When someone thinks of a boss battle or a boss fight generally it is thought about in referring to video games. A boss battle in a video game is an enemy or a challenge that is far more difficult than any of the enemies or challenges before it. They can be intimidating and scary, and one needs to be prepared to beat them. Though this may seem like a fictional thing, sometimes boss fights can be found in real life.

Sometimes there is a person, a creature, or a thing that is just far more intimidating and frightening than anything seen before. Some of them are genuinely scary, others more tame yet still superior in some way. Reddit's dedicated subreddit /r/BossFight collects all of these terrifying, real-life encounters of bosses found throughout everyday life. They even have names given to them. These 25 figures are ones no one ever wants to meet in a dark alley.
