This article refers to the sub bosses in The Ocean Hunter.
The sub bosses behave much like the Seven Great Monsters, which outrank them, as the overseers of their respective sea, and are as threatening as their superiors. Furthermore, they are far more dangerous than any ordinary aquatic predators and are fundamental to test the skill and potential of the player(s) before the final battle in each stage of the game. With the exception of the Texcoco Great Lake, there is at least one sub boss in each sea.
* Optional sub boss
There are no sub bosses present in this sea.
