King Julien appears in The Penguins of Madagascar regularly, often noisily and unintentionally annoying Skipper and pretty much everyone. He is the self-proclaimed "King of the Zoo" no doubt due to his former king status on Madagascar. Only Mort and Maurice truly believe and respect him as their king, the rest just show up to his "proclamation of royal decrees." Julien is proven to be a worthy ally in most episodes, since it is he who sometimes saves the day for the penguins (like in "Dr. Blowhole's Revenge"). Julien hates having anyone touch his feet, such as passing a royal decree that anyone who touches his feet would be banished from his kingdom (the zoo). When the sewer rats went to the zoo and tricked the Penguins out of their home, Julien decided to play for the Penguins in a game of Hockey to try and win their home back. They were losing until one of the rats touched his feet, after that he lost it and beat all of them on his own.
King Julien appears as a playable character in every Super Brawl game, with the exception of Super Brawl 3. He first appeared in Jingle Brawl as an unlockable character, but has been a default character in Super Brawl and the other games. When Julien uses his special attack Mort will jump up in the air and then kick diagonally down to the opponent. When the special bar is fully charged and Julien uses his special attack he will make some dance moves damaging the opponent if he is near.
