Black Sabbath

Black Sabbath is a Stand, a supernatural entity with unique abilities, bound to its user's will. It possesses a menacing appearance, evoking the imagery of the Grim Reaper, complete with a dark, cloak-like body and a ghastly face. Black Sabbath is not capable of speech but its actions convey a sense of unwavering loyalty to its user, executing orders without hesitation.

Personality-wise, Black Sabbath is devoid of a personal sense of morality or ethics, acting solely under the commands it receives. It operates with a mechanical precision, showing neither mercy nor hesitation in fulfilling its designated tasks. Its presence is often associated with a sense of foreboding, as it carries out its duties with a ghostly silence and efficiency.

Black Sabbath is involved in testing the abilities of others, serving as a gatekeeper to ascertain their worthiness. It manifests under specific conditions, utilizing its unique abilities to challenge those it encounters. Through its actions, it plays a crucial role in the unfolding events, acting as both a catalyst for growth and an obstacle to be overcome.
