Suzi Q

Suzie Q is a minor character featured in Part II: Battle Tendency and Part III: Stardust Crusaders. She is portrayed as an ally of the protagonists.

Personality
Suzie Q is a slightly ditzy girl who worries for her friends. Evidently this carefree personality has not diminished even in the events of Stardust Crusaders, when she is shown enthusiastically recording her sightings in Japan on a camcorder when on a trip to see her daughter.

Battle Tendency
She is introduced as the female assistant to Lisa Lisa. When she first appears, she is taken over by the remains of ACDC and attacks her friends. Thanks to a combination attack by Caesar and Joseph, she is saved with only minor injury. She marries Joseph in 1939.

Stardust Crusaders
We see her briefly in part 3 rushing to her daughter Holly's side when the latter falls deathly ill.

Diamond is Unbreakable
She is mentioned as being very upset about finding out about Joseph's illegitimate child Josuke. She also flies into another rage upon seeing Joseph introduce Shizuka to the family, assuming that he fathered another illegitimate child.

Trivia

 * Though the common romanization of her name is "Suzie Q", JoJo 6251 lists her name as "Suzi Quatro".
