Granny Grim is the grandmother of The Grim Reaper. Like her grandson and the rest of her family, Granny Grim is an 'undead, talking magical skeleton' and has dreadlocks growing out of her skull. Also like her grandson, Granny Grim speaks in a Jamaican accent. Granny Grim is the mother to either one of Grim's parents, and the mother-in-law to the other. Granny Grim may also possibly be the sister of Kali, Grim's great aunt--but the relation is never verified in the series run, only by the virtue of their relation to Grim.
