The Ghost of Scar

Scar's Ghost is a manifestation of Scar's lingering darkness that appears in Kingdom Hearts II. It stalks Simba, due to the unease in his heart about taking his place as ruler of the Pride Land.

Kingdom Hearts II
''This phantom appeared in the Pride Lands after Scar's death. It seems to have been created from the evil in Scar's heart, and it preys on the weakness in Simba's.''

''The ghost may be a sign of more evil to come. Simba still can't seem to believe in himself, and the other lions are getting more and more worried.''

Kingdom Hearts II
Sora, Donald, and Goofy return to the Pride Lands, only to find Simba being plagued by Scar's Ghost. Simba's fear and uneasiness while facing Scar's Ghost make him the laughing-stock of Shenzi, Banzai, and Ed.

Sora tries to find out the cause of Simba's fear; Simba only replies that he is unable to follow the footsteps of his father. Sora tries telling Simba that he just has to be himself, but to no avail. After failing to talk things out with Simba, Sora and company leave in a huff; they hide behind a log in the Oasis and, perhaps as a method of coercion, create a replica of Scar's Ghost to help Simba gather his courage. After they successfully helped Simba to regain his composure, Nala, Timon, and Pumbaa are confronted by Scar's Ghost, and Simba chivalrously tells the Ghost to disappear. Soon after, all of the Ghosts gather together, forming a giant Heartless known as Groundshaker.

Appearance
Scar's Ghost shares the same appearance as Scar, except with dark entrails and a dark haze about him.

Strategy
Scar's Ghost appears in all of the areas in the Pride Land, but never attacks. Instead, it chases Sora and his friends if they run away and circles them if they stand still. Undoubtedly it has the lowest amount of health of any enemy - one HP - and will perish with one hit.
