Turbo Granny (ターボババア Tābo Babā?) is a well-known yokai that was previously within a tunnel located at Shono City until her confrontation with Momo Ayase and Okarun. After having her powers sealed within Okarun, along with her consciousness being trapped inside a stuffed doll, Turbo Granny makes a deal with Momo to help Okarun find his kintama in exchange for having her powers back.

In Dandadan, she served as the primary antagonist during the Turbo Granny Arc, but has since become a major supporting character throughout the rest of the series.
