CREEPERS (MINECRAFT)
Sort of an obvious choice for a list such as this one. Creepers have been the bane of many Minecraft players’ existence for years, and it’s easy to see why. These self-exploding enemies can destroy long stretches of hard work in a matter of seconds, and what makes it worse is that, so often, you don’t even see or hear them coming. When you do, often, it’s all too late.
