Alex

At the Central Park Zoo, Alex is the star attraction. On Madagascar, away from his usual steaks, hunger makes him hallucinate his friends as steaks and lunge. Frightened of himself, he runs to the fossa's territory. Marty follows him and, when the fossas attack, Alex beats his instinct and drives them off.

Alex and his friends try to fly back to New York in a balloon at Christmas. The lemurs mistake them for a red goblin who visits the island every year, and Alex shoots Santa down. The attempt to get home turns into a mission to deliver presents.

In Africa, Alex reunites with his parents. He was taken as a cub from a reserve in Kenya, and was named Alakay, the young lion who preferred dancing to fighting. He loses a fighting rite, but saves his dad by dancing for tourists who remember him from the zoo.

In Monte Carlo, Alex and the gang escape Captain DuBois and hop aboard a European circus, pretending to be American. Alex falls for Gia, teaches her the Trapeze Americano and ends up choosing to stay. At the end the group officially joins the circus, where it finds its place.

Ben Stiller voices Alex. In the second film, his son, Quinn Dempsey Stiller, voices baby Alex, named Alakay.
