In video games, a boss is a significant computer-controlled opponent. A fight with a boss character is commonly referred to as a boss battle or boss fight. Bosses are generally far stronger than other opponents the player has faced up to that point. Boss battles are generally seen at climax points of particular sections of games, such as at the end of a level or stage or guarding a specific objective. A is a boss weaker or less significant than the main boss in the same area or level, though usually more powerful than the standard opponents and often fought alongside them. A (sometimes 'secret' or 'hidden' boss) is generally much more powerful than the bosses encountered as part of the main game's plot and is often an optional encounter. A is often the main antagonist of a game's story
