Nana (Madagascar)

Nana is a character from Dreamworks Madagascar franchise who first appears as a minor comic relief character in the first installment. She is an old lady who is usually shown comedically beating up protagonist Alex the lion and calling him a bad kitty. She returns in the sequel Madagascar Escape 2 Africa where she at first appears to be a mere comic relief antagonist (much like her role in the first movie) but actually turns out to be the films main antagonist when she stole the animal reserve's water supply.
