I Guess The Lion King is Somewhat a Part of the CEM, as Well.

There is a race of beings at the beginning of the universe known as Immortals. And in one of the four Immortal realms, there are two characters named Mufasa and Scar. They both are humans in appearance, but they also each have a special power that no one else shares (except for possible offspring of both characters): The ability to shapeshift into a lion.

HOWEVER. Most fictional worlds included in the CEM will have their own book. The Lion King will not.
