Lisa Lisa

Lisa Lisa (リサリサ) is a character from Part II: Battle Tendency who also appears briefly at the end of Part I: Phantom Blood. She is Caesar Antonio Zeppeli's mentor and Joseph Joestar's mother.

Early Life
Elisabeth Joestar was the baby Jonathan Joestar saved at the end of series 1 and gave to his widow Erina to raise. She was subsequently adopted by the hamon user Straights, and learned the art of hamon from him until her 18th birthday. As a young adult, Elisabeth eventually married George Joestar II, and they had one child. George, unfortunately, had no hamon powers, and was killed by a zombie who had served Dio Brando. Elisabeth murdered her husband's killer and burned him to ash, but he happened to be a high-ranking military official. In order to avoid retaliation, the Speedwagon Foundation helped her to erase all evidence of her existence.

Battle Tendency (1938-39)
Under the name Lisa Lisa, she first appears as a mysterious Hamon user whom Joseph meets in Venice. She soon reveals herself to be Caesar's mentor. She trains Joseph in the ways of hamon and joins in the fight against The Pillar Men as a powerful hamon user in her own right. It is eventually revealed that she is Joseph's long-lost mother, despite her youthful appearance. She is gravely wounded in her one-on-one struggle with Cars, but manages to survive. She later tells Joseph her relation to him personally, at his own funeral. She eventually remarries to a Hollywood screen writer, and may have died between the end of series 2 and the beginning of series 3. It should be noted, however, that Joseph talked to her about the Joestar birthmark right after discovering Dio's resurrection, putting her in her mid-to-late 90's by a presumed time of her death.

Trivia

 * The character Rose from the Street Fighter series is based on Lisa Lisa. Rose's outfit is almost identical to Lisa Lisa's, and she also channels her "Soul Power" into her scarf to fight. One of Rose's alternate costumes in Street Fighter 4 is Lisa Lisa's outfit.
 * Notably, Lisa Lisa also bears some resemblance to her master Straights.
