Sara is a character created for Sonic the Hedgehog: The Movie. Her father is the President and she apparently is a cross between a human girl, a cat, and a monkey. The identity of her mother is best kept unknown.
Why does she exist?
1: To satisfy the production company's fetishes, and
2: To prevent the movie from looking homosexual.
What does she do?
Well she's basically just a damsel in distress who Dr. Eggman captures and wants to marry and have babies with (seriously). She cheers Knuckles on by kissing him, Tails accidentally feels her up, and Sonic accidentally sees up her skirt (through Metal Sonic). As you can see, she's not a very flattering depiction of women at all.
- NO! NO! DON'T LOOK THERE, YOU PERVERT!
- THANK YOU, MR. MOLE!
- I WOULDN'T MARRY YOU IF YOU WERE THE LAST MAN ON EARTH!
