Mini-Boss
A "Mini-Boss" is a term commonly used in video games to describe a character that is stronger than regular enemies but not as powerful as the main boss. Mini-bosses often serve as a challenge for players, requiring them to use strategy and skill to defeat them. They typically appear at key points in a game, providing a sense of progression and accomplishment.
In many games, defeating a mini-boss can reward players with valuable items, experience points, or access to new areas. Mini-bosses can vary in design and abilities, often reflecting the themes of the game or the environment in which they are found, such as fantasy creatures or mechanical foes.
