King Julien the Terrible/Grandma Rose’s long lifespan theory (plus Julien II the night creature)
Disclaimer: This is mainly based on my theory that King Julien the Terrible is the alternate name of King Julien I. (As in he was re-named when re-elected as King and became a tyrant)
I’ll explain my theory like a story because it’s easier! Get comfy because this is a pretty long post!:
King Julien the Terrible, (currently King Julien I) hired a younger Grandma Rose, as his bodyguard, back in the early days of Madagascar. But soon, King Julien I had a son, Julien II. To keep his son safe he locked him away in his hut in the baobab tree, never to be seen by the kingdom. And he didn’t plan for his son to take over as King.
But Julien I wasn’t the best king, and soon there was a revolution (Similar to LALA if it actually worked), and he was kicked off the throne and banished from the kingdom. Julien II took his place. Now Julien I was angry that his kingdom and Rose had betrayed him in favour of his son, and I guess that’s kinda his villain origin story lol.
One day he sent for his son to visit him, to gift him with Gecko Milk, which obviously isn’t actual gecko milk, because that’s not a real thing, but actually an untested poison.
He had planned to poison his son and blame Rose by claiming she was the perpetrator, then reclaim his throne and be seen as a hero. However, this plan was only half successful. Instead of dying, Julien II turned into the Night Creature, and was immediately hunted by Rose, who killed him.
Then only after he was dead did Julien I reveal the antidote and turn him back into the - now dead - King Julien II. Rose was immediately seen as a monster for what she’d done, and banished too. But Julien I didn’t get his crown back. He was also hated for not stepping in sooner and letting the king be killed. This only made him more angry. A 1 year Julien III was put on the throne instead.
Rose was of course, very angry at Julien I, for taking away her respect and making her look like a horrid monster, and it lead to her trapping Julien I in a cave with his tail tied under a rock, then rewriting/altering the history book to make it seem that the creature was just a raving monster and not her beloved king.
Theory time! But about the long lifespan part? Well this is where Mort comes in. He consumes souls as a means to live longer. Well, what if both Julien I and Rose did too, but for different reasons. Julien I to reclaim his throne (and eventually become King Julien the Terrible, and then come back in AHKJ to take over our current King Julien), but Rose did it to train her children and grandchildren to protect their kings.
(Also what if Mort was there on scene with Julien II and remembers watching him die, but he’s too dumb to mention it lol)
Though it’s clear they can still be killed by murder but they can’t die of natural causes. Obviously Julien the Terrible was killed by lightning and Rose died to Victor Wildebeest, and Mort just gets unusually lucky with his survival, and also they probably don’t physically age once they start consuming souls which is why Mort still looks like a child because he has the body of one.
I would probably assume Soul Consumption isn’t practiced now and Mort’s the current only know person still doing it. Otherwise so many other villains would’ve probably tried it by now.
But it’s just a theory. Lemme know if you want to hear why I believe King Julien the Terrible is the same person as Julien I. And also give me your thoughts if you have any :)
