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 Dark Ball 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.
