Nana Possible
Voiced by: Debbie Reynolds
Kim's paternal grandmother. She was first mentioned in the episode Downhill and made her first appearance in The Golden Years. She was as skilled a fighter as Kim, even more so, having trained in "Pang Lang Quan Kung Fu" in a Shaolin Monastery, became a top aviatrix, and was the first woman to finish the Navy's Basic Underwater Demolition Course (BUDS, also known as S.E.A.L. Training). Kim never knew about this until they were pitted against each other by Drakken.
