King Julien II was a mentioned character in All Hail King Julien. He was the second king of Madagascar, and married a royal cow whom he may have eaten for dinner that same night. He is also known for his allergy to gecko milk, where if he drank it, he was turned into a beast known to the public as the Night Creature. He was killed by Grandma Rose.
He is King Julien's ancestor, and therefore looks much like his descendant. However, when drinking Gecko Milk, he transformed into a large muscular beast.
