Black Guard

The Black Guard are enemies that appear in Kingdom Hearts 3D: Dream Drop Distance. These characters originated in the Disney film Tron: Legacy. They are vicious computer programs that were reprogrammed by CLU to serve as his main enforcers, so they demonstrate no individuality or emotion beyond following CLU's orders. They appear throughout The Grid as generic enemies.

Kingdom Hearts 3D: Dream Drop Distance
Sora encounters four Black Guards after chasing a Recognizer. They demand that he state his handle, but Sora states that he has no handles and introduces himself. However, Sora's name is not recognized as a handle and he is mistaken for a stray program. The guards then grab him and pull him to the Recognizer, but Sora breaks free and escapes.

Some Black Guards later find Riku and, mistaking him for a stray program, attempt to force him onto a Recognizer, but he brushes them off and boards willingly. They later race Riku in a Light Cycle race, but are easily defeated.

Appearance
The Black Guards wear black, skintight suits lined with circuitry, and uniform, featureless helmets. The orange hue of their circuits indicates that they serve CLU. They are also equipped with batons which they carry on their arms and are used to expand their armament with various additional weapons such as a sword, or staff, their backs can sprout Tron chutes to allow flight, and can carry grenades which they keep within their thighs.

Origin
The Black Guards debuted in Tron: Legacy. Like Tron, they were all reprogrammed to serve as CLU's army and henchmen, but they can act like normal programs when not on duty, as several guards are seen relaxing in the End of Line club. Many appeared on the Rectifier during CLU's speech about invading the userworld to perfect it. Flynn managed to reprogram one (by tampering with his Identity Disk, then hitting him in the head) to allow him to steal a Fighter Jet. It's unknown what happened to the Black Guards following the destruction of the Portal and CLU.
