Sneak Army

The Sneak Army (スニークアーミー) is a black version of Stealth Sneak that must be fought in the 34th and 4th seeds of the Hades Cup. Like Stealth Sneak, Sneak Army is a giant chameleon-like Heartless that's capable of turning invisible.

While it does appear in the first Kingdom Hearts, it is simply called Stealth Sneak, and is only given a name and journal entry in Kingdom Hearts Final Mix.

Design
The Sneak Army is a bipedal lizard resembling a chameleon. It has a dark steel blue body, with five short spikes along its back. It often stands hunched over, holding its arms out in front of it. Its entire upper body is covered in stripes of various shades of black and grey, reminiscent of camouflage clothing. Its hands and feet have four toes each, two in front and two in back, with black claws. Its prehensile tail is curled up behind it in a spiral. It has a mouth lined by short, pointed teeth, a pink tongue that can extend to surprising lengths, and large yellow and orange eyes with small black pupils. It also has a large, black horn on the tip of its snout. Its Heartless emblem is on its chest.

The Sneak Army shares the former part of its name with the latter part of the Stealth Sneak, emphasising that both Heartless are of the same family. "Sneak" means "to hide", referencing its ability to become invisible, and "Army" references the camouflage pattern present on the Heartless.

Strategy
Apply the same strategy as you did for Stealth Sneak, but take more caution; it tends to switch places more frequently than its predecessor, so lock on to it. You are also recommended to use Aeroga to double the damage you deal to the enemy.

The Sneak Army shoots a ball of light from its hands, and you can evade this by simply jumping. It also fires white lasers from its eyes, though they do not have homing properties. You can either stay far away from it, or attack it directly at the center of the Sneak Army's head (not the sides, because you will receive damage). Repeat these steps accordingly and you will have it down in no time.

Trivia

 * Curiously, when a Sneak Army is defeated it does not fade into darkness like other Heartless do. Instead, it collapses to the ground and twitches.
