D-I-S-C-O

"Chocolate Disco. That’s my ability’s name. Chocolate Disco. That’s all I’m going to say. I’m done. That’s all. (「チョコレイト・ディスコ」. オレのこの能力の「スタンド名」だ. 「チョコレイト・ディスコ」. ただのそれしか言わない. 以上で終わりだ.)"

- D-I-S-C-O

D-I-S-C-O  (ディ・ス・コ) is a tertiary antagonist featured in the seventh part of JoJo's Bizarre Adventure, Steel Ball Run, specifically in the "Chocolate Disco" story arc. D-I-S-C-O is the last of the assassins sent by Valentine. He confronts Gyro, separating him from an injured Johnny, near, Philadelphia. He is a Stand User, wielding the gauntlet-like Chocolate Disco.

Appearance
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. Shaved beard and mustache can be spotted around his face as well as blue eyes.

He wears a long coat similar to the ones worn by the police officers from the 18th century; wearing his Stand Chocolate Disco like an armband on his left forearm as well as wearing a handcuff for a belt.

Personality
D-I-S-C-O has a rather expressionless face and personality. He is very quiet, speaking only to reveal his Stand's name. He doesn't speak more than necessary because of how the song's name is repeated throughout Perfume's "Chocolate Disco".

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.

Stand
D-I-S-C-O's Stand is Chocolate Disco. It can create a grid he may project over a limited space in front of him wherein he maintains virtually complete control.

History
In Philadelphia, 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.

As Gyro reaches a corner of a building, Valentine and D-I-S-C-O surround him from both sides. Gyro spots D-I-S-C-O but hears gunshots; wanting to help Johnny, Gyro tells D-I-S-C-O to stand still and the agent complies, before activating his ability as soon as Gyro turns his head. With his Stand Chocolate Disco, D-I-S-C-O makes a grid appear on the ground. While Gyro is shocked to glimpse Wekapipo hiding near his horses, Gyro must focus on the enemy. He throws a Steel Ball at D-I-S-C-O, but it is then teleported above him and Gyro is hit by his own Ball. Gyro tries to run towards D-I-S-C-O, but the agent makes nails fall on Gyro, wounding his leg.

D-I-S-C-O then takes bottles of acid out of his pocket, intending to douse Gyro with the acid. Worried, Gyro throws his Steel Balls, but D-I-S-C-O teleports them again. However, this time, the Ball misses Gyro. Surprised, D-I-S-C-O attacks again but misses too with his nails and acid. Suddenly, a hand with a Steel Ball appears near him. Gyro reveals that he has created a zone of high pressure that refracts the light and prevents D-I-S-C-O from knowing Gyro's location. Desperate, D-I-S-C-O takes out a gun but the Neapolitan quickly knocks out the agent.

Trivia
