Darkballs are enemies from Kingdom Hearts.
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 Atlantica, Neverland and Traverse Town. It closely resembles the Shadow Stalker, because that's also a black, round, pureblood Heartless with yellow eyes and three appendages.
A Darkball is one step up from a Gigant Shadow and one step down from an Invisible.
