Jumpin' Jack Flash

Jumpin' Jack Flash is the Stand of Lang Rangler and appears in Stone Ocean. The humanoid Stand roughly matches Lang's own height and build. A dark band runs around its head at eye level, and a cartoon rocket ship is pressed into its chest like a stamp. Each wrist carries a rounded, cage-like part that spins at high speed to fling various projectiles. Colored pages render it grey and orange.

The Stand's crippling core power removes gravity from anyone Lang spits on, turning that victim into the center of a zero-gravity field that spreads to whatever they touch. The abrupt loss of weight leaves targets hopelessly disoriented. Worse, the effect chains outward and drains weight from the surrounding air, carving out a vacuum roughly 20 meters across that pulls blood from open wounds and eventually brings the bloodstream to a boil well before suffocation would. Inside that void, anything holding air can burst like an explosive, which Lang uses to hurl shrapnel at foes. The vacuum endangers Lang too, so he keeps clear while toggling the weightlessness of chosen people and objects and darting about on suction-cupped hands and feet.

For direct fire, the Stand mounts a centrifuge on each wrist that loads small parts like screws and bolts, spins them up to pack in centrifugal energy, then launches them as bullets. Since the ammunition is physical, Lang has to reload often, but he shoots skillfully and can even ricochet shots around defenses, pairing the barrage with the victim's own vacuum to widen their wounds and hasten blood loss.

Lang Rangler is the sole user. His setup is nearly impossible to counter once established, and defeating him takes the combined effort of Weather Report's versatile power and Jolyne's Stone Free.
