Piko Piko Hammer

The Piko Piko Hammer is a gigantic mallet wielded by Amy Rose. This is her signature weapon, in that she frequently uses it to break objects and crush her enemies (or even simply intimidate them); its power is also capable of creating twisters and shockwaves, as showcased in the past ("Sonic Battle"). The hammer sometimes varies in size—the most radical alteration being the "long hammer," which Amy is seen using during the  Nazca Lines Infiltration . It has been said that she uses this hammer in battle to both impress Sonic and rescue him on occasion.
