D-I-S-C-O

Disco is a minor charachter featured in Part VII: Steel Ball Run. He is portrayed as a villan and an enemy of the protagonists.

Story
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 and tricks Diego and Wekapipo using his Stand's power. While Valentine confronts them, Disco his sent to take care of Gyro, in order to prevent him from helping Johnny and the others.

Disco skips presentations and immediately activetes 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 isn't able to beat Chocolate Disco's power, he will try to trick its user instead: by creating an "air lens", thanks to the Stell Balls' rotation, he manages to confuse Disco about his actual position.

Unable to hit Gyro, Disco is defeated, however, he won't say a thing about Funny Valentine's plan. Gyro eventually knocks Disco out, and goes investigating about what happened to Johnny.

Appearance/Personality
Disco is a tall slim man, with medium-lenght curly dark hair, similar to Magenta Magenta's. He possess a long coat and wears his 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, but Gyro believes him to know nothing about Valentine's plan.

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)
