Characters We Never Really Needed

Why do shows feel the need to introduce unnecessary characters? Especially in their final season? Why not focus on the original cast for your swan song? Why bring in the Cousin Oliver? And now, the list...

Characters We Never Really Needed

1. Orko - He-man. Really. He was just annoying. The show had plenty of levity without him. And, what was he anyway. He appeared to be just a floating robe, hat and gloves.
   
2. Scooby Dumb - Scooby Doo. Um, it isn't like Scooby was exactly a rocket scientist.
   
3. Kennedy - Buffy the Vampire Slayer. Final year. A much beloved character has recently been killed off. Instead of focusing on the core group and how this chapter of their lives would end, they brought in a multitude of slayerettes. Okay, I will let that slide. But to bring one of them into the thick of the story AND make her the love interest EVERYONE hated? Why?
   
4. Werewolf Girl - Angel. Once again. Final year. Beloved character loss (well, not so beloved toward the end). Does this show choose to learn from the mistakes of its predecessors? Nope. It brings in a USELESS and thoroughly uninteresting character as love interest. She was so boring, that I don't even remember her name.
   
5. Graup - Harry Potter and the Order of the Phoenix. Baby brother half-giant? What? The book had plenty going on. Evil Defense Against the Dark Arts professor. Quittich bans. AWOL Dumbledore. Idiot Minister of Magic. Rise of Voldemort. Return of the Death Eaters. Tonks. The real Mad Eye. Prophetic dreams. Occlumacy (I misspelled that, I know). Cho and Harry. The DA. So much going on in this book. Graup was just a waste of pages. He didn't really serve any real purpose. He was introduced so close to the end of the book. Why? If he was so great and important, why not work him in earlier? Instead, it is almost like Rowling forgot she was supposed to have given Hagrid a brother. A completely useless brother. Sure, he sort of saved Harry and Hermionie, but that could have been done other ways. I was filled with anger and frustration after reading his tacked on chapter. And then, in the new book, he is mentioned twice perhaps?
   
6. Avery - Felicity. Really? What was the point of Avery? I know they had to give Felicity and Ben some drama, but I think it could have been done better.
   

I am interested to hear your thoughts on more thoroughly useless characters.
