Patapon 2 is filled with powerful monsters and characters who serve as the bosses of the game. Each boss is unique, with different appearances, weaknesses, and attacks. Most bosses have stronger, more vicious cousins that appear in special circumstances or in ancient ruins. Unlike the original game, however, not all of the bosses will be fought during the main story-line. To find certain creatures, you'll have to retrieve their eggs (usually from their weaker or stronger counterparts) and battle them in the Patagate. At Level Ten, most basic bosses gain another, more powerful attack from their stronger cousins.
