Pyrus can be found at the inner core of the universe and is inhabited by Bakugan who draw their strength from the blazing heat that surrounds them. It is within these deep recesses of molten rock that their intensity is forged. Never one to waste even a second, the Pyrus blitz their enemies from every angle like a raging firestorm.
For Pyrus Bakugan, the main point of them is to simply overpower through sheer force and shutting down ways your opponent can fight back like gate card bonuses or Ability Cards. Due to this, nullifying cards like Rikimaru's Surprise or Stand Off are very useful to stop your opponent from fighting back with ability cards or Gate effects and Stand Off also gives a great Pyrus Bonus.
