D-I-S-C-O

Disco is a minor antagonist featured in Part VII: Steel Ball Run.

Appearance/Personality
Disco is a tall slim man, with medium-length curly dark hair, similar to Magenta Magenta's. He possess a long coat and wears Chocolate Disco like an armband.

Disco has a rather expressionless face and personality. He is very quiet, speaking only to reveal his stand's name. It is unknown which kind of relationship he might have with the president: he might be one of his loyal stand users, though Gyro Zeppeli believes him to know nothing about Valentine's plan.

Synopsis
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, Disco is sent to take care of Gyro Zeppeli in order to prevent him from helping Johnny and the others.

Disco skips presentations and immediately activates his Stand's ability. Gyro hears gunshots and rushes to help Johnny. He tells Disco 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.

Disco'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 Disco's Stand, it would mean death. Fortunately, Gyro understands that, since he is unable to defeat Chocolate Disco's power, he will try to trick its user instead. Disco becomes unable to discern Gyro's position when the latter uses an "air lens" created due to the heat given off by the Stell Balls' rotation. He manages to confuse Disco about his actual position, and Disco is defeated. However, he refuses to say anything about Funny Valentine's plan and is eventually knocked out by Gyro.

Trivia

 * His name is actually spelled DI•S•CO. This is because in the original Japanese version it's spelled DI•SU•KO, as Araki probably wanted to imitate the sound of Chocolate Disco's catchy chorus (CHO•KO•RE•I•TO DI•SU•KO)
