Galzforce

Galzforce, a non-canon body known only through mentions, acted as the armed wing of the warmongering state of Galzburg. Child soldiers were its signature weapon, thrown into suicidal operations and prodded to turn on their comrades as a route up the ranks. For record-keeping, each recruit went by a number and carried the label of whichever officer commanded him. The unit flew several emblems, chief among them the letters GF drawn in blue behind outspread white wings, while individual child squads bore a numbered red skull framed by vines.

The army lived to secure Galzburg's victories no matter the human toll, treating its youngest recruits as throwaway resources. A further insignia, a red X above a pale blue diamond, was handed out as a medal even though nobody explained what it stood for. The ruthless world it fostered scarred Douglas Bullet for life, whose refusal to trust anyone sprang straight from the treacheries he lived through. That solitude pushed him to rely on his strength alone and, after he could not overcome Gol D. Roger, to sign on with the Roger Pirates.

Only two members stand confirmed, Douglas Gray and Douglas Bullet. Roughly 45 years ago a squad under commander Gray came upon an abandoned infant and Gray took him in, rearing the boy as an ideal child soldier on nothing more than the bare essentials. At age eight Bullet was formally enlisted and began running deadly missions, placed ninth within a nine-child group nicknamed bullets; he outlasted them all, and that is how he got his name. Somewhere between nine and thirteen, starving on a mission, he came upon the Gasha Gasha no Mi that saved him, and the ninth-numbered form of his squad's skull crest eventually became his own Jolly Roger.

By the time he reached fourteen, triumph was near and Gray had climbed to commander, vowing to advance the boy should the war be won. Bullet forced the rival commander to give up, only to find himself ringed by his own side, sold out by Gray, who judged him too powerful to keep alive. In the fight to the death that followed, Bullet wiped out both Galzforce and Galzburg completely.
