Captain America's Shield

As a cloak, it protects—a barrier of sorts, A safeguard, like umbrellas to rain. A breastplate not worn; a mask unadorned A rampart-type bulwark, restrained. Initially triangular, now morphed to encircle, An offensive Vibranium guard—THAT DEFENDS! Red, white, & blue armor, plated to sparkle. Ensuring swift justice, as a means to an end. Captain America’s shield is a symbol, For times when character wanes. An instrument of warfare—that's nimble, Serving good wrapped in villainous chains. The shield defends freedom, And the American way. An armored symbolic medium, Dispersing the evil of human decay. Submission to Robert James Liguori poetry contest: Captain America's Shield
