D-I-S-C-O is a tall slim man, with medium-length messy, curly dark hair with a large, rectangular hair clip/accessory sitting on the left side of his head.
He wears a long coat; wearing his Stand Chocolate Disco like an armband on his left forearm.
D-I-S-C-O has a rather expressionless face and personality. He is very quiet, speaking only to reveal his Stand's name.

D-I-S-C-O's Stand is Chocolate Disco; a grid he may project over a limited space in front of him wherein he maintains virtually complete control.
As soon as the president manages to find the head of the corpse, he decides to take the last missing part from Diego Brando: the left eye. In order to do so, he ambushes Johnny Joestar and tricks Diego and Wekapipo using his Stand's power. While Valentine confronts them, D-I-S-C-O is sent to take care of Gyro Zeppeli in order to prevent him from helping Johnny and the others.
D-I-S-C-O skips presentations and immediately activates his Stand's ability. Gyro hears gunshots and rushes to help Johnny. He tells D-I-S-C-O to stand still, but since he doesn't listen to him, Gyro throws a Steel Ball, trying to get rid of him. However, Chocolate Disco changes the Steel Ball's direction, causing it to hit Gyro instead.
D-I-S-C-O's next move is letting some nails fall to the ground: he then proceeds to reactivate Chocolate Disco, so that the nails will hit Gyro's leg, preventing him from escaping the Stand's action zone.
As finishing move, he breaks some bottles containing a very powerful acid: should the liquid hit Gyro directly through the use of D-I-S-C-O's Stand, it would mean death. Fortunately, Gyro understands that, since he is unable to defeat Chocolate D-I-S-C-O's power, he will try to trick its user instead. D-I-S-C-O becomes unable to discern Gyro's position when the latter uses an "air lens" created due to the heat given off by the Steel Balls' rotation. He manages to confuse D-I-S-C-O about his actual position, and D-I-S-C-O is defeated. However, he refuses to say anything about Funny Valentine's plan and is eventually knocked out by Gyro.
- The words "chocolate disco" keeps getting repeated in the song "Chocolate Disco", which is why Araki chose to make D-I-S-C-O not speak any more than necessary, either.
