King Julien

Julien and the lemurs welcome the castaways hoping Alex will keep the fossa away, despite protests from Maurice, the adviser, who distrusts a predator. When Alex goes mad with hunger and starts seeing everyone as steaks, the lemurs panic.

In the Christmas special, the lemurs prepare to give gifts to the king for Julianuary. When Santa crafts toys for everyone, Julien gets annoyed that the focus isn't on him and decrees the lemurs' gifts are his. Alone with the pile, he gets sad, until Santa suggests giving a gift too.

At the African reserve, Julien gives advice that helps Melman confess his love for Gloria. He also suggests offering a sacrifice to the volcano to bring the water back, which nearly ends badly for Melman.

In Rome, Julien falls for Sonya, a brown bear in the circus. Later he breaks up with her, then returns to the circus to say his friends need help. He reconciles with Sonya, and the circus animals go to rescue the gang.

In the penguins film's final scene, Dave's machine is used to turn Private back to normal, with Mort as the power source. He looks the same, but can now swallow King Julien in a single gulp.

Sacha Baron Cohen voices King Julien in the films. His cover of "I Like to Move It" became a franchise theme. In the special Madly Madagascar and the series All Hail King Julien, the voice is Danny Jacobs.
