The Fourth Musketeer is an actual French musketeer, risen from the dead to work against the German occupation of France. He says, "I cannot rest! Liberty, fraternity are almost dead in the world...I have a duty to perform!" The Musketeer decides that the "hope of the world lies in America" and travels to Washington, D.C. on a white horse, galloping across the waves. Once the Musketeer is in D.C. he supports liberty, fraternity, and egality by apprehending some bank robbers and capturing some pro-German types.
Apart from his cross-oceanic travel, he demonstrates no ghostly powers, but he is a good fighter and swordsman.
Note: Contrary to what Jerry Bails and Howard Keltner say, there is NO evidence within the actual stories themselves that the Fourth Musketeer and the Blue Blade were the same character. The only thing they have in common is that they have a general Musketeer theme, but other than that the characterisation, costumes, and origins are different. That said, there is some extra-textual support for the Bails-Keltner theory; see the Blue Blade entry for my comments on that.
