Mariano Llanera's Skull Flag(1896). A somber-looking black flag, with the single white letter K and the skull and crossbones emblem. The black color of the flag was inspired by the hood worn during the secret initiation rites of the first degree Katipuneros. The flag was for the camp of General Mariano Llanera of Cabiao, Nueva Ecija, who earned for himself a reputation as a brave and reckless fighter. "Let us fight to the finish," was one of his favorite remarks. This flag looked like the pirates' banner in the Caribbean. It is said that Andres Bonifacio made fun of this flag, calling it "Llanera's skull."
