Gia is one of the main characters in Madagascar 3: Europe's Most Wanted. She is jaguar and is a circus performer. She is also the main love interest and later girlfriend of Alex The Lion.
In the film, she is a performer for Circus Zaragoza. She acts as a moral compass for the circus and protects her friends but also opens them up to new experiences. She is the one who allows Alex and his friends to board the circus train to escape from Captain Chanel DuBois and her men. Alex and his friends lie about being circus performers, and she tries to convince Alex to teach her to do trapeze. She ends up doing a trapeze act with Alex, which they call "Trapeze Americano."
Eventually, she and the rest of the circus find out that Alex and his friends lied about being circus performers. She is heartbroken by this and the two parties go their separate ways. Later, however, when she finds out from the penguins and King Julien that DuBois had captured Alex and his friends, she and the rest of the circus rush off to rescue them.
In the end, Alex and his friends stay with the circus, and so presumably, she and Alex get back together.
- She is voiced by Jessica Chastain, who also played Beverly Marsh in It: Chapter Two.
