In Battle Tendency, Suzi Q is a young woman of average height and build, who keeps her hair tied into a chignon save a few locks standing upward at the side of her head.
During Stardust Crusaders, Suzi has considerably aged and her hair has gone white, she now also wears glasses.
Suzi Q is a slightly ditzy girl who worries for her friends. Her carefree personality did not diminish as she aged, even after the events of Stardust Crusaders, where she is shown enthusiastically recording her sightings in Japan on a camcorder when on a trip to see her daughter. She has a strong faith in her husband, stating how he has always managed to make it through the worst situations and never fail her. She is also shown to have great intuition, at least in her later years, where she was able to deduce that Holy wasn't well and that Joseph had departed to save her, while maintaining a facade of naivete in order to keep everyone's spirits up. While typically very joyful, it appears she does have a reasonable temper, as she was incredibly angry when she discovered Joseph had cheated on her, leading to the birth of his illegitimate son Josuke. She is still forgiving in spite of this, as she forgave him after finding out about the affair and the two did not divorce.
She also shares Joseph's love of pranks and likes to playfully make fun of others, but perhaps not to the same degree as him.
