Suzi Q

Suzie Quatro (スージーQ Sūzī 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
She appears briefly in Part 3 rushing to her daughter Holy's side when the latter falls deathly ill. When Joseph goes to fight Dio Brando, she is left in the cares of Roses until he returns. Along with Roses and a Speedwagon Foundation member, she decides to visit her daughter, but seems to be unaware of Holy's sickness. When Roses grows courage to tell her the truth, Suzie says she already knows and he shouldn't worry about it.

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.
