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 series.

The yokai took on the form of a very elderly woman with reddish brown wrinkled skin, long thick white shaggy hair, wide eyes with a yellow sclera and were stuck looked to the sides. When possessing her targets, she has her victims transform into a mirror image of herself, albeit with a large mouth with teeth that is capable of biting off body parts.

After having her consciousness extracted from Okarun, Turbo Granny is forced to inhabit a maneki-neko doll.

Turbo Granny is a yokai that acts cruel, sadistic, and is extremely foul-mouthed. She is also rather somewhat vulgar, as she offered Okarun a chance to suckle on her breasts in exchange for consuming his family jewels. Since she possesses impressive running power, Turbo Granny takes great pride in her speed and refuses to be underestimated. When challenged to prove herself, she is not above using trickery to get her way, having been deceitful with Okarun and Momo in their game of tag by counting irregularly. Despite her negative attitude, she is revealed to have a compassionate side, as Seiko stated that Turbo Granny would most commonly wander off to spirits of girls who died tragically in order to comfort them, which was the reason as to why she fused with the Earthbound Spirit Crab within Shono City.
