Sneak Army

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.

It does appear in the first Kingdom Hearts, however, it's only given a name and journal entry in Kingdom Hearts: Final Mix. It should be noted that the introductory texts at the beginning of the Hades Cup seeds involving the Sneak Army in Kingdom Hearts refer to it as Stealth Sneak.
