[General video games] Why are "minibosses" usually bigger than regular bosses?

I understand they're called "mini" because they're just minions of the regular bosses, but if they're bigger, why aren't they stronger? Why aren't they the bosses?

Why are you able to beat them all when you aren't biggest? You're making the assumption that being bigger inherently makes you more powerful. That doesn't seem to be the case. 

It may be because these larger mini-bosses rely more on their size than skill, where as the smaller guys train harder. 

Maybe the big guys just happen to be far less experienced and would eventually ascend to the leadership position if they didn't get killed off.
