Also, there is a giant bird enemy you fight on top of a mountain that is harder, and has a larger health pool than A LOT of enemies.
It should probably be said that there are bosses in this game, just that after fighting them they will become regular enemies later on. Though *spoiler* enemies that you fight while they are corrupted for a specific situation, could be classified as bosses as well.*spoiler end* *even more spoilers* I would say any Cauldron end enemies are bosses, and a few side quest enemies are bosses. For example, when you are investigating the rock quarry where a huge mole/sand worm machine pops out of the ground, could easily qualify as a boss, as seriously that was a awesome fight. *spoiler end*
