In the 5th Doctor story, Kinda, we meet a character named Hindle. He acts like a spoiled brat through out the story. I only it is not really his fault. He was mentally unstable due to the Mara's appearance, but still he got on my nervous quite quickly. I got annoyed every time there were scenes with him. I also felt real bad for everyone who had to be stuck with him, especially poor Adric, whom I have a of more soft spot for him than most people.
