Foes are the enemies that the main characters must battle their way through in the Epic Battle Fantasy series. They consist of antagonists, and different species of monsters and mutants. In Epic Battle Fantasy and Epic Battle Fantasy 2, foes approach in waves that must be defeated progressively. Epic Battle Fantasy 3 and Epic Battle Fantasy 4 employ the exploration element, and groups of random foes can be encountered or avoided on the map, each map with its own general elemental types of foes, though some foes may appear in more than one area. Foes also level up and become stronger the farther the game progresses.
