Darkball

The Darkball (ダークボール) is a Pureblood Heartless from Kingdom Hearts and Kingdom Hearts: Chain of Memories.

One of the few pureblood Heartless, the Darkball is an orb of darkness that teleports from one place to another, using a tactic similar to the more intelligent Invisible. One of the Heartless that first appeared in Hollow Bastion, it was later a common sight in every other world (excluding the Awakening). Darkballs have even appeared in the memory version of Destiny Islands in Castle Oblivion.

Kingdom Hearts
''Heartless born purely out of darkness. Their movements are unpredictable, as they often make sudden moves and attacks.''

Kingdom Hearts: Chain of Memories
A Heartless made from the very shadows of darkness.

The Darkball mostly just bobs through the air, but its random weaving and biting are a nuisance.

Abilities
Darkballs are relatively easy enemies, and generally do little damage, thanks to the long pauses and low HP of this variety of Heartless. A Darkball's abilities include:
 * Reducing themselves to a small, purple cloud, allowing them to evade attacks, before expanding rapidly, causing damage.
 * Adopting a 'berserk' state, by which the Darkball rockets around in a restricted area, causing impact damage.
 * A charging chomp attack.

Trivia

 * It closely resembles the Shadow Stalker of Kingdom Hearts II, although the Shadow Stalker has an overall smoother appearance and several smaller appendages.
 * Darkballs are one of the most common enemies in Kingdom Hearts: Chain of Memories.
