D-I-S-C-O

Tall, slim, and fairly handsome, he wears messy, curling dark hair of medium length, fixed with a large rectangular clip on the left side of his head. Blue eyes sit above a trimmed beard and mustache. His outfit recalls the long coat of an eighteenth-century policeman, held shut by a belt whose buckle is shaped like a handcuff, and his Stand rides his left forearm like an arm brace.

Expression rarely crosses his face, and he says almost nothing beyond naming his Stand. Beneath that flat exterior lies a practical mind, however; when a fight slips beyond his control he abandons the Stand and reaches for a revolver, showing he keeps a fallback ready. His connection to the President stays a mystery, and Gyro suspects he knows nothing of Valentine's real intentions.

Once Valentine locates the head of the Corpse and moves to take its last piece, the left eye, from Diego Brando, he ambushes Johnny Joestar and deceives Diego and Wekapipo with his own Stand. D-I-S-C-O is peeled off to stop Gyro from reaching the others. Skipping any introduction, he switches on Chocolate Disco, a brace that spreads a net-like grid over a patch of ground; anything he holds can be hurled to exact points inside that grid. When Gyro throws a Steel Ball at him, the grid bends its path and sends it back into Gyro instead. He next scatters nails and reactivates the field so they pin Gyro's leg, then smashes bottles of powerful acid he means to steer onto his target. Realizing he cannot overpower the Stand itself, Gyro turns to fooling its user, exploiting an air lens formed by the heat off his spinning Steel Balls to scramble D-I-S-C-O's read on his position. Beaten and refusing to reveal a word about Valentine's plan, he is finally knocked unconscious.
