basically has the same functions as regular enemies (where they are picked at random) however, only one is picked per run. Mini-bosses will make all other enemies pause momentarily (or will make certain enemies active to help them out) a miniboss will appear during the mid-point of the night and will be harder to counter than an actual enemy. They will continuously attack you until a few (in-game) hours pass and then they leave for the rest of the night. All enemies that were activated before will restart whatever they were doing from the start (so like if Alton was on camera 5 he'd go back to the blue room) so you have time to readjust. with the existence of "mini-bosses" you may think there are actual bosses... which is true but they are always guaranteed no matter what. (regular runs may not have an actual boss but cruel runs will prob have one)
