Emperor

Hol Horse fights with Emperor, a Stand that manifests as an ornate, impractical-looking revolver touched with futuristic detailing. A metal frame wraps the long barrel, an unattached cylinder sits below it serving no obvious purpose, there is no sight, and a large sphere is set into the frame between hammer and barrel. Araki described the design as a revolver crossed with an automatic pistol.

Most versions color the weapon silver, though the OVA renders it gold. It stands for the Emperor of the tarot, a card tied to command and structure, and Hol Horse summons it directly into his open hand rather than drawing it from anywhere.

As a gun-shaped Stand, Emperor is a weapon first and foremost, and its deadliest trait is that its bullets count as part of the Stand itself. Because of that, Hol Horse can bend their flight path at will after firing. He guided rounds to loop around Silver Chariot's blade without hesitation, made them reverse into a full turn, and even threaded them through a cramped pipe he could not see into. Since the ammunition is really part of the Stand, the gun never needs reloading and behaves as though its supply is endless.

The limitation is range. Those same bullets remain bound to the Stand's reach, and while that reach is generous for a close-range type, the weapon's bite falls off sharply once the rounds near their outer boundary. A second, quieter perk is the way Emperor materializes right in Hol Horse's palm, which lets him spring sudden attacks and, in any quick-draw contest, get his shot off first.

Hol Horse is Emperor's only user. The Stand's power is potent but blunt, so he compensates for its simplicity by teaming with allies, coordinating his guided gunfire alongside partners to gain the advantage he cannot secure on his own.
