The Hyenas (The Lion King)

In one of Disney's finest rip-offs to date, The Lion King hyenas were the mangy lowlifes who tried to kill Simba, assisted in the assassination of Mufasa and utterly destroyed the Pride Lands after helping Scar take over as king. Jesus, what is those assholes' problem?

Hyenas, chief douchebags of the Serengeti.
They want something to eat. That's their problem, and it's only a problem because Mufasa banished them from the Pride Land and forced them to live in an elephant graveyard, which is no place to raise a child, hyena or otherwise. We never know why they were banished to the Pride Slums, leaving us to assume Mufasa's unedited explaination of the Circle of Life went something like this:
Mufasa: Everything you see exists together, in a delicate balance. As king, you need to understand that balance, and respect all the creatures-- from the crawling ant to the leaping antelope.
Simba: But Dad, don't we eat the antelope?

Simba: Wow... Say, Dad, where do the hyenas fit into the great Circle of Life?
Mufasa: Ugh, the hyenas. No, f#@k those guys.
Simba: Yeah, that's fair.
That's the only way to explain how Scar got an entire army of these animals behind him with such dissident slogans as "Stick with me, and you will never go hungry again!" Scar wasn't promising them unlimited power, just the ability to eat and function as members of society. The hyenas were pissed because the oppressive lion regime had reduced them to second-class citizens, hoarding all the pie for themselves.

Hooray for racism!
