Roppa ,from the movie "Azumi 2"is a giant of a ninja and his weapon of choice is a big,heavy and thick barbarian staff sword with massive cutting blades at both ends of his metal staff.He like to throw it like Xena would her chackram disc.The momentum is powerful enough to slice thick trees in its path.He catches it like a boomerang.How would Batman and his batarangs or any other marvels in his utility belt do against such a weapon?
