The Darkball is a type of pureblood Heartless that appears in multiple Kingdom Hearts titles. It typically appears in later areas of the games it is featured in and eventually replaces the basic Shadow Heartless in other worlds.
Darkballs are so called due to their spherical bodies which are as black as night. They have the typical beady yellow eyes of most Heartless and jagged toothy mouths. Three tendrils extend from the body with purple-hued tips.
Darkballs have two methods of attack. One is to whiz around like a deflating balloon, striking anyone foolish enough to get in the way. The other is to charge directly at prey, snapping their teeth constantly as they charge. Darkballs also have an annoying habit of teleporting to evade attacks.
