Maurice is the supporting character of Madagascar, a major character of Madagascar: Escape 2 Africa, a supporting character of Madagascar 3: Europe's Most Wanted and Madagascar 4: Asia Getaway, one of the five tritagonists of The Penguins of Madagascar series (he doesn't appear in the movie) and the deuteragonist of All Hail Julien.
He is voiced by Cedric the Entertainer in the movies, by Kevin Michael Richardson in the television series, and by John Cothran, Jr. in the video games.
Maurice is King Julien's advisor - not that Julien ever listens to him - and is highly skeptical of his ruler's mad plans. He has a long squirrel-like bushy tail. He lived alongside a tribe of other lemurs and witnessed newcomers to their home: a quartet of zoo animals. Maurice was suspicious of Alex, a lion among them, thinking him to be somewhat dangerous. Maurice expressed this concern during a meeting of the other lemurs and animals of the jungle, but was ignored by Julien. The next day, Maurice took part in the festival in the honor of the newcomers, and shortly after explained the trouble with having Alex the lion around. He knew that Alex was a meat-eater and that he would need to eat steak. It was then that he opted for Alex to leave and go to the carnivore side of the island.
Shortly after, Maurice witnessed Gloria, Melman, and Marty working with a group of penguins overtaking the fossa that were attacking the lemur tribe. Maurice had to concur that King Julien's plan had worked and that fossa would no longer be of any worry. Maurice saw the newcomers out when they decided to leave and was obligated to wave King Julien's arm for him, as the king was tired of waving it.
In the sequel Madagascar: Escape 2 Africa, Maurice does not have much of a prominent role, basically agreeing to whatever King Julien says. He acts like a strict big brother to Mort and knows him so well that in "The Penguin Stays in the Picture" he is shocked to find that Mort only ate half of his popsicle, prompting Skipper to go find him because he suspected Mort went missing, which was right.
He paints well, and in "The Hidden," it is shown that he can speak chameleon. In "The Lost Treasure of the Golden Squirrel" his desire to control an army of Julien manservants is revealed. Despite being overweight, however, he was still able to hold his own when he got into a physical fight with Kowalski and Rico in "The Lost Treasure of the Golden Squirrel."
Maurice returns in Madagascar 3: Europe's Most Wanted. Also he returns in Madagascar 4: Asia Getaway.
