The Darkball is a Pureblood Heartless that appears in Kingdom Hearts, Kingdom Hearts Chain of Memories, Kingdom Hearts coded, Kingdom Hearts Birth by Sleep Final Mix, Kingdom Hearts χ, Kingdom Hearts Dark Road, and Kingdom Hearts Melody of Memory.
The Darkball, true to its name, has a spherical body that is pitch black and streaked with dark blue. Its glowing, yellow eyes are rather small. The inside of its mouth is blue, and the mouth itself is a jagged, toothy opening. This Heartless has three thick, black and blue tentacles with frayed, pink tips sprouting out of its body; two are on its top, and one is on its underside. The Darkball closely resembles the Shadow Stalker from Kingdom Hearts II, although the Shadow Stalker has a smoother appearance overall, and several smaller appendages.
The Darkball's name reflects its spherical shape and its status as a Heartless, a heart corrupted by the darkness.
Darkballs are relatively easy Heartless to defeat; their attacks do little damage, they attack infrequently, and their HP is low. These Heartless teleport from one place to another in a way similar to the Invisible.
