If it's Everybody Edits the ones that are hard are the pro ones because once the boss places a red brick a green brick quickly comes a the red brick goes away. In minecraft in the Aether Mod it's ULTRA hard for the one eyed bosses because they just slide around everywhere. There's also a boss that's a some sort of fairy. There's also a fire boss that's SO HARD because it just shoots FIRE BALLS at you but at some point it will shoot a ice ball a you need to use a sword or a bow and arrow and Dodge it at him a WEE LITTLE MAN comes and ATTACKS you. These answers don't really match with the question BTW.

A great many, but Teddy Roosvelt was particularly awkward.
Hero = 8 bosses, Dark = 8 bosses, Last = 2 bosses so 18 bosses in total.
Try hitting them while dodging, and see if that works. They are only hard if you let them hit you, or you're not skilled enough. It is a hardcore game, after all.
