of his, the Mask, used a device to brainwash him, but finally Captain Marvel was able to restore his mind.

His name was changed to Crime Smasher after World War II ended, and the first issue of Crime Smasher was published in 1948. In 1953, Fawcett ceased publication of all superhero comics, after settling a lawsuit against DC Comics over Captain Marvel being an infringement on the copyright of Superman, agreeing to cease publishing Captain Marvel.
