The earliest stories introduce Yellow Claw himself, a supremely confident and thoroughly reprehensible genius who sells is talents to the Communist Chinese, or at least they suppose he has. He is opposed by noble FBI agent Jimmy Woo and torn between these two powerful men is Suwan, Yellow Claw's niece and Woo's true love. We also meet former Nazi and regular henchman Fritz Von Voltzmann. The formula developed by Sax Rohmer in his Fu Manchu novels is in place here with the Yellow Claw perpetrating some villainy and Suwan working both sides while Jimmy Woo seeks to find a way to end the menace.
Yellow Claw uses mutants to alter reality, and later tries to escape Woo aboard a ship with wild disguises, and uses a gigantic robot to fool some local natives into rampaging against the civilized world. It's all very rockem' sockem' with a frenetic pace.
The Claw makes use of a squadron of "microscopic" soldiers to infiltrate U.S. secrets, he works in league with an actual alien who is dubbed "U.F.O. the Lightning Man", and makes use of a noxious sleeping potion to subdue whole cities.
Yellow Claw enlists the aid of shadow people from another dimension, mutant birds who are creepily human, and a powerful psychic who puts people to sleep by means of television.
The stories are short little exotic masterpieces full of vigor and a bristling pace. Sometimes Jimmy Woo is effective, but often he is just lucky. The series ends with Suwan and Jimmy wondering where Yellow Claw will strike next.
It will be a while indeed. More next time.
