Chaotic Evil: Every villain is out to cause chaos, death and destruction.
Complete Monster: The Writer is responsible for all the bad things that happen in the story, and is the true villain of the entire series. The Writer created the world Simba and his friends lived in, and had caused every evil act in that world. The Writer also created all the other villains in the story. The Writer's creations included Scar, as well as evil versions of Timon and Pumbaa who drain the souls of cubs. He had always been trying to kill Simba and his friends or ruin their lives for fun, and at the end of the series, he goes into the world himself to kill Simba and his friends so he can take over and rule the world for eternity as he destroys thousands of lives for his own amusement.
Creator Worship: A lot of the fans really appreciate the series and the effort that goes into it. Recursive fan fiction, artwork, audio recordings and even music have come about as a result of the series.
Ear Worm: Hago's version of 'You're Only Second Rate' is pretty addictive. Some fans even call it better than the original Disney version. See Awesome Music above to listen to it.
Genre Turning Point: Before this series came along, most stories featuring Simba and Nala were focused purely on cute, fluffy romance. Once the series came around, stories involving these characters became much more action-packed.
Simba, Nala and Haiba, tiny cubs, are consistently able to overpower and sometimes kill fully grown lions. These battles are consistently played up as ultimate showdowns. It's already ridiculous the first time Simba fights Hago, but you'll be rolling in the aisles when it's "professional assassin" and supposed Lightning Bruiser Interceptor's turn.
All the times the cub characters are described grabbing someone and putting them on their backs. They're just cubs; by all rights, they shouldn't have the strength to carry someone, even if it is another cub. And just how are they putting them on their backs if they are mostly anatomically-correct lions?
Nausea Fuel: Tara's exploding guts landing on Simba, Nala, and Haiba at the end of My Immortal. It's so disgusting that it moves Simba to utter the following line:
Haiba, arguably the most popular character of them all, dies in The End. However, he comes back.
Unpopular Popular Character: Every single TLKA fan loves Haiba to death, but not everyone in the series takes too much of liking to him. Even Simba and Nala are disturbed by his romantic actions sometimes.
What Do You Mean, It's Not for Kids?: The series is rather dark and violent, especially as it goes on, and even features Scar, the simultaneously loved and despised villain of the original film, raping a teen lioness and contemplating doing the same to Nala, a cub.
