What are some sidekicks in video games that you think are useless, who serve no purpose in the game other than to annoy you?

For example: There is this game called Princess Tomato in The Salad Kingdom for NES. The main character gains a sidekick very early in the game and he sticks by your side for the entire game. I find he’s basically useless, the most he does is drop all our stuff at the end of the level. Very few times he’ll have helpful advice and insight on what to do next.
