1. The Dog

GAME: Duck Hunt (NES, 1985)
That damned dog! It’s one thing to distract us while we’re trying to shoot down some ducks in a bundled game. It’s a whole other problem, though, when our supposed canine companion laughs in our face. A video game pet shouldn't inflict psychological trauma and kill your GOD-GIVEN RIGHT TO SHOOT DEFENSELESS ANIMALS, and it definitely shouldn't spawn a generation of paranoid animal haters. But there you go. Where was Bad Newz Kennel when you needed it?
