Gia is the deuteragonist of Europe's Most Wanted. She is generally kind and also passionate about trapeze. Gia speaks with an Italian accent. She defends her circus friends of any threat or insult, an example is when Alex unintentionally made fun of Vitaly, the father-like figure of Gia, which made her instantly mad. Gia is very beautiful and graceful. She eventually seems to develop romantic feelings for Alex after they bond practicing Trapeze. Gia is a trapeze performer in Circus Zaragoza and a very passionate actor on the trapeze, who respects her fellow performers as family and friends. She seems to look at Stefano as a good friend, possibly like a little brother figure, while Vitaly is like a father figure. And she is also known as good-tempered, independent, accountable, gentle, intelligent and athletic.
Gia is a graceful Italian jaguar. She is a little more thoughtful than the other circus performers, as she cares deeply for the circus, and she's beautiful. Alex can’t help but be swayed by her. She acts as a moral compass for the circus and protects her friends but also opens them up to new experiences. In Madagascar 3: Europe's Most Wanted, the beautiful jaguar is always on the lookout to discover something new, and she is Alex's romantic interest in the film. At first like Vitaly, she doesn't trust Alex or his friends, but decides to give them a shot and lets them inside their train and letting them change the circus to "Americano" style.
Gia is first seen with Vitaly the tiger and Stefano the sea lion, all heading to the circus while Alex, Marty, Gloria, and Melman were trying to escape animal control. Gia lets the Four on the circus train after a dazed Alex convinces her that they are circus animals.
She is fooled into believing that Alex is a master circus performer and is falsely following the ways of "Trapeze Americano." When the circus falls into a rut, she doesn't show too much desperation, much like her father figure Vitaly. But when she hears Alex's improvised speech, she is spurred into the "Fur Power" works. Her act with Alex and the trapeze plants herself even closer to the lion. But their cover is blown by DuBois' arrival, although the penguins manage to get rid of her. When Alex and the gang finally admit their true intentions after their London performance, Gia and the rest of the performers are devastated.
When the gang and the circus animals split up in New York, the circus soon falls into sadness, mostly to Gia and Stefano, because they had no one to work with in their acts. Vitaly tries to convince his comrades to work on a solo act, but nobody would. Then all of a sudden, a sedated King Julien pops into the scene and pleads to his bear girlfriend Sonya to take him back and forgive him. While he was begging, Kowalski, one of the penguins, pulls the sleeping dart out of the lemur's tail. It's revealed that DuBois had captured and caged the zoo animals.
Gia was the first to realize their friends were in danger and convinces the rest of the circus animals to help save their zoo pals. In the end, after bringing the blimp to the zoo, Gia swings her way to Alex just in time before he is killed by the poisonous dart that DuBois shot to the lion, and she rescues him. DuBois then pursues to kill Stefano to avenge Alex. Yet before she could kill the sea lion, Gia and Alex come to the rescue, "Trapeze Americano" style, and save Stefano. By the time Alex grabbed Stefano, he also got DuBois. Alex acts quickly and gives Stefano to Gia before DuBois got them both. As Alex and DuBois clash in the air, they were going to land in the penguins' habitat filled with cobras, but Alex whistles for the dogs with rocket skates who rescue them in time, and Alex throws DuBois in his old habitat where Mort sedates her and leaves her there. Gia is taken by Alex with the rocket dogs hanging on his back. Alex then releases a huge mass of balloons up in the air to the children below, then he and Gia smile at each other lovingly before joining the others on the flying circus platform.
Gia is last seen dancing to a mixture Marty's own "Afro-Circus" music video and Julien's "I Like to Move it, Move it" with everyone, including Vitaly, wearing rainbow-striped afros and the circus horses painted with colorful polka dots going across America continuing with the tour.
