Chocolate Disco

Chocolate Disco belongs to the killer D-I-S-C-O and appears in Steel Ball Run. It takes the plain form of an armband fitted with a grid of pushable keys arranged in eight columns, each cell tagged with a letter and a number like map coordinates. In color pages the gauntlet and its grid are a yellow-brown. As a tool-type close-range Stand it deals no damage by itself and leaves its user helpless in a straight fight, so he leans on ordinary objects he carries to do the actual harm.

The moment D-I-S-C-O brings the Stand out, a lettered-and-numbered grid spreads from his feet across roughly twenty feet of ground ahead of him. Tapping a key on the armband instantly yanks any flying object or projectile to the matching square, where it drops. He uses this to bring dangerous things such as nails or acid down straight onto a target, and to protect himself by warping incoming attacks back toward the attacker, which puts Gyro Zeppeli's Steel Balls at a real disadvantage. The catch is precision: he has to call the correct coordinate, and a miss leaves him wide open at close quarters. Araki based the grid concept on the board game Battleship.

As the only wielder, D-I-S-C-O deploys Chocolate Disco against Gyro Zeppeli, teleporting nails, acid, and Gyro's own Steel Balls around the battlefield.
