All Hail King Julien

When King Julien XII (also known as Uncle King Julien), a very strict and cowardly ring-tailed lemur, is foretold to be eaten by fossa (spelled and pronounced as "foosa"), he abdicates his throne in favor of his nephew, who becomes King Julien XIII, a fun, notorious party animal, who now has an entire kingdom of lemurs to lead on his own. While Uncle King Julien is gone, the new King Julien gets into various troubles in the company of his adviser Maurice, his head of security Clover the crowned lemur, and his biggest fan Mort. All the while, his devious uncle returns and tries to get rid of his nephew to reclaim the throne. Aside from Uncle King Julien and the fossa, Julien deals with other threats like the mad fanaloka Karl and Clover's twin sister Crimson.

At the end of the fourth season, King Julien is dethroned and forced into exile by King Koto and his army but successfully defeats Koto and regains his kingdom in the next season, subtitled Exiled. The fifth and final season takes place after Koto's demise; villains such as Karl and Uncle King Julien decide to give up their evil ways and start a new life. This all leads up to the arrival of Alex on Madagascar (setting the stage of the first film) just as Clover leaves with her husband, Sage Moondancer, on their honeymoon.
