Aslan, King of Narnia
The Lion Aslan, King of Narnia, is caught and killed by the White Witch, but comes back to life and defeats her. This is what happens in C.S. Lewis's famous book: The Lion, the Witch and the Wardrobe (1950), part one of his The Chronicles of Narnia series.
It is written as a children's book, but many adults like to read it too. The text is not available on the Internet, but there are a lot of C.S. Lewis sites. One of them is:

The Cowardly Lion
Can Lions be cowards? In The Wizard of Oz by L. Frank Baum the King of Beasts is presented as the Cowardly Lion. All animals in the forest expect him to be brave, but this poor Lion is a coward. He says: "I learned that if I roared very loudly every living thing was frightened and got out of my way. Whenever I've met a man I've been awfully scared; but I just roared at him, and he has always run away as fast as he could go. If the elephants and the tigers and the bears had ever tried to fight me, I should have run myself."
