Mid-boss

Mid-bosses (also known as Mini-bosses) are enemy characters that are stronger than regular enemies but not as strong as bosses. Kirby usually has to fight them in the middle of a stage before he can continue on (which is probably where they get their names from). Usually, during a fight with a Mid-boss, Kirby cannot leave the battlefield and thus must fight them to progress.

Fighting Mid-Bosses
Most Mid-bosses, with the exception being the Meta-Knights have a health meter that must be depleted before they are defeated. They also have at least one attack that can be inhaled and spit back at them (this is the only way to beat them without a copy ability).

Copy abilities from Mid-bosses
When a Mid-boss is defeated it lies on the ground for a few seconds before exploding. During this time Kirby can inhale them and gain their ability. All Mini-bosses have copy abilities and some copy abilities can only be collected from a certain mini-boss (Like the Ghost Ability).
