She apparently died at some point, as Cooler states that he is the only living member of his family.
She is apparently quite powerful, as Frieza noted during his battle with Goku that other than Goku, only his mother and father had ever managed to force him to dust himself off in his final form after a fight.
- Frieza mentions his "parents"/"loving parents" to Goku on Namek in the manga, anime, and Dragon Ball Z: Battle of Z whereas he simply mentions "his father" to Goku in Budokai Tenkaichi 3 and Dragon Ball Z Kai. It should be mentioned that the plural form does not exist in Japanese and thus Frieza's mother is only mentioned in the English dub.
- In Chi-Chi's commentary on First Form Frieza and Final Form Cooler in Budokai Tenkaichi 3, she mentions parents instead of just King Cold alone, stating that Frieza and Cooler's upbringing by their parents is a troublesome story. Chi-Chi also refers to Frieza's mother in King Cold's profile, wondering if Frieza's mother has the same face as Cold.
