Gloria is the tritagonist of the Madagascar franchise, and is the love interest of Melman the Giraffe starting on the second film. She is the sole female of a quartet consisting of herself, Melman, a zebra named Marty, and the lion protagonist, Alex. She is voiced by Jada Pinkett-Smith in the entire franchise and, in a flashback in the second film, Jada's real-life daughter Willow as a calf.
The first film never said a thing about her being the love interest of Melman, as it probably wasn't yet decided.
