King Julien XII

"I wonder if he's dead yet?"

- Julien XII wondering about his nephew's demise.

King Julien XII is King Julien XIII's uncle and the former king of the lemurs of Madagascar in the Madagascar spin-off, All Hail King Julien, before abdicating his throne to his nephew to avoid being the victim of a grim prophecy.

Role
King Julien XII was a very strict and paranoid ruler who forbade any and all fun activities in an effort to keep from attracting the Fossa to his location. Most lemurs respect him in that he has kept them safe for many years, but the truth is he is a selfish and cowardly individual who is only interested in saving his own life, and according to his nephew, he prefers to rule his kingdom through fear.

But then a fortune-telling chameleon he looks up to named Masacora had a prediction that the king of the lemurs would inevitably be eaten by the Fossa. After offerings to the sky gods and pathetic begging had failed, he then realizes that he can't be eaten if he isn't the one who wears the crown. So he pretends to retire from his position as ruler, passing it on to his nephew, the wild and free-spirited Prince Julien XIII, knowing that he would be eaten instead and that he can take over again once the prophecy has been fulfilled, and runs off for somewhere safe until the deed was done. But unbeknownst to him, Julien XIII had survived the attack, but not without losing a butt chunk to the Fossa (as the prophecy didn't say all of him would be eaten).

After a while of hiding, Julien XII returns and, much to his disappointment, sees that Julien XIII is still alive, and even worse, that he has reformed his former kingdom in favor of fun activities such as water slides (one of which he defiantly turned off while Julien XIII was riding it, making his butt sore). So he tricks his nephew into believing that the Fossa are planning an attack on the lemurs and that anyone can stop them will gain "immortality", so that he would go off into their territory and eventually be eaten while he takes over as king again. During which, he abolishes all of Julien XIII's changes so he can rule with fear again. However, his former assistant and bodyguard, Clover, becomes wise to his treachery and forces him to help her save his nephew. As punishment, he is then suspended by a vine while Fossa attempt to eat him, and then is forced into a Fossa costume while a female Fossa cuddles him much to his horror.
