Sherry Polnareff

Sherry Polnareff (シェリー・ポルナレフ) is Jean Pierre Polnareff's deceased younger sister.

History
Sherry was raped and murdered by J. Gail, leading to Polnareff's desire to seek her killer to exact revenge. She seemed to have gotten along well with her brother, as he frequently carries her picture with him.

Stardust Crusaders (1987)
Eventually, Sherry's brother manages to avenge her by battling and ultimately killing J. Gail. Later, Polnareff asks Judgment to revive her after the stand grants him a wish. Instead, the stand manifests a golem that looks and sounds exactly like her, but attacks Polnareff when he lets his guard down and gets close enough. The golem is ultimately destroyed when Judgment throws it at Magician's Red as a diversionary tactic.

Trivia

 * In Manga, Sherry only appears in Polnareff's flashback, later in photo. In Anime, she is seen wearing her school uniform and Pantyhose.
