Ed is one of the secondary antagonists of The Lion King.
In A Tale of Two Brothers, Ed corners a baboon named Rafiki at Five Stones, with the help of his two companions, Banzai and Shenzi. But before the hyena trio can kill the baboon, Ahadi, the king of the Pride Lands, stops them and tells them that they're not allowed to hunt for sport. After a bit of protesting, Banzai and Shenzi submit to him, and Ed giggles, covering his face with his paws. Later, the hyena trio meets up with Taka. They try to be dramatic and scare him, but Taka isn't impressed, and tells them to stop with all the drama. When things get down to business, Taka warns the hyenas that Ahadi was looking for them, since they had been causing a lot of trouble lately. Banzai suggests moving to the mountains, but Shenzi and Taka yank at his whiskers, and Ed snickers when he lets out a yelp of pain. Taka then says, "No wonder you begged me to join your little gang." Banzai and Shenzi protest, and Ed nods his head in agreement. But Taka lets out his claws, and the hyenas reluctantly submit to him. Later, when Banzai and Shenzi asks why Taka wasn't hunting with Ahadi, the young lion gets angry at them, and corners them up against a tree. While Banzai and Shenzi try to make up excuses, Ed just giggles. But they manage to smooth Taka's fur by giving him a plan to make Mufasa look bad. When Taka begins to ponder the idea, Ed joggles his head in agreement. When Taka leaves, he promises to bring them food later, then disappears into the Savannah.
In Friends in Need, the hyenas appear at the beginning again, where they are preparing to boil Zazu in the Elephant Graveyard. Until a teenage Mufasa passes by, and scares the hyenas away.
